Description

  The present invention relates to a gaming machine capable of performing a predetermined game.

  A gaming machine such as a pachinko gaming machine or a slot machine is provided with a number of circuit boards such as a game control board (circuit board) for controlling a game. A control microcomputer including a CPU, a RAM, a ROM, and the like is mounted on the circuit board, and a program (game control program) for controlling the progress of the game is stored in the ROM. When the mounted microcomputer is replaced with a microcomputer in which a malicious program is written, it becomes possible to illegally pay out prizes.

  For example, when a game value is given to a player in a big hit game state or the like, it is easy for the player to obtain a prize. Therefore, there is an act of modifying the game control program executed by the CPU so that “big hit” is likely to occur. In order to prevent game control and the like from being executed by a modified illegal program, a microcomputer generally has a security check function for determining whether or not the program is valid. The microcomputer is configured not to execute the game control program or the like when the security check function determines that the program is not valid.

  However, an illegal act such as removing a regular microcomputer with a built-in program and installing a microcomputer with a built-in fraudulent program that is likely to cause a big hit is conceivable. In a microcomputer incorporating such a malicious program, the security check function does not exist, or even if it exists, it is modified so that the malicious program is determined as a legitimate program. Therefore, there is a possibility that a game due to an unauthorized program cannot be prevented only by the security check function.

  Therefore, when this type of circuit board is stored in a substrate case composed of a base body (first covering body) and a cover body (second covering body) and is opened by applying a seal seal, There is one in which it is possible to easily find out that there is a possibility that an illegal act has been performed on a circuit board by making the sealing state so that a trace remains.

  As a gaming machine equipped with this type of board case, an IC chip unit storing identification information such as a unique ID and an electronic tag including an antenna unit are sealed with a sealing seal embedded therein. By performing a reading operation of the identification information stored in the IC chip unit by a reading device such as a reader device, after the substrate case is opened and replaced with an unauthorized circuit board, an illegal act such as attaching a forged seal sticker is performed. Some of them were able to confirm whether or not they occurred without visual observation (for example, see Patent Document 1).

JP 2008-17914 A

  As in the gaming machine described in the above-mentioned Patent Document 1, when a sealed state is set by a seal seal, the substrate case is opened by peeling off the seal seal to which a third party has been attached using, for example, a solvent. In some cases, it may not be possible to determine that the board case has been opened. there were.

  The present invention has been made paying attention to such problems, and it is easy to determine that the substrate case has been opened even if the seal seal attached to the substrate case is peeled off and then attached again. An object is to provide a gaming machine that can be used.

  The effect control board 90 is connected to effect devices such as a liquid crystal display 51 (see FIG. 1), an effect LED 52, speakers 53 and 54, and the reel LED 55 described above, which are arranged on the front door 1b of the slot machine 1. These effect devices are driven based on control by a later-described sub-control unit 91 mounted on the effect control board 90.

  In this embodiment, the sub-control unit 91 mounted on the effect control board 90 controls the output of the effect devices such as the liquid crystal display 51, effect effect LED 52, speakers 53 and 54, and reel LED 55. However, in addition to the sub-control unit 91, an output control unit that directly controls the output of the effect device is mounted on the effect control board 90 or another board, and the sub-control unit 91 is based on a command from the main control unit 41. The output control unit may determine the output pattern of the effect device, and the output control unit may control the output of the effect device based on the output pattern determined by the sub control unit 91. In such a configuration, the sub control unit 91 and the output control may be performed. The output control of the rendering device is performed by both of the units.

  Further, in the present embodiment, the liquid crystal display 51, the effect effect LED 52, the speakers 53 and 54, and the reel LED 55 are exemplified as the effect device, but the effect device is not limited to these, for example, a mechanically driven display. A device or a mechanically driven item may be applied as the effect device.

  Similar to the main control unit 41, the effect control board 90 includes a sub CPU 91a, ROM 91b, RAM 91c, and a microcomputer provided with an I / O port 91d. The sub control unit 91 controls the effect, and the effect control board 90. A display control circuit 92 that performs display control of the liquid crystal display 51 connected to the LED, an LED driving circuit 93 that performs drive control of the effect LED 52 and the reel LED 55, an audio output circuit 94 that controls audio output from the speakers 53 and 54, Supplied to a reset circuit 95 that gives a reset signal to the sub CPU 91a when the power is turned on or when an initialization command from the sub CPU 91a is not inputted for a certain period of time, a clock device 97 that outputs time information including date information and time information, and a slot machine 1 The power supply voltage is monitored, and when a voltage drop is detected, this is indicated The power interruption detection circuit 98 that outputs a pressure drop signal to the sub CPU 91a, other circuits, and the like are mounted. The sub CPU 91a receives a command transmitted from the game control board 40 and performs an effect. While performing various controls, each part of the control circuit mounted on the effect control board 90 is controlled directly or indirectly.

  Similar to the main CPU 41a, the sub CPU 91a has an interrupt function (including an interrupt prohibition function). One of the interrupt terminals of the sub control unit 91 is connected to a strobe (INT) signal line that is output when the main control unit 41 transmits a command, among the command transmission lines, and the sub CPU 91a receives the strobe signal. An interrupt is generated based on the input to acquire a command from the main control unit 41 and execute a command reception interrupt process to be stored in the buffer. Further, the sub CPU 91a executes an interrupt process (sub) to be described later by generating an interrupt every time the number of clock inputs reaches a certain number, that is, every certain interval. One of the interrupt terminals of the sub-control unit 91 is connected to the power interruption detection circuit 98, and the sub CPU 91a responds to the input of the voltage drop signal output from the power interruption detection circuit 98. Execute processing (sub). Further, when an unused interrupt occurs in the sub CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

  The sub-control unit 91 is also supplied with backup power at the time of a power failure, and the data stored in the RAM 91c is held while the backup power is supplied.

  In the slot machine 1 of the present embodiment, various boards such as the game control board 40 provided with the main control unit 41 for controlling the game are mounted as described above, and these boards are shown in FIG. As described above, electrical components such as switches that can be operated by a player are connected via a cable.

  As described above, on the game control board 40, the single BET switch 5, the MAXBET switch 6, the start switch 7, the stop switches 8L, 8C, 8R, the insertion medal sensor 31, the reel motors 32L, 32C, 32R, and the reel sensor 33L. 33C, 33R, a hopper motor 34b, a payout sensor 34c, and an effect control board 90 are connected.

  Specifically, as shown in FIG. 4, the start switch 7 is connected to the game control board 40 by wiring, and the one-sheet BET switch 5, the MAXBET switch 6, the stop switches 8L, 8C, 8R, the insertion medal sensor 31, and the door open. The detection switch 25 is connected to the game control board 40 via the operation unit relay board 110, and the reel motors 32L, 32C, 32R and the reel sensors 33L, 33C, 33R are used for game control via the reel relay board 120. The hopper motor 34b and the payout sensor 34c are connected to the game control board 40 via the power supply board 101, and the effect control board 90 is connected to the game control board 40 via the effect relay board 80. And wired connection.

  The operation unit relay board 110, the reel relay board 120, the power supply board 101, and the effect control board 90 are provided with wiring patterns (not shown) for connecting the game control board 40 and each electrical component. The detection signal output from the component to the game control board 40 or the power or signal supplied (input) from the game control board 40 can be relayed.

  In this way, the relay boards 110, 120, 100, and 80 in which the various electrical components except the start switch 7 and the game control board 40 are attached to the main body of the slot machine 1 (the casing 1a in the present embodiment) at predetermined positions are attached. By connecting via the wiring, it is easy to organize wiring from the game control board 40 to a plurality of electrical components individually arranged at predetermined positions of the main body of the slot machine 1, and the connector connection portion is always connected to the relay board. Or, it will be provided on the game control board 40, so that the connector connection portion of each electric component is fixed, so that the connector connection portion may be searched at the time of wiring connection work, or the type of wiring to be connected may be wrong. Is prevented.

  Single BET switch 5, MAXBET switch 6, start switch 7, stop switches 8L, 8C, 8R, insertion medal sensor 31, reel motors 32L, 32C, 32R, reel sensors 33L, 33C, 33R, hopper motor 34b, payout sensor 34c Is an electrical component that inputs and outputs signals relating to the progress of the game to and from the game control board 40. The signal related to the progress of the game is, for example, an operation for setting the number of bets to make the game startable, an operation for starting the game, or an operation for deriving the display results of the reels 2L, 2C, and 2R. Such as signals output to the game control board 40 in accordance with the progress of the game, detection of inserted medals, detection of the reference position of the reels, detection of the payout medals, etc., output from the electrical components for gaming according to the progress of the game And a signal input to the game control board 40, a drive signal for driving the reels 2L, 2C, 2R according to the detection of the start operation, and a hopper for paying out medals when a winning occurs. A signal that is output from the game control board 40 in accordance with the progress of the game and that is input to the game electrical component, such as a drive signal.

  These gaming electrical components are a first electrical component that outputs a signal to the game control board 40 as the game progresses, and a second that receives a signal from the game control board 40 as the game progresses. And electric parts.

  The gaming electrical component and the board are connected via a cable, and the cable connecting the gaming electrical component and the board is designed to facilitate assembly work and wiring work during manufacturing of the slot machine. Separation is possible by releasing the connection. In addition, these electrical parts for gaming are basically electrical parts that continue to be used in common for multiple models, and there are few opportunities to remove them from the main body and replace them unless a failure occurs. It is fixed in place. On the other hand, the game control board 40, the effect control board 90, and the like need to be replaced when changing the model, and are removed from the main body at that time. In other words, when removing the game control board 40, it is necessary to release the connection between the game electrical parts and the effect control board 90, so the cables and boards that connect these boards and the board and the game electrical parts are The cable side connector provided at the end of the cable is electrically connected to the board side connector electrically connected to the wiring pattern of the board, and the cable side connector is removed from the board side connector. By releasing the connection, the game control board 40 can be easily removed from the main body and replaced.

  However, when the slot machine is shipped from the manufacturer to the game store in such a state that the wiring connection between the game control board 40 and the electrical component for gaming can be easily released by removing the connector, for example, in the game store, the board side connector In this case, the cable-side connector can be easily removed from the board-side connector, and the cable-side connector connected to an unauthorized tool such as a so-called driving tool can be easily connected to the board-side connector.

  The driving instrument is, for example, a switch that is provided in the slot machine by causing the game control board 40 to input / output a signal that simulates a signal input / output to / from the game control board 40 from an electrical component for gaming. The game can be automatically advanced without operation. Therefore, for example, in a game store or the like, the regular connector connected to the board-side connector provided on the game control board 40 is removed, and an unauthorized connector connected to the driving tool is connected instead. By inputting / outputting signals to / from the game control board 40 at an appropriate timing to automatically advance the game, for example, it is possible to easily set a state where a special role is won. Therefore, a slot machine set in a state in which a special role is won using such an illegal driving tool, and BB (Regular Bonus) and BB (Big Bonus) with higher advantage are won. If the slot machine set to a state where there is a high possibility of being present is provided to a player at the start of business at a game store, for example, the fairness of the game may be impaired.

  For this reason, in this embodiment, as described above, only the start switch 7 of the electrical components for gaming is directly connected to the game control board 40, and the connector connection between the game control board 40 and the start switch 7, that is, Regarding the connection between the board-side connector 620b of the game control board 40 and the cable-side connector 610b of the cable 600b and the connection between the component-side connector 640b of the start switch 7 and the cable-side connector 630b, the connection between the connectors is released. Can be regulated by.

  Here, the connector restricting member 650 for restricting the release of the connection between the board-side connector 620b and the cable-side connector 610b of the cable 600b is formed in a box shape with one surface open (see FIG. 5), and is connected to the board-side connector 620b. The elastic claw 237a provided in the engagement cylinder 237 is engaged with an engagement hole (illustrated) by fitting in an engagement cylinder 237 of a cover member 202 described later in a state where the cable side connector 610b is covered from above. And is attached to the cover member 202.

  By fitting the connector restricting member 650 into the engaging cylinder 237 in this way, the elastic claw 237a is engaged with an engaging hole (not shown) in the inside thereof, whereby the cover member 202 is opened or engaged. Since the engaged state cannot be released from the outside unless the portion is destroyed, the release restricting portion must be destroyed in order to release the connector connection between the game control board 40 and the start switch 7. As a result, when the connector connection between the game control board 40 and the start switch 7 is released, the trace remains and it is extremely difficult to erase the trace. Can be suppressed.

  The connector restricting member 650a for restricting the release of the connection between the component side connector 640b and the cable side connector 630b of the start switch 7 is not particularly shown, but is removed unless a predetermined release restricting portion related to the release of the connection is destroyed. What is necessary is just to be comprised so that attachment is possible in the attachment state which cannot do.

  In this embodiment, the game control board 40 and the start switch 7 are connected without going through the relay board, and the connector connection only needs to be made on the game control board 40 and the electrical component (start switch 7) side. Wiring connections are simplified, but when connecting via one or more relay boards, it is preferable to regulate the removal of all connector connections that exist between them. Since it becomes difficult to release the connection of any of the connectors between the game control board 40 and the start switch 7, the illegal business can be prevented more effectively.

  In the present embodiment, the first electric components 5, 6, 7, 8, 31, 33L, 33C, 33R, and 35 that input signals to the game control board 40 in accordance with the progress of the game and the progress of the game. Of the second electrical components 32L, 32C, 32R, 34 for which a signal is output from the game control board 40 in response to this, a connector restricting member 650 is provided only for connector connection between the start switch 7 and the game control board 40. The release of connection between connectors is regulated. That is, a start switch 7 (one that cannot start a game unless a signal is input from the start switch 7) and a game control board are electrical components that cannot advance the game without the signal. The connector restricting member 650 is provided only for connector connection with the connector 40 to restrict the connection between the connectors, and the connection between the connectors between the other electrical components and the game control board 40 is released to drive the instrument. Even if it is replaced with a connector, it will be impossible to automatically advance the game automatically, so that it is possible to prevent fraud with the minimum restrictions, and to disconnect these connectors The number of parts can be reduced.

  In this embodiment, only the connector connection between the start switch 7 and the game control board 40 is provided with the connector restriction member 650 to restrict the release of the connection between the connectors, but the inserted medal sensor 31 and the game control board The same effect can be obtained by providing a connector restricting member only for connector connection between the connectors 40 and restricting the release of the connection between the connectors. Further, if the reel is not configured to stop until the reel stop operation is performed after the start of the reel rotation as in the present embodiment, between the stop switch 8L, 8C, 8R and the game control board 40. The same effect can be obtained even if the connector restricting member is provided only for the connector connection to restrict the release of the connection between the connectors.

  In this embodiment, the door opening detection switch 25 is connected to the game control board 40 via a cable. However, any of the connectors of the cable provided between the door opening detection switch 25 and the game control board 40 may be used. When the connection at that connector is released, when the front door 1b is opened, the main control unit 41 mounted on the game control board cannot detect that fact, and the door opening notification or door opening is detected. Since the output of the signal is not performed, the discovery may be delayed even if the front door 1b is opened and an illegal act is performed. Therefore, the connector connection between the game control board 40 and the door opening detection switch 25 is not possible. A connector restricting member may be provided to restrict the release of the connection between the connectors. By doing so, the game control board 40 and the door opening detection switch 25 may be restricted. It becomes difficult to release the one of connector connection between, with no been informed to the effect that the opening of the front door 1b, can be effectively prevented front door 1b from being opened.

  Further, in this embodiment, a plurality of signal lines connecting the main control unit 41 and a plurality of electrical components other than the start switch 7 for inputting and outputting signals necessary for the progress of the game and the door opening detection switch 25 are provided. Since the game control board 40 and the operation unit relay board 110 are connected by a single cable 600a, the connector connection between the board-side connector 620a and the cable-side connector 610a of the game control board 40, that is, one connector By restricting the release of only the connection, it becomes possible to restrict the release of the connection between the signal lines, and it is not necessary to prepare multiple parts for restricting the release of these connector connections. The score can be reduced.

  When a plurality of signal lines connecting the main control unit 41 and a plurality of electrical components for inputting / outputting signals necessary for the progress of the game and the door opening detection switch 25 are connected via a plurality of cables. However, in order to regulate the release of these connector connections by arranging the board side connectors close to each other and restricting the release of the connection between the plurality of board side connectors and the plurality of cable side connectors with one component. It is not necessary to prepare a plurality of parts, and the number of these parts can be reduced.

  The slot machine 1 according to the present embodiment outputs an external output signal indicating a gaming state, an error occurrence state, and the like. These external output signals are output from the game control board 40 under the control of the main CPU 41a, and the hall computer is provided via the external output board 1000 and the information providing terminal board (not shown) of the game store (hall) where the slot machine 1 is installed. It is output to hall equipment such as (not shown).

  From the game control board 40 to the external output board 1000, a medal IN signal indicating the number of medals used for setting the number of bets, a medal OUT signal indicating the number of medals given to the player due to the occurrence of a winning, a gaming state RB signal indicating that RB is described later, a BB signal indicating that the gaming state is BB described later, a door opening signal indicating that the front door 1b is open, and a setting change mode described later. A setting change signal indicating that the medals are in error, an insertion error signal indicating an abnormality in the medal selector, and a payout error signal indicating an abnormality in the hopper unit 34 are output.

  In the slot machine 1 of the present embodiment, the medal payout rate changes according to the set value. Specifically, the medal payout rate is changed by using a winning probability corresponding to a set value in an internal lottery described later. The set value is composed of 6 levels of 1 to 6, with 6 being the highest payout rate and the payout rate being lower as the value is decreased in the order of 5, 4, 3, 2, 1. That is, when 6 is set as the set value, the advantage is highest for the player, and as the value decreases in order of 5, 4, 3, 2, 1, the advantage decreases stepwise.

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 after the setting key switch 37 is turned on. When the setting key switch 37 is turned on and the power is turned on, the setting value read from the RAM 41c is displayed on the setting value display 24 as a display value, and the setting value can be changed by operating the reset / setting switch 38. Transition to the setting change state. When the reset / setting switch 38 is operated in the setting change state, the display value displayed on the setting value display 24 is updated one by one (when further operation is performed from the setting 6, the display returns to the setting 1). . When the start switch 7 is operated, the display value is determined as the set value. Then, when the setting key switch 37 is turned OFF, the determined display value (setting value) is stored in the RAM 41c of the main control unit 41, and the state shifts to a state in which the game can proceed.

  In order to confirm the set value, after the game is over, the setting key switch 37 may be turned on with no bet amount set. When the setting key switch 37 is turned on in such a situation, the setting value read out from the RAM 41c is displayed on the setting value display 24, thereby shifting to a setting confirmation state in which the setting value can be confirmed. In the setting confirmation state, the game cannot be progressed, and by turning the setting key switch 37 to the OFF state, the setting confirmation state is ended and the state in which the game can proceed is returned.

