Description

  The present invention relates to a gaming machine capable of performing a predetermined game, and a storage having a base body and a lid that can store a circuit board on which an electronic component for controlling an electrical component provided in the gaming machine is mounted. The present invention relates to a gaming machine including a case.

  A gaming machine such as a pachinko gaming machine or a slot machine is provided with a number of control boards such as a game control board for controlling a game. A game control microcomputer including a CPU, RAM, ROM and the like is mounted on the control board. 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 if 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, the game control board is stored in a board storage box including a box body and a lid. This type of substrate storage box is sealed by joining sealing pieces respectively provided on two opposite sides of the box body and the lid with one-way screws, and in this way a sealed state The board storage box is used to seal the box body and the lid on the other side with the locking pin provided on one side of the two sides locked to the main body of the gaming machine. By attaching the one-way screw to the main body of the gaming machine, the lid cannot be opened unless the joint is cut, and the board storage box cannot be removed from the main body of the gaming machine (for example, patents) Reference 1).

JP 2002-58786 A (page 6, FIG. 6)

  In the board storage box described in Patent Document 1, the box body can be sealed by fitting a lid body from above into the opening of the box body in which the game control board is housed. Since the sealing pieces provided on the two sides must be joined so that there is no gap between the cover and the lid, there is a problem that it takes time and manufacturing costs increase.

  The CPU 41a is provided with a plurality of registers (storage areas) for reading and writing data necessary for executing processing. Specifically, A and F registers (flag registers) that mainly store calculation data, B, C, D, E, H, and L registers that store general-purpose data, and data indicating the position of the program being executed PC register to be stored, SP register to store a stack pointer (an address indicating the current position of a stack area to be described later), an R register to store data indicating a memory block of the RAM 41c performing a refresh operation to be described later, and the RAM 41c There are provided IX and IY registers for storing data indicating a reference position when referring to a storage area, and an I register for storing data indicating the position of an interrupt table to be referred to when an interrupt occurs.

  The CPU 41a has an interrupt function (including an interrupt prohibition function) such as a timekeeping function and a timer interrupt, and executes a program (described later) stored in the ROM 41b to perform processing related to the progress of the game. Each part of the control circuit mounted on the control board 40 is controlled directly or indirectly. The ROM 41b stores fixed data such as programs executed by the CPU 41a and various tables. The RAM 41c is used as a work area when the CPU 41a executes a program. The I / O port 41d inputs / outputs a control signal to / from each circuit connected via a signal input / output terminal included in the main control unit 41.

  The main control unit 41 includes a signal input terminal DATA, and detection states of various switches connected to the game control board 40 are input to the input port via the signal input terminal DATA. The input states of these signal input terminals DATA are monitored by the CPU 41a, and the CPU 41a executes a basic process that shifts in stages according to the input states of the signal input terminals DATA, that is, the detection states of various switches.

  In addition, the CPU 41a has an interrupt function as described above, and can execute an interrupt process by interrupting the basic process when an interrupt occurs. In this embodiment, four types of interrupts of interrupts 1 to 4 can be executed. For each interrupt, a counter mode (signal input from a trigger terminal CLK / TRG provided separately from the signal input terminal DATA) is provided. Can be selected and set between an interrupt mode that generates an external interrupt according to the number of times) and a timer mode (an interrupt mode that generates an internal interrupt according to the number of clock inputs of the CPU 41a).

  In the present embodiment, among the interrupts 1 to 4, interrupt 2 is set to the counter mode, interrupt 3 is set to the timer mode, and interrupts 1 and 4 are unused. The trigger terminal CLK / TRG is connected to the above-described power failure detection circuit 48, and the CPU 41a generates an interrupt 2 in response to the input of the voltage drop signal output from the power failure detection circuit 48, and the power failure described later. Interrupt processing (main) is executed. Further, the CPU 41a generates an interrupt 3 every time the number of clock inputs reaches a certain number, that is, every certain time interval (about 0.56 ms in this embodiment), and performs a timer interruption process (main) described later. Run. Moreover, although the interrupts 1 and 4 are set to unused, the interrupts 1 and 4 may generate | occur | produce by noise etc. For this reason, when interrupts 1 and 4 occur, the CPU 41a executes an unused interrupt process that immediately returns to the original process.

  The CPU 41a is set to prohibit other interrupts during execution of interrupt processing based on the occurrence of any one of interrupts 1 to 4, and a plurality of interrupts occurred simultaneously. In this case, interrupts to be executed with priority in the order of interrupts 2, 3, 1, 4 are set. In other words, when interrupt 2 and other interrupts occur simultaneously, interrupt 2 is prioritized and when interrupt 3 and interrupt 1 or 4 occur simultaneously, interrupt 3 is prioritized.

The random number generation circuit 42 defines a range of numerical values to be counted for each type of random number. In this embodiment, 0 to 16383 is defined as the range. The CPU 41a sends an instruction to the sampling circuit 43 in accordance with the processing to acquire the numerical value indicated by the random number generation circuit 42 as a random number (this function is hereinafter referred to as a hardware random number function). Random numbers for internal lottery, which will be described later, are not used as they are extracted by the hardware random number function, but are processed and used by software. Details thereof will be described in detail. The CPU 41a also has a function of updating a numerical value of a specific register by the above-described timer interrupt process (main), and acquiring the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function).

  The disconnection monitoring IC 50 monitors the electrical connection state between the game control board 40 and the inserted medal sensor 31 and the electrical connection state between the game control board 40 and the effect control board 90, and these connection states. If one of these is released, a disconnection flag indicating that these connection states have been released is stored in a storage unit such as an EEPROM (not shown) provided in the disconnection monitoring IC 50. . In response to the disconnection flag confirmation request from the CPU 41a, the disconnection monitoring IC 50 returns whether or not the disconnection flag is stored. At this time, the disconnection flag is cleared if it is stored in the storage unit.

  The disconnection monitoring IC 50 is also supplied with backup power in the event of a power failure. For example, unless the power failure state continues for 2 to 3 days, an electrical connection between the game control board 40 and the inserted medal sensor 31 is performed. Monitoring of the connection state and the electrical connection state between the game control board 40 and the effect control board 90 can be continued.

  The CPU 41a transmits various commands to the effect control board 90 via the I / O port 41d. A command transmitted from the game control board 40 to the effect control board 90 is sent in only one direction, and no command is sent from the effect control board 90 to the game control board 40. The transmission line of the command transmitted from the game control board 40 to the effect control board 90 is composed of a strobe (INT) signal line, a data transmission line, and a ground line, and is connected via the effect relay board 80. The game control board 40 and the effect control board 90 are not directly connected.

  The effect control board 90 is connected to the light receiving devices 57a and 57b constituting the touch panel described above, and the detection signals of the connected light receiving devices 57a and 57b are input.

  Electrical components such as a liquid crystal display 51 (see FIG. 1), a rendering effect LED 52, speakers 53 and 54, and the reel LED 55 described above are connected to the rendering control board 90, which is disposed on the front door 2b of the slot machine 1. These electric components are driven based on control by a sub-control unit 91 (described later) mounted on the effect control board 90. The effect control board 90 is connected to the light emitting devices 56a and 56b constituting the touch panel described above, and the light emitting devices 56a and 56b are based on control by a touch panel controller 99 described later mounted on the effect control board 90. To be driven.

Similar to the main control unit 41, the effect control board 90 includes a microcomputer having a CPU 91a, ROM 91b, RAM 91c, and I / O port 91d.

While performing, it controls each part of the control circuit mounted in the production | presentation control board 90 directly or indirectly.

  Similar to the CPU 41a of the main control unit 41, the CPU 91a has an interrupt function (including an interrupt prohibition function). An interrupt terminal (not shown) 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 command transmission lines. 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 reception buffer. The CPU 91a executes a timer 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.

  The interrupt terminal (not shown) of the CPU 91a is connected to the power interruption detection circuit 98 described above, and the CPU 91a generates an interrupt in response to the input of the voltage drop signal output from the power interruption detection circuit 98. Then, a power interruption interruption process (sub) described later is executed. Also, when an unused interrupt occurs in the CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

  Unlike the CPU 41a, the CPU 91a executes interrupt processing based on interrupts other than the interruption interrupt processing (sub) when an interrupt is generated based on the input of the strobe signal (INT). Even if it is in the middle, interrupt the corresponding process and execute the command reception interrupt process, and execute the command reception interrupt process with the highest priority even if other interrupts other than the power interruption interrupt process (sub) occur at the same time It is supposed to be. Note that interrupts other than interrupts based on the input of the strobe signal (INT) are prohibited during execution of interrupt processes other than the power interruption interrupt process (sub). On the other hand, in the interruption interrupt processing (sub), other interruption processing including command reception interruption processing is prohibited at all, and even if other interruptions occur at the same time, interruption interruption processing (Sub) is executed with the highest priority.

  The sub-control unit 91 is also supplied with backup power at the time of a power failure, and while the backup power is supplied, the CPU 91a performs a refresh operation so that the data stored in the RAM 91c is retained. It has become.

  Next, details of the wiring connection state between the game control board 40 and various game electronic components connected to the game control board 40 will be described with reference to FIG. FIG. 3 is a schematic diagram showing a wiring connection state between the game control board 40 and the game electronic components connected to the game control board 40.

  On the game control board 40, as described above, the single BET switch 5, the MAXBET switch 6, the start switch 7, the stop switches 8L, 8C, and 8R, the insertion medal sensor 31, the door opening detection switch 25, and the reel motors 32L and 32C. , 32R, reel sensors 33L, 33C, 33R, a hopper motor 34b, a payout sensor 34c, and an effect control board 90 are connected.

  As shown in FIG. 3, among these, one BET switch 5, MAXBET switch 6, start switch 7, stop switches 8L, 8C, 8R, insertion medal sensor 31, reel motors 32L, 32C, 32R, reel sensor 33L, The 33C and 33R, the hopper motor 34b, and the payout sensor 34c are electronic components that input and output signals related to the progress of the game to 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 game electronic components in accordance with 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 electronic component.

  These gaming electronic components are a first electronic 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 electronic components.

  Specifically, the single bet switch 5 and the MAXBET switch 6 that are operated when setting the bet number and the inserted medal sensor 31 that detects a medal inserted to set the bet number are the operation or the medal of the medal. This is a first electronic component that outputs a BET signal to the game control board 40 based on the detection. Since the main control unit 41 performs the betting number setting process based on the reception of the BET signal, the betting number cannot be set without these electronic components. That is, since the game cannot be started unless the bet number is set, the one-sheet BET switch 5, the MAXBET switch 6, and the inserted medal sensor 31 are electronic components for games necessary for the progress of the game.

  The start switch 7 that detects an operation for starting a game is a first electronic component that outputs a start signal to the game control board 40 based on the detection of the operation. Since the main control unit 41 performs a process for starting the game (reel rotation process or the like) based on the reception of the start signal, the game cannot be started without this electronic component. That is, the start switch 7 is a game electronic component necessary for the progress of the game.