  In the slot machine 1 of the present embodiment, when the main CPU 41a detects a voltage drop signal from the power interruption detection circuit 48, a power interruption interrupt process (main) is executed. In the power interruption interrupt processing (main), the register is saved in a stack of a RAM 41c, which will be described later, and data for destructive diagnosis (in this embodiment, 5AH) in which any bit is 1 in the RAM 41c, that is, a specific value other than 0 In addition to storing data, the RAM parity adjustment data is calculated so that the RAM parity based on the data stored in all areas of the RAM 41c is 0, and the RAM 41c is stored. The RAM parity is a value calculated as an exclusive OR of values stored in each bit of the corresponding area (all areas in this embodiment) of the RAM 41c. Therefore, if the RAM parity based on the data stored in all areas of the RAM 41c is 0, the RAM parity adjustment data is 0, and the RAM parity based on the data stored in all areas of the RAM 41c is 1. In this case, the RAM parity adjustment data is 1.

  The main CPU 41a calculates the RAM parity based on the data stored in all areas of the RAM 41c at the time of activation, confirms the value of the destructive diagnosis data, the RAM parity is 0, and the destructive diagnosis The processing state of the main CPU 41a is restored to the state before the power interruption based on the data stored in the RAM 41c on the condition that the value of the data for use is correct, but the RAM parity is not 0 (in the case of 1) or is destroyed. If the value of the diagnostic data is not correct, it is determined that the RAM is abnormal, and the RAM abnormal error code is set in the register to control the RAM abnormal error state so that the progress of the game is disabled. Unlike the other error states, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and a new set value is set in the setting change state described above. It will not be released until

  In this embodiment, all the data stored in the RAM 41c is held by the backup power source even in the event of a power failure, and when the main CPU 41a determines that the data in the RAM 41c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 41c, only the data necessary for the restoration of the control state in the event of a power failure is backed up among the data stored in the RAM 41c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player For example, it is not necessary to restore the state of all input ports to the state before power interruption.

  In addition, when the sub CPU 91a detects the voltage drop signal from the power interruption detection circuit 98, the sub CPU 91a also executes a power interruption interrupt process (sub). In the power interruption interrupt processing (sub), the register is saved in a stack of a RAM 91c described later, and destructive diagnosis data in which any bit is 1 is stored in the RAM 91c, and data stored in all areas of the RAM 91c. The RAM parity adjustment data is calculated so that the RAM parity based on 0 becomes 0 and stored in the RAM 91c.

  Then, the sub CPU 91a calculates the RAM parity based on the data stored in all areas of the RAM 91c at the time of activation, and based on the data stored in the RAM 91c on the condition that the RAM parity is 0. The processing state of the sub CPU 91a is restored to the state before the power interruption. If the RAM parity is not 0 (1), it is determined that the RAM is abnormal and the RAM 91c is initialized. In this case, unlike the main sub CPU 91a, the execution of the performance is not disabled only by initializing the RAM 91c.

  In this embodiment, all data stored in the RAM 91c is held by the backup power source even during a power failure, and the sub CPU 91a determines that the data in the RAM 91c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 91c, only the data necessary for restoration of the control state is backed up in the event of a power failure out of the data stored in the RAM 91c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player It is not necessary to restore the state of the input port or the progress in the middle of the production when it is interrupted. For example, only data indicating the gaming state such as during a big bonus or a normal gaming state is backed up, and an effect corresponding to the gaming state (a big bonus during a big bonus, normal during a normal gaming state) If a power interruption occurs during the execution of a specific production (such as a small role announcement) other than the production), when the power is turned on instead of resuming the specific production that was being performed at the next power-on An effect corresponding to the gaming state being backed up may be executed from the beginning.

  Next, initialization of the RAM 41c of the main control unit 41 will be described. The storage area of the RAM 41c of the main control unit 41 is divided into an important work, a general work, a special work, a set value work, a non-saved work, an unused area, and a stack area.

  The important work is a work that stores data that is inconvenient to be initialized at the end of the big bonus, such as various display devices and LED display data, input / output data of the I / O port 41d, and a game time counter. The general work is a work in which data that can be initialized at the end of the big bonus, such as a stop control table, a stop symbol, the number of medals paid out, and the total number of medals paid out in the big bonus, are stored. The special work stores data that is not initialized even before the setting is changed, such as data for transmitting a command to the effect control board 90 and various software random numbers (a random number for determination value addition described later, a random number for changing an initial value). Work. The set value work is a work that stores a set value used when a lottery is performed in the internal lottery process. The unsaved work is a work that holds the state of various switches, and a value is always set regardless of whether or not the data in the RAM 41c is destroyed at the time of activation. The unused area is an unused area in the storage area of the RAM 41c, and is initialized if any one of a plurality of initialization conditions described later is satisfied. The stack area is an area in which data saved from the register of the main CPU 41a is stored, and the unused stack area is established by any one of a plurality of initialization conditions to be described later, like the unused area. In this case, the used stack area is not initialized because the program continues.

  In this embodiment, the main CPU 41a destroys data in the RAM 41c when a RAM abnormality error occurs, when the setting key switch 37 is activated with the setting key switch 37 turned on, when the big bonus is completed, and when the setting key switch 37 is activated with the setting key switch 37 turned off. If not, when five initialization conditions at the end of one game are satisfied, five types of initialization that are initialized in different areas are performed according to each initialization condition.

  Initialization 0 is initialization that is performed when a RAM abnormality error occurs. In initialization 0, all the areas (including the unused area and the unused stack area) of the storage area of the RAM 41c except the used stack area are stored. It is initialized. Initialization 1 is an initialization that is performed before the setting key switch 37 is turned on at the time of startup and shifts to the setting change state. In the initialization 1, a special area in the storage area of the RAM 41c is selected. Areas other than the work, the unsaved work, and the used stack area (including the unused area and the unused stack area) are initialized. Initialization 2 is initialization performed at the end of the big bonus. In initialization 2, the general work, the unused area, and the unused stack area are initialized in the storage area of the RAM 41c. Initialization 3 is initialization that is performed when the setting key switch 37 is in an OFF state at the time of startup and the data in the RAM 41c is not destroyed. The used stack area is initialized. Initialization 4 is initialization performed at the end of one game. In initialization 4, an unused area and an unused stack area in the storage area of the RAM 41c are initialized.

  In this embodiment, initialization 1 is performed before the change of the setting change state. However, the initialization 1 is performed at the end of the setting change state, or both before the change of the setting change state and at the end of the setting change state. Also good. In this case, if the set value work is initialized, the determined set value is lost. Therefore, the initialization of the set value work is not performed in the initialization at the end of the setting change state.

  In the slot machine 1 according to the present embodiment, as described above, the specified number of bets that can be set according to the gaming state is determined, and the specified number of bets determined according to the gaming state is set. It becomes possible to start the game on the condition. In this embodiment, there are regular bonuses (hereinafter referred to as RB) (big bonuses (hereinafter referred to as BB)) and RT (0) to (6) as gaming states, of which RB (BB) is the number of bets. 1 is defined as the specified number of bets, and 3 is defined as the specified number of bets in RT (0) to (6). Therefore, if the gaming state is RB (BB), it is possible to start the game when 1 is set as the bet number, and 3 is set as the bet number if RT (0) to (6). Then, the game can be started. In this embodiment, the winning line L is activated when a specified number of bets corresponding to the gaming state is set, and 1 is set as the bet number in RB (BB). All winning lines L1 to L5 are activated at the time when the winning numbers are reached, and all winning lines L1 to L5 are activated when 3 is set as the betting number in RT (0) to (4). It becomes.

  The slot machine 1 according to the present embodiment plays a role on an activated pay line (hereinafter, the activated pay line is simply referred to as a pay line) when all the reels 2L, 2C, 2R are stopped. A winning combination will be awarded when all the combinations of symbols are called. The combination may be a combination of the same symbols or a combination including different symbols. The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition of the game state. Below, a small role and a re-playing role are collectively called a general role. In order for winning of each combination determined according to the gaming state to occur, it is necessary to win an internal lottery to be described later and set a winning flag of the combination in the RAM 41c.

  Of the winning flags for each of these combinations, the winning flag for the small role and the re-playing role is valid only in the game in which the flag is set, and is invalid in the next game. It is valid until a combination of combinations permitted by the flag is completed, and is invalid in a game having a combination of combinations permitted. In other words, once the special combination winning flag is won, even if the combination of the combinations permitted by the flag cannot be made, the winning flag is not invalidated and is carried over to the next game. It becomes.

  In the internal lottery, it is determined whether or not the above winning combination is permitted before the display results of all the reels 2L, 2C, and 2R are derived and displayed (actually, when the start switch 7 is detected). To do. In the internal lottery, first, a random number for internal lottery (an integer from 0 to 65535) is acquired. Then, for each combination determined according to the gaming state and whether or not the special combination is carried over, the acquired random number for internal lottery and the number of judgment values for each combination determined according to the gaming state, the number of bets and the set value Is done according to.

  In this embodiment, whether the gaming state is RT (0) (1) (not carrying a special role) or RT (2) (4) (5) (not carrying a special role) Depending on whether it is RT (3) (not carrying over a special combination), RT (6) (while carrying a special combination) or RB (BB), the combination that is subject to internal lottery differs.

  In the internal lottery, the number of determination values determined corresponding to the role to be subject to the internal lottery, the current gaming state and the set value are sequentially added to the random number for the internal lottery, and when the result of addition overflows, It is determined that the winning combination has been won. For this reason, a winning combination will be won with a probability (number of determination values / 65536) according to the number of determination values.

  If a winning combination of any combination is determined, a winning flag corresponding to the combination determined to be winning is set in the internal winning flag storing work assigned to the RAM 41c. The internal winning flag storage work consists of a 2-byte storage area, of which the upper byte is assigned as the special role storing work in which the winning flag for the special role is set, and the lower byte is the winning of the general role It is assigned as a general role storage work for which a flag is set. Specifically, when a special combination is won, a special combination winning flag indicating that the special combination is won is set in the special combination storing work, and the winning flag set in the general combination storing work is cleared. When a general combination is won, a winning flag for the general combination indicating that the general combination is won is set in the general combination storing work. If no winning combination is selected, only the general winning combination work is cleared.

  Next, stop control of the reels 2L, 2C, 2R will be described.

  The main CPU 41a refers to the table index and the table creation data stored in the ROM 41b when the rotation of the reel starts and when the reel stops and the reel that is still rotating still remains. Create a stop control table for each reel. When any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to and the slip of the referred stop control table is referred to. Based on the number of frames, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

  In the table index, an index that indicates the start address of the area in which the data for table creation is stored, from the reference address when referring to the table index, according to the setting state of the winning flag by internal lottery (hereinafter referred to as the internal winning state) Differences up to the address where the data is stored are registered. As a result, a difference corresponding to the internal winning state is acquired, and the corresponding index data can be acquired by adding the difference to the reference address. Even when the winning combinations are different, when the same control is applied, the same address is stored as the index data. In such a case, the same table creation data is referred to. Thus, a stop control table is created.

  The table creation data includes a stop control table indicating the number of sliding frames according to the stop operation position, and an address of the stop control table to be referred to according to the reel stop status.

  The stop control table referred to according to the reel stop status is whether all reels are rotating, only the left reel is stopped, only the middle reel is stopped, only the right reel is stopped, It may vary depending on whether the middle reel is stopped, the left and right reels are stopped, the middle and right reels are stopped, and if any reel is stopped, stop Since there may be differences depending on the stop position of the reels already completed, the address of the stop control table to be referenced for each situation is registered for each rotating reel, and based on the top address of the table creation data, It is possible to specify the address of the stop control table that should be referred to according to the status of each, and it is necessary according to each status from this specified address. And to be able to identify the stop control table. Even when the reel stop status and the stopped position of the stopped reel are different, when the same stop control table is applied, the same address may be registered as the address of the stop control table. In such a case, the same stop control table is referred to.

  The stop control table is data that can specify the number of sliding frames for each timing when the stop operation is performed. In this embodiment, stepping motors that make one turn at a cycle of 168 steps (0 to 167) are used for the reel motors 32L, 32C, and 32R. That is, when the reel motors 32L, 32C, and 32R are driven for 168 steps, the reels 2L, 2C, and 2R make one round. 21 areas (frames) divided every 8 steps (the number of steps in which one symbol moves) per reel are defined, and these areas are areas 0 to 20 from the reel reference position. A number is assigned. On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 0 to 20 from the reel reference position are assigned to symbols on each reel, so symbols 0 to 20 are assigned to each reel. , Area numbers 0 to 20 are assigned in order. In the stop control table, the number of sliding symbols for each area number is compressed and stored according to a predetermined rule, and the number of sliding symbols for each area number can be acquired by expanding the stop control table. Yes.

  As described above, the stop control table created by referring to the table index and the table creation data corresponds to the area number, and the area corresponding to each area number is the stop reference position (in this embodiment, the perspective window 3). Sliding frame when an operation of the stop switches 8L, 8C, 8R is detected at a timing (a timing in which the number of steps from the reel reference position is included in the range of the number of steps of each region number). It is a table with each number set.

  Next, the procedure for creating the stop control table will be described. First, at the start of reel rotation, the top address of the table creation data corresponding to the internal winning state of the game is acquired. Specifically, the table index is first referred to, index data corresponding to the internal winning state is obtained, table creation data is identified based on the obtained index data, and all reels are identified from the identified table creation data. The address of the stop control table for each reel corresponding to the state of rotation is acquired, and the stop control table for each reel stored at the acquired address is expanded to generate a stop control table for all reels.

  Further, when any one reel stops or any two reels stop, the index data acquired at the start of reel rotation, that is, the top address of the table creation data corresponding to the internal winning state of the game The table creation data is identified based on the table creation data, and the stop control table address of the unreacted reel corresponding to the stopped reel and the area number of the stop position of the reel is obtained from the identified table creation data. The stop control table for each stored reel is expanded to create a stop control table for the unstopped reels.

  Next, when the main CPU 41a effectively detects any one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel, the control when the display result is derived to the corresponding reel will be described. When one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop operation position area is determined based on the number of steps from the reel reference position when the stop operation is detected. The number is specified, the stop control table of the reel where the stop operation is detected is referred, and the number of sliding symbols corresponding to the area number of the specified stop operation position is acquired. Then, control is performed to rotate and stop the reel by the number of acquired sliding frames. Specifically, from the number of steps from the reel reference position at the time when the stop operation is detected, the number of steps from the acquired number of sliding frames to the stop is calculated, and the reel is rotated and stopped by the calculated number of steps. Take control. As a result, the area corresponding to the area number that is the stop position ahead of the number of sliding frames from the area corresponding to the area number of the stop operation position where the stop operation is detected is the stop reference position (in this embodiment, the perspective window 3 It will stop in the lower symbol area).

  In the table index of this embodiment, only one address is stored as index data corresponding to one internal winning state in one gaming state, and further, one table creation data includes one reel. Only one address is stored as the address of the storage area of the stop control table corresponding to the stop status (and the stop position of the stopped reel). In other words, table creation data corresponding to one internal winning state in one gaming state and stop control tables corresponding to reel stop states (and stopped positions of stopped reels) are uniquely determined. The stop control table created with reference to is unique for one internal winning state in one gaming state and the reel stop status (and the stop position of the stopped reel). Therefore, when all of the gaming state, the internal winning state, and the reel stop status (and the stop position of the stopped reel) are the same, the reel is based on the same stop control table, that is, the same control pattern. The stop control is performed.

  Further, in this embodiment, a value of 0 to 4 is determined as the number of sliding frames, and the reel can be stopped by drawing a maximum of 4 symbols after detecting the stop operation. In other words, the stop position of the symbol can be designated from a range of a maximum of 5 frames including the stop operation position where the stop operation is detected. In addition, since it is necessary to move one frame to move the reel for one symbol, it is possible to stop the reel by pulling in a maximum of four symbols after detecting the stop operation. The symbol stop position can be designated from a range of up to five symbols including the operation position.

  In this embodiment, when any of the winning combinations is won, the winning combination is drawn on the winning line to the maximum in the range of 4 frames, and the winning combination is aligned on any winning line. Create a stop control table that defines the number of sliding frames to be pulled in to prevent reels from being stopped, and if none of the winning combinations are selected, slipping that does not match any winning combination on the winning line A stop control table with a defined number of frames is created and reel stop control is performed. As a result, when a stop operation is performed, if a winning combination can be stopped on any winning line in a drawing range of a maximum of 4 frames, control is performed to align and stop them. In this case, the winning combination is controlled so that the winning combination is stopped within a drawing range of a maximum of 4 frames.

  If the special role is elected while the special role has been carried over from before the previous game, or if the special role and the small role are elected at the same time when the special role is not carried over, the special role and the small role are won simultaneously. The number of sliding symbols is set so that the winning small role is drawn to the winning line within the range of 4 frames, and the winning small role is drawn to the winning line within the range of up to 4 frames. For stop operation positions that cannot be inserted, a stop control table in which the number of sliding symbols is determined so as to draw the selected special combination to the winning line in the range of 4 frames to the maximum is created, and reel stop control is performed. As a result, when a stop operation is performed, if it is possible to stop all the small roles that have been selected in the drawing range of up to 4 frames on the winning line and stop them, control is performed so that the winning combination is stopped. If you can't draw a small role that has been won in the drawing range of up to 4 frames on the line, if you can stop with a special role that has been won in the drawing range of up to 4 frames on the winning line, A control is performed to stop them in a uniform manner, and a winning combination that has not been won will be controlled to be stopped within a 4-frame pull-in range. That is, in such a case, priority is given to the control for aligning the small combination on the winning line over the special combination, and the special combination can be won only when the small combination cannot be drawn.

  In this embodiment, when a special role and a small role are simultaneously elected, the control for aligning the small role on the winning line is prioritized over the special role, and the special role is given only when the small role cannot be drawn. However, priority is given to the control of aligning the special role on the winning line over the small role, and it is possible to win the small role only when the special role cannot be drawn. It is good also as a structure.

  The special role and re-playing role are selected when the re-playing role is elected while the special role has been carried over from before the previous game, or when the special role and re-playing role are won at the same time without the special role being carried over. In the case of winning at the same time, when a stop operation is performed, control is performed so that the symbols of the re-gamer are aligned and stopped on the winning line within a drawing range of a maximum of 4 frames. In this case, the symbols constituting the re-playing combination are arranged within 5 symbols for each of the reels 2L, 2C, and 2R, that is, with an interval of 4 frames or less. Therefore, if a special combination and a replaying player are elected at the same time, the replaying game will always be awarded regardless of the operation timing of the stop switches 8L, 8C and 8R by the player. Will be. That is, in such a case, the control for aligning the re-games on the winning line has priority over the special game, and the re-games will always win.

  In this embodiment, after the rotation of the reels 2L, 2C, and 2R is started, the main CPU 41a continues to rotate the reels for which the stop operation has not been detected until the operation of the stop switches 8L, 8C, and 8R is detected. On the condition that the operation of the stop switches 8L, 8C, 8R is detected, control is performed to stop the display result on the corresponding reel. Even if the reel rotation temporarily stops due to the occurrence of a reel rotation error, the stop operation is still detected until the operation of the stop switches 8L, 8C, and 8R is detected after the reel rotation is restarted. Control is performed to stop the display result of the corresponding reels on the condition that the rotation of the reels that have not been continued is continued and the operation of the stop switches 8L, 8C, and 8R is detected.

  In this embodiment, control is performed to stop the display result on the corresponding reel on condition that the operation of the stop switches 8L, 8C, and 8R is detected. However, the rotation of the reel is started. When a predetermined automatic stop time has elapsed, even if the reel stop operation is not performed, it is assumed that the stop operation has been performed, and automatic stop control is performed to automatically stop each reel. May be. In this case, since the reels are stopped without the player's operation, it is preferable to derive a display result that does not constitute any combination even if any combination is won.

  In the present embodiment, the main CPU 41a sends a BET command, a credit command, an internal winning command, a reel rotation start command, a reel stop command, a winning determination command, a payout start command, a payout end command, a game state command to the effect control board 90. A plurality of types of commands including a standby command, an abort command, an error command, a return command, a setting start command, a confirmation start command, a confirmation end command, and an operation detection command.

  These commands are composed of 1-byte type data indicating the type of command and 1-byte extension data indicating the content of the command, and the sub CPU 91a can determine the type of command from the type data.

At this time, the outer surface of the side wall 201b of the base member 201 is covered by the side wall 202c of the cover member 202. In this state, the cover member 202 is slid in the longitudinal direction (toward the right side in FIG. 6) toward the right side.

  When each engagement piece 220 comes into contact with the end portion of each engagement groove 250 and the right end portion of the cover-side welded portion 223 comes into contact with a restriction piece (not shown), the sliding movement is restricted. On the short side, the locking pieces 203, 203 of the base member 201 are inserted into the cover member insertion holes 222, 222. Thus, each engagement piece 220 is engaged with each engagement groove 250, the right end portion of the cover-side welded portion 223 is locked to the restriction piece (not shown), and the locking pieces 203 and 203 are inserted into the cover member. The cover member 202 is assembled to the base member 201 by being inserted into the holes 222, 222, the assembly position of the cover member 202 with respect to the base member 201 is determined, and the base member 201 and the cover member 202 are aligned (combined). ) To be in a closed state (locked state) in which the opening of the base member 201 is closed, and a state to be described later is possible (see FIGS. 9 and 10).

  As described above, in order to open the cover member 202 from the closed state, the substrate case 200 according to the present embodiment first has to slide the cover member 202 along the base plate 201a of the base member 201. On the other hand, the cover member 202 cannot be locked or released from the locked state, and the locking action effectively restricts the separation of the cover member 202 from the base member 201, that is, lifting.

  Further, in the closed state, the mounting hole 234 of the preliminary sealing piece 232 is disposed at a position facing the screw hole 210, the mounting hole 227 is disposed at the position facing the screw hole 209, and the cover-side welded portion 223. Is disposed at a position facing the base-side welded portion 207 (see FIG. 10A).

  Here, for example, when the game control board 40 is stored in the board case 200 and shipped to a game store or the like by a manufacturer or the like, the cover-side welded part 223 and the base-side welded part 207 are welded, for example. Ultrasonic welding (caulking) is performed using an ultrasonic welding machine or the like (also referred to as a first sealed state). Further, the closing screw 226 is a general screw comprising a rod-like portion having a male screw portion (attachment portion) formed on the outer periphery and a head formed at one end of the rod-like portion and housed in the recess 227a. After the rod-shaped portion of the closing screw 226 is inserted into the mounting hole 227 from the opening 227b of the recess 227a and screwed into the screw hole 209, the sealing seal 400 is placed so as to straddle the cover side sealing portion 224 and the base side sealing portion 229. A U-shaped seal protective cover 228 made of a synthetic resin material is applied to the cover member 202 so as to cover the affixed seal seal 400 while forming a sealed state (also referred to as a second sealed state or a sealed state). And the base member 201 are sandwiched and shipped with the sealing seal 400 protected.

(Sealed structure)
Next, the detailed structure of the sealing part and the sealing seal will be described. 15A is a front view showing the structure of a seal seal, FIG. 15B is a rear view showing a state in which ink is dissolved, and FIG. 15C is a sectional view taken along line KK in FIG. 16A is a perspective view showing a state in which the sealing portion is viewed from the front side, and FIG. 16B is a perspective view showing a state in which the sealing portion is viewed from the rear side. 17A is a front view showing the periphery of the seal seal in an enlarged manner, FIG. 17B is a side view showing the periphery of the seal seal in an enlarged manner, and FIG. 17C is a rear view showing the periphery of the seal seal in an enlarged manner. . 18 is an RR cross-sectional view of FIG. FIG. 19 is a TT cross-sectional view of FIG.

  As shown in FIG. 15 (c), the seal seal 400 is composed of an adhesive layer 402 for enabling the seal seal 400 to be pasted, and a seal substrate 401 on which the adhesive layer 402 is formed. A release paper 404 is attached to the surface of the pressure-sensitive adhesive layer 402. The release paper 404 is peeled off when the seal seal 400 is attached to the substrate case 200. The pressure-sensitive adhesive layer 402 is provided over the entire area of the seal substrate 401.

  The seal base material 401 is formed of a flexible base material such as a paper material into which a peeling liquid described later easily penetrates. As these substrates, a resin film such as a polyester film may be used as long as it has fine holes or the like so that it can easily pass through the solution of the stripping solution. These sealing base materials 401 may have a function such as discoloration when heat at a temperature (for example, 50 ° C.) or higher at which the adhesive strength of the pressure-sensitive adhesive layer 402 decreases is applied. By doing so, even when heat is applied so as to illegally peel off the seal seal 400, the discoloration of the seal base material 401 can leave a trace of the fraud.

  In addition, the seal substrate 401 is formed of a material having a strength lower than the adhesive strength of the adhesive layer 402 or formed thinner than the adhesive layer 402, so that the seal substrate 401 is attached to the substrate case 200. When peeled off, the sealing base member 401 is easily broken due to the adhesive strength of the adhesive layer 402.

  As shown in FIGS. 15A to 15C, the surface of the seal substrate 401 on which the pressure-sensitive adhesive layer 402 is not formed is brought into contact with a later-described stripping solution as shown in FIGS. When the seal seal 400 is pasted in a predetermined manner on the substrate case 200 by the special ink that dissolves, the boundary portion Z between the cover member 202 and the base member 201 constituting the substrate case 200 is displayed. (See FIG. 17 (b)) and is printed and formed so as to be arranged at portions not located at the corners C1 and C2 in the seal sticker attaching portion to be described later.

  In other words, as described above, the character “unopened” is printed with special ink that dissolves in a specific stripping solution that can peel off the seal seal 400. The ink layer constituting the “prohibited” character is dissolved in the stripping solution, and the contrast of the character is lowered (see, for example, FIG. 15B). A solvent usage indicator is formed.

  The solvent use display section includes a solvent use display section 450A representing the characters "open" of "unopening", a solvent use display section 450B representing the characters "seal", and a solvent use display section representing the characters "forbidden" 450C and the solvent use display part 450D showing the character of "stop" are comprised.

  Further, on the surface of the seal sticker 400, in addition to the characters "open prohibition" consisting of the solvent use display portions 450A to 450D, a serial number which is identification information for identifying each seal sticker can be read visually. The first identification information display unit 451 that is displayed and the second identification information on which a two-dimensional bar code that can be read by a predetermined reader is displayed by encoding the identification information that can identify each sealed seal. Unlike the above-described special ink, the display unit 452 is made of a curable ink such as an ultraviolet curable ink, and is printed with a durable ink that does not dissolve in the peeling liquid.

  The first identification information display unit 451 is printed with, for example, identification information consisting of a fixed digit of one digit and nine digits of alphanumeric characters. The alphanumeric characters printed on the first identification information display unit 451 are the slot machine 1. It is different for each, and is used as identification information for managing each board case 200 in an amusement store or the like. The second identification information display unit 452 is printed with identification information including a so-called two-dimensional code, and is different from the identification information printed on the first identification information display unit 451.

  Further, hologram display portions A and 453B for preventing counterfeiting are affixed to the surface of the seal sticker 400 so as to cross the diagonal corner portions of the seal sticker 400 in an oblique direction. Since the hologram display portions A and 453B are affixed to a plurality of positions on the seal seal 400, it is more difficult to forge.

  As the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 402 used in the seal seal 400 of the present embodiment, any known acrylic or silicone-based or polyvinyl-based adhesive can be used as long as it has a strong adhesive force and excellent tackiness. A pressure-sensitive adhesive can be suitably used.

  Incidentally, these pressure-sensitive adhesives are preferably those that can be peeled only by a specific stripping solution without being stripped with a commercially available stripping solution as much as possible, for example, a modified polyvinyl alcohol type The pressure-sensitive adhesive is exemplified.

  That is, for the substrate case 200, a polycarbonate resin or acrylic resin, which is usually transparent and has high mechanical strength, is used so that the substrate accommodated therein can be visually confirmed. Since cardnate resin and acrylic resin are easily dissolved in aromatic solvents such as toluene and xylene, simple substances such as methyl ethyl ketone (MEK) and ethyl acetate, and general solvents in which these solvents are mixed, these general solvents If a pressure sensitive adhesive that can be peeled off with the release liquid contained in the substrate is used, the use of the release liquid (peeling solvent) causes the substrate case 200 to dissolve and the transparency to deteriorate, so the substrate case itself must be replaced. End up.

  For this reason, for example, when the seal sticker 400 is mistakenly attached by a manufacturer of a gaming machine or the like, the sticker sticker 400 attached in error can be peeled off without adversely affecting the substrate case 200. In a solvent that does not opacify the polycarbonate resin and acrylic resin constituting the substrate case 200, for example, a single solvent or a mixed solvent such as a polar solvent such as water, an alcohol solvent or a fatty acid solvent, and an adhesive. What added a surfactant or the like for intruding between the bonding surface of the substrate case 200 and reducing the adhesive strength, that is, a specific peeling solution that does not adversely affect the resin constituting the substrate case 200 It is possible to use one that can be peeled off and has high adhesive strength and little deterioration.

  Therefore, the special ink used for the character formation of “opening prohibition” may dissolve or react by contacting with a specific stripping solution that does not adversely affect the resin constituting the substrate case 200. In particular, an ink having a resin component similar to that of the pressure-sensitive adhesive to be used, and a resin that is easily dissolved by a peeling solution as a main component of the varnish, may be used. Ink or the like mixed with microcapsules that develop color in response to fatty acids contained in the stripping solution can be suitably used.

  By doing in this way, even if a manufacturer of a gaming machine or the like applies the seal seal 400 by mistake, the seal seal 400 can be peeled off without replacing the substrate case 200 by using a specific stripping solution. In addition, even if these specific stripping liquids are illegally acquired and used by a third party, the fact that these specific stripping liquids are used is composed of the solvent use display portions 450A to 450D. It becomes possible to specify by changing the character of “unopened”.

  The above-described resin, solvent, and the like are merely examples, and other resins and solvents other than those exemplified may be used as long as they satisfy the above-described characteristics.

  In addition, the special ink used for the character formation of “unopening” indicates that the visual state changes by contacting with a specific stripping solution and dissolving or reacting as shown in FIG. Thus, for example, the special ink used for the character formation of the solvent use display portions 450A and 450B dissolves by contacting with a specific stripping solution and not only changes due to the disappearance of the characters but also thins even if it does not disappear. Including becoming.

  That is, when a predetermined solvent is used in order to reduce the adhesive strength of the seal seal 400, the solvent use display portions 450A to 450D that show traces of the use of the solvent are printed so as to be visible as described above. Including those that show traces of use of the solvent by disappearing or thinning of the characters.

  In addition, as long as the trace in which the solvent was used is shown by a change in the visual state of the solvent use display portions 450A to 450D, the characters printed in a visible state disappear as described above. Including those showing a trace of the use of the solvent by changing to an invisible state. Furthermore, characters printed in an invisible state (for example, characters printed with ink having the same color as the color of the seal substrate 401) change to a visible state in response to the solvent, that is, develop color. This also includes those showing a trace of the solvent being used.

  In addition, when the visual state of the solvent use display portions 450A to 450D changes, the special ink used for character formation of “unopening” dissolves, and the solvent use display portions 450A to 450D disappear or become thin, or color develops. For example, the character color may be changed by reacting with the special ink, or the special ink may be blurred.

  In addition, as long as the solvent use display portion shows a trace of the use of the solvent when a predetermined solvent is used, as described above, the solvent use display portion can be used as a special ink used for character formation of the solvent use display portion. It may be one that dissolves or reacts without contacting the solvent with the special ink, as well as one that dissolves or reacts when the solvent contacts.

  Also, in this embodiment, as an example of the solvent use display portion, the “unopened” character printed with special ink is described, but the character type, the number of characters, and the arrangement position are arbitrary and can be variously changed. It is. Further, the solvent use display portion is not limited to characters, and may be formed of numbers, symbols, designs, decorations, and the like. Moreover, the solvent use display part may be arrange | positioned only in one place even if it is not arrange | positioned in multiple places.

  At the four corners of the seal seal 400, corner-side cuts 408 are formed as fragile portions penetrating from the front surface side of the seal substrate 401 to the back surface side of the adhesive layer 402, respectively. The corner-side cut 408 is formed in a straight line from the corner of the seal seal 400 toward the center. A large number of outer edge notches 409 are formed on the outer edge of the seal seal 400 from the outer end toward the inner side. These outer edge cuts 409 are formed in an acute V shape so as to open from the inside to the outside, and are formed at equal intervals along the outer periphery of the seal seal 400.

  In this embodiment, the corner side cut 408 is described as an example of the weak part, but the weak part may be a part where the mechanical strength of the seal base material 401 of the seal seal 400 is lower than the other parts. For example, it may not necessarily penetrate from the surface side of the sealing base material 401 to the back side of the pressure-sensitive adhesive layer 402. For example, by making a part of the sealing base material 401 thin, it is more fragile than other parts. The part which is formed may be weak, and it may become weak by using the raw material whose intensity | strength is lower than another part for a part of seal base material 401. FIG.

  In addition, the four corners of the seal seal 400 are cut obliquely to form cut-out sides 410. These cut-out sides 410 are arranged to match positioning surfaces 412a and 422a (see FIG. 17), which will be described later, so that the sticking position and sticking direction of the seal seal 400 are determined. Since the pair of adjacent cutout sides 410 and 410 are directed in different directions as described above, the sealing seal 400 can be obtained simply by arranging the pair of cutout sides 410 and 410 according to the corresponding positioning surfaces 412a and 422a. In addition to being able to reliably determine the sticking position and sticking direction, positioning surfaces 412a and 422a are arranged outside the corners of the seal seal 400, so that it is difficult to lift the seal seal 400 from the corners and peel it off. Therefore, the seal seal 400 cannot be easily peeled off. Therefore, when the seal seal 400 is to be peeled from the corner, stress due to the peeling force concentrates on the corner side cut 408 and the outer edge cut 409, so that the seal seal 400 is easily broken.

  As shown in FIGS. 16 to 19, the base-side sealing portion 229 is formed from a substantially rectangular rear sticking surface 229a formed so as to protrude rightward from the short side 201d and from the right end of the rear sticking surface 229a. It has a base side application surface composed of a lower right application surface 229b that is bent toward the rear surface side. A pair of upper and lower positioning protrusions 411 and 411 projecting outward from the rear application surface 229a and the lower right application surface 229b are extended along the upper and lower sides of the rear application surface 229a and the lower right application surface 229b. ing. The positioning ridges 411 and 411 protrude in the outward direction from the surface 400a of the seal seal 400 in a state where the seal seal 400 is applied to the rear application surface 229a and the lower right application surface 229b as described later. The inner surface that has a height and is suspended from the rear sticking surface 229a and the lower right sticking surface 229b is a positioning surface 411a of the seal seal 400.

  Further, triangular positioning corners 412 and 412 projecting inward from each other are formed at the ends of the positioning ridges 411 and 411 on the short side 201d side, and the inner surfaces of these positioning corners 412 and 412 are respectively The positioning surface 412 a faces the cut-out side 410 at the corner of the seal sticker 400.

  The end surfaces of the positioning ridges 411 and 411 and the positioning corners 412 and 412 are contact restriction surfaces 413 that contact an inner surface of a seal protection cover 228 described later, and the positioning corners 412 and 412 on the contact restriction surface 413. Are formed with engaging convex portions 414 and 414 that engage with engaging concave portions 228a formed in the seal protective cover 228, respectively.

  Further, a screw hole 209 to which a closing screw 226 described later is attached is formed at a substantially central position on the front side of the base side sealing portion 229. When the cover member 202 is assembled to the base member 201 and closed, the rear side of the cover side sealing portion 224 is disposed opposite to the front side of the base side sealing portion 229 so that the screw hole 209 is attached. It matches the hole 227.

  On the other hand, the cover-side sealing portion 224 is formed to be bent from the right end of the front sticking surface 224a to the front surface side and a substantially rectangular front sticking surface 224a formed so as to protrude rightward from the side wall 202d. It has a cover side pasting surface composed of an upper right pasting surface 224b. Above and below the front sticking surface 224a and the upper right sticking surface 224b, a pair of upper and lower positioning projections 421 and 421 projecting outward from the front sticking surface 224a and the upper right sticking surface 224b are extended along the respective upper and lower sides. . The positioning protrusions 421 and 421 have a predetermined height that protrudes outward from the surface 400a of the seal seal 400 in a state where the seal seal 400 is applied to the front application surface 224a and the upper right application surface 224b as described later. The inner surface suspended from the front pasting surface 224a and the upper right pasting surface 224b is a positioning surface 421a of the seal seal 400.

  In addition, triangular positioning corners 422 and 422 projecting inward from each other are formed at the end portions of the positioning projections 421 and 421 on the side wall 202d, and the inner surfaces of these positioning corners 422 and 422 are sealed. The positioning surface 422 a is opposed to the notch side 410 at the corner of the seal 400.

  The end surfaces of the positioning ridges 421 and 421 and the positioning corners 422 and 422 are contact restriction surfaces 423 that contact an inner surface of a seal protection cover 228 described later, and the positioning corners 422 and 422 on the contact restriction surface 423. Engaging convex portions 414 and 414 that are engaged with engaging concave portions 228 a formed in the seal protection cover 228 are respectively provided in the vicinity of.

  In addition, a mounting hole 227 to which the above-described closing screw 226 is attached is formed on the bottom surface at a substantially central position of the cover-side sealing portion 224, and a bottomed cylindrical concave portion 227a that can accommodate the head of the closing screw 226 is formed. (Opening) is formed. An opening 227b (see FIG. 18) on one end side of the recess 227a is formed so as to face the substantially central position of the front sticking surface 224a, and from the opening 227b to the mounting hole 227 and the screw hole 209 of the closing screw 226. Can be installed and removed.

  Thus, the base-side sealing part 229 is composed of the rear sticking surface 229a facing the back side and the lower right sticking surface 229b facing the right side, and the cover side sealing part 224 includes the front sticking surface 224a facing the front side. It is comprised from the upper right sticking surface 224b which faces the right side. As described above, the substrate case 200 includes a base-side sealing portion 229 having a plurality of application surfaces (rear application surface 229a and lower right application surface 229b) facing different directions, and a plurality of application surfaces (front And a cover-side sealing portion 224 having a sticking surface 224a and an upper right sticking surface 224b).