  Stop switches 8L, 8C, and 8R that detect an operation for deriving the display results of the reels 2L, 2C, and 2R are first electronic components that output a stop signal to the game control board 40 based on the detection of the operation. is there. The main control unit 41 performs processing for deriving the display result by stopping the rotation of the corresponding reels 2L, 2C, and 2R based on the reception of the stop signal. The display result of cannot be derived. That is, the stop switches 8L, 8C, and 8R are game electronic components necessary for the progress of the game.

  The reel sensors 33L, 33C, and 33R that detect the rotation of the reels 2L, 2C, and 2R are first electronic components that output a detection signal for the reference position of the reel to the game control board 40. The main control unit 41 does not have this electronic component because it performs processing to stop rotation by grasping the positions of the symbols of the corresponding reels 2L, 2C, and 2R based on reception of the detection signal of the reference position of the reel. In addition, derivation of display results of each reel 2L, 2C, 2R, determination of winning, etc. cannot be performed. That is, the reel sensors 33L, 33C, and 33R are game electronic components necessary for the progress of the game.

The payout sensor 34c that detects medals to be paid out as a result of winning is a first electronic component that outputs a medal payout signal to the game control board 40 based on the detection of the medals. The main control unit 41 performs a payout process for paying out the number of medals according to the generated prize based on the reception of the payout medal detection signal. Therefore, the number of medals according to the number of prizes generated without this electronic component. Cannot be paid out. That is, the payout sensor 34c is a gaming electronic component necessary for the progress of the game.

  The reel motors 32L, 32C, and 32R that rotate the reels 2L, 2C, and 2R are second electronic components to which a drive signal output from the game control board 40 is input. The reel motors 32L, 32C, and 32R rotate the reels 2L, 2C, and 2R based on the input of the drive signal output from the game control board 40 and start the symbol variation display. Even if the reels 2L, 2C, and 2R are not actually rotated based on the above, the main control unit 41 receives the signals from the reel sensors 33L, 33C, and 33R after outputting the reel drive signals. The game can be controlled to proceed as the reel rotates. However, the timing at which signals are input to the game control board 40 from the reel sensors 33L, 33C, and 33R is an error unless the reel drive signal is output. In order to measure the output timing of the signal based on the detection of the rotation of the reel, a reel drive signal is required. That is, the reel motors 32L, 32C, and 32R are game electronic components necessary for the progress of the game.

  The hopper motor 34b that drives the hopper tank that pays out medals is a second electronic component that receives a drive signal output from the game control board 40 in response to a winning. The hopper motor 34b performs a medal payout operation based on the input of a drive signal output from the game control board 40, but even if the medal payout operation is not actually performed based on the signal input. The main control unit 41 can control to advance the game on the assumption that medals have been paid out by inputting a signal from the payout sensor 34c after outputting a drive signal of the hopper motor 34b. However, the timing at which a signal is input from the payout sensor 34c to the game control board 40 is an error unless the drive signal of the hopper motor 34b is output. In order to measure the output timing of the signal based on the detection of this, a drive signal for the hopper motor 34b is required. That is, the hopper motor 34b is a gaming electronic component necessary for the progress of the game.

  The gaming electronic parts and the door opening detection switch 25 are basically electronic parts that are continuously used in common with a plurality of models, and there is no opportunity to remove and replace them from the main body unless a malfunction or the like occurs. Since there are few, it is fixed to the predetermined part of the main body of the slot machine. 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. That is, when the gaming control board 40 is removed, it is necessary to release the connection between the gaming electronic parts and the door opening detection switch 25, so that the gaming electronic parts and door opening detection switch 25 and the gaming control board 40 are relayed. In addition to being connected via the boards, the boards and the boards are connected to the gaming electronic components and the door opening detection switch 25 via cables. The cable and the board are electrically connected by connecting a cable side connector provided at an end of the cable and a board side connector electrically connected to the wiring pattern of the board.

  More specifically, the single BET switch 5, the MAXBET switch 6, the start switch 7, the stop switches 8L, 8C, and 8R, the insertion medal sensor 31, and the door opening detection switch 25 are played via the operation unit relay board 110.

  In this embodiment, the wiring is extended from each electronic component without using a connector, but may be connected to the wiring through a connector.

  As described above, each board and each cable includes board-side connectors 620a to 620d, 621a to 621d, 622a to 622k, 622p, 622q, and 623p provided on the board side, and cable-side connectors 610a to 623p provided on the cable side. 610d, 611a to 611d, 612a to 612k, 612p, 612q, and 613p are wired and connected via a pair of connectors (male connector and female connector), and by removing the cable side connector from the board side connector The wiring connection can be released. In particular, the game control board 40, the operation unit relay board 110, the reel relay board 120, the power board 101, and the effect control board 90 are attached to predetermined positions on the casing or front door of the slot machine 1, so that the board side Since the cable side connector can be easily removed from the connector, the game control board 40 and the effect control board 90 can be easily replaced.

First, the first electronic component will be described in detail. One of the BET switch 5, the MAXBET switch 6, or the connector of a cable provided between the inserted medal sensor 31 and the game control board 40 is driven into a connector. the connector is connected, the BET signal to the game controller board 40 from the appliance narrowing Chi ball striking is outputted illegally, there is a possibility that the betting amount is set to the betting amount setting operation is not performed. When a connector of a driving tool is connected to one of the connectors of a cable provided between the start switch 7 and the game control board 40, and a start signal is illegally output from the driving tool to the game control board 40 There is a possibility that the game is started without performing the game start operation. The connector of the driving tool is connected to one of the connectors of the cable provided between the stop switches 8L, 8C, 8R and the game control board 40, and the stop signal is illegally transmitted from the driving tool to the game control board 40. If output, the rotation of the reel may be stopped without performing a stop operation. The connector of the driving tool is connected to one of the connectors of the cable provided between the reel sensors 33L, 33C, 33R and the game control board 40, and the reel rotation signal is illegal from the driving tool to the game control board 40. Is output to the reels 2L, 2C, and 2R, the result of the display may be derived, and the winning determination may be performed. The connector of the driving tool is connected to one of the connectors of the cable provided between the payout sensor 34c and the game control board 40, and a medal payout signal is illegally output from the driving tool to the game control board 40. There is a possibility that the medals are counted without paying out medals.

The second electronic component will be described in detail. The game control board 40 is released by disconnecting one of the connectors of the cable provided between the reel motors 32L, 32C, 32R and the game control board 40. When the driving signal output from the game control board 40 can be acquired by the driving tool, the timing at which the driving signal of the reel is output from the game control board 40 can be specified on the driving tool side, so game control is originally performed from the reel sensors 33L, 33C, 33R. There is a possibility that the reel rotation detection signal input to the substrate 40 may be output from the driving tool at an appropriate timing after the reel rotation. In addition, the drive signal output from the game control board 40 after the connection at any of the connectors of the cable provided between the hopper motor 34b and the game control board 40 is released can be obtained by a driving tool or the like. Then, since the timing at which the driving signal of the hopper tank is output from the game control board 40 can be specified on the driving instrument side, the payout medal detection signal originally input from the payout sensor 34c to the game control board 40 is sent from the driving tool to the hopper. There is a risk of output at an appropriate timing after the tank is driven.

As described above, when a signal output from the first electronic component according to the progress of the game and originally input to the game control board 40 is output from the driving tool, the main control unit 41 receives the signal. The game can be controlled based on the game, and a signal that is output from the game control board 40 according to the progress of the game and is originally input to the second electronic component is input to the driving tool. In this case, on the driving instrument side, the main control unit 41 can specify the output timing of the signal output after driving the reel motor or the hopper motor, and when a new signal is input to the game control board 40 based on this. Since the main control unit 41 can perform control to advance the game based on the reception of the signal, an illegal act such as automatically progressing the game can be performed. There is a possibility to be applied. Therefore, in this embodiment, various measures are taken to prevent illegal acts caused by the connection of the driving tool.

  Further, when the connection at any of the connectors of the cable provided between the door opening detection switch 25 and the game control board 40 is released, the game is notified when the front door 2b is opened. Since the main control unit 41 mounted on the control board cannot be detected and the door opening notification and the door opening signal are not output, the discovery is delayed even if the front door 2b is opened and an illegal act is performed. There is a risk that. Therefore, in this embodiment, measures are taken to make it difficult to release the connection between the connectors provided between the door opening detection switch 25 and the game control board 40.

  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 a regular bonus is described later, a BB signal indicating that the gaming state is a big bonus described later, a door opening signal indicating that the front door 2b is opened, and a setting change mode described later. A setting change signal indicating transition, a throwing error signal indicating a medal selector abnormality, and a payout error signal indicating a hopper unit (not shown) abnormality are output.

  In this embodiment, there is no challenge time (a gaming state in which the number of sliding pieces on the reel is limited, but winning is allowed for all small roles) or a challenge bonus with a high probability of challenge time. However, in order to make common with the slot machines equipped with these gaming states, in addition to the signal lines for outputting the above signals, the gaming state is a challenge between the gaming control board 40 and the external output board 1000. A signal line for outputting a CT signal indicating that the time is in progress and a CB signal indicating that the gaming state is in the challenge bonus is connected, and a signal line for error output that may be expanded in the future is connected. Has been.

And the connection between the board-side connector 621a of the operation unit relay board 110 and the connection between the board-side connector 622g of the operation part relay board 110 and the cable-side connector 612g of the cable 601g are restricted from being released from each other. The connection between the board side connector 620a and the cable side connector 610a is restricted by the connector restricting member 500, the connection between the cable side connector 611a and the board side connector 621a, and the connection between the board side connector 622g and the cable side connector 612g. The release of the connection is regulated by the connector regulating member 650.

  Further, by restricting the release of the connector connection between the game control board 40 and the door opening detection switch 25, it is difficult to release the connection between the game control board 40 and the door opening detection switch 25. Specifically, the connector connection between the game control board 40 and the door opening detection switch 25, that is, the connection between the board side connector 620a of the game control board 40 and the cable side connector 610a of the cable 600a, the cable side connector of the cable 600a. The connection between the connectors 611a and 621a of the operation unit relay board 110 and the connection of the board side connector 622q of the operation unit relay board 110 and the cable side connector 612q of the cable 601q is restricted. . The connection between the board side connector 620a and the cable side connector 610a is restricted by the connector restricting member 500, the connection between the cable side connector 611a and the board side connector 621a, and the connection between the board side connector 622q and the cable side connector 612q. The release of the connection is regulated by the connector regulating member 650.

  Further, by restricting the release of the connector connection between the game control board 40 and the effect control board 90, it is difficult to release the connection between the game control board 40 and the effect control board 90. Specifically, the connector connection between the game control board 40 and the effect control board 90, that is, the connection between the board side connector 620d of the game control board 40 and the cable side connector 610d of the cable 600d, the cable side connector 611d of the cable 600d. And the board side connector 621d of the production relay board 80, the board side connector 622p of the production relay board 80 and the cable side connector 612p of the cable 601p, the cable side connector 613p of the cable 601p and the board side of the production control board 90 The connection with the connector 623p is restricted from releasing the connection between these connectors. The connection between the board-side connector 620d and the cable-side connector 610d is restricted by the connector restricting member 500b, the connection between the cable-side connector 611d and the board-side connector 621d, and the connection between the board-side connector 622d and the cable-side connector 612d. Connection and connection between the cable-side connector 613p and the board-side connector 623p are restricted by a connector restricting member (not shown).

  These connector restricting members are configured to be able to restrict the removal of the cable side connector from the board side connectors connected to each other, and the connection release restricting state that makes the release impossible unless the release restricting part related to the connection with the connector is destroyed. As long as it is configured to leave a trace when the connection release restriction state is released, its form is arbitrary and can be variously changed.

  Specifically, for example, it may be a cover body that is formed separately from the board-side connector and the cable-side connector and that can be attached and removed in a connected state to restrict the connector from being removed. Alternatively, it may be a locking portion that is provided on at least one of the board-side connector and the cable-side connector and that cannot be detached from each other when the connectors are connected to each other, or the board-side connector is mounted. In a restricting portion or the like that is provided in a substrate storage case or the like that can store a substrate to be connected, and that forms a connection release restriction state that restricts connector removal when the substrate is stored in the substrate storage case and sealed. It may be an adhesive or the like that bonds the connectors connected to each other.

The connecting portion 287 is cut (see FIG. 13A).

  The special screw 280d may be made of metal, but may be made of synthetic resin so that the head 285 and the upper member 284 can be easily separated.

  Accordingly, in this state, the fixing portion is fixed by the special screw 280d, and the upper member 284 separated from the special screw 280d remains in the internal space of the mounting sealing piece 231d. Since the upper surface of the mounting sealing piece 231d is covered with the cap 290d, the upper member 284 is confined in the internal space of the mounting sealing piece 231d (see FIG. 13A).

  Then, even if a tool is inserted through the opening 291 provided in the cap 290d in order to remove the fixing that fixes the fixing portion, the tool cannot reach the head 285. That is, it is difficult to release the sticking even if the sticking by the special screw 280d is illegally released.

  Here, the case where the fixed portion is fixed by the special screw 280d to realize the mounting state has been described, but the fixed portion composed of the mounting sealing pieces 231a to 231c and the fixing member 255 is fixed by the special screws 280a to 280c. Also in the case of realizing the mounting state by adhering, and in the case of realizing the sealing state by adhering the adhering portion composed of the upper sealing piece 230 and the lower sealing piece 215, the mounting sealing piece 231d by the special screw 280d. The process is executed in the same manner as in the case of fixing the fixing portion consisting of the fixing member 255.

  Returning to FIG. 5, engagement pieces 245 and 245 that can be engaged with the engagement grooves 210 and 210 of the lower case 201 protrude from the end portions on the side of the side wall 202 c on the outer surfaces of the side walls 202 b and 202 b of the upper case 202. ing. The engaging pieces 245 and 245 are linearly extended in the longitudinal direction in parallel to the lower end side of the side wall 202c, and are inserted into the engaging grooves 210 and 210 from one end openings, thereby lower case 201. The detachment of the upper case 202 is restricted (see FIG. 6).

  Further, the other short side wall 202d of the upper case 202 has a locking piece 232 inserted through and locked into locking holes 211, 211 formed in the other short side wall 201c of the lower case 201. 232 protrudes outward.

  The substrate case 200 configured as described above is configured so that the upper surface of the bottom plate 201a of the lower case 201 and the back surface of the upper surface plate 202a of the upper case 202 face each other as shown by a one-dot chain line in FIG. The side walls 202b, 202c of the upper case 202 protrude from the bottom plate 201a of the lower case 201 so that one end of the upper case 202 protrudes from an opening portion of the short side opposite to the side wall 201c of the 201, that is, one side without the side wall. In this state, by sliding in the longitudinal direction toward the inside of the lower case 201 (left side in FIG. 4), the locking pieces 232 and 232 are inserted into the locking holes 211 and 211 on one short side. On the other short side, the lower fixing pieces 213 and 213 are inserted into the insertion holes 204 and 204 and arranged on the upper surface side of the upper fixing pieces 205 and 205. Engaging piece 245, 245 is engaged in the engaging groove 210, 210, these locking action, so that the withdrawal of the upper case 202 from the lower case 201, that is floating is restricted.

  Concave portions 202g and 202h are formed in the step portions 202e and 202f on both short sides of the upper case 202, respectively, and the bottom surface of the concave portion 202g of the step portion 202e is on the back side of the upper case 202 as will be described later. An insertion hole 246b through which the board-side connector 620d can be inserted is formed at a position corresponding to the board-side connector 620d of the game control board 40 attached to the game control board 40. An insertion hole 246a through which the board-side connector 620a can be inserted is formed at a location corresponding to the board-side connector 620a.

  As shown in FIG. 4, the game control board 40 is attached to the back side of the upper case 202 configured in this way by fastening four corners with four attachment screws 235. The game control board 40 is attached to the back surface side of the upper case 202 with the mounting surface 40a (mounting surface) on which electronic components or the like are mounted (mounted) facing the back surface of the upper case 202, and is attached. In particular, as shown in FIG. 9, the back surface, which is the opposite side surface of the mounting surface 40 a, is accommodated so as to be positioned above the lower ends of the side walls 202 b to 202 d.

  Further, a board cover 240 that covers the back surface of the game control board 40 is attached to the back side of the game control board 40. The substrate cover 240 includes a cover plate 240a made of a transparent synthetic resin and ribs 240b provided on one long side portion and two short side portions of the cover plate 240a. The board cover 240 is formed in a rectangular shape with a long side formed substantially the same size as the game control board 40 and a short side, and a short side shorter than the long side. The end portion, that is, the end portion on the fixing portion side where the upper sealing piece 230 and the attachment sealing pieces 231a to 231d are formed is formed in a size that can be covered.

  The board cover 240 of this embodiment is formed in a size that can cover only the end of the back side of the game control board 40 on the fixing part side, that is, a part of the back side. You may form in the magnitude | size which can coat | cover the whole region.

  As shown in FIG. 9, a recess 241 a having an attachment hole 241 to which the attachment screw 235 is attached is formed on the back surface of the substrate cover 240 so that the head of the attachment screw 235 can be accommodated. Further, on the pair of short sides, positioning pieces 242 and 242 that are fitted into positioning recesses 243 and 243 (see FIG. 6) formed on the lower ends of the side walls 202b and 202b of the upper case 202 are projected outward. At the time of attachment, the attachment position of the substrate cover 240 with respect to the upper case 202 is determined.

  The board cover 240 is attached so as to cover the end portion on the fixing part side on the back surface of the game control board 40 attached to the back surface of the upper case 202, and in the attached state, the back surface is the side wall of the upper case 202. It becomes substantially flush with the lower end surfaces of 202b to 202d. Therefore, as described later, in a sealed state in which the upper surface of the lower case 201 is closed by the upper case 202, it is disposed in a state of being sandwiched from above and below by the bottom plate 201a of the lower case 201 and the game control board 40. Since the mounting screw 235 is mounted with the head covered with the bottom plate 201a, the substrate cover 240 is mounted on the substrate unless the sealed state is released and the upper case 202 is opened unless the substrate case 200 is partially destroyed. The case 200 cannot be detached.

  The board cover 240 is attached to the upper case 202 using the mounting screw 235 for attaching the game control board 40 to the back side of the upper case 202. However, the board cover 240 is attached with a screw or the like separate from the mounting screw 235. Alternatively, it may be attached to the game control board 40.

  The attachment base 250 is an attachment member that constitutes an attachment portion for attaching and attaching the substrate case 200 to a housing (not shown) that forms the main body of the slot machine 1. The mounting base 250 is made of synthetic resin, and as shown in FIGS. 11 and 12, a bottom plate 250a formed in a substantially rectangular shape larger than the bottom plate 201a of the lower case 201, and two of the peripheral edges of the bottom plate 250a. The side walls 250b and 250b erected along the long edge side and the side walls 250c and 250d erected along the short edge side are formed in a rectangular parallelepiped shape whose upper surface is opened. A notch 250e is formed at the center of one side wall 250d, and a pair of guides 254 and 254 are provided from the notch 250e in the bottom plate 250a toward the center. Guide grooves 254a and 254a into which engaging portions 257 and 257 formed at both ends of a fixing member 255 described later are fitted are formed on the opposing surfaces of the guides 254 and 254, respectively. In addition, screw holes 252 are formed at a plurality of locations on the bottom plate 250 a of the mounting base 250.

The fixing member 255 is made of synthetic resin, and has four screw holes 256 formed on the upper surface, and the lower ends of the cylindrical portions of the mounting sealing pieces 231a to 231d are fitted around the screw holes 256. A positioning recess 256a is formed. Further, as shown in FIG. 13A, a metal plate 255 a having a hole portion 255 b provided at a position corresponding to the screw hole 256 is embedded in the fixing member 255. The diameter of the hole portion 255b is slightly smaller than the diameter of the screw portion 283 (specifically, the diameter immediately above and below the constricted portion 286) of the special screws 280a to 280d, and is slightly smaller than the lower end portion of the constricted portion 286. The diameter of the constricted portion 286 formed in the middle of H.283 is almost the same.

  As shown in FIGS. 11 to 13, locking portions 257 and 257 are formed at both ends of the fixing member 255, and the locking portions 257 and 257 are formed on the guides 254 and 254 of the mounting base 250. It is attached to the attachment base 250 by being inserted into the guide grooves 254a and 254a. Further, a locking hole 258 a for locking a locking claw 258 formed at the tip of an elastic locking piece formed on the bottom plate 250 a is formed on the inner side of the fixing member 255, and the mounting base 250 has a locking hole 258 a. In the attached state, the latching claw 258 is latched in the latching hole 258a, and detachment is regulated.

  As described above, the fixing member 255 is detachably provided to the mounting base 250. Therefore, when sealing is performed a plurality of times as described later, it can be easily replaced with a new fixing member 255. It is like that. A fitting hole 260 into which the cylindrical portion 215a of the lower sealing piece 215 is fitted is formed on one side of the attachment position of the fixing member 255 on the bottom plate 250a.

  At one end of the long side walls 250b and 250b, bulging portions 261 and 261 bulging outward are formed, and can accommodate a connector regulating member 500 attached to the board case 200 as will be described later. It is said. In addition, a locking portion 262 that locks to the attached substrate case 200 to prevent the side wall 250b from projecting inwardly protrudes inward from the upper end of the side wall 250b. It is installed.

  A seal adhering portion 264 for adhering a seal seal 263 for sealing the attachment base 250 and the substrate case 200 attached to the attachment base 250 is formed at the center position in the longitudinal direction of the other side wall 250b. ing. As shown in the enlarged view of FIG. 12, the seal sticking portion 264 includes a vertical plate 264a extending upward from the upper end of the side wall 250b and a horizontal plate 264b formed by bending outward from the upper end of the vertical plate 264a. And the upper surface of the horizontal plate 264b is flush with the upper surface of the substrate case 200 attached to the mounting base 250, that is, the upper surface of the upper surface plate 202a of the upper case 202. Is formed.