  Next, in order to affix the seal seal 400 to the base side seal portion 229 and the cover side seal portion 224 configured as described above, as shown in FIGS. 17 to 19, the upper region R1 or the lower region of the seal seal 400 is used. A pair of notches 410 and 410 formed at the corners of R3 are arranged so as to be aligned with the pair of positioning surfaces 412a and 412a or the positioning surfaces 422a and 422a.

  By arranging the notch side 410 so as to match the positioning surface 412a in this way, the notch side 410 and the positioning surface 412a are in line contact with each other, so that the sticking position of the seal seal 400 can be determined reliably, and the seal seal 400 Since the positioning surfaces 412a and 412a are erected on the outside of the corners, it is difficult to lift the seal seal 400 from the corners and peel off, so that the seal seal 400 is peeled off and opened illegally. Can be prevented. In addition, since the adjacent pair of positioning surfaces 412a and 412a or the positioning surfaces 422a and 422a are arranged in a letter “C” shape, that is, non-parallel to each other, the pair of notch sides 410 and 410 are paired with the pair of positioning surfaces 412a. , 412a or the positioning surfaces 422a and 422a, the sticking position and sticking direction (orientation) of the seal seal 400 can be easily determined.

  In addition, since the length dimension of the long side portion of the seal seal 400 substantially matches the total length of the long side portions of both the base-side sticking surface and the cover-side sticking surface, If the pasting positions of the cutout sides 410 and 410 in the region R1 or the lower region R3 are determined, all four cutout sides 410 coincide with the positioning surfaces 412a and 422a.

  In this embodiment, the width dimension between the pair of long side portions and the width dimension between the pair of short side portions on the base side sticking surface and the cover side seal sticking surface are the same. If either the width dimension between the pair of long sides or the width dimension between the pair of short sides on the side seal sticking surface is matched, the above-described effect can be obtained.

  Further, in this embodiment, the positioning surfaces 412a and 422a are not only arranged at the corners of the seal seal 400, but also the positioning surfaces 411a and 421a are arranged along the long side portion of the seal seal 400, and the short side Since the side walls of the base member 201 and the cover member 202 function as positioning surfaces along the portion, the application position of the seal seal 400 can be accurately determined. Further, the positioning surfaces 412a, 422a, 411a, 421a and the side wall are provided so as to be suspended from the base side application surface and the cover side application surface and have a length protruding outward from the surface 400a of the seal seal 400. For this reason, it is difficult to insert a cutter or the like between the base side application surface and the cover side application surface and the opposing surface of the seal seal 400. Therefore, after the seal seal 400 is applied once, the seal seal It is extremely difficult to peel the 400 so as not to be damaged.

  The seal protection cover 228 is formed in a U-shape as shown in FIGS. 6 and 17 to 19 so as to sandwich the plate-like sealing portions 224 and 229 protruding outward from the side surface of the substrate case 200 from the front and rear. It is attached to. The front and rear width dimension of the seal protection cover 228 is formed wider than the separation width dimension of the pair of front and rear positioning protrusions 411, 411, 421 and 421, and when the seal protection cover 228 is attached to the sealing portions 224 and 229, The front and rear end edges of the inner surface of 228 are in contact with the contact restriction surfaces 413 and 423 of the positioning protrusions 411, 411, 421 and 421, respectively.

  As described above, the front and rear end edges of the inner surface of the seal protection cover 228 are in contact with the contact restriction surfaces 413 and 423, respectively, so that the opposing surfaces of the surface 400a of the seal seal 400 and the inner surface of the seal protection cover 228 are mutually It is spaced apart and maintained in a non-contact state. That is, since a predetermined gap SP is provided between the opposed surfaces of the surface 400a of the seal seal 400 and the inner surface of the seal protection cover 228, the seal protection cover 228 is left and right while being in contact with the contact restriction surfaces 413 and 423. Even when it is slid to be attached to and detached from the sealing portions 224 and 229, it does not come into contact with the sealing seal 400, and even if any external force is applied to the sealing protective cover 228 in the mounted state, Since there is no direct transmission, the seal seal 400 is prevented from being damaged.

  Further, by fitting the seal protective cover 228 into the sealing portions 224 and 229, the engagement convex portions 414 and 414 are engaged with the engagement concave portions 228a formed on the inner surface of the seal protective cover 228, and thus once mounted. After that, it cannot be removed unless the engagement is released. In this way, it takes time to open the cover member 202 illegally, thereby making it extremely difficult to perform an illegal act.

  Since the outer surface of the seal seal 400 is covered with the seal protection cover 228 in this way, the surface 400a of the seal seal 400 is protected by the seal protection cover 228 in the sealed state, and cannot directly touch the seal seal 400. In addition to preventing fraudulent acts on the seal sticker 400 as much as possible, it is possible to avoid the occurrence of damage due to the application of some external force to the seal sticker 400 when the substrate case 200 is attached to, removed from, or used for the case 1a. it can.

  Further, the seal protection cover 228 is abutted and supported by the abutment restricting surfaces 413 and 423 of the positioning protrusions 411, 411, 421, and 421 protruding from the periphery of the seal seal 400, so that the seal seal 400 and the seal protection are protected. The surface facing the cover 228 can be maintained in a non-contact state, and the external force applied to the seal protection cover 228 is not directly transmitted to the seal seal 400, so that the seal seal 400 can be prevented from being damaged.

  In the first embodiment, the welded portion as an assembling means for assembling the cover member 202 to the base member 201, the base-side sealing portion 229, and the cover-side sealing portion 224 are on the left side of the substrate case 200, that is, described later. The movable base 302 is arranged in parallel on the right side (opposite side) opposite to the left side arranged on the rotating shaft 333 side.

  Further, the cover member 202 has a structure that cannot be detached from the base member 201 unless the cover member 202 is slid in the unlocking direction with respect to the base member 201 from the aligned state. That is, a slide movement guide means is provided that slides and guides in a direction substantially perpendicular to the direction in which the cover member 202 is removed from the base member 201, and is locked in a state in which the slide movement guide means guides the slide movement. Since the cover-side welded portion 223 and the base-side welded portion 207 have a locking action when they are separated from each other toward the opposite sides, the cover-side welded portion 223 and the base-side welded portion 223 It becomes extremely difficult to peel off 207.

  Further, even if two substrate cases of the same type as the substrate case 200 are obtained as in the prior art, both of the base member 201 and the cover member 202 are left scratched when the cover member 202 is opened, and the base is not damaged. Since the member 201 and the cover member 202 cannot be obtained, it is extremely difficult to illegally configure the new substrate case 200.

  As described above, the cover side welding portion 223 and the base side welding portion 207 are welded (fixed) to each other, whereby the sliding movement of the cover member 202 with respect to the base member 201 is restricted. That is, in a state where the locking pieces 203, 203 formed on one short side of the base member 201 are locked to the insertion holes 222, 222 of the cover member 202, the cover side welded portion 223 on the other short side and the base A first sealing state in which the upper surface of the base member 201 is closed by the cover member 202 is configured by the side welded portion 207 being fixed. This first sealed state cannot be released unless both the cover-side welded portion 223 of the cover member 202 and the welded portion of the base-side welded portion 207 of the base member 201 are cut (broken). When it is opened, the trace, that is, the trace that a part of the board case 200 is destroyed, is surely left. As a result, some illegal act is performed on the game control board 40 accommodated in the board case 200. It becomes possible to discover that there is a possibility.

  In this embodiment, when the base member 201 and the cover member 202 are aligned at the closed position, the cover-side welded portion 223 and the base-side welded portion 207 come into contact with each other. As long as it is possible, the cover-side welded portion 223 and the base-side welded portion 207 may be spaced apart from each other.

  Next, as shown in FIG. 5, the case support device 300 includes a fixed base 301 that is attached to the upper part of the inner surface of the back plate 1c of the housing 1a, a locking member 303 that is attached to the right side of the fixed base 301, and a fixed base. A movable base 302 that is rotatably supported by 301 is mainly configured. The movable base 302 has a substrate case 200 attached to the front side, and is supported so as to be rotatable around a rotation axis that faces the fixed base 301 in the vertical direction.

  Then, by attaching the substrate case 200 to the front side of the movable base 302, the substrate case 200 is arranged in a first rotation restricting position A (see FIG. 4) where the back surface 40b side of the game control substrate 40 is disposed opposite to the back plate 1c and cannot be seen. 14 (a)) and the second rotation restricting position B (see FIG. 14 (b)) at which the back surface 40b side of the game control board 40 can be visually recognized. Since the board case 200 is attached to the back plate 1c, the mounting surface 40a and the back surface 40b of the game control board 40 accommodated in the board case 200 are moved to the transparent board case 200 and movable. It can be visually recognized through the base 302.

  As shown in FIGS. 11 to 14, the movable base 302 is made of a transparent thermoplastic synthetic resin, has a substantially rectangular bottom plate 310 a, and is erected forward on the upper and lower long sides of the bottom plate 310 a. A pair of side walls 310b and 310b are respectively extended in the longitudinal direction, and short side walls 310c and 310c are continuously provided from both ends of the left short side portion in the longitudinal direction from the ends of the side walls 310b and 310b, and on the right short side portion. The side wall 310d of the short side extends in the longitudinal direction.

  An elastic locking claw 311 capable of locking a predetermined portion of the cover member 202 in the substrate case 200 attached to the front surface side of the bottom plate 310a is formed inward at the right end portion of the upper side wall 310b. 200 can be locked.

  A board-side connector 620c (see FIG. 4) of the game control board 40, a cable-side connector 610c connected to the board-side connector 620c, and a protective member 660 that protects the cable 600c are attached to the left end of the lower side wall 310b. A mounting slit 312 is formed. The attachment slit 312 is formed by bulging a part of the side wall 310b, and can be inserted through the attachment piece 660a of the protection member 660. Further, a locking hole 312a is formed on the outer surface of the mounting slit 312 so that the outward elastic locking claw 660b formed in the mounting piece 660a is locked. It can be regulated.

  In this way, the attachment piece 660a is inserted into the attachment slit 312 and the elastic engagement claw 660b is engaged with the engagement hole 312a, so that the guard piece 660c and the guard side piece formed to be bent with respect to the attachment piece 660a. The periphery of the board-side connector 620c, the cable-side connector 610c connected to the board-side connector 620c, and the cable 600c is covered and protected by 660d.

  In the vicinity of the short side portion on the right side of the bottom plate 310a, mounting holes 316a and 316b to which the one-way screws 240a and 240b inserted into the mounting sealing piece 230 and the spare mounting sealing piece 231 of the substrate case 200 are attached are formed. A base mounting hole 317 for mounting the mounting base 315 is formed. The mounting base 315 is mounted by fitting into the base mounting hole 317 from the back side of the bottom plate 310a. At the time of mounting, as shown in FIG. 13A, the mounting holes 316a and 316b protrude forward from the front surface of the bottom plate 310a, and the mounting holes 235 of the mounting sealing piece 230 and the spare mounting sealing piece 231 are provided. , 235 are arranged opposite to each other.

  As described above, the mounting base 315 is detachably attached to the movable base 302, so that, for example, the mounting sealing piece 230 and the spare mounting sealing piece 231 are cut from the substrate case 200 as described later. When the movable base 302 is left behind, only the mounting base 315 can be replaced with a new one.

  Locking pins 303a and 303a (see FIG. 5) of a locking member 303 for locking the free end of the movable base 302 to the front side of the back plate 1c are provided on the short side on the right side of the movable base 302. Insertable insertion holes 318 and 318 are formed, and in the vicinity of the respective insertion holes 318 and 318, locking hooks 319 and 319 that can be locked to the tips of the locking pins 303a and 303a are provided in the front-rear direction. It is attached so that it can turn around the axis.

  From both sides in the longitudinal direction of the short side on the left side of the movable base 302, a plate-like shape in which a shaft support groove 320 having a substantially U shape for receiving a rotation shaft 333 formed on the fixed base 301 described later is formed. The shaft support plates 321 and 321 are projected outward in a direction orthogonal to the short side portion. The shaft support groove 320 extends rearward from the front end sides of the shaft support plates 321 and 321, and the rotation shaft 333 can be attached to and removed from the opening portion on the front side.

  A covering portion 322 that covers a base mounting screw 335 for mounting a fixed base 301 (to be described later) to the back plate 1c is formed at the central position in the longitudinal direction of the short side portion on the left side of the movable base 302. The covering portion 322 is parallel to the vertical piece 322b erected vertically from the short side of the bottom plate 310a toward the front, and the bottom plate 310a bent outward from the tip of the vertical piece 322b. The bent piece 322a is formed of side pieces 322c and 322c that cover the sides of the bent piece 322a and the vertical piece 322b, and an outer piece 322d that is inclined outward from the tip of the bent piece 322a. In addition, the bent piece 322a has a length that can cover the base mounting screw 335 (see FIG. 13) directly in a state where the pivot support groove 320 is pivotally supported on the rotation shaft 333 of the fixed base 301.

  The upper and lower side pieces 322c and the shaft support plate 321 are arranged with a predetermined distance therebetween, and an insertion portion through which the plate-like piece 221 of the cover member 202 can be inserted between the side pieces 322c and the shaft support plate 321. 324 and 324 are formed. Since the insertion portions 324 and 324 are formed to have a vertical width slightly longer than the vertical width of the plate-like pieces 221, 221, the substrate case 200 is attached to the front side of the movable base 302 as will be described later. In this state, the upper and lower side portions of the plate-like pieces 221 and 221 inserted through the insertion portions 324 and 324 are guided by the side piece 322c and the shaft support plate 321. Further, the vertical piece 322b contacts the side wall 202c of the cover member 202 and determines the position of the substrate case 200 in the left-right direction with respect to the movable base 302.

  At the distal end portions of the insertion portions 324 and 324, band plate-like locking plates 323 and 323 that lock the front side of the distal end portions of the plate-like pieces 221 and 221 inserted through the insertion portions 324 and 324 are pivotally supported. It is constructed between the plate 321 and the side piece 322c. That is, the upper and lower shaft support plates 321 and the side pieces 322c are connected by the locking plates 323 and 323, respectively. Further, since the locking plates 323 and 323 are disposed outside the shaft support grooves 320 and 320, they do not interfere when the rotating shafts 333 and 333 are attached to and detached from the shaft support grooves 320 and 320.

  As shown in FIG. 5, the fixed base 301 is attached to the inner surface of the back plate 1c and is attached to the inner surface of the back plate 1c in the vertical direction, and the upper and lower portions are bent forward from the upper and lower ends of the attachment piece 330a. A main body portion made of a plate-shaped metal material composed of a pair of shaft pieces 330b, 330b and a protective piece 330c bent forward from the left side of the mounting piece 330a, and each of the shaft pieces 330b, 330b From the opposing surfaces, cylindrical pivot shafts 333 and 333 facing upward and downward are respectively provided inwardly projecting so that the respective axes P1 (see FIG. 13B) are located on the same line. It is configured.

  The pair of upper and lower rotating shafts 333 and 333 are arranged in parallel to the mounting piece 330a at a position in front of the mounting piece 330a so that the tip portions thereof are separated from each other by a predetermined distance. The base mounting screw 335 is a so-called general screw that can be attached and detached by rotating the forward and reverse directions by fitting the tip of the driver into the screw groove. The fixed base 301 configured as described above is attached to the inner surface of the back plate 1c by a base mounting screw 335. The cover member 336 is formed so as to accommodate the head of the base mounting screw 335.

  When the movable base 302 is attached to the fixed base 301, the left and right end portions of the movable base 302 are oriented in the longitudinal direction so as to be orthogonal to the back plate 1c with the front and rear direction directed. As a result, since the open portions of the shaft support grooves 320 and 320 face the rotation shafts 333 and 333, the movable base 302 is brought close to the fixed base 301 in this posture, and the shaft support grooves 320 and 320 are moved to the rotation shaft 333. After being inserted into 333, the front side of the movable base 302 is pushed toward the back plate 1 c around the rotation shafts 333 and 333.

  When the movable base 302 is disposed in the lateral orientation in which the rear surface faces the inner surface of the back plate 1 c, that is, in the first rotation restricting position A, the locking pins 303 a and 303 a of the locking member 303 are arranged on the movable base 302. The locking hooks 319 and 319 are rotated and engaged with the tips of the locking pins 303a and 303a that are inserted into the insertion holes 318 and 318 and the tips of the locking pins 303a and 303a protrude forward from the insertion holes 318 and 318, respectively. Stop. Accordingly, the left end portion of the movable base 302 is pivotally supported by the rotation shafts 333 and 333, and the right end portion is locked by the locking pins 303a and 303a, whereby the movable base 302 is detached from the back plate 1c. And the rotation around the rotation shafts 333 and 333 is restricted, and is temporarily fixed at a first rotation restriction position A substantially parallel to the back plate 1c.

  In this way, when the pivot bases 320 and 320 of the movable base 302 are pivotally supported on the pivot shafts 333 and 333 of the fixed base 301 and the movable base 302 is disposed at the first rotation restriction position A, the pivot support grooves 320 and 320 are arranged. 320 is open frontward in the front-rear direction, but when the back plate 1c is close to the rear surface of the movable base 302, the rearward movement of the shaft support grooves 320, 320 with respect to the rotating shafts 333, 333 is restricted. Therefore, the shaft support grooves 320 and 320 are not detached from the rotation shafts 333 and 333.

  Further, as shown in FIG. 13, the front side of the base mounting screw 335 for attaching the fixed base 301 to the back plate 1c is covered with the covering portion 322 of the movable base 302, and the left outer side is covered with the protective piece 330c. Even if a driver or a finger is brought into contact with the base mounting screw 335, not only is the contact difficult, but the driver cannot be placed on an extension line of the axis P2 of the base mounting screw 335.

  Next, in order to attach the substrate case 200 in the sealed state as described above to the movable base 302 temporarily fixed at the first rotation restricting position A, as shown in FIG. A pair of plate-like pieces 221, 221 provided on the left short side of the cover member 202 are slid to the left side with the side facing the front surface of the movable base 302, and the rotation shafts 333, 333 After being inserted into a gap formed between the locking plates 323 and 323 (see FIG. 13A), the right short side of the substrate case 200 is pushed toward the movable base 302.

  At this time, the tips of the plate-like pieces 221 and 221 are locked to the locking plates 323 and 323 (see FIG. 13B), and the upper side of the cover member 202 on the right end side is the elastic locking of the movable base 302. Locked to the claw 311. The substrate case 200 is covered with the side walls 310b, 310c, and 310d of the movable base 302, so that the sliding movement of the movable base 302 on the bottom plate 310a is restricted, so that the separation from the movable base 302 is restricted. . However, in this temporarily fixed state, the substrate case 200 can be easily removed from the movable base 302 by releasing the locked state of the cover member 202 by the elastic locking claw 311.

  Further, in the temporarily fixed state, the mounting sealing piece 230 and the spare mounting sealing piece 231 in the cover member 202 are arranged to face the mounting base 315, and the mounting sealing piece 230 and the spare mounting sealing piece 231 are arranged. The mounting holes 235 and 235 coincide with the mounting holes 316 a and 316 b of the mounting base 315. Here, as shown in FIG. 13A, when the one-way screw 240a accommodated in the mounting sealing piece 230 is screwed into the screw hole 316a by a screwdriver, the substrate case 200 cannot be detached from the movable base 302. Attached to.

  That is, once the one-way screw 240a is attached to the screw hole 316a, even if a tool such as a screwdriver is inserted into the operation groove, the one-way screw 240a cannot be reversely rotated, that is, cannot be removed from the screw hole 316a again. Therefore, the substrate case 200 is attached so that it cannot be removed from the movable base 302 unless a predetermined portion (for example, the cut piece 233 of the attachment sealing piece 230) of the substrate case 200 or the movable base 302 is cut (destroyed). Installed in a state.

  When removing the board case 200 from the movable base 302 for inspection of the game control board 40, it is necessary not only to cut the cutting piece 233 of the mounting sealing piece 230 but also a one-way screw screwed into the screw hole 316a. 240a and the mounting sealing piece 230 cut from the substrate case 200 cannot be removed from the mounting base 315 and remain held by the movable base 302. Therefore, the one-way screw 240a is attached to the mounting sealing piece 230, and the same Thus, it cannot be attached to the movable base 302. That is, once the mounting state of the substrate case 200 with respect to the movable base 302 is released, a spare one-way screw 240b is attached to a spare mounting sealing piece 231 different from the mounting sealing piece 230 used for once mounting. It attaches to the screw hole 316b.

  In this attached state, as shown in FIG. 13B, the plate-like pieces 221 and 221 are inserted into the gaps formed between the rotating shafts 333 and 333 and the locking plates 323 and 323. Thus, the detachment of the rotation shafts 333 and 333 from the shaft support grooves 320 and 320 is restricted by the plate-like pieces 221 and 221 of the substrate case 200 attached to the movable base 302. As a result, the pivotal support state of the movable base 302 with respect to the fixed base 301 cannot be released.

  Unless the substrate case 200 is removed from the movable base 302, the plate-like pieces 221 and 221 inserted into the gap formed between the rotating shafts 333 and 333 and the locking plates 323 and 323 are taken out from the gap. In other words, since it is not possible to release the restriction of detachment of the shaft support grooves 320, 320 from the rotation shafts 333, 333, not only the substrate case 200 is removed from the movable base 302 but also the movable base 302 is removed from the fixed base 301. It cannot be removed.

  Further, the rotation shafts 333 and 333 are covered with plate-like pieces 221 and 221 inserted into gaps formed between the rotation shafts 333 and 333 and the locking plates 323 and 323. Specifically, the locking plates 323 and 323 have a slightly smaller width than the separation width between the shaft support plate 321 and the side piece 322c, so that the rotation shafts 333 and 333 and the locking plate 323 are arranged. , 323, the movable base 302 is separated from the fixed base 301 by cutting the rotary shafts 333 and 333 in order to cover the longitudinal directions of the rotary shafts 333 and 333. Unauthorized actions such as removal are prevented.

  As shown in FIG. 14, the board case 200 attached to the case support device 300 attached to the back plate 1c in this way has the electronic component mounting surface 40a of the game control board 40 facing the front side and the back side 40b side. A first rotation restricting position A that faces the inner surface of the back plate 1c and becomes invisible from the front side of the housing 1a, and the mounting surface 40a faces the inner surface of the left side plate of the housing 1a and the game control board 40 The back surface 40b side is supported so as to be rotatable within a rotatable range (about 83 degrees) between the second rotation restricting position B that is visible from the front side of the housing 1a.

  Accordingly, as shown in FIG. 14A, when the board case 200 is positioned at the first rotation restricting position A, the mounting surface 40a of the game control board 40 faces the front side, so the board case 200 Even if the mounting surface 40a is not removed from the movable base 302, the mounting surface 40a can be viewed through the transparent cover member 202 from the front side of the housing 1a.

  Further, as shown in FIG. 14B, when the substrate case 200 is positioned in the vicinity of the second rotation restricting position B, the back surface 40b of the game control substrate 40 is separated from the back plate 1c and the right side is moved. Therefore, even if the substrate case 200 is not removed from the movable base 302, the back surface 40b can be viewed through the transparent base member 201 and the transparent movable base 302 from the front side of the housing 1a. Therefore, even when the board case 200 is attached to the housing 1a, there is a trace that the mounting surface 40a and the back surface 40b of the game control board 40 accommodated therein are tampered with by simply rotating the board case 200. It can be easily confirmed visually whether or not there is.

  Further, as shown in FIG. 14A, the substrate case 200 is normally disposed at the first rotation restricting position A. In this state, cable-side connectors of various cables are connected to the board-side connectors arranged so as to face the connector openings 236a to 236g formed in the cover member 202.

  Of the connector openings 236a to 236g formed in the cover member 202, the connector openings 236d to 236c that the board side connectors 620a to 620c face are as shown in FIG. Is also provided on the left region, that is, on the side where the rotation shafts 333 and 333 are disposed. Of the board-side connectors 620a to 620c facing the connector openings 236a to 236c, the connection part between the cable-side connector 610c and the board-side connector 620c, one end of which is connected to the power supply board 101, is covered by the protective member 660 described above. In addition, the connection portion between the cable-side connector 610b and the board-side connector 620b, one end of which is connected to the start switch 7, is covered by the connector restricting member 650 described above, and in particular, the cable-side connector 610b covered by the connector restricting member 650. Is restricted from being removed from the board-side connector 620b.

  Thus, the cables 600a to 600c connected to the board-side connectors 620a to 620c provided in the region on the left side of the center position in the left-right direction of the cover member 202 are wired together on the inner surface of the left side plate. The cable-side connectors 610a to 610c provided on the cables 600a to 600c can rotate the substrate case 200 to the second rotation restriction position B without being removed from the substrate-side connectors 620a to 620c. It has become. Further, if the cable-side connector connected to the board-side connector provided in the region on the right side of the center position in the left-right direction of the cover member 202 is not removed from the board-side connector, the board case 200 is controlled to the second rotation restriction. It can be rotated to position B.

  In other words, the board-side connectors 620a to 620c arranged in the left region near the rotation shaft 333 have a movement distance when the substrate case 200 is rotated around the rotation shaft 333 so that the movement distance is far from the rotation shaft 333. Therefore, the surplus length of the connected cables 600a to 600c is shorter than that of the cable connected to the board-side connector arranged in the right region far from the rotation shaft 333. I'll do it.

  Therefore, if the board-side connectors 620a to 620c and the like that are covered by the protective member 660 and the connector restricting member 650 and are troublesome to remove are arranged in the left region near the rotation shaft 333, the board case 200 is rotated. Since it is not necessary to sequentially remove the cable-side connectors 610a to 610c from the board-side connectors 620a to 620c each time it is moved, the check operation of the game control board 40 is not complicated and the cables are connected to the board-side connectors 620a to 620a. When the substrate case 200 can be rotated without being removed from the 620c, the cables 600a to 600c can be shortened as much as possible.

  In the present embodiment, the substrate case 200 is attached to the upper portion of the back plate of the housing 1a as shown in FIG. The connector openings 236a to 236g facing the board side connectors 620a to 620c to which the various cables 600a to 600c and 600k are connected are arranged along the lower side of the board case 200. Of these cables 600a to 600c and 600k connected to the game control board 40, the cables 600a to 600c are provided on the inner surface of the left side plate of the housing 1a at a position below the board case 200 as shown in FIG. The wiring hooks HF are wired together. The other cable 600k extends downward and is connected to a reel relay board 120 and the like disposed below the board case 200 in the housing 1a.

  That is, the cables 600a to 600c and 600k having one end connected to the game control board 40 are held (connected) by the wiring holding parts such as the wiring hook HF and the reel relay board 120 disposed below the board case 200. Therefore, the seal seal 400 that is affixed to the position higher than the connector openings 236a to 236g in the board case 200 does not overlap with the cables 600a to 600c, 600k, and the like so that the seal seal 400 is not hidden. ing. Therefore, in the seal seal 400, the solvent use display portions 450A to 450D are arranged in portions that do not overlap with the wirings such as the cables 600a to 600c and 600k when the seal seal 400 is attached to the substrate case 200.

  In other words, when the seal sticker 400 is affixed to the board case 200, the seal sticker 400 does not overlap with a straight line connecting the board-side connector of the game control board 40 and the wiring holding part such as the wiring hook HF or the reel relay board 120 or the like. Since it is arrange | positioned in the vicinity position, it is prevented that the solvent use display part 450A-450D is hidden by wiring, and the visibility of the solvent use display part 450A-450D is impaired.

  As described above, in the slot machine 1 as the first embodiment of the present invention, as shown in FIG. 15, the solvent use display portion 450 </ b> A and the first identification information display portion 451 are provided on the surface of the seal base 401. The upper region R1 provided with the second identification information display part 452 and the hologram display part 453A is located on the front sticking surface 224a of the cover side sealing part 224, and is provided with a solvent use display part 450B and a solvent use display part 450C. The intermediate region R2 is located on the upper right sticking surface 224b and the lower right sticking surface 229b, and the lower region R3 provided with the solvent use display portion 450D and the hologram display portion 453B is on the rear sticking surface 229a of the base side sealing portion 229. To position.

  The seal sticker 400 is not positioned at the boundary portion Z between the cover member 202 and the base member 201 when the seal sticker 400 is applied so as to straddle the base side seal part 229 and the cover side seal part 224 in the substrate case 200. Since the solvent use display portions 450A to 450D are printed and formed on the portions, the solvent use display portions 450A to 450D do not hang on the boundary Z when the sealing state is set. Since the seal seal 400 was broken for the inspection of the substrate 40 and the substrate case 200 was opened, the solvent use display portions 450A to 450D were broken, and traces of contact with the solvent appeared before that. Is prevented from becoming difficult to understand.

  Specifically, the substrate case 200 of the present embodiment can be opened by sliding the cover member 202 with respect to the base member 201, so that the sealing seal 400 is attached to the base side sealing portion 229 and the cover side of the substrate case 200. When the substrate case 200 is opened in the second sealing state pasted so as to straddle the sealing portion 224, the portion corresponding to the boundary portion Z in the sealing seal 400 is easily broken. Therefore, in the seal sticker 400, when any of the solvent use display parts 450A to 450D is printed on the part corresponding to (corresponding to) the boundary part Z when the base side seal part 229 and the cover side seal part 224 are attached. Even if the solvent use display portions 450A to 450D are dissolved by use of the solvent, for example, by opening the substrate case 200 for inspection of the game control substrate 40 in a game store, the boundary portion Z of the seal seal 400 Will break, and it will be difficult to determine if the solvent usage indicator has disappeared and is no longer visible, or if it has become invisible due to fracture, so it will be difficult to understand that traces of contact with the solvent have appeared. . Therefore, the solvent use display portions 450A to 450D are printed and formed on the portion not located at the boundary Z between the cover member 202 and the base member 201 when pasted so as to straddle the base side sealing portion 229 and the cover side sealing portion 224. Has been.

  The seal seal 400 has the same direction as the mounting surface 40a on which the control microcomputer (the microcomputer including the CPU 41a, the ROM 41b, the RAM 41c, and the I / O port 41d) is mounted on the game control board 40 which is an example of a circuit board. Since the solvent use display portion 450A is arranged in the upper region R1 that is a portion facing (upward), both the solvent use display portion 450A and the mounting surface 40a of the control microcomputer can be viewed together ( 14 (a)), it is possible to easily confirm the illegal act on the solvent use display unit 450A and the control microcomputer (the microcomputer including the CPU 41a, the ROM 41b, the RAM 41c, and the I / O port 41d). Therefore, the work load can be reduced.

  It should be noted that the act of confirming fraud against the control microcomputer (the microcomputer having the CPU 41a, ROM 41b, RAM 41c, and I / O port 41d) is, for example, an illegal circuit in the CPU 41a, ROM 41b, RAM 41c, and I / O port 41d Since it is an operation to confirm whether the board is connected or the CPU 41a, ROM 41b, etc. are replaced with an unauthorized CPU, ROM, etc., the mounting surface 40a on which these are mounted and the solvent use indicator 450A are provided. If they are arranged upward, it is possible to confirm both situations at the same time from the front side of the substrate case 200.

  In addition, the seal sticker 400 is attached to the substrate case 200 in the upper region R1, which is a portion facing in the same direction (upward), and a solvent use display portion 450A and a first identification information display portion 451 as an identification information display portion. Since the second identification information display unit 452 is disposed, both the solvent use display unit 450A, the first identification information display unit 451, and the second identification information display unit 452 can be viewed together. Since it is possible to easily check the solvent use display unit 450A, the first identification information display unit 451, and the second identification information display unit 452, the work load can be reduced.

  Further, in this embodiment, the seal seal 400 includes an upper region R1 in which the solvent use display unit 450A, the first identification information display unit 451, and the second identification information display unit 452 are directed in the same direction (upward). By being arranged in the above, the control microcomputer (the CPU 41a, the ROM 41b, the RAM 41c, the microcomputer including the I / O port 41d) is mounted in the same direction (upward) as the mounting surface 40a. In addition to the confirmation work of the solvent use display section 450A, the first identification information display section 451, and the second identification information display section 452, it is possible to easily perform a fraud confirmation work for the control microcomputer. Work load can be reduced.

  Further, in this embodiment, the solvent use display portion and the identification information display portion are printed in the upper region R1 which is a portion facing upward when being attached to the substrate case 200 in the seal sticker 400. It may be printed in the region R2 or the lower region R3.

  In the present embodiment, the solvent use display portion 450A and the first identification information display portion 451 and the second identification information display portion 452 as the identification information display portion are arranged in the upper region R1, but the identification information display portion As long as at least one of the first identification information display unit 451 and the second identification information display unit 452 is disposed. Other identification information may also be arranged.

  In addition, when pasted across a plurality of pasting surfaces (rear pasting surface 229a, lower right pasting surface 229b, front pasting surface 224a, upper right pasting surface 224b), between one pasting surface and the other pasting surface The formed corner, specifically, the corner C1 (see FIG. 16) formed between the rear application surface 229a and the lower right application surface 229b, or between the front application surface 224a and the upper right application surface 224b. When the solvent use display portions 450A to 450D are arranged in a portion not positioned at the corner portion C2 (see FIG. 16) formed in the substrate (see FIG. 15A), the solvent is used when the substrate case 200 is pasted. Since the use display portions 450A to 450D do not hang over the corner portions C1 and C2, it is possible to prevent the visibility from being impaired by bending the characters of the solvent use display portions 450A to 450D.

  In this embodiment, the corners C1 and C2 are corners having a bending angle of about 90 degrees, but may be obtuse corners of 90 degrees or more or acute corners of less than 90 degrees. In this embodiment, when the substrate case 200 is attached to the movable base 302, the corner portion C1 is disposed close to the movable base 302, whereas the corner portion C2 is exposed to the front surface side. It is preferable that the solvent use display portions 450A to 450D are arranged at portions not located at the corner portion C2.

  That is, a part of one solvent use indicator is arranged on one affixing surface, and another part is arranged on another affixing surface whose direction is different from that of one affixing surface, so that one solvent use indicator is What is necessary is just not to bend by the corner | angular part formed between one sticking surface and another sticking surface.

  Further, by further including a seal protection cover 228 as a seal seal covering member capable of covering the seal seal 400 affixed to the substrate case 200, the seal seal 400 is covered with the seal protection cover 228, so that the seal seal 400 is covered. In order to peel off, the seal protection cover 228 must be removed, and it takes time and effort, so that illegal actions can be suppressed.

  In this embodiment, since the seal protection cover 228 is made of a transparent synthetic resin material, even when it is covered with the seal protection cover 228, the seal protection cover 228 can be used through the seal protection cover 228. Since it can be confirmed whether the display portions 450A to 450D have disappeared or become thin, it can be easily confirmed.

  Further, as shown in FIG. 14, the seal seal 400 includes cables 600 a to 600 c and 600 k (wiring) connected to the game control board 40 housed in the board case 200 when attached to the board case 200. Since the solvent use display portions 450A to 450D are arranged in the non-overlapping portions, the solvent use display portions 450A to 450D are not hidden by the cables 600a to 600c and 600k. Visibility is prevented from being impaired.

  In the present embodiment, when the substrate case 200 is attached to the housing 1a, the seal seal 400 is disposed at a position higher than the cables 600a to 600c and 600k, so that the solvent use display portions 450A to 450D are displayed. The cables 600a to 600c and 600k (wiring) do not overlap with each other. However, even when one end of these wirings is held at a position above the seal seal 400, the first holding portion that holds the wiring and the cable It is only necessary that the solvent use display portions 450A to 450D of the seal seal 400 be disposed at a position that does not overlap on a straight line connecting the second holding portion different from the first holding portion or a position in the vicinity thereof.

  The first holding part for holding the wiring and the second holding part different from the first holding part may be a connector for connecting one end or the other end of the wiring, or one end and the other end of the wiring. It may be a wiring hook or the like that holds a place other than the above.

  Further, in the first embodiment, the seal seal 400 is provided at a predetermined portion of the seal seal 400 by providing a corner-side cut 408 as a weakened portion whose strength is lower than that of other portions. Since the corner-side cut 408 is easily broken at the time of peeling, it is possible to suppress an illegal act such as reattaching the seal seal 400 peeled by the solvent.

  In the first embodiment, the seal seal 400 includes a first identification information display unit 451 in which a serial number or the like, which is identification information that can identify each seal seal 400, is displayed so as to be visually readable. A second identification information display unit 452 that can be read by a predetermined reading device (not shown) by encoding a two-dimensional barcode or the like that is identification information that can identify the seal seal 400; Separately from the first identification information display unit 451, the second identification information display unit 452 that can be read only by a predetermined reader is provided, so that the identification information is read from the second identification information display unit 452. Is difficult, and it takes time to forge the seal seal 400, so that the security is improved.

  Further, in the first embodiment, the protruding strips 411 and 421 which are peripheral wall portions are provided around the sealing portion including the base side sealing portion 229 and the cover side sealing portion 224 so as to surround the periphery of the pasted sealing seal 400. By being formed, when the seal seal 400 is peeled off, the surrounding ridges 411 and 421 become obstructive and difficult to peel off, so that it is possible to suppress an illegal act such as reattaching the seal seal 400 peeled by the solvent. .

  In addition, in the present Example 1, the peripheral wall part was formed by the protruding item | line, However, A peripheral wall part may be formed in the surrounding surface of this recessed part by making the recessed part formed in the plane into a sealing seal sticking part. .

  In the first embodiment, the seal seal 400 does not include an electronic tag that can read identification information (for example, a serial number) that can identify each seal seal by a predetermined electromagnetic wave. An electronic tag may be provided by being embedded in, for example, the pressure-sensitive adhesive layer 402 of the seal seal 400. In this way, management of the identification information becomes easy, and since it is necessary to use a predetermined electromagnetic wave to read the identification information, it becomes time-consuming to forge the seal seal. Will improve.

  Further, even when the substrate case 200 is attached to the housing 1a, the front and back sides of the game control board 40 can be visually recognized by rotating the movable base 302 with respect to the fixed base 301. Since both the welded portion and the sealing portion including the sealing seal 400 are arranged on the right side opposite to the rotating shaft 333, whether or not the cover member 202 has been opened, that is, the game control board 40 is illegally modified. It is possible to easily confirm whether or not it has been applied. In addition, in the assembled state, when the cover member 202 is opened, the trace remains, and therefore it is possible that an illegal act such as switching to the board case 200 containing the illegal game control board 40 may be performed. You can discover that there is sex.