  Since a gap corresponding to the thickness of the side wall 201b of the lower case 201 is formed between the inner surface of the vertical plate 264a and the outer surface of the side wall 202b of the upper case 202, a sealing seal is formed with a plate-like spacer 265 inserted into the gap. 263 can be adhered to the outer surface of the upper case 202 from the upper surface of the upper case 202 to the outer surface of the seal attaching portion 264.

  On the short side wall 250c, mounting locking holes 266 and 266 for locking the locking pieces 232 and 232 of the upper case 202 in the substrate case 200 are formed.

  As shown in FIGS. 11 and 12, the connector restricting member 500 is attached to the board case 200 and the cable side attached to the board-side connector 620a. A connector cover 520 that covers a part of the connector 610a, and the attachment side member 510 is attached to the board case 200, and the connector cover 520 is attached to the cable side connector 610a from the board side connector 620a. Removal is regulated.

  The attachment-side member 510 is made of a transparent synthetic resin and is formed in a shape along the surface shapes of the lower case 201 and the upper case 202 that constitute the substrate case 200. Specifically, the attachment side member 510 is attached to the short side where the locking piece 232 of the upper case 202 is provided, and the shape thereof is the step portion 202f in the upper case 202 when attached to the board case 200. Standing piece that stands up from both ends of a base piece 510a that is in contact with the bottom surface of the recess 202h and that has a notch 512 that allows the cable-side connector 610a to escape and a cylindrical locking hole 513 that has a locking hole 513a inside. Upper pieces 510c and 510c that contact the upper surfaces of both end portions of the stepped portion 202f in the upper case 202 are extended through 510b and 510b, and are further engaged through side pieces 510d and 510d depending from both ends of the upper pieces 510c and 510c. The stoppers 257 and 257 have a shape extending inward, and the base piece 51 of the attachment side member 510 is attached to the board case 200. a, upper piece 510c, the opposing surface is adapted to abut respectively on the bottom surface of the top surface and the recess 202h of the stepped portion 202f of the upper casing 202 relative to the board case 200 of 510c.

  As shown in FIG. 15, a locking groove 514 is provided on the inner surface of the locking hole 513 in the locking hole portion 513 at a position opposed to the center from the lower end of the locking hole 513 a. Yes. The locking groove 514 has a substantially L shape including a shallow groove portion 514a having a shallow depth from the lower end of the locking hole 513a and a deep groove portion 514b deeper than the shallow groove portion 514a, and the shallow groove portion 514a of the opposing locking grooves 514 and 514. 514a and deep groove portions 514b and 514b are formed at positions facing each other across the center. That is, the locking grooves 514 and 514 are formed symmetrically with respect to the center.

  The connector cover 520 is made of a transparent synthetic resin and, as shown in FIGS. 11 and 12, is a cable connected to the board-side connector 620a when attached to the attachment-side member 510 attached to the board case 200. A covering portion 521 having a substantially U-shaped cross-sectional view covering a part of the side connector 610a is formed, and one side surface 521a of the side surface in the longitudinal direction of the covering portion 521 is formed with a locking hole portion 513 in the attachment side member 510. A locking cylinder 522 having substantially the same diameter as the inner periphery of the locking hole 513a is provided via the connection piece 522a.

  The lower end of one side surface 521a of the covering portion 521 contacts the upper surface of the base piece 510a when attached to the attachment-side member 510, and ribs 521b and 521b are provided on the back surface of the side surface 521a. The lower surface of 521b is also in contact with the upper surface of the base piece 510a.

  As shown in FIG. 15, the locking cylinder 522 has an outward locking claw 523a formed at the tip at a position opposed to the center, and engagement portions 523 and 523 that are elastically deformable inward. It has been. The engaging portions 523 and 523 have engaging holes 523a and 523a when the connector cover 520 is attached to the attachment-side member 510 with the cable-side connector 610a connected to the board-side connector 620a. The locking grooves 514 and 514 formed in the 513a are provided at positions that engage with the shallow groove portions 514a and 514a.

  Next, a sealing state of the lower case 201 and the upper case 202, an attachment state of the connector restricting member 500 to the substrate case 200, and an attachment state of the substrate case 200 to the housing will be described.

  First, the case where the game control board 40 is accommodated in the lower case 201 and the upper case 202 constituting the board case 200 to be in a sealed state will be described.

First, as shown in FIG. 4, the game control board 40 is attached to the back side of the upper case 202 via the attachment screw 235. At this time, with the mounting surface 40a of the game control board 40 facing the back surface of the upper case 202, the game control board 40 is fitted and positioned in the upper case 202, and in this state, the back surface of the game control board 40 is placed. The substrate cover 240 is arranged on the side of the upper sealing piece 230 and the attachment sealing pieces 231a to 231d on the side. The two corners on the locking piece 232 side are attached with mounting screws 235, and the two corners on the upper sealing piece 230 and the mounting sealing pieces 231 a to 231 d side are attached with the mounting screws 235 from the back side of the substrate cover 240. It is attached to the attachment hole 241 and attached to the screw hole (not shown) of the upper case 202 together with the game control board 40.

  Thus, even if the upper case 202 is illegally opened, the upper case 202 is illegally opened by housing the game control board 40 so that the mounting surface 40a is covered on the back side of the upper case 202. Unless the game control board 40 is removed from 202, the electronic parts mounted on the mounting surface 40a cannot be fraudulently performed.

  Next, the back side of the game control board 40 and the board cover 240 attached to the back side of the upper case 202 is opposed to the upper surface of the bottom plate 201a of the lower case 201, and the short side without the side wall opposite to the side wall 201c of the lower case 201 The side walls 202b and 202c of the upper case 202 are brought into contact with the bottom plate 201a of the lower case 201 so that one end of the upper case 202 protrudes from the opening of the upper case 202. Slide in the longitudinal direction (toward the left side in FIG. 4). At this time, on one short side, the locking pieces 232 and 232 are inserted and locked from the inside into the locking holes 211 and 211, and on the other short side, the lower fixing pieces 213 and 213 are inserted into the insertion holes 204, 204 is inserted in the upper surface of the upper fixing pieces 205 and 205, and the engaging pieces 245 and 245 are engaged in the engaging grooves 210 and 210.

  That is, the locking pieces 232 and 232 and the locking holes 211 and 211, the lower fixing pieces 213 and 213, and the insertion holes 204 and 204, and the engaging grooves 210 and 210 and the engaging pieces 245 and 245 are formed in the lower case. A slide movement guide means for sliding and guiding the upper case 202 relative to 201 is configured.

  When the engagement pieces 245 and 245 come into contact with the end portions of the engagement grooves 210 and 210 and the sliding movement is restricted, the position of the upper case 202 with respect to the lower case 201 is determined, that is, the lower case 201 and the upper case In the closed state (locked state) in which 202 is aligned, it becomes a state in which sealing described later is possible. As described above, in the substrate case 200 of this embodiment, when the upper case 202 is not slid along the bottom plate 201a of the lower case 201, the upper case 202 is locked or released from the locked state with respect to the lower case 201. In other words, the engagement of the upper case 202 from the lower case 201, that is, the lifting, is effectively restricted by the locking action.

  Further, in the aligned state, the upper sealing piece 230 is disposed to face the lower sealing piece 215, and the upper fixing pieces 205 and 205 are opposed to the upper surface side of the lower fixing pieces 213 and 213. Be placed.

  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 upper fixing pieces 205 and 205 and the lower fixing pieces 213 and 213 which are special fixing portions are used. Are shipped after they are fixed (caulked) in a special sealed state.

  Specifically, the upper fixing pieces 205 and 205 and the lower fixing pieces 213 and 213 are ultrasonically welded using a welding apparatus (not shown). As shown in FIG. 7, in the state where the lower fixing piece 213 is arranged on the upper surface side of the upper fixing piece 205, the flat upper surface of the upper fixing piece 205 and the flat lower surface of the lower fixing piece 213 are mutually connected. Opposing and abutting. In this state, with the upper fixing piece 205 placed on the base of a welding device (not shown), the lower fixing piece 213 is pressed from the upper surface by an instrument such as a horn (not shown) to be ultrasonically vibrated. As a result, the flat upper surface of the upper fixing piece 205 and the flat lower surface of the lower fixing piece 213 which are in contact with each other are cured after being melted and deformed, and as shown in FIG. Are welded and integrated with each other.

  That is, the upper fixing piece 205 and the lower fixing piece 213 and a welding device such as a horn constitute the first assembling and fixing means of the present invention. In addition, after welding, an instrument such as a horn of a welding apparatus for fixing the upper fixing piece 205 and the lower fixing piece 213 does not remain in the special fixing portion.

  Air bubbles generated between the upper surface of the upper fixing piece 205 and the lower surface of the lower fixing piece 213 during ultrasonic welding are accommodated in an annular annular groove 214 formed in the center of the lower surface of the lower fixing piece 213. This effectively increases the adhesion around the annular groove 214 without applying a pressure higher than a predetermined pressure. Accordingly, the upper fixing piece 205 and the lower fixing piece 213 are difficult to peel off, and a tool is provided between the upper surface of the upper fixing piece 205 and the lower surface of the lower fixing piece 213 from the side surfaces of the upper fixing piece 205 and the lower fixing piece 213. It becomes difficult to insert etc.

  As described above, the upper surface of the upper fixing piece 205 and the lower surface of the lower fixing piece 213 are melt-deformed and fixed (welded) to be integrated with each other. Since the upper fixing piece 205 and the lower fixing piece 213 are fixed in this manner, the sliding movement of the upper case 202 with respect to the lower case 201 is restricted, so that the locked state of the upper case 202 with respect to the lower case 201 is released. Can not do. That is, a special sealing state is formed in which the upper case 202 cannot be opened unless the fixed state between the upper fixed piece 205 and the lower fixed piece 213 is released.

  Here, for example, when the upper fixing piece 205 and the lower fixing piece 213 are peeled off by forcibly sliding the upper case 202 with respect to the lower case 201 in the unlocking direction, the opposing surfaces melt. Therefore, both the upper surface of the upper fixing piece 205 and the lower surface of the lower fixing piece 213, that is, both the lower case 201 and the upper case 202 leave scratches and deformation marks. It can be surely found that it may have been opened.

  Further, since the side portion between the opposing surfaces of the upper fixing piece 205 and the lower fixing piece 213 is covered with the protective piece 203, the cutter is laterally interposed between the opposing surfaces of the upper fixing piece 205 and the lower fixing piece 213. Since it becomes difficult to insert, etc., it becomes difficult to peel off.

Further, on the side of the upper fixing piece 205, by a pair of vertical pieces 203a facing the vertical direction, 203 a are disposed, a lower fixing piece 213 and the upper fixed piece 205 that is welded to each other as described below When the lower fixing piece 213 and the upper fixing piece 205 are to be cut at the root, that is, along the outer surface of the side wall 202c, the vertical piece projecting from the outer surface of the side wall 202c. since 203a, 203 a is in the way, the cutting is difficult by these protective strips 203.

  Further, the upper case 202 has a structure that cannot be detached from the lower case 201 unless the upper case 202 is slid in the unlocking direction with respect to the lower case 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 upper case 202 is detached from the lower case 201, and is locked in a state in which the slide movement guide means guides the slide movement. Since the upper fixed piece 205 and the lower fixed piece 213 cannot be separated so as to be separated toward each other in the locked state, the upper fixed piece 205 and the lower fixed piece 213 can be separated from each other. It is extremely difficult to peel off.

  Further, even when two substrate cases of the same type as the substrate case 200 are obtained as in the prior art, both of the lower case 201 and the upper case 202 remain scratched when the upper case 202 is opened. Since the case 201 and the upper case 202 cannot be obtained, it is extremely difficult to illegally configure the new substrate case 200.

  As described above, the upper fixed piece 205 and the lower fixed piece 213 are welded (fixed) to each other, so that the sliding movement of the upper case 202 with respect to the lower case 201 is restricted. That is, in the state where the locking pieces 232 and 232 formed on one short side of the upper case 202 are locked to the locking holes 211 and 211 of the lower case 201, A special sealing state in which the upper surface of the lower case 201 is closed by the upper case 202 is configured by the fixing pieces 213 being fixed. Since this special sealing state cannot be released unless both the upper fixing piece 205 of the upper case 202 and the fixing part of the lower fixing piece 213 of the lower case 201 are cut (broken), the upper case 202 is opened. In such a case, the trace, that is, the trace that a part of the board case 200 is destroyed remains without fail, and this may cause some illegal acts on the game control board 40 housed in the board case 200. It becomes possible to discover that there is.

  In this embodiment, when the lower case 201 and the upper case 202 are aligned at the closed position, the lower surface of the upper fixing piece 205 and the upper surface of the lower fixing piece 213 are in contact with each other. The lower surface of the upper fixing piece 205 and the upper surface of the lower fixing piece 213 may be arranged apart from each other as long as they are arranged so as to be welded to each other. In this case, for example, spot welding or the like in which a boss (not shown) formed at the tip of the horn is pushed down to the lower upper fixing piece 205 while the upper lower fixing piece 213 is dissolved can be applied.

  In the substrate case 200 configured to be opened and closed by sliding with respect to the lower case 201 as described above, the side wall 202c of the upper case 202 is particularly sealed as shown in FIG. Since the lower end surface is in contact with the upper surface of the bottom plate 201a of the lower case 201, that is, there is no stepped portion or the like between the lower end surface of the side wall 202c and the upper surface of the bottom plate 201a of the lower case 201. Although it may be easy to insert a tool or the like, the board cover 240 is obstructed even if foreign matter such as a wire enters the inside because the side wall 202c side of the back surface of the game control board 40 is covered with the board cover 240. As a result, it becomes difficult to allow the wire or the like to enter further, and the approach to the mounting surface 40a is effectively regulated. They are possible to prevent misconduct be input efficiently.

  Next, the case where the board | substrate case 200 which made the game control board 40 the sealing state attaches the connector control member 500 in a game store etc. is demonstrated.

  As shown in FIG. 11, the attachment-side member 510 is elastically deformed on both side pieces 510 d and 510 d outward and attached to the stepped portion 202 f of the upper case 202. Then, by releasing the elastic deformation, the locking piece 511 is attached by being engaged with the engagement grooves 212 and 212 on the back surface of the lower case 201. At this time, the base piece 510a and the upper pieces 510c and 510c of the attachment side member 510 are in contact with the upper surface of the stepped portion 202f and the bottom surface of the recessed portion 202h of the upper case 202, respectively, and the notch 512 provided in the base piece 510a The board-side connector 620a of the game control board 40 accommodated in the board case 200 is connected to the inside of the board case 200 through the notch 512 and the insertion hole 234a, which coincides with the insertion hole 234a provided in the recess 202h of the upper case 202. To be exposed to the outside.

  Next, the mounting screw 259 is screwed into the housing side wall through the screw hole 252 of the mounting base 250 to fix the mounting base 250 to the housing, and the locking portions 257 and 257 of the fixing member 255 are fixed. The fixing member 255 is mounted on the mounting base 250 by fitting into the guide grooves 254 a and 254 a of the mounting base 250.

  Next, a situation where the board case 200 to which the attachment side member 510 is attached is assembled to the attachment base 250 provided on the inner surface of the housing will be described.

  Specifically, as shown in FIG. 11, the locking pieces 232 and 232 projecting to one end side of the substrate case 200, specifically the locking holes 211 and 211 of the lower case 201, are inserted from the inside and are inserted into the side wall 201 c. With the tips of the locking pieces 232 and 232 protruding outward inserted into the locking holes 266 and 266 of the mounting base 250 and locked, the other end side of the board case 200 is connected to the locking pieces 232 and 232 side. Around the bottom plate 250a of the mounting base 250.

  Then, as shown in FIG. 12, the board case 200 is accommodated inside the side walls 250 b, 250 c, 250 d of the mounting base 250. In this state, the columnar portion 215a continuously provided on the lower surface of the lower sealing piece 215 of the lower case 201 is fitted into the fitting hole 260 formed in the mounting base 250, and the upper sealing piece of the upper case 202 is fitted. 230 and the lower sealing piece 215 of the lower case 201 are arranged to face the fitting hole 260, and the lower ends of the cylindrical portions of the four mounting sealing pieces 231 a to 231 d of the upper case 202 are respectively connected to the fixing member 255. It fits in the positioning recess 256a. That is, the mounting sealing pieces 231a to 231d are arranged to face the positioning recesses 256a.

In this state, the above-described special screws 280a to 280d are screwed into the corresponding screw holes 256 from above any of the mounting sealing pieces 231a to 231d, thereby fixing the mounting sealing pieces 231a to 231d and the fixing member. 255 is fixed (caulked).

  As described above, in the substrate case 200, when the lower case 201 and the upper case 202 are sealed, the tips of the locking pieces 232 and 232 for locking the upper case 202 are connected to the lower case 201. The mounting base 250 is formed on the mounting base 250 using the locking pieces 232, 232 protruding from the locking holes 211, 211 while being inserted and locked into the locking holes 211, 211 as assembly locking notches. The board case 200 in a sealed state is locked to the mounting base 250 by inserting and locking into the locking holes 266 and 266 as the mounting locking notches and making this insertion locking state unreleasable. Can be attached. Therefore, it is not necessary to provide the locking pieces for locking and mounting on the mounting base 250 separately from the locking pieces 232 and 232 for sealing the upper case 202 and the lower case 201. Since the locking piece for sealing and attachment can be used together, the structure is simplified and the manufacturing cost is not increased.

  Here, a specific fixing method using the special screws 280a to 280e will be described. As shown in FIG. 13, by rotating the upper member 284 with a tool such as a screw driver, the screw portion 283 is inserted into the screw hole 256, and the tool such as a screw driver is further rotated to apply a torsional load exceeding a predetermined value to the upper portion. In addition to the member 284, the connecting portion 287 between the head 285 and the upper member 284 is cut. Therefore, when the fixing with the special screw 280d is executed, the upper member 284 is confined in the internal space of the mounting sealing piece 231d, so even if any tool is inserted from the opening 291 provided in the cap 290d, The tool cannot reach the special screw 280d. That is, it is difficult to release the sticking even if the sticking by the special screw 280d is illegally released. The same applies to the special screws 280a to 280c and 280e.

  Further, a metal plate 255 a having a hole portion 255 b provided at a position corresponding to the screw hole 256 is embedded inside the fixing member 255. The diameter of the hole portion 255b is slightly smaller than the diameter of the screw portion 283 (specifically, the diameter immediately above and below the constricted portion 286) of the special screws 280a to 280d, and is slightly smaller than the lower end portion of the constricted portion 286. The diameter of the constricted portion 286 formed in the middle of H.283 is almost the same.

  For example, when the special screw 280d is screwed, the tip of the special screw 280d passes through the hole 255b in the plate 255a, and the screw portion 283 in the special screw 280d pushes the outer peripheral portion of the hole 255b downward. While passing through the hole 255b.

  Inside the fixing member 255, the plate 255a is installed at a position where the hole 255b in the plate 255a fits into the constricted portion 286 when the tip of the special screw 280d reaches the bottom of the screw hole 256. At this time, the lower surface of the head 285 is in contact with the bottom surface of the mounting sealing piece 231d. Accordingly, when the special screw 280d is screwed, the constricted portion 286 is fitted into the hole portion 255b. Then, it becomes more difficult to remove the special screw 280d illegally by some means.

  That is, even if the special screw 280d (specifically, the screw portion 283) is rotated in the direction opposite to the direction in which the special screw 280d is rotated (in this example, counterclockwise), the constricted portion 286 remains in the plate 255a. Therefore, the screw portion 283 cannot move upward. That is, the plate 255a restricts the movement of the special screw 280d in such a direction that the special screw 280d enters the screw hole 256 and then leaves the screw hole 256.

  Although the case where the special screw 280d is screwed has been described here, the special screws 280a to 280c and 280e are also screwed in the same manner as when the special screw 280d is screwed. Therefore, it becomes more difficult to illegally remove the special screws 280a to 280c and 280e by some means. In addition, although the whole fixing | fixed part (special screw 280a-280c, 280e) which is not yet used for fixation is accommodated in the accommodating means (attachment sealing piece 231a-231c, 231e and cap 290a-290c, 290e). A part of the front end side of the attachment fixing means (in this example, the front end side of the screw portion 283) may protrude from the storage means as long as positioning is not hindered.

  Further, inside the fixing member 255, a metal plate 255a provided with a hole 255b at a position corresponding to the screw hole 256 is embedded (see FIGS. 12 and 13).

When the upper case 202 is removed from the attachment base 250 after the attachment state with the special screw 280 as the attachment fixing means is released, the special screw 280 cannot be removed by turning counterclockwise, so the lower case 201 or the upper case 202 is removed. Or the connecting portion 270 is cut with a tool such as a nipper, and the mounting sealing pieces 231a to 231d fixed to the fixing pieces (cylindrical portions) via special screws 280 are used as the upper case. There is no choice but to disconnect from 202.

No matter which one of the methods of destroying or cut, when to release the attached state detaching the upper case 202 from the mounting base 2 50, leaving traces of breaking or cutting. FIG. 13 shows a state in which a cut mark of the connecting portion 270 remains when the attachment sealing piece 231d is cut off from the upper case 202 by cutting the connecting portion 270.

  For example, even when the upper case 202 is removed due to a fraudulent act, it is possible to find out that the fraudulent act has been performed at an early stage by cutting marks or the like. Therefore, even if the game control board 40 having the ROM storing the illegal game control program is replaced, it can be discovered and dealt with early. Therefore, it can be avoided that the game is played in that state and the game store suffers a disadvantage.

  In addition, after the first fixing by the special screw 280d, after the connecting portion 270 for the mounting sealing piece 231d is cut for some reason (for example, for the purpose of inspecting the board), the mounting state is realized again. Is a state in which the special screw 280d is screwed.