  In the first embodiment, the welding portion is applied as an assembling means for assembling the cover member 202 to the base member 201. However, the present invention is not limited to such a welding means. For example, a one-way screw, a latch, or the like is used. A means for assembling with an assembling member may be used.

  In the first embodiment, the welded portion and the sealing portion are provided on one short side portion of the substrate case 200. However, when the rotating shaft 333 is disposed on one long side portion side, What is necessary is just to provide a welding part and a sealing part in the long side part side.

  Even when the board case 200 is attached to the back plate 1c, the back surface 40b side of the game control board 40 is visually recognized by rotating the board case 200 from the first rotation restriction position A to the second rotation restriction position B. Therefore, it is possible to easily check whether or not the game control board 40 has been illegally modified. Further, when the movable base 302 is detached from the fixed base 301 or the substrate case 200 is detached from the movable base 302 in the assembled state in which the substrate case 200 is attached to the movable base 302, a cut piece 233 or a plate-like shape is obtained. Not only the traces are left by cutting the piece 221 and the like, but also when the base mounting screw 335 is removed and the fixed base 301 is removed from the back plate 1c, that is, the board case 200 is cut to be removed from the movable base 302. Since the trace remains even when the piece 233 is cut or the covering portion 322 or the cover member 336 of the movable base 302 is destroyed, the board case 200 is removed from the back plate 1c, and the board containing the illegal game control board 40 Found that there was a possibility of fraudulent actions such as turning back to Case 200 Rukoto can.

  In other words, the attachment of the substrate case 200 to the movable base 302, the attachment of the fixed base 301 to the movable base 302, and the attachment of the fixed base 301 to the back plate 1c destroy the attachment-related parts related to those attachments (cutting or If it is performed by the attachment means that cannot release each attachment state unless it includes (such as peeling), the trace remains reliably when each attachment state is released, and this causes illegal acts. It can be surely discovered that there was a possibility.

  In particular, in this embodiment, the front door 1b is pivotally supported on the left side of the housing 1a so that the substrate case 200 is also the same as the front door 1b when the front door 1b is opened. Since it rotates about the left side, when the back surface 40b of the substrate case 200 is visually recognized, the back surface 40b opens to the right without the front door 1b, and therefore the front door 1b becomes an obstacle when checking. There is no.

  Further, since the movable base 302 is configured to be attached to and detached from the fixed base 301 from a predetermined attaching / detaching position, the fixed base 301 can be easily attached and detached with the base attaching screw 335, and one-way. By attaching the substrate case 200 to the movable base 302 with the screws 240a, the plate-like piece 221 provided on the attached substrate case 200 regulates the detachment of the rotating shaft 333 from the shaft support groove 320, thereby fixing the fixed base. Since the covering portion 322 provided on the movable base 302 that can no longer be detached from the 301 cannot always release the mounting state by the base mounting screw 335 within the rotatable range, the fixed base 301 and the like are destroyed. Even if it is necessary to replace It is not necessary to or removed from a like back plate 1c of the fixed base 301 to destroy, it is possible to reuse a housing 1a.

  In addition, since the movable base 302 can be attached to and detached from the fixed base 301 unless the substrate case 200 is attached, a predetermined part is damaged or destroyed due to, for example, a turning operation or an illegal act. When the shaft support groove 320 is worn due to friction with the rotation shaft 333 or the like, it is possible to easily remove it from the fixed base 301.

  Further, since the detachment of the movable base 302 from the fixed base 301 can be regulated by using the attachment of the substrate case 200 to the movable base 302 by the one-way screw 240a, the movable base 302 can be simply removed from the movable base 302. In addition to the one-way screw 240a for attaching the substrate case 200 to the movable base 302, a means for regulating the separation of the rotating shaft 333 from the shaft support groove 320 can be removed. Therefore, not only can the structure of the case support device 300 be simplified, but also the work load can be reduced.

  In addition, since the substrate case 200 is attached to the movable base 302 with the one-way screw 240a that cannot be removed once attached to the attachment base 315, the cutting piece 233 is cut to attach the attachment sealing piece 230 to the substrate case 200. The substrate case 200 cannot be removed from the movable base 302 unless it is separated from the main body or the mounting base 315 or the like that is a part of the movable base 302 is destroyed. When the substrate case 200 is detached from the movable base 302 by separating the stop piece 230 from the main body of the substrate case 200, the attachment sealing piece 230 separated from the substrate case 200 is attached to the attachment base 315 together with the one-way screw 240a. The mounting sealing piece 230 is not a single member, but a movable base. Since remaining mounting base 315 of 302, it can be discarded along with the mounting base 315.

  In this embodiment, the mounting base 315 having mounting holes 316a and 316b as mounting portions of the movable base 302 to which the mounting sealing piece 230 as the mounting portion of the substrate case 200 and the auxiliary mounting sealing piece 231 are mounted. Is provided so that it can be attached to and detached from the movable base 302, so that even when the substrate case 200 is removed twice, if only the mounting base 315 is replaced, the movable base 302 can be used without replacement. However, the mounting holes 316a and 316b may be directly formed in the movable base 302.

  In this embodiment, the substrate case 200 is attached to the movable base 302 with the one-way screws 240a and 240b. However, the attachment member such as a locking pin or the attachment member such as an adhesive, You may make it attach via the attachment member which cannot be removed once attached. Further, a locking pin or the like for attaching the substrate case 200 to the movable base 302 may be formed integrally with the substrate case 200 or the movable base 302 in advance.

  In this embodiment, the cover member 202 and the base member 201 are sealed by heat welding and sealing. However, a fixing member such as a one-way screw or a locking pin, or a fixing member such as an adhesive. You may make it fix through.

  In the present embodiment, the substrate case 200 is rotatably supported on the inner surface of the back plate 1c of the housing 1a via the case support device 300. However, the substrate case 200 is limited to those attached to the back plate 1c. It may be attached to the inner surfaces of the left and right side plates of the housing 1a, or may be attached to the rear surface of the front door 1b. Furthermore, you may attach to the attachment member etc. which are provided in these housing | casing 1a or the front door 1b.

  In the present embodiment, the board case 200 is capable of opening and closing the base member 201 that can cover the back surface 40b side of the game control board 40 as a circuit board, and the opening of the base member 201. The cover member 202 is configured to cover the mounting surface 40a side, but may be configured from a case body and a cover body that coverably cover the front and back surfaces of the game control board 40. The case body only needs to be provided with both a first see-through portion that can see through the mounting surface 40a and a second see-through portion that can see through the back surface 40b.

  Further, in the present embodiment, an assembling means including a welded portion made up of the cover-side welded portion 223 and the base-side welded portion 207, an attached sealing portion made up of the attached sealing piece 230 and the one-way screw 240a, and a base-side sealed portion 229 and the sealing part consisting of the cover side sealing part 224 are arranged in parallel on the right side opposite to the left side arranged on the rotating shaft 333 (shaft part) side of the case support device 300 in the substrate case 200. Therefore, in a state where the substrate case 200 is attached to the movable base 302, the movable base 302 is rotated to the second rotation restricting position B, so that the sealing state and the sealing seal by the welding and assembly means such as the one-way screw 240a are provided. Since both of the sealing states of the sealing portion by 400 can be observed at a time, whether or not there is a trace that the sealing state is released and the cover member 202 is opened, that is, the game control board 40 is illegally modified. It is possible to easily confirm whether or not it has been done.

  In the present embodiment, the mounting surface 40a and the back surface 40b of the game control board 40 can be selectively visually recognized from the front side of the housing 1a inside the housing 1a of the slot machine 1 which is an example of the gaming machine. As described above, the movable base 302 is rotatably supported via the case support device 300. For example, when the substrate case 200 is rotatably supported by the pachinko gaming machine via the case support device 300, the pachinko game When the machine is opened, the mounting surface 40a and the back surface 40b of the game control board 40 supported rotatably on the back side of the pachinko gaming machine via the case support device 300 are selectively visible. May be.

  Next, a pachinko gaming machine 1001 as Example 2 of the present invention will be described based on FIGS.

  First, an overall configuration of a pachinko gaming machine 1001 that is another example of the gaming machine will be described. As shown in FIGS. 20 and 21, the pachinko gaming machine 1001 includes an outer frame 1110 formed in a vertically long rectangular shape, and a game frame 1100 attached to the inside of the outer frame 1110 so as to be openable and closable. Further, the pachinko gaming machine 1001 has a glass door frame 1002 formed in a frame shape provided in the gaming frame 1100 so as to be openable and closable. The game frame 1100 includes a front frame 1002 that can be freely opened and closed with respect to the outer frame 1110, a mechanism plate (not shown) to which mechanism parts and the like are attached, and various parts (game board 1006 described later) attached to them. Except for).

  A hitting ball supply tray (upper plate) 1003 is provided on the lower surface of the glass door frame 1002. Under the hitting ball supply tray 1003, there are provided an extra ball receiving tray 1004 for storing game balls that cannot be accommodated in the hitting ball supply tray 1003, and a hitting operation handle (operation knob) 1005 for firing the hitting ball. A game board 1006 is detachably attached to the back surface of the glass door frame 1002. The game board 1006 is a structure including a plate-like body constituting the game board 1006 and various components attached to the plate-like body. In addition, a game area 1007 is formed on the front surface of the game board 1006 in which a game ball that has been struck can flow down.

  In the vicinity of the center of the game area 1007, an effect display device 1009 configured by a liquid crystal display device (LCD) is provided. In the effect display device 1009, variable display (variation) of the effect symbol (decorative symbol) is performed in synchronization with the variable display of the first special symbol or the second special symbol. Therefore, the effect display device 1009 corresponds to a variable display device that performs variable display of effect symbols (decorative symbols) as identification information. The effect display device 1009 is controlled by an effect control microcomputer mounted on the effect control board. When the first special symbol display device 1008a is executing variable display of the first special symbol, the effect control microcomputer causes the effect display device 1009 to execute the effect display along with the variable display, and the second special symbol display device 1008a executes the second special display. When the variable display of the second special symbol is executed on the symbol display 1008b, the effect display is executed by the effect display device in accordance with the variable display, so that it is possible to easily grasp the progress of the game.

  A first special symbol display (first variable display means) 1008a for variably displaying the first special symbol as identification information is provided on the left side of the top of the effect display device 1009 in the game board 1006. In this embodiment, the first special symbol display device 1008a is realized by a simple and small display device (for example, 7 segment LED) capable of variably displaying numbers 0 to 9. That is, the first special symbol display 1008a is configured to variably display numbers (or symbols) from 0 to 9. A second special symbol display (second variable display means) 1008b that variably displays a second special symbol as identification information is provided on the right side of the upper portion of the effect display device 1009 in the game board 1006. The second special symbol display 1008b is realized by a simple and small display (for example, 7 segment LED) capable of variably displaying numbers 0 to 9. That is, the second special symbol display 1008b is configured to variably display numbers (or symbols) from 0 to 9.

  In this embodiment, the type of the first special symbol and the type of the second special symbol are the same (for example, both 0 to 9), but the types may be different. In addition, the first special symbol display device 1008a and the second special symbol display device 1008b may be configured to variably display numbers (or two-digit symbols) of, for example, 00 to 99.

  Hereinafter, the first special symbol and the second special symbol may be collectively referred to as a special symbol, and the first special symbol indicator 1008a and the second special symbol indicator 1008b may be collectively referred to as a special symbol indicator.

  For the variable display of the first special symbol or the second special symbol, the first start condition or the second start condition, which is the execution condition of the variable display, is satisfied (for example, the game ball has the first start winning opening 1013 or the second start winning opening) 1014), a variable display start condition (for example, when the number of reserved memories is not 0 and the variable display of the first special symbol and the second special symbol is not executed) When the variable display time (fluctuation time) elapses, the display result (stop symbol) is derived and displayed. Note that winning means that a game ball has entered a predetermined area such as a winning opening. Deriving and displaying the display result means that the symbol (example of identification information) is finally stopped and displayed.

  The effect display device 1009 is for decoration (effect) during the variable display time of the first special symbol on the first special symbol display device 1008a and during the variable display time of the second special symbol on the second special symbol display device 1008b. Display design (also referred to as a decorative design) as a design. The variable display of the first special symbol on the first special symbol display 1008a and the variable display of the effect symbol on the effect display device 1009 are synchronized. The variable display of the second special symbol on the second special symbol display device 1008b and the variable display of the effect symbol on the effect display device 1009 are synchronized. Synchronous means that the start time and end time of variable display are substantially the same (may be exactly the same) and the variable display period is substantially the same (may be exactly the same). In addition, when the jackpot symbol is stopped and displayed on the first special symbol display 1008a and when the jackpot symbol is stopped and displayed on the second special symbol display 1008b, the effect display device 1009 causes the jackpot to be recalled. The combination of is stopped and displayed.

  Below the effect display device 1009, a winning device having a first start winning port 1013 is provided. The game ball that has won the first start winning opening 1013 is guided to the back of the game board 1006 and detected by the first start opening switch 1013a.

  A variable winning ball device 1015 having a second starting winning port 1014 through which a game ball can be won is provided below the winning device having the first starting winning port (first starting port) 1013. The game ball that has won the second start winning opening (second start opening) 1014 is guided to the back of the game board 1006 and detected by the second start opening switch 1014a. The variable winning ball apparatus 1015 is opened by a solenoid 1016. When the variable winning ball apparatus 1015 is in the open state, the game ball can be won in the second start winning opening 1014 (it is easier to start winning), which is advantageous to the player. In the state where the variable winning ball apparatus 1015 is in the open state, it is easier for the game ball to win the second starting winning hole 1014 than the first starting winning hole 1013. In addition, in a state where the variable winning ball device 1015 is in the closed state, the game ball does not win the second start winning port 1014. In the state where the variable winning ball apparatus 1015 is in the closed state, it may be configured such that although it is difficult to win, it is possible to win (that is, the game ball is difficult to win).

  Hereinafter, the first start winning opening 1013 and the second start winning opening 1014 may be collectively referred to as a start winning opening or a starting opening.

  When the variable winning ball device 1015 is controlled to be in the open state, the game ball heading toward the variable winning ball device 1015 is very likely to win the second start winning port 1014. The first start winning opening 1013 is provided immediately below the effect display device 1009, but the interval between the lower end of the effect display device 1009 and the first start winning port 1013 is further reduced, or the first start winning port is set. The winning percentage of the second starting prize opening 1014 is such that nails are densely arranged around the area 1013 or the nail arrangement around the first starting prize opening 1013 is difficult to guide the game ball to the first starting prize opening 1013. This may be higher than the winning rate of the first start winning opening 1013.

  At the bottom of the first special symbol display 1008a, the number of effective winning balls that have entered the first start winning opening 1013, that is, the first reserved memory number (the reserved memory is also referred to as the start memory or the start prize memory) is displayed 4. A first special symbol storage memory display 1018a made up of two indicators (for example, LEDs) is provided. The first special symbol storage memory display 1018a increases the number of indicators to be lit by 1 each time there is an effective start winning. Then, each time the variable display on the first special symbol display 1008a is started, the number of indicators to be turned on is reduced by one.

  Below the second special symbol display 1008b is a second special symbol hold comprising four indicators (for example, LEDs) for displaying the number of effective winning balls that have entered the second start winning opening 1014, that is, the second reserved memory number. A storage indicator 1018b is provided. The second special symbol storage memory display 1018b increases the number of indicators that are turned on by one every time there is an effective start winning. Each time variable display on the second special symbol display device 1008b is started, the number of display devices that are lit is reduced by one.

  Further, the display screen of the effect display device 1009 is provided with a first reserved memory display unit 1018c for displaying the first reserved memory number and a second reserved memory display unit 1018d for displaying the second reserved memory number. . In addition, you may make it provide the area | region (sum total pending | holding memory display part) which displays the total number (sum total pending memory count) which is the sum total of the 1st pending memory count and the 2nd pending memory count. As described above, if the summation pending storage display section for displaying the total number is provided, it is possible to easily grasp the total number of execution conditions that are not satisfied with the variable display start condition.

  In this embodiment, as shown in FIG. 20, a variable winning ball device 1015 that opens and closes only with respect to the second starting winning opening 1014 is provided. However, the first starting winning opening 1013 and the second starting winning opening 1013 are provided. Any of the winning openings 1014 may be provided with a variable winning ball apparatus that performs an opening / closing operation.

  As shown in FIG. 20, a special variable winning ball apparatus 1020 is provided below the variable winning ball apparatus 1015. The special variable winning ball apparatus 1020 includes an opening / closing plate, and when a specific display result (big win symbol) is derived and displayed on the first special symbol display device 1008a, and on the second special symbol display device 1008b, a specific display result (big hit symbol). When the open / close plate is controlled to be open by the solenoid 1021 in the specific game state (big hit game state) that occurs when the symbol is derived and displayed, the big winning opening serving as the winning area is opened. A game ball that has won a big winning opening is detected by the count switch 1023.

  A normal symbol display 1010 is provided at the lower right side of the game board 1006. The normal symbol display 1010 variably displays a plurality of types of identification information (for example, “◯” and “x”) called normal symbols.

  When the game ball passes through the gate 1032 and is detected by the gate switch 1032a, the variable display of the normal symbol display 1010 is started. In this embodiment, variable display is performed by alternately lighting the upper and lower lamps (the symbols can be visually recognized when turned on). For example, if the lower lamp is turned on at the end of the variable display, it is a hit. And when the stop symbol in the normal symbol display 1010 is a predetermined symbol (winning symbol), the variable winning ball apparatus 1015 is opened for a predetermined number of times. That is, the state of the variable winning ball apparatus 1015 is a state that is advantageous from a disadvantageous state for the player when the stop symbol of the normal symbol is a winning symbol (a state in which a game ball can be awarded at the second start winning port 1014). To change. In the vicinity of the normal symbol display 1010, a normal symbol hold storage display 1041 having four indicators (for example, LEDs) for displaying the number of winning balls that have passed through the gate 1032 is provided. Each time there is a game ball passing through the gate 1032, that is, every time a game ball is detected by the gate switch 1032 a, the normal symbol holding storage display 1041 increases the number of indicators that are turned on by one. Then, each time the variable display of the normal symbol display 1010 is started, the number of indicators that are lit is reduced by one. Further, in the probability variation state in which the probability of being determined to be a big hit compared to the normal state is high, the probability that the stop symbol in the normal symbol display 1010 becomes a winning symbol is increased, and the variable winning ball apparatus 1015 The opening time becomes longer and the number of opening times is increased. That is, the game ball is controlled to be in a high base state that is controlled so as to make it easier for the game ball to start and win (that is, the execution condition of variable display in the special symbol displays 1008a and 1008b and the effect display device 1009 is easily established). Transition. Further, in this embodiment, even in the short-time state (the game state in which the special symbol variable display time is shortened), the opening time of the variable winning ball device 1015 becomes longer and the number of times of opening is increased.

  In addition, by extending the time during which the variable winning ball device 1015 is in the open state (also referred to as the open extended state), it becomes easier for the game ball to enter the start winning opening (that is, the special symbol indicators 108a and 108b and the effect display). It is also possible to shift to a high base state, which is a gaming state controlled so that a variable display execution condition in the device 1009 is easily established.

  Also, instead of extending the time during which the variable winning ball apparatus 1015 is in the open state, the normal symbol display unit 1010 shifts to the normal symbol probability changing state in which the probability that the stopped symbol becomes a winning symbol is increased, so that the high base state is achieved. You may migrate. When the stop symbol in the normal symbol display 1010 becomes a predetermined symbol (winning symbol), the variable winning ball apparatus 1015 is opened for a predetermined number of times. In this case, by controlling the transition to the normal symbol probability changing state, the probability that the stop symbol in the normal symbol display 1010 becomes a winning symbol is increased, and the frequency at which the variable winning ball apparatus 1015 is opened is increased. Therefore, if the normal symbol probability changing state is entered, the opening time and the number of opening times of the variable winning ball apparatus 1015 are increased, and the start winning state is easily set (high base state). That is, the opening time and the number of times of opening of the variable winning ball apparatus 1015 are increased when the stop symbol of the normal symbol is a winning symbol, or when the stop symbol of the special symbol is a probabilistic symbol. It changes to an advantageous state (a state where it is easy to win a start). Note that increasing the number of times of opening is a concept including changing from a closed state to an open state.

  Moreover, you may transfer to a high base state by shifting to the normal symbol time-short state where the fluctuation time (variable display period) of the normal symbol in the normal symbol display 1010 is shortened. In the normal symbol short-time state, the variation time of the normal symbol is shortened, so that the frequency of starting the variation of the normal symbol increases, and as a result, the frequency of hitting the normal symbol increases. Therefore, when the frequency that the normal symbol is hit increases, the frequency that the variable winning ball apparatus 1015 is opened is increased, and the start winning state is easily set (high base state).

  Also, by shifting to the short time state when the variation time (variable display period) of special symbols and production symbols is shortened, the variation time of special symbols and production symbols is shortened, so that effective start winnings are likely to occur. The possibility that a big hit game is played increases.

  Furthermore, by making transitions to all the states shown above (open extended state, normal symbol probability change state, normal symbol short time state, and special symbol short time state), it will be easier to win a start (shift to a high base state). May be. In addition, it becomes easier to win a start (high base) by shifting to any one of the above states (open extended state, normal symbol probability changing state, normal symbol short time state, and special symbol short time state). Transition to a state).

  A decoration LED 1025 flashing during the game is provided around the left and right of the game area 1007 of the game board 1006, and an out port 1026 into which a hit ball that has not won a prize is taken in at the bottom. In addition, two speakers 1027R and 1027L that utter sound effects and sounds as predetermined sound outputs are provided on the left and right upper portions outside the game area 1007. A top frame LED 1028a, a left frame LED 1028b, and a right frame LED 1028c provided on the front frame are provided at the outer periphery upper portion, the outer periphery left portion, and the outer periphery right portion of the game area 1007. Also, a prize ball LED 1051 that is turned on when there is a remaining number of prize balls is provided in the vicinity of the left frame LED 1028b, and a ball cut LED 1052 that is turned on when the supply ball is cut is provided in the vicinity of the right frame LED 1028c. . The top frame LED 1028a, the left frame LED 1028b, the right frame LED 1028c, and the decoration LED 1025 are examples of effects light emitters provided in the pachinko gaming machine 1001. In addition to the above-mentioned various LEDs for effects (decorations), LEDs and lamps for effects are installed.

  In addition, an operation unit 1005 as an operation means that can be operated by the player is provided on a member constituting the hit ball supply tray 1003. The operation unit 1005 is provided with a press operation unit made of a transparent resin member that can be turned on by an LED (not shown) inside the player. An operation switch (not shown) for detecting a pressing operation of the pressing operation unit is provided below.

  In the gaming machine, a ball hitting device (not shown) that drives a driving motor in response to the player operating the hitting operation handle 1005 and uses the rotational force of the driving motor to launch a gaming ball to the gaming area 1007. Is provided. A game ball launched from the ball striking device enters the game area 1007 through a ball hitting rail formed in a circular shape so as to surround the game area 1007, and then descends the game area 1007. When the game ball enters the first start winning port 1013 and is detected by the first start port switch 1013a, if the variable display of the first special symbol can be started (for example, the variable display of the special symbol ends, 1), the first special symbol display 1008a starts variable display (variation) of the first special symbol, and the effect display device 1009 starts variable display of the effect symbol (decoration symbol). Is done. In other words, the variable display of the first special symbol and the effect symbol corresponds to winning in the first start winning opening 1013. If the variable display of the first special symbol cannot be started, the first reserved memory number is increased by 1 on the condition that the first reserved memory number has not reached the upper limit value.

  When the game ball enters the second start winning port 1014 and is detected by the second start port switch 1014a, if the variable display of the second special symbol can be started (for example, the special symbol variable display ends, 2), the second special symbol display 1008b starts variable display (variation) of the second special symbol, and the effect display device 1009 starts variable display of the effect symbol (decoration symbol). Is done. That is, the variable display of the second special symbol and the effect symbol corresponds to winning in the second start winning opening 1014. If the variable display of the second special symbol cannot be started, the second reserved memory number is increased by 1 on condition that the second reserved memory number has not reached the upper limit value.

  The main board 1031 is equipped with a game control microcomputer (control microcomputer) 1560 for controlling the pachinko gaming machine 1001 according to a program. The game control microcomputer 1560 includes a ROM 1054 for storing a game control (game progress control) program and the like, a RAM 1055 as storage means used as a work memory, a CPU 1056 for performing control operations in accordance with the program, and an I / O port unit 1057. including. In this embodiment, the ROM 1054 and the RAM 1055 are built in the game control microcomputer 1560. That is, the game control microcomputer 1560 is a one-chip microcomputer. The one-chip microcomputer may include at least the RAM 1055 in addition to the CPU 1056, and the ROM 1054 may be externally attached or built-in. Further, the I / O port unit 1057 may be externally attached. The game control microcomputer 1560 further includes a random number circuit 1053 that generates hardware random numbers (random numbers generated by the hardware circuit).

  In the game control microcomputer 1560, the CPU 1056 executes control in accordance with the program stored in the ROM 1054. Therefore, the game control microcomputer 1560 (or CPU 1056) executes (or performs processing) hereinafter. Specifically, the CPU 1056 executes control according to a program. The same applies to microcomputers mounted on substrates other than the main substrate 1031.

  The random number circuit 1053 is a hardware circuit that is used to generate a random number for determination to determine whether or not to win a jackpot based on a display result of variable symbol special display. The random number circuit 1053 updates numerical data in accordance with a set update rule within a numerical range in which an initial value (for example, 0) and an upper limit value (for example, 65535) are set, and starts at a random timing Based on the fact that the winning time is the reading (extraction) of the numerical data, it has a random number generation function in which the numerical data to be read becomes a random value.

  The random number circuit 1053 has a numeric data update range selection / setting function (initial value selection / setting function and upper limit selection / setting function), numeric data update rule selection / setting function, and numeric data update rule selection. It has various functions such as a switching function. With such a function, the randomness of the generated random numbers can be improved.

  Further, the game control microcomputer 1560 has a function of setting an initial value of numerical data updated by the random number circuit 1053. For example, a predetermined calculation is performed using an ID number of the game control microcomputer 1560 (an ID number assigned to each product of the game control microcomputer 1560) stored in a predetermined storage area such as the ROM 1054. The numerical data obtained by the execution is set as an initial value of the numerical data updated by the random number circuit 1053. By performing such processing, the randomness of the random number generated by the random number circuit 1053 can be further improved.

  The game control microcomputer 1560 reads the numerical data as random R from the random number circuit 1053 when the start winning to the first start port switch 1013a or the second start port switch 1014a occurs, and starts to change the special symbol and the effect symbol. Sometimes it is determined whether or not to make a jackpot display result as a specific display result based on the random R, that is, whether or not to make a jackpot display result. Then, when it is determined to be a big hit, the gaming state is shifted to a big hit gaming state as a specific gaming state advantageous to the player.

  The RAM 1055 is a backup RAM as a non-volatile storage means, part or all of which is backed up by a backup power source created on the power supply board. That is, even if the power supply to the gaming machine is stopped, a part or all of the contents of the RAM 1055 is stored for a predetermined period (until the capacitor as the backup power supply is discharged and the backup power supply cannot be supplied). In particular, at least data corresponding to the game state, that is, the control state of the game control means (the value of the special symbol process flag or the total pending storage number counter) and the data indicating the number of unpaid winning balls are stored in the backup RAM. The data corresponding to the control state of the game control means is data necessary for restoring the control state before the occurrence of a power failure or the like based on the data when the power is restored after a power failure or the like occurs. Further, data corresponding to the control state and data indicating the number of unpaid winning balls are defined as data indicating the progress state of the game. In this embodiment, it is assumed that the entire RAM 1055 is backed up.

  A reset signal (not shown) from the power supply board is input to the reset terminal of the game control microcomputer 1560. A reset circuit for generating a reset signal supplied to the game control microcomputer 1560 and the like is mounted on the power supply board. When the reset signal becomes high level, the game control microcomputer 1560 and the like become operable, and when the reset signal becomes low level, the game control microcomputer 1560 and the like become inoperative. Therefore, an allowable signal that allows the operation of the game control microcomputer 1560 or the like is output during a period when the reset signal is at a high level, and a game control microcomputer when the reset signal is at a low level. An operation stop signal for stopping the operation of 1560 or the like is output. Note that the reset circuit may be mounted on each electric component control board (a board on which a microcomputer for controlling the electric parts is mounted).

  Furthermore, a power-off signal indicating that the power supply voltage from the power supply board has dropped below a predetermined value is input to the input port of the game control microcomputer 1560. That is, the power supply board monitors the voltage value of a predetermined voltage (for example, DC30V or DC5V) used in the gaming machine, and when the voltage value decreases to a predetermined value (the power supply voltage is reduced). A power supply monitoring circuit that outputs a power-off signal indicating that). A clear signal (not shown) indicating that the clear switch for instructing to clear the contents of the RAM is operated is input to the input port of the game control microcomputer 1560.

  An input driver circuit 1058 that supplies detection signals from the gate switch 1032a, the first start port switch 1013a, the second start port switch 1014a, and the count switch 1023 to the game control microcomputer 1560 is also mounted on the main board 1031. Also, an output circuit 1059 for driving the solenoid 1016 for opening and closing the variable winning ball apparatus 1015 and the solenoid 1021 for opening and closing the special variable winning ball apparatus 1020 for forming the big winning opening according to a command from the game control microcomputer 1560 is also provided. 1031. Further, an information output circuit (not shown) for outputting an information output signal such as jackpot information indicating the occurrence of a jackpot gaming state to an external device such as a hall computer is also mounted on the main board 1031.

  In this embodiment, the effect control means (configured by the effect control microcomputer) mounted on the effect control board 1080 directs the contents of the effect from the game control microcomputer 1560 via the relay board 1077. A control command is received, and display control is performed with an effect display device 1009 that variably displays effect symbols.

  The effect control board 1080 is equipped with an effect control microcomputer (not shown) including an effect control CPU and a RAM. The RAM may be externally attached. In the effect control board 1080, the effect control CPU operates in accordance with a program stored in a built-in or external ROM (not shown) and receives a signal (effect) from the main board 1031 input via the relay board 1077. In response to the control INT signal), an effect control command is received via the input driver and the input port. Further, the effect control CPU causes the VDP (video display processor) to perform display control of the effect display device 1009 based on the effect control command.

  The effect control CPU 101 reads necessary data from a character ROM (not shown) in accordance with the received effect control command. The character ROM is for storing character image data displayed on the effect display device 1009, specifically, a person, characters, figures, symbols, etc. (including effect symbols) in advance. The effect control CPU outputs data read from the character ROM to a VDP (not shown). The VDP executes display control based on data input from the effect control CPU 101.

  The effect control command and the effect control INT signal are first input to an input driver (not shown) on the effect control board 1080. The input driver allows the signal input from the relay board 1077 to pass only in the direction toward the inside of the effect control board 1080 (does not pass the signal in the direction from the inside of the effect control board 1080 to the relay board 1077). It is also a unidirectional circuit as a means.

  As a signal direction regulating means, the signal inputted from the main board 1031 is allowed to pass through the relay board 1077 only in the direction toward the effect control board 1080 (the signal is not passed in the direction from the effect control board 1080 to the relay board 1077). A unidirectional circuit (not shown) is mounted. For example, a diode or a transistor is used as the unidirectional circuit. A unidirectional circuit is provided for each signal. Furthermore, since the production control command and the production control INT signal are output from the main board 1031 via the I / O port unit 1057 which is a unidirectional circuit, a signal from the relay board 1077 to the inside of the main board 1031 is restricted. The That is, the signal from the relay board 1077 does not enter the inside of the main board 1031 (the game control microcomputer 1560 side). The I / O port unit 1057 is a part of the I / O port unit 1057 shown in FIG. Further, a signal driver circuit that is a unidirectional circuit may be further provided outside the I / O port portion 1057 (on the relay board 1077 side).

  Further, the effect control CPU 101 outputs a signal for driving the LED to the lamp driver substrate 1035 via an output port (not shown). Further, the effect control CPU outputs sound number data to the sound control board 1070 via an output port (not shown).

  In the lamp driver board 1035, a signal for driving the LED is input to the LED driver (not shown) via an input driver (not shown). The LED driver (not shown) supplies a drive signal to each LED provided on the frame side such as the top frame LED 1028a, the left frame LED 1028b, and the right frame LED 1028c. Further, a drive signal is supplied to the decoration LED 1025 provided on the game board side. When a light emitter other than the LED is provided, a drive circuit (driver) for driving the light emitter is mounted on the lamp driver substrate 1035.

  In the voice output board 1070, the sound number data is input to a voice synthesis IC (not shown) via an input driver (not shown). The voice synthesizing IC generates voice and sound effects corresponding to the sound number data and outputs them to an amplifier circuit (not shown). The amplifier circuit outputs an audio signal obtained by amplifying the output level of the speech synthesis IC to a level corresponding to the volume set by the volume to the speakers 1027R and 1027L. Control data corresponding to sound number data is stored in a sound data ROM (not shown). The control data corresponding to the sound number data is a collection of data showing the output form of the sound effect or sound in a time series in a predetermined period (for example, the changing period of the effect design).

  The effect control CPU is connected to the operation unit 1005 via an input / output port, and outputs a signal for driving an LED (not shown) in the operation unit 1005 via the input / output port. An operation signal output in response to a player's pressing operation is input from an operation switch (not shown) in the unit 1005.

Thereby, since it becomes impossible to reproduce a sealing state using the destroyed base member 1201, fraudulent act can be suppressed.

  Such a groove may be formed not only on the left side wall of the base member 1201, but also on other side walls, other parts, etc., or may be formed on the cover member 1202 side. It is preferable to form it at a place where an illegal instrument such as the vicinity of a stopper or a welded portion is easily inserted.

  As shown in FIG. 25, a cover side sealing portion 1224 is formed on the right side wall 1202c of the cover member 1202, and a cover side welding portion 1223 is provided in the center on the left side wall 1202d, and the cover A screw covering piece 1602 that covers the spare one-way screw 1240b is provided on the upper side of the side welded portion 1223, and an attachment sealing piece 1230 through which the one-way screw 1240a for attachment sealing is inserted and a latch on the lower side. A piece 1603 is formed. The screw covering piece 1602 is locked to the locked piece 1602a of the base member 1201 in the closed state, and the locking piece 1603 is locked to the locked piece 1603a of the base member 1201 in the closed state.

  It should be noted that the welded portion composed of the base-side welded portion 1207 and the cover-side welded portion 1223 and the sealing mounting portion composed of the mounting sealing hole 1601 and the mounting sealing piece 1230 are functionally different only in the shape and the like. 1 is configured in substantially the same manner as the welded portion and the sealing attachment portion of the substrate case 200 and has the same functions and effects, and thus detailed description thereof is omitted.

  As shown in FIGS. 27 and 28, the base-side sealing portion 1229 has a base-side application surface composed of a front application surface 1229a and a lower right application surface 1229b, and above and below each of the application surfaces 1229a and 1229b, Positioning ridges 1411 and 1411 and positioning corners 1412 and 1412 are formed. The front sticking surface 1229a is formed so as to face an opening 1610b of a recess 1610a for storing the head, which is formed on one end side of a mounting hole 1610 for mounting the closing screw 1226, and the closing screw 1226 is attached to the opening 1610b. Can be inserted through the mounting hole 1610 and attached.

  The cover-side sealing portion 1224 has a cover-side pasting surface consisting only of the upper right pasting surface 1224b, and positioning ridges 1421, 1421 and positioning corners 1422, 1422 are formed above and below the upper right pasting surface 1224b. A screw hole 1611 to which a closing screw 1226 is attached is formed in the front end surface of the cover side sealing portion 1224, and the closing screw 1226 inserted through the attaching hole 1610 is screwed therein.

  The lower right sticking surface 1229b and the upper right sticking surface 1224b formed along the left side surface of the substrate case 1200 are formed when the base member 1201 and the cover member 1202 are closed (see FIG. 26). A flat surface-like first pasting surface that is continuous along the right side surface is configured, and the area of the first pasting surface composed of these pasting surfaces 1229b and 1224b is lateral to the right side surface of the substrate case 1200. It is made larger than the area of the 2nd sticking surface which consists of the front sticking surface 1229a protrudingly provided.

  As described above, the first pasting surface disposed substantially parallel to the right side surface of the substrate case 1200 is used as the second pasting surface disposed substantially parallel to the cover plate 1202a and the base plate 1201a of the substrate case 1200. 28, and the peripheral edge of the first sticking surface is arranged inside the peripheral edge of the side surface of the substrate case 1200, so that the second sticking surface is formed from the right side surface of the substrate case 1200 as shown in FIG. Since the first sticking surface is enlarged as much as possible within the range of the side surface of the substrate case 1200, a wide sticker attaching surface can be secured without making the substrate case protrude greatly to the side, so that the substrate case 1200 can be made compact. Alternatively, it can be avoided that a seal 1400, which will be described later, protrudes to the side of the substrate case 1200 and easily comes into contact with peripheral devices, components, and the like.

  Further, the first sticking surface that is continuous across the boundary Z between the base member 1201 and the cover member 1202 and the second sticking surface that faces in a direction different from the first sticking surface and is formed with the opening 1610b are sealed. An affixing surface is formed, and the seal seal 1400 is affixed so as to cover the boundary Z and the opening 1610b, so that not only when the assembly of the base member 1201 and the cover member 1202 is released, but also the base member 1201. Since the trace remains even when the closing screw 1226 is removed from the screw hole 1611 in order to release the assembly of the cover member 1202 and the cover member 1202, it is easy to discover that the second sealing state may be released. In addition, since a corner portion C10 of about 90 degrees (bent portion, see FIG. 29B) is formed between the first sticking surface and the second sticking surface, the sealing seal 1 00 damage when attempting to peeling is likely to occur.