  In addition, when the connecting portion 270 of the mounting sealing piece 231d is cut for a proper reason and then fixed by the third special screw 280c, the upper member 284 is confined in the internal space of the mounting sealing piece 231c. Therefore, even if a tool is inserted through the opening 291 provided in the cap 290c, the tool cannot reach the special screw 280c. That is, it is difficult to release the fixation even if the fixation by the special screw 280c is illegally released. The same applies to the special screws 280a and 280b.

  Then, any one of the plurality of mounting sealing pieces 231a to 231d and the fixing member 255 are fixed by special screws 280a to 280e, so that the mounting base at the end of the board case 200 on the mounting sealing pieces 231a to 231d side is provided. The movement (rotation) in the removal direction from 250 is restricted, and the sliding movement of the substrate case 200 toward the attachment sealing pieces 231a to 231d is also restricted. The stop pieces 232 and 232 are removed from the locking holes 266 and 266 of the mounting base 250, that is, the mounting state is such that the one-side locking cannot be released. Further, in this mounted state, all the screw holes 252 of the bottom plate 250a of the mounting base 250 are covered with the substrate case 200, making it impossible to access the mounting screws 259, and it is impossible to remove the mounting base 250 from the housing. It becomes.

In this way, the substrate case 200 to which the attachment side member 510 is attached is fixed to the housing via the attachment base 250, and the substrate case 200 is not broken unless the attachment sealing pieces 231a to 231d or the fixing member 255 are broken. the the mounting state can not be removed from the mounting base 2 50 is a mounting portion of the housing. At this time, since the substrate case 200 is fixed to the mounting base 250 in a state where the lower case 201 constituting the substrate case 200 is sandwiched between the upper case 202 and the mounting base 250, the mounting sealing piece 231a. Unless the .about.231d or the fixing member 255 is broken, the upper case 202 is opened with respect to the lower case 201, and the game control board 40 can be taken out of the sealed state. That is, the fixing of the mounting sealing pieces 231a to 231d and the fixing member 255 includes an attachment state in which the substrate case 200 is attached to the attachment base 250, a sealing state in which the lower case 201 and the upper case 202 are sealed, Form both.

  Further, the fixing with the special screw 280 as described above is not only the fixing of the mounting sealing pieces 231a to 231d and the fixing member 255, but also the upper sealing piece 230 and the lower sealing piece 231 are fixed and sealed. It is also used when forming.

When assembling the upper Futomehen 230 and lower Futomehen 215 and the sealing state and the lower case 201 and upper case 202 and fixed by special screws 280e, although not particularly shown, a tool such as a screwdriver, upper portion By rotating the member 284, the screw portion 283 is inserted into the screw hole 256, and further a torsional load exceeding a predetermined value is applied to the upper member 284 by rotating a tool such as a screw driver, and the head 285 and the upper member 284 are connected. The connecting portion 287 is cut. Therefore, when the fixing with the special screw 280e is executed, the upper member 284 is confined in the internal space of the upper sealing piece 230, so even if any tool is inserted from the opening 291 provided in the cap 290e, The tool cannot reach the special screw 280e. That is, even if the special screw 280e is illegally released, it is difficult to release the fixation, and the sealed state cannot be released unless the lower case 201 or the upper case 202 is destroyed.

  Further, inside the lower sealing piece 215, the plate 255c is installed at a position where the hole 255b in the plate 255c fits into the constricted portion 286 when the tip of the special screw 280e reaches the bottom of the screw hole 256. Has been. At this time, the lower surface of the head 285 is in contact with the bottom surface of the upper sealing piece 230. Therefore, when the special screw 280e is screwed, the constricted portion 286 is fitted into the hole portion 255b. Then, it becomes more difficult to remove the special screw 280e illegally by some means.

  That is, even if the special screw 280e (specifically, the screw portion 283) is rotated in the direction opposite to the direction in which the special screw 280e is rotated (in this example, counterclockwise), the constricted portion 286 is not removed from the plate 255c. Therefore, the screw portion 283 cannot move upward. That is, the plate 255c restricts the special screw 280e from moving in a direction so as to be detached from the screw hole 256 after entering the screw hole 256.

  Thus, the upper sealing piece 230, the lower sealing piece 215, and the special screw 280e constitute a second assembly fixing means for assembling the upper case 202 and the lower case 201 in a sealed state that cannot be opened. Thus, after the special sealing state by the lower fixing piece 213 and the upper fixing piece 205 is released, the upper case 202 and the lower case 201 can be assembled again in a sealed state.

  When the board case 200 to which the attachment side member 510 is attached is fixed to the attachment base 250 (housing) so as not to be removed, as shown in FIG. 18A, the side piece 510d of the attachment side member 510 is provided. , 510d abuts against the inner surface of the bulging portion 261 of the side wall 250b, 250b of the mounting base 250, and is sandwiched so as to restrict the outward deformation of both side pieces 510d, 510d of the mounting side member 510. It becomes impossible to remove 510 from the substrate case 200.

  Next, the cable-side connector of the cable 600a with respect to the board-side connectors 620a and 620b of the game control board 40 exposed through the insertion holes 234a and 234b of the board case 200 and the notch 512 of the base piece 510a in the attachment-side member 510. After connecting the cable side connector 610d of the cable 610a and the cable 600d, the connector cover 610a and the cable side connector 610a, and the board side connector 620d and the cable side connector 610d are connected as shown in FIG. The upper portion of the cable side connector 610 a is covered with the covering portion 521 of 520, and the locking cylinder 522 of the connector cover 520 is fitted into the locking hole 513 a of the locking hole portion 513 in the attachment side member 510. As a result, the engaging portions 523 and 523 of the locking cylinder 522 abut against the inner periphery of the locking hole 513a and elastically deform inward.

  At this time, when the engaging portions 523 and 523 are positioned so as to cover the cable-side connector 610a with the covering portion 521, the shallow grooves 514a and 514a of the engaging grooves 514 and 514 formed on the inner surface of the engaging hole 513a are naturally formed. The locking cylinder 522 is further inserted, and the locking claws 523a and 523a at the tips of the engaging portions 523 and 523 reach the shallow groove portions 514a and 514a of the locking grooves 514 and 514, As shown in FIG. 16A, the inward elastic deformation of the engaging portions 523 and 523 is released, and the locking claws 523a and 523a engage with the shallow groove portions 514a and 514a, respectively. The upward movement is restricted, and the side surface 521a of the covering portion 521 is brought into contact with the side surfaces of the board-side connector 620a and the cable-side connector 610a, so that the locking cylinder 522 is locked. By rotating against the part 513 is restricted, and ligated with the mounting member 510 and the connector cover 520, a state of integrated connector regulating member 500 is formed. In this state, since the engaging portions 523 and 523 are covered with the locking hole portion 513, it is impossible to elastically deform the engaging portions 523 and 523 inward from the outside, and the connector cover 520 or the attachment side member Unless 510 is broken, the connector cover 520 cannot be removed from the attachment side member 510.

  When the connector cover 520 is attached to the attachment-side member 510 so as not to be detached, a part of the upper surface of the cable-side connector 610a is covered by the covering portion 521 as shown in FIGS. The movement of the side connector 610a from the board-side connector 620a is restricted, and the removal of the cable-side connector 610a from the board-side connector 620a is restricted.

  As described above, with the mounting side member 510 attached to the board case 200, the board case 200 is fixed to the housing, and then the cable side connector 610a is connected to the board side connector 620a. By attaching a part of 620a to the attachment side member 510 so as to cover from above, the cable side connector 610a cannot be removed from the board side connector 620a.

  Next, a situation when the connection between the cable side connector 610a and the board side connector 620a is released will be described.

  To release the connection between the cable-side connector 610a and the board-side connector 620a, the attachment-side member 510 or the connector cover 520 is broken and the connector cover 520 is detached from the attachment-side member 510, or the attachment sealing piece of the board case 200 It is necessary to break the 231a to 231d or the fixing member 255, remove the board case 200 from the attachment base 250, and remove the attachment side member 510 with the connector cover 520 attached thereto from the board case 200.

  For example, when it is necessary to remove the cable-side connector 610a from the board-side connector 620a due to a failure of the cable 600a or the like, the latter method is used when the board case 200 is to be removed and replaced by the former method. Just remove it.

  First, when replacing the cable 600a, when it is necessary to remove the cable-side connector 610a from the board-side connector 620a, a method for removing the connector cover 520 constituting the connector regulating member 500 from the attachment-side member 510 will be described first. The connection piece 522a that connects the cover portion 521 of the connector cover 520 and the locking cylinder 522 is broken with a tool such as a nipper. As a result, the covering portion 521 is separated and the locking cylinder 522 can be rotated with respect to the locking hole portion 513. In this state, by rotating the locking cylinder 522 counterclockwise when viewed from above, the engaging portions 523 and 523 move from the shallow groove portions 514a and 514a of the locking grooves 514 and 514 to the positions of the deep groove portions 514b and 514b. Then, as shown in FIG. 16A, from the state where the locking claws 523a and 523a are engaged with the shallow groove portions 514a and 514a, as shown in FIG. 16B, the locking claws 523a and 523a The shallow groove portions 514a and 514a are disengaged. Accordingly, the locking cylinder 522 can be moved upward. As shown in FIG. 16C, when the locking cylinder 522 is pulled upward, the locking claws 523a and 523a are engaged with the deep grooves 514b and 514b. However, in this state, since the engaging portions 523 and 523 are exposed, the engaging portions 523 and 523 can be elastically deformed inward, and the engaging claws 523a can be elastically deformed inwardly. 523a and the deep groove portions 514b and 514b are disengaged, and the locking cylinder 522 can be detached from the attachment side member 510, whereby the connector cover 520 is completely separated from the attachment side member 510, and the connector cover 520 Since the restriction of the movement in the pulling direction of the cable side connector 610a due to is also released, the connection between the cable side connector 610a and the board side connector 620a is released. Door will be able to.

  When the connector cover 520 is removed from the attachment side member 510, the covering portion 521 and the locking cylinder 522 are broken, and once broken, the original state is not restored. Therefore, the connection between the cable side connector 610a and the board side connector 620a is not possible. There will be traces of unlocking.

  Next, when it is necessary to remove the cable side connector 610a from the board side connector 620a when replacing the whole board case 200, a method of removing the attachment side member 510 from the board case 200 together with the connector cover 520 will be described. The attachment sealing pieces 231a to 231d of the substrate case 200 fixed to the fixing member 255 with a tool such as a nipper are broken. As a result, the end of the substrate case 200 on the side of the mounting sealing pieces 231a to 231d can be moved away from the mounting base 250, so that the locking pieces 232 and 232 are engaged with the locking holes 266. Is released. Thereby, the board case 200 is detached from the attachment base 250, and the side pieces 510d and 510d of the attachment side member 510 can be deformed outwardly, without removing the connector cover 520 from the attachment side member 510. The attachment-side member 510 can be removed from the board case 200. With this, the attachment-side member 510 is removed from the board case 200 in a state of being integrated with the connector cover 520, whereby the cable-side connector 610a is removed by the connector cover 520. Since the restriction on the movement in the direction is also released, the connection between the cable side connector 610a and the board side connector 620a can be released.