  Incidentally, as shown in FIG. 28, the cut-out sides 1410 of the corners are attached to these sticking surfaces so as to match the positioning surfaces 1412a and 1422a in the same manner as the seal seal 400 of the first embodiment, thereby opening the openings 1610b. The second sealed state is configured by covering the head of the exposed closing screw 1226.

  As shown in FIG. 30, the seal seal 1400 is different from the seal seal 400 of the first embodiment in that the solvent use display units 1450A to 1450D, the first identification information display unit 1451, and the second identification information display unit 1452 are different. It is arranged in a horizontal direction and has a different position, and the other configurations are substantially the same, and therefore, detailed description here is omitted by giving the same reference numerals.

  Of the surface of the seal substrate 1401, the surface on which the pressure-sensitive adhesive layer 1402 is not formed, as shown in FIGS. 30 (a) to 30 (c), is specially dissolved in the stripping solution by contacting with the stripping solution. When the character “open prohibition” printed by ink is applied to the substrate case 1200 in a predetermined manner, the boundary portion Z between the cover member 1202 and the base member 1201 constituting the substrate case 1200 is displayed. (See FIG. 28 (a)) and printed and formed so as to be disposed at a portion not located at the corner C10 (see FIG. 29 (b)) in the seal sticker attaching portion.

  In addition, the sticking surface of the seal seal 1400 formed on the sealing portions 1229 and 1224 in the substrate case 1200 is not L-shaped like the sticking surface of the first embodiment, so that it extends along the left side surface. The formed first sticking surface can be made as large as possible, and the number of bent portions is one instead of two.

  As shown in FIG. 27, the seal protective cover 1228 is formed in a substantially L shape from a first covering piece 1620 that covers the outside of the first sticking surface and a second covering piece 1621 that covers the outside of the second sticking surface. Has been. The width dimension of the end portion side of the first covering piece 1620 is formed to be shorter than the width dimension of the base portion side of the first covering piece 1620 and the second covering piece 1621.

  A pair of upper and lower elastic locking pieces 1622 and 1622 are extended from the upper and lower short sides of the second covering piece 1621 toward the front side, and the elastic locking pieces 1622 and 1622 are covered with a cover in the cover member 1202. Locking claws 1622a that are inserted from the rear end openings of the locking piece insertion portions 1623 and 1623 formed on the upper and lower sides of the side sealing portion 1224 and project outwardly at the tips of the elastic locking pieces 1622 and 1622, respectively. , 1622a can be locked to the cover member 1202 by being locked in the locking holes 1624, 1624. Further, the locked state can be easily released by pressing the locking claws 1622a and 1622a locked in the locking holes 1624 and 1624 from the outside.

  As described above, the seal protection cover 1228 can be locked to the cover member 1202 by being pushed from the front side of the cover member 1202 toward the rear side. In the locked mounting state, the inner peripheral edges of the first covering piece 1620 and the second covering piece 1621 come into contact with the contact regulating surfaces 1413 and 1423 of the positioning protrusions 1411 and 1421 and the positioning portions 1412 and 1422, respectively. The opposed surfaces of the inner side sides of the first covering piece 1620 and the second covering piece 1621 and the surface 1400a of the seal seal 1400 are spaced apart from each other and maintained in a non-contact state. Therefore, even when the seal protection cover 1228 is slid back and forth while being in contact with the contact restriction surfaces 1413 and 1423 and is attached to and detached from the seal portions 1224 and 1229, the seal seal 1400 does not contact the seal seal 1400. Even if any external force is applied to the seal protection cover 1228 in the mounted state, the seal seal 1400 is not directly transmitted to the seal seal cover 1228, so that the seal seal 1400 is prevented from being damaged.

  Further, since the seal protection cover 1228 is composed of only the L-shaped first covering piece 1620 and the second covering piece 1621, the cover member 1202 with respect to the base member 1201 can be retained while being locked to the cover member 1202. Can be opened and closed. Therefore, for example, when the second sealing state is released in order to inspect the main substrate 1031, the locking state between the locking hole 1624 as the locked portion and the locking claw 1622 a as the locking portion is changed. By releasing, the seal protective cover 1228 can be easily removed. Further, even if the seal protection cover 1228 is removed to release the second sealing state, the seal protection cover 1228 can be locked to the cover member 1202, so that the seal protection cover 1228 can be prevented from being lost. In addition, since the cover member 1202 can be opened and closed in the locked state, the opening and closing operation can be easily performed.

  Further, the seal protective cover 1228 can be detachably attached to the cover member 1202 of the substrate case 1200 from the front side. Then, the substrate case 1200 is placed (attached) in a case placement position (see FIG. 21) provided on the back of the pachinko gaming machine 1001 (in this embodiment, the front surface of the base member 1201 is opposed to the placement surface. In this case, the front surface of the second covering piece 1621 of the seal protection cover 1228 is disposed so as to be in contact with or close to the arrangement surface, so that the seal protection cover 1228 is disposed in the case arrangement position. Even if it is going to be removed from the cover member 1202, the front surface of the second covering piece 1621 is abutted against the arrangement surface and cannot be removed from the substrate case 1200.

  Therefore, the board case 1200 is arranged at the case arrangement position, and the one-way screw 1240a is inserted into the above-described attachment sealing piece 1230 and screwed into the attachment portion formed at the case arrangement position, whereby the seal protective cover 1228 is installed. Since the movement in the removal direction is restricted by contact with the arrangement surface and cannot be removed from the substrate case 1200, illegal acts on the seal seal 1400 can be effectively prevented.

  Further, since the opening 1610b of the recess 1610a for accommodating the head of the closing screw 1226 is formed so as to face the second sticking surface parallel to the base plate 1201a, the board case 1200 is attached to the pachinko game as described above. In the state of being installed (attached) at the case arrangement position (see FIG. 21) provided in the machine 1001 (in this embodiment, the opening is arranged with the front surface of the base member 1201 facing the arrangement surface), the opening 1610b is Since it is arranged to face the arrangement surface, it is impossible to remove the closing screw 1226 while it is arranged at the case arrangement position, so it is difficult to open the cover member 1202.

  Note that the arrangement surface on which the substrate case 1200 is arranged may be formed of any part such as a constituent part constituting the pachinko gaming machine 1001 or a gaming component arranged in the pachinko gaming machine 1001.

  Further, the seal protection cover 1228 is not limited to the one in which the removal is restricted by contacting the arrangement surface in a state where the substrate case 1200 is arranged at the arrangement position, and is arranged at a place other than the arrangement surface. The pachinko gaming machine 1001 may be configured to abut or be restricted by a game component or the like disposed in the pachinko gaming machine 1.

  As described above, in the pachinko gaming machine 1001 as the second embodiment of the present invention, as shown in FIG. 30, on the surface of the seal substrate 1401, the solvent use display units 1450A to 1450D, the first identification information. The upper region R10 provided with the display unit 1451, the second identification information display unit 1452, and the hologram display unit 1453B is located on the upper right application surface 1224b and the lower right application surface 1229b of the cover side sealing unit 1224, and the hologram display unit 1453A is provided. The provided lower region R20 is located on the front sticking surface 1229a of the base-side sealing portion 1229.

  The seal seal 1400 is attached to the boundary Z between the cover member 1202 and the base member 1201 when the seal seal 1400 is pasted so as to straddle the base side seal portion 1229 and the cover side seal portion 1224 in the substrate case 1200. Since the solvent use display portions 1450A to 1450D are printed and formed in the non-positioned portion, the solvent use display portions 1450A to 1450D do not hang on the boundary portion Z when the sealing state is set. When the seal seal 1400 is broken for inspection of the game control board 40 and the board case 1200 is opened, the solvent use display portions 1450A to 1450D are broken, so that traces of contact with the solvent appear before that. It is prevented that it was difficult to understand what was happening.

  Specifically, the substrate case 1200 of the second embodiment can be opened by sliding the cover member 1202 with respect to the base member 1201, so that the sealing seal 1400 covers the base side sealing portion 1229 in the substrate case 1200 and the cover. When the substrate case 1200 is opened in the second sealing state applied so as to straddle the side sealing portion 1224, a portion corresponding to the boundary portion Z in the sealing seal 1400 is easily broken. Therefore, in the seal 1400, when any one of the solvent use display portions 1450A to 1450D is printed on a portion that is applied to (corresponding to) the boundary portion Z when the base side seal portion 1229 and the cover side seal portion 1224 are attached. Even if the solvent use display portions 1450A to 1450D are dissolved by the use of the solvent, for example, by opening the substrate case 1200 for inspection of the main substrate 1031 or the like at the amusement store, the boundary portion Z of the seal seal 1400 is changed. Since it breaks and it becomes difficult to determine whether the solvent use indicator disappears and disappears or disappears due to the breakage, it becomes difficult to understand that the trace of contact with the solvent appeared. Therefore, the solvent use display portions 1450A to 1450D are printed and formed on the portion not located at the boundary portion Z between the cover member 1202 and the base member 1201 when pasted so as to straddle the base side seal portion 1229 and the cover side seal portion 1224. Has been.

  Further, the seal seal 1400 is displayed on the upper region R10, which is a portion facing in the same direction (upward) when attached to the substrate case 1200, and the first identification information display as the identification information display unit as the solvent use display units 1450A to 1450D. Since the unit 1451 and the second identification information display unit 1452 are arranged, both the solvent use display units 1450A to 1450D and the first identification information display unit 1451 and the second identification information display unit 1452 can be visually recognized together. This makes it possible to easily check the solvent use display units 1450A to 1450D, the first identification information display unit 1451, and the second identification information display unit 1452, thereby reducing the work load.

  In the second embodiment, the solvent use display portion and the identification information display portion are printed in the upper region R10 that is a portion facing the right side when the seal sticker 1400 is attached to the substrate case 1200. The lower region R20 may be printed.

  Moreover, in the present Example 2, although solvent use display part 1450A-1450D and the 1st identification information display part 1451 and the 2nd identification information display part 1452 as an identification information display part are arrange | positioned in upper area | region R10, Only at least one of the first identification information display unit 1451 and the second identification information display unit 1452 may be disposed as the information display unit. Other identification information may also be arranged.

  Further, corners formed between one pasting surface and the other pasting surface when pasting across a plurality of pasting surfaces, specifically, a front pasting surface 1229a and a lower right pasting surface 1229b, When the solvent use display portions 1450A to 1450D are arranged in a portion that is not located at the corner portion C10 (see FIG. 29B) formed between (see FIG. 30), and is attached to the substrate case 1200. Further, since the solvent use display portions 1450A to 1450D are not hung on the corner C10, it is possible to prevent the visibility of the solvent use display portions 1450A to 1450D from being impaired by bending the characters.

  Further, in the second embodiment, the seal protection cover 1228 is made of a transparent synthetic resin material, so that even when it is covered with the seal protection cover 1228, the seal protection cover 1228 passes through the seal protection cover 1228 to Since it is possible to confirm whether the usage display portions 1450A to 1450D have disappeared or become thin, it can be easily confirmed.

  Further, as shown in FIG. 21, in the second embodiment, the substrate case 1200 is attached at a substantially central position on the back surface of the pachinko gaming machine 1001. A connector opening 1236 facing a board-side connector (not shown) to which various cables 1700 are connected is disposed along the upper side of the board case 1200. Then, these cables 1700 connected to the main board 1031 are collectively inserted into, for example, a right side wiring insertion portion 1750.

  That is, the cable 1700 having one end connected to the main board 1031 is held by a wiring holding part such as the wiring insertion part 1750 disposed at the right side position of the board case 1200. The seal 1400 attached to the lower position of the cable 1700 is not covered with the seal 1400 by overlapping the wiring of the cable 1700 or the like. Therefore, in the seal seal 1400, the solvent use display portions 1450A to 1450D are arranged in a portion that does not overlap with the wiring such as the cable 1700 when the seal seal 1400 is affixed to the substrate case 1200.

  In other words, the sealing sticker 1400 is arranged at a position where it does not overlap with or near a straight line connecting the board-side connector of the main board 1031 and the wiring holding part such as the wiring insertion part 1750 when attached to the board case 1200. Therefore, it is prevented that the solvent use display units 1450A to 1450D are hidden by the wiring and the visibility of the solvent use display units 1450A to 1450D is impaired.

  In the first and second embodiments, as an example of wiring, the cables 600a to 600c, 600k, the main board 1031, and other relay boards that connect various electrical components via the game control board 40 and other relay boards are used. Although the cable 1700 for connecting various electrical components to each other has been described, these wirings are not limited to those described in the above cable, but the back side of the gaming machine, that is, the casing 1a of the slot machine 1 is used. Including all wirings for electrically connecting a plurality of electrical components (for example, various switches, sensors, solenoids, motors, LEDs, etc.) installed inside or behind the pachinko gaming machine 1001.

  Further, in the second embodiment, the seal seal 1400 is provided at a predetermined portion of the seal seal 1400 by providing a corner-side cut 1408 as a fragile portion whose strength of the seal seal 1400 is lower than that of other portions. Since the corner-side notch 1408 is easily broken at the time of peeling, it is possible to suppress an illegal act such as reattaching the seal seal 1400 peeled by the solvent.

  In the second embodiment, the seal seal 1400 includes a first identification information display unit 1451 in which a serial number or the like, which is identification information that can identify each seal seal 1400, is displayed so as to be visually readable. A second identification information display unit 1452 that can be read by a predetermined reading device (not shown) by encoding a two-dimensional barcode or the like that is identification information that can identify the seal seal 400; The identification information is read from the second identification information display unit 1452 by providing the second identification information display unit 1452 that can be read only by a predetermined reading device separately from the first identification information display unit 1451. Is difficult, and it takes time to forge the seal seal 1400, so that the security is improved.

  Further, in the second embodiment, the protruding strips 1411 and 1421 that are the peripheral wall portions are provided around the sealing portion including the base-side sealing portion 1229 and the cover-side sealing portion 1224 so as to surround the pasted sealing seal 1400. By being formed, when the seal seal 400 is peeled off, the surrounding ridges 1411 and 1421 become obstructive and difficult to peel off, so that it is possible to suppress an illegal act such as reattaching the seal seal 400 peeled by the solvent. .

  In addition, in the present Example 2, the peripheral wall part was formed by the protruding item | line, However, A peripheral wall part may be formed in the surrounding surface of this recessed part by using the recessed part formed in the plane as a sealing seal sticking part. .

  In the second embodiment, the seal sticker 1400 does not include an electronic tag (IC tag) that can read identification information (for example, a serial number) that can identify each seal sticker using a predetermined electromagnetic wave. In this way, an IC tag capable of reading the ID information stored in the IC chip with a predetermined reader device may be embedded in, for example, the adhesive layer 1402 of the seal sticker 1400. In this way, management of the identification information becomes easy, and since it is necessary to use a predetermined electromagnetic wave to read the identification information, it becomes time-consuming to forge the seal seal. Will improve.

  In the first and second embodiments, the base-side welding plate portion 261 (1261) and the cover-side welding plate portion 271 (joining portions to be joined to bring the base member 201 and the cover member 202 into a sealed state) 1271) and the opposing surfaces were joined by welding with an ultrasonic welding device (welding means), but the present invention is not limited to those where the joint is joined by welding with the welding means, For example, you may join by adhere | attaching with adhesive means, such as an adhesive agent.

  In the first and second embodiments, the recesses 227a and 1610a that can accommodate the heads of the closing screws 226 and 1226 are formed on the base-side application surface or the cover-side application surface, and the closing screws 226 are formed in the recesses 227a and 1610a. The openings 227b and 1610b, which are openings, are covered with the seals 400 and 1400 in a state in which the heads are accommodated, but only the mounting holes 227 and 1610 are formed without forming the recesses 227a and 1610a. You may form in a base side sticking surface or a cover side sticking surface. In this case, in the state where the closing screws 226 and 1226 are attached to the attachment holes 227 and 1610, the heads are arranged in a state where they are exposed on the base-side application surface or the cover-side application surface. The seal seals 400 and 1400 may be attached so as to directly cover the heads that are exposed portions exposed from 227 and 1610.

  In the first and second embodiments, the sealing seals 400 and 1400 are pasted so as to straddle the base-side pasting surface or the cover-side pasting surface. The second sealing state in which the trace that was opened by breaking was left, but the method of configuring the sealing state is as described above, the sealing seal 400, straddling the base side application surface or the cover side application surface, It is not limited to affixing 1400, For example, a sealing seal is affixed so that the closure screw which maintains the base member 201 and the cover member 202 in a closed state may be covered, and a closure screw is removed and it opens. In this case, the sealed state may be configured so that the seal seal is broken and the trace remains. That is, in this case, the sealed state can be configured without applying a seal seal to only one of the base member 201 and the cover member 202.

  In the first and second embodiments, the sealing seals 400 and 1400 for sealing the first covering body and the second covering body are described as an example of the sealing seal of the present invention. In addition to a sealing seal that seals the second cover, for example, a sealing seal for sealing so that a trace remains when a substrate case containing a circuit board is removed from a predetermined mounting portion. You may apply to. Further, a seal for sealing the first cover and the second cover and sealing so that a trace remains when the substrate case in which the circuit board is stored is removed from a predetermined mounting portion. It may be applied to a seal.

  Furthermore, the shapes of the base side application surface and the cover side application surface to which the seal seals 400 and 1400 are attached are not limited to the rectangular shape, and can be variously changed to a circular shape or a square shape. Further, the arrangement positions of the base-side pasting surface and the cover-side pasting surface may be arranged not on the short side portions of the substrate cases 200 and 1200 but on the long side portions.

  In the first and second embodiments, the base-side sticking surface and the cover-side sticking surface constitute a series of sticking surfaces that are continuous with each other in the closed state in which the base member 201 and the base member 201 are assembled. However, it may be arranged in a state of being separated from each other, or a stepped portion may be formed between the base side application surface and the cover side application surface. In addition, the boundary position between the base-side pasting surface and the cover-side pasting surface may not coincide with the boundary position between the base member 201 and the cover member 202.

  In the first and second embodiments, the seal protective covers 228 and 1228 can be detachably attached to the base member and / or the cover member. The base member or the cover member may be provided in advance so that the surface can be opened and closed.

  Further, since the seal protective covers 228 and 1228 are made of a transparent synthetic resin material, the surface of the sealed seal seals 400 and 1400 can be visually recognized through the seal protective covers 228 and 1228. You may be comprised with the optical member.

  Moreover, in the said Example 1, 2, the positioning part of a seal seal is comprised by the positioning protrusion 411,421 and the positioning corner | angular part 412,422 extended continuously along the periphery of a sticking surface of a seal | sticker. However, it may be arranged at predetermined intervals along the periphery of the sticking surface of the seal.

  Furthermore, the seal seal and the sticking surface of the seal were formed in a rectangular shape, but it is sufficient that the seal seal and the sticking surface are formed in a square shape. In such a case, the pair of cutout sides are arranged to face different directions. For example, since the position and orientation of the seal seal can be determined at a time, the seal seals may be formed at least at two corners that are opposed to each other on a diagonal line. Moreover, you may form in three or more corner | angular parts.

  Although the embodiments of the present invention have been described with reference to the drawings, the present invention is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. Needless to say.

  For example, in the first and second embodiments, the sealing seals 400 and 1400 for sealing the board cases 200 and 1200 containing the game control board 40 and the main board 1031 as an example of the circuit board have been described.