  In order to remove the attachment side member 510 from the substrate case 200 also by this method, it is necessary to break the attachment sealing pieces 231a to 231d of the substrate case 200 fixed to the fixing member 255. Therefore, the trace that the connection between the cable side connector 610a and the board side connector 620a is released remains.

  Further, according to this method, the attachment sealing pieces 231a to 231d of the substrate case 200 are broken and remain on the fixing member 255, but the attachment side member 510 is attached to the substrate case without removing the connector cover 520 from the attachment side member 510. Since the attachment side member 510 in which the connector cover 520 is assembled is attached to a new board case 200 in which the game control board 40 is accommodated for replacement, the cable side connector 610a in the new board case 200 can be removed. And the board-side connector 620a are disabled from being released, and a new board case 200 in which a new fixing member 255 is mounted on the mounting base 250 and the mounting-side member 510 with the connector cover 520 assembled thereto is mounted. Is attached to the attachment base 250 and attached to the fixing member 255. By fixing the stop pieces 231a to 231d, it becomes impossible to remove the attachment-side member 510 again, and when the connection between the cable-side connector 610a and the board-side connector 620a is released, the state in which the trace can be left. It becomes. That is, in such a case, the attachment side member 510 and the connector cover 520 can be reused.

  In this embodiment, the engaging pieces 511 and 511 of the attachment side member 510 are elastically deformed outward and engaged with the engaging grooves 514 and 514 formed on the back surface of the substrate case 200. When the attachment side member 510 is attached to the substrate case 200 and the substrate case 200 to which the attachment side member 510 is attached is fixed to the attachment base 250 (housing) so as not to be detached, the attachment side member 510 side Since the pieces 510d and 510d abut against the inner surfaces of the side walls 250b and 250c of the mounting base 250 and are held between the pieces, the deformation of the both side pieces 510d and 510d of the mounting side member 510 is restricted outward. For example, a part of the attachment side member is screwed on the back surface of the substrate case 200 or a removable locking pin. And fixing the board case 200 to the housing (mounting base) in a non-removable manner, the screws and locking pins are concealed, and the board case 200 is attached to the housing, The attachment side member may be controlled to be removed from the substrate case 200. After the attachment case is fixed to the housing with the attachment member attached to the substrate case 200, the attachment member is the substrate. Any configuration may be adopted as long as it cannot be removed from the case 200.

  Next, the mounting state of the mounting table 660 and the cover member 680 will be described. First, as shown in FIG. 19, the operation unit relay board 110 is mounted on the mounting table 660, and the board-side connectors 621a, 622a to 622c, 622d. Cable-side connectors 611a, 612a to 612c, 612d to 612f, 612g, and 612q respectively corresponding to ˜622f, 622g, and 622q are connected. After connecting these cable side connectors to the board side connector, the cover member 680 is attached to the mounting table 660.

Specifically, the locking cylinder 634 of the cover member 680 is fitted into the locking hole 661 b of the corresponding locking hole 661 of the mounting table 660. Then by pushing the locking sleeve 634 in the retaining hole 661b, the locking claws 661c of the engaging hole 661b is engaged with the locking hole 684 b of the locking cylinder 684. Thus, it is the impossible state to disengage from the outer locking claws 661c and the retaining hole 684 b, as shown in FIG. 20, the mounting table 660 and the cover member 680 is engaging If the hole 661 or the locking cylinder 634 is not broken, it is assembled so as not to be removable.

  When the mounting table 660 and the cover member 680 are assembled, as shown in FIG. 21A, the upper surfaces of both ends of the cable-side connector 611a connected to the board-side connector 621a of the operation unit relay board 110 are the cover members. The covering surfaces 681c and 681c of 680 are covered, the movement of the cable-side connector 611a in the pulling direction from the board-side connector 621a is restricted, and the removal of the cable-side connector 611a from the board-side connector 621a is restricted. ing.

  When the mounting table 660 and the cover member 680 are assembled, as shown in FIG. 21B, upper surfaces of both ends of the cable side connector 612g connected to the board side connector 622g of the operation unit relay board 110, and the operation unit relay. The upper surfaces of both ends of the cable-side connector 612q connected to the board-side connector 622q of the board 110 are covered with the covering pieces 683, 683, 683 of the cover member 680, and the cable-side connector 612g is removed from the board-side connector 622g. The movement and the movement of the cable side connector 612q in the direction from the board side connector 622q are restricted, and the removal of the cable side connector 612g from the board side connector 622g and the removal of the cable side connector 612q from the board side connector 622q are restricted. It has come to be.

  Next, the connection between the cable side connector 611a and the board side connector 621a, the connection between the cable side connector 612g and the board side connector 622g, and the situation when releasing the connection between the cable side connector 612q and the board side connector 622q will be described. .

  To release the connection between the cable side connector 611a and the board side connector 621a, the connection between the cable side connector 612g and the board side connector 622g, and the connection between the cable side connector 612q and the board side connector 622q, cover with a tool such as a nipper. The connecting piece 684a connecting the locking cylinder 684 of the member 680 is broken. As a result, the main body of the cover member 680 and the locking cylinder 684 are separated, and the cover member 680 can be removed from the mounting table 660. By removing the cover member 680 from the mounting table 660, the covering surfaces 681c, 681c The restriction on the movement of the cable side connector 611a in the unplugging direction is released, and the restriction on the movement of the cable side connector 612g in the unplugging direction and the movement of the cable side connector 612q in the unplugging direction by the covering pieces 683, 683, 683 is also released. Therefore, the connection between the cable side connector 611a and the board side connector 621a, the connection between the cable side connector 612g and the board side connector 622g, and the connection between the cable side connector 612q and the board side connector 622q can be released. .

  When the cover member 680 is removed from the mounting table 660, the main body of the cover member 680 and the locking cylinder 684 are broken. Once the cover member 680 is broken, the original state is not obtained, and the separated locking cylinder 684 is removed from the mounting table 660. Therefore, the cable side connector 611a and the board side connector 621a are connected, the cable side connector 612g and the board side connector 622g are connected, and the cable side connector 612q and the board side connector are connected. The trace which canceled the connection with 622q will remain.

  Next, a substrate case 200 ′ as a modified example of the present invention will be described based on FIGS. 22 and 23. FIG. 22 is a perspective view showing a substrate case as a modification of the present invention. FIG. 23A is an enlarged perspective view of a main part showing a situation where the upper case is slid with respect to the lower case, and FIG. 23B is a main part showing a state where the upper case is locked with respect to the lower case. It is an expansion perspective view.

  In the substrate case 200 of the embodiment, the upper case 202 is slid with respect to the lower case 201, so that the locking pieces 232 and 232 formed on one side wall 202 d of the upper case 202 are moved to the side wall of the lower case 201. The lower fixing pieces 213 and 213 are arranged to face each other on the upper surface side of the upper fixing pieces 205 and 205 constituting the special fixing portion by being inserted into the locking holes 211 and 211 formed in the 201c. The upper case 202 is locked, but in the board case 200 ′ of this modification, the upper case 202 is slid with respect to the lower case 201, whereby the side walls 202 b and 202 b of the upper case 202 are moved. Engagement pieces 710 (inner surfaces of the side walls 202b and 202b) formed at both ends in the longitudinal direction of the inner surfaces. In FIG. 23 (a), only the engaging piece 710 formed at one end in the longitudinal direction is shown in FIG. 23 (a), and the engaging grooves 711 formed on the side walls 201b and 201b of the lower case 201 (side walls 201b and 201b, respectively). In FIG. 23 (a), only the engaging groove 711 formed at one end in the longitudinal direction is engaged), and the upper fixing pieces 205, 205 are formed on the upper surfaces of the lower fixing pieces 213, 213. The upper surfaces of the lower fixing pieces 213 and 213 are opposed to each other and are locked by a pair of locking claws 712 and 712 provided on the lower case 201 side.

  As described above, the upper fixing pieces 205 and 205 and the lower fixing pieces 213 and 213 constituting the special fixing portion have the vertical positional relationship when the upper case 202 is aligned with the lower case 201 in the above-described embodiment. It may be the opposite of the substrate case 200, and the same operation and effect as in the above embodiment can be obtained.

  Further, the annular concave groove 214 only needs to be formed on at least one of the opposing surfaces of the upper fixing pieces 205 and 205 and the lower fixing pieces 213 and 213. In this modification, the upper fixing pieces 205 and 205 are formed. It is formed on the lower surface.

  Further, in the substrate case 200 of the above embodiment, the caps 290a to 290e that close the upper surface openings of the upper sealing piece 230 and the mounting sealing pieces 231a to 231d are provided separately from the substrate case 200. In the present modification, the lower case 201 is integrally formed with a closing portion 700 that closes the upper surface openings of the mounting sealing pieces 231a to 231d in the closed state. The closing portion 700 includes a closing plate 700a disposed at a closing position that closes the top opening of each mounting sealing piece 231a to 231d in the closed state, and the top surface of each mounting sealing piece 231a to 231d in the closing plate 700a. An opening (operation hole) 701 is formed at a position facing the opening.

  Moreover, since the closure part 700 is formed in the box shape which one side opens so that side surfaces other than the connection part 270 side of each attachment sealing piece 231a-231d may be covered, attachment sealing piece 231a-231d. On the other hand, since the mounting sealing pieces 231a to 231d are formed of a transparent resin material so that the mounting sealing pieces 231a to 231d can be seen through, an illegal act on the mounting sealing pieces 231a to 231d is performed. It is possible to visually confirm that there is a possibility that

  Further, in the substrate case 200 ′, the upper sealing piece 230 is arranged below the lower sealing piece 215 in the closed state. Further, a screw storage portion 703 for storing a conventionally known one-way screw 704 is provided on the base side of the upper sealing piece 230 instead of the special screw 280. When the one-way screw 704 is not used, the upper seal It can be stored in a screw storage portion 703 provided separately from the stop piece 230. Note that the one-way screw 704 stored in the screw storage portion 703 is restricted from coming off from the screw storage portion 703 by the lower sealing piece 215 in the closed state.

  The thus configured substrate case 200 'of the present modification has the same operations and effects as the substrate case 200 of the above-described embodiment.

  As described above, in the slot machine 1 of the embodiment, various boards such as the game control board 40 provided with the main control unit 41 for controlling the game are mounted. Electronic components such as switches or the like that can be operated by the game are connected via a cable.

  The cables connecting these electronic components and the board are generally separable by releasing the connection at the connector in order to facilitate the assembling work and the wiring work at the time of manufacturing the gaming machine. In addition, since the electronic parts are common parts that are used continuously without changing even when changing the model, etc., they are fixed to the main body of the slot machine. For example, the game control board 40 is replaced when a failure or model change occurs. Therefore, for example, by removing the cable side connector from the board side connector provided on the game control board 40 and releasing the connection, the game control board 40 can be easily taken out from the main body and replaced. Yes.

  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 electronic component can be easily released by removing the connector, the cable from the board-side connector, for example, at the game store, is shipped. The side connector is removed, and instead, the cable side connector connected to an unauthorized instrument such as a so-called driving instrument can be easily connected to the board side connector.

  The driving tool is, for example, a signal obtained by simulating a signal input / output to / from the game control board 40 from the above-mentioned various electronic components to / from the game control board 40, thereby enabling various switches provided in the slot machine. 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, in the case where illegal sales such as providing a slot machine set in a state where a special role is won using such an illegal driving tool to a player at the start of business at a game shop, There was a risk that the fairness of this would be impaired.

  On the other hand, in the present embodiment, the connector connection between the game control board 40 and the inserted medal sensor 31, that is, the connection between the board side connector 620a of the game control board 40 and the cable side connector 610a of the cable 600a, the cable 600a Connection between the cable-side connector 611a and the board-side connector 621a of the operation unit relay board 110, and connection between the board-side connector 622g of the operation part relay board 110 and the cable-side connector 612g of the cable 601g, release the connection between these connectors. The connector restricting member 500 and the connector restricting member 650 are used for restriction. As a result, one of the connectors between the game control board 40 and the inserted medal sensor 31 is replaced with a connector such as an illegal driving tool and connected to the main control unit 41 of the game control board 40 for illegal actions relating to the progress of the game. For example, it is difficult to conduct illegal activities such as inputting / outputting various signals. For example, it is effective to conduct illegal sales such as providing a slot machine with a bonus winning condition by connecting a driving tool etc. Can be prevented.

  Further, the connector connection between the game control board 40 and the door opening detection switch 25, that is, the connection between the board side connector 620a of the game control board 40 and the cable side connector 610a of the cable 600a, and the operation with the cable side connector 611a of the cable 600a. The connection between the connector relay member 110 and the connector 621a of the operation unit relay substrate 110, and the connection of the connector 622q of the connector relay substrate 110 and the cable connector 612q of the cable 601q are canceled. It regulates by the regulating member 650. This makes it difficult to release the connection between any of the connectors between the game control board 40 and the door opening detection switch 25, so that the front door 2b is not notified that the front door 2b has been opened. It is possible to effectively prevent the door 2b from being opened.

  In order to release the connector connection between the game control board 40 and the inserted medal sensor 31 or the connector connection between the game control board 40 and the door opening detection switch 25, the mounting sealing piece 231a of the board case 200 is used. ˜231d, the connection piece 522a of the connector cover 520, and the connection piece 684a of the cover member 680 must be broken, so that the connector connection between the game control board 40 and the inserted medal sensor 31 or the game control board 40 If even one connector connection with the door opening detection switch 25 is released, the trace remains and it is extremely difficult to erase the trace, so that the illegal business or the front door 2b has been opened. Opening of the front door 2b in a state where no notification is made can be more effectively suppressed.

  Further, in this embodiment, there is only one relay board between the game control board 40 and the insertion medal sensor 31 and between the game control board 40 and the door opening detection switch 25, but it passes through a plurality of relay boards. In this case, it is preferable to restrict removal of all connector connections existing between them, and in this way, between the game control board 40 and the inserted medal sensor 31 or the game control board 40 and the door opening detection switch. Since it is difficult to release the connection of any of the connectors with the front door 25, the front door 2b can be more effectively opened in the state where the unauthorized sales or the notification that the front door 2b is opened is not issued. Can be prevented.

In the present embodiment, the first electronic components 5 , 6 , 7 , 8L , 8C, 8R , 31, 33L, 33C, 33R, which input signals to the game control board 40 according to the progress of the game, 3 4c and second electronic component 32L of the game signal from the game controller board 40 according to the progress of outputs, 32C, of 32R, 34 b, connector connection between the medal sensor 31 and the gaming control board 40 Only the connector restricting member is provided to restrict the connection between the connectors. That is, the inserted medal sensor 31 which cannot advance the game without the signal (the bet number cannot be set and the game cannot be started unless the signal from the inserted medal sensor 31 is input) and the game control. The connector restricting member is provided only for the connector connection with the board 40 to restrict the release of the connection between the connectors, and the connection between the connectors is released between the other electronic components and the game control board 40 to drive the instrument. even when replaced on the connector, it becomes impossible to proceed automatically substantially player, it is possible to prevent fraud with minimal regulation part for releasing the connection of connectors The score can be reduced.

  In this embodiment, only the connector connection between the inserted medal sensor 31 and the game control board 40 is provided with a connector restricting member to restrict the connection between the connectors, but the start switch 7 and the game control board 40 are not connected. The same effect can be obtained even if a connector restricting member is provided only for connector connection between the connector and the release of the connection between the connectors is restricted. 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 the present embodiment, a plurality of signal lines for connecting the main control unit 41 and a plurality of electronic components for inputting / outputting signals necessary for the progress of the game and the door opening detection switch 25 are connected to the game control board 40. Since it is connected to the operation unit relay board 110 with 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, the connection of only one connector is released. By restricting, it becomes possible to restrict the release of the connection between the plurality of signal lines, and it is not necessary to prepare a plurality of parts for restricting the release of the connector connection, and the number of these parts can be reduced.

  When a plurality of signal lines for connecting the main control unit 41 and a plurality of electronic 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.

  Further, in this embodiment, the connection between the cable side connector 611a of the cable 600a connecting the game control board 40 and the operation unit relay board 110 and the board side connector 621a of the operation part relay board 110 is released, and the operation unit relay board 110 is connected. The cable side connector 612g of the cable 601g that connects the inserted medal sensor 31 and the board side connector 622g of the operation unit relay board 110, and the cable 601q that connects the operation unit relay board 110 and the door opening detection switch 25. Since the release of the connection between the cable-side connector 612q and the board-side connector 622q of the operation unit relay board 110 is simultaneously restricted by one connector restricting member 650, a component for restricting the release of the plurality of connector connections This eliminates the need to prepare multiple parts and reduces the number of these parts

  Further, in this embodiment, the board side connector 620a and the cable side of the game control board accommodated in the board case 200 are attached by attaching the connector regulating member 500 including the attachment side member 510 and the connector cover 520 to the board case 200. The connector 610a is prevented from being removed and attached, and in this state, the board case 200 is attached to the mounting base 250, and the fixing member 255 and the mounting sealing pieces 231a to 231d are fixed to each other. 500 is restricted, the attachment sealing pieces 231a to 231d of the substrate case 200 are broken to release the fixation between the substrate case 200 and the housing (attachment base 250), or the attachment side member 510 or If the attached state of the connector cover 520 is not released, the board-side connector 620 A state that can not be pulled out of the cable-side connector 610a from. That is, the cable-side connector 610a cannot be removed without leaving a trace that the mounting sealing pieces 231a to 231d are broken or the connection piece 522a is broken, and an unauthorized instrument such as a driving instrument is connected without leaving any trace. Or the connection of the connector cannot be released, so that it is possible to reliably detect that there is a possibility of fraud.

  In addition, when the game control board 40 is exchanged together with the board case 200 containing the game control board 40 due to a failure or the like, the attachment sealing pieces 231a to 231d are broken and the board case 200 and the housing (attachment base 250) are separated. Is released from the board case 200 and the cable-side connector 610a can be removed from the board-side connector 620a. Therefore, the connector restriction member 500 can be destroyed or the board case 200 can be removed. The cable-side connector 610a can be separated from the board-side connector 620a without breaking and opening.

  Further, the connector restricting member 500 is composed of an attachment side member 510 and a connector cover 520. After the attachment side member 510 is attached to the board case 200, the cable side connector 610a is connected to the board side connector 620a, and the board is in that state. The cable-side connector 610a cannot be removed from the board-side connector 620a by being attached to the attachment-side member 510 so as to cover a part of the cable-side connector 620a from above. Is connected to the board-side connector 620a, and then the locking cylinder 522 of the connector cover 520 is fitted into the locking hole 513a of the locking hole 513 of the attachment-side member 510 located around the board-side connector 620a. The connector cover 520 is simply attached to the attachment side member 510. Since part of the cable-side connector 610a is covered and the movement of the cable-side connector 610a in the unplugging direction is restricted, the assembly work is reduced in restricting the removal of the cable-side connector 610a from the board-side connector 620a. it can.

  Further, even when the game control board 40 is housed in the board case 200, it is only necessary to connect the cable side connector 610a to the board side connector 620a as it is, and then attach the connector cover 520. In this case, the assembly work can be more effectively reduced when the removal of the cable-side connector 610a from the board-side connector 620a is restricted.

  Further, the connector cover 520 does not cover the entire connection portion between the cable-side connector 610a and the board-side connector 620a, but covers only a part of the cable-side connector 610a in the pulling direction side. Not only can the removal of the connector 610a with respect to the board-side connector 620a be surely restricted, but the amount of material required for manufacturing the connector cover 520 can be reduced.

  Further, since the connector cover 520 is attached to the attachment side member 510 with only one locking cylinder 522, the structure of the connector cover 520 and the attachment side member 510 can be simplified. A plurality of stop cylinders 522 may be provided, and a locking hole 513a may be provided at a corresponding location on the attachment side member 510, and the connector cover 520 may be attached to the attachment side member 510 at a plurality of locations. By doing so, the removal of the cable-side connector 610a from the board-side connector 620a can be more firmly regulated. Furthermore, in this case, it is preferable that the connector cover 520 is attached to the attachment side member 510 at a plurality of locations across the connection portion between the cable side connector 610a and the board side connector 620a.

Removal from the machine is disabled.

  Therefore, for example, only the mounting sealing pieces 231a to 231d are provided, and by fixing the mounting sealing pieces 231a to 231d and the fixing member 255, the opening of the upper case 202 and the lower case 201 is disabled, and the substrate The case 200 may be configured such that it cannot be removed from the slot machine body.

  In the above embodiment, the lower fixing piece 213 of the lower case 201 and the upper fixing piece 205 of the upper case are formed in a plate shape, but when the lower case 201 and the upper case 202 are aligned in the closed position, If it has the opposing surface which mutually opposes, the shape is not limited to a plate-shaped thing.

  Moreover, although the lower fixing piece 213 of the lower case 201 and the upper fixing piece 205 of the upper case are made of thermoplastic resin, the material is not limited to thermoplastic resin as long as it can be welded.

  In the above-described embodiment, the lower fixing piece 213 of the lower case 201 and the upper fixing piece 205 of the upper case are fixed (caulked) by welding as the fixing portions for sealing the lower case 201 and the upper case 202. However, when the sealed state is released, if the traces of destruction are left in both the lower case 201 and the upper case 202, a special screw 280a, a one-way screw, a locking pin, etc. It may be fixed via a fixing member or a fixing member such as an adhesive.

  Further, as mounting fixing means for fixing the substrate case 200 to the mounting base 250, the mounting sealing pieces 231a to 231d and the fixing member 255 are fixed screws 280a to 280a which are fixing members provided separately from these portions. Although fixed and attached via 280e, the facing surfaces of the attachment sealing pieces 231a to 231d and the fixing member 255 may be fixed by welding, an adhesive, or the like.
