Accordingly, even when the engagement obstructing portion 212e is removed from the left and right engaging members 212 in the figure, the same shape as that of the right engaging member in the figure is obtained. By removing the engagement obstructing portion 212d in this way, the opening portion 212c becomes substantially T-shaped, and the two step portions on the side edges come into contact with a part of the engaged member 214 described later to release the engagement. The contact surface 212g is made impossible (details will be described later).

  6C to 6E are views showing the structure of the engaged member 214. 6C is a view in the direction of the arrow B in FIG. 4A, FIG. 6D is a cross-sectional view taken along the line DD in FIG. 5B, and FIG. It is a perspective view of 6 (d). The engaged member 214 includes two leg portions 214a provided on the upper portion of the upper lid 204, an outer wall portion 214b provided above the leg portion 214a, and a tongue piece 214c provided inside the outer wall portion 214b. Has been. The leg portion 214a is a short bar-like member that is integrally connected to the upper lid 204, and is a portion that can be easily cut by a nipper or the like when releasing the seal. The outer wall portion 214b is a box-like member having an opening on the lower lid 202 side, and this opening portion serves as an insertion hole 214d into which the engaging member 212 is inserted. The tongue piece 214c is a plate-like member protruding from the inner surface of the outer wall 214a opposite to the insertion hole 214d. A protruding portion 214e having a saw-tooth cross section protruding upward is formed at the distal end portion of the tongue piece 214c, and the vertical surface of the protruding portion 214e on the base end side of the tongue piece 214c is abutted against the engaging member 212. The contact surface 214f is in contact with the contact surface 212d. Further, a molding hole 214g necessary for molding the protrusion 214e is formed in the outer wall 214b above the base end of the tongue piece 214c.

  7A is a cross-sectional view taken along line EE in FIG. 5B, and FIGS. 7B and 7C are cross-sectional views taken along line FF in FIG. 5B. FIG. 7A shows a case where the engaging member 212 from which the engagement blocking portion 212e has been removed in advance and the engaged member 214 are in the engaged position. In this case, the insertion portion 212b of the engaging member 212 is accommodated in the outer wall portion 214b of the engaged member 214, and the distal end portion 212d of the insertion portion 212b is accommodated in the molding hole 214g of the engaged member 214. It has become a state. The protruding portion 214e at the tip of the tongue piece 214c of the engaged member 214 is in a state of being fitted and engaged in the opening 212c formed in the insertion portion 212b of the engaging member 212. In this state, the contact surface 212g of the engagement member 212 and the contact surface 214f of the engagement member 214 can be moved in a direction (upward in the drawing) to move the engagement member 214 away from the engagement position. , The engaged member 214 cannot be moved. That is, the engagement between the engaging member 212 and the engaged member 214 cannot be released unless at least one of the engaging member 212 and the engaged member 214 is destroyed, and the substrate case 200 has a sealing structure. Sealed by 210.

  When the engaging member 212 and the engaged member 214 are in the engaged positions, the insertion portion 212b of the engaging member 212 and the tongue piece 214c of the engaged member 214 are the outer walls of the engaged member 214. The periphery is covered by the portion 214 b and the base end portion 212 a of the engaging member 212. Further, the molding hole 214g of the engaged member 214 is blocked by the tip end portion 212d of the engaging member 212. For this reason, it is impossible to release the engagement between the engaging member 212 and the engaged member 214 by inserting a thin rod or the like from the outside.

  On the other hand, FIG. 7B shows a case where the engaging member 212 including the engaging blocking portion 212e and the engaged member 214 are in the engaged positions. Also in this case, the insertion portion 212b of the engaging member 212 is accommodated inside the outer wall portion 214b of the engaged member 214, and the distal end portion 212d at the distal end of the insertion portion 212b is within the molding hole 214g of the engaged member 214. It is in a state of being accommodated in. And the protrusion part 214e of the tongue piece 214c front-end | tip of the to-be-engaged member 214 is in the state which contact | abutted to the engagement obstruction part 212e, and was extruded from the opening part 212a. In other words, the engagement obstructing portion 212e presses the protruding portion 214e to elastically deform the tongue piece 214c, thereby arranging the contacted surface 214f at a position where it cannot contact the contact surface 212g. . Therefore, in this case, the engaging member 212 and the engaged member 214 are not engaged, and as shown in FIG. 7C, the engaged member 214 is moved away from the engaging position. be able to. Since the opening 212c formed on the distal end side of the insertion portion 212b is set to be narrower than the width of the tongue piece 214c (see FIG. 6A), the protruding portion 214e does not enter the opening 212c. There is no such thing. Thus, in this embodiment, when the engagement member 212 includes the engagement obstructing portion 212e, the engagement member 212 and the engaged member 214 can be separated from the engagement position. The sealing by the sealing structure 210 is not performed.

  In this embodiment, the substrate case 200 is provided with three sealing structures 210, and the engagement member 212 of the two sealing structures 210 among them is provided with the engagement disturbing portion 212e, so that re-sealing is performed twice. It is possible. FIGS. 8A to 8D are diagrams showing a procedure for resealing. In these drawings, the sealing structure 210 on the right side of the figure has the engagement blocking portion 212e removed in advance, and the sealing structure 210 on the left and center sides of the drawing includes the engagement blocking portion 212e. . Therefore, when the lower lid 202 and the upper lid 204 are first coupled, the engaging member 212 and the engaged member 214 of the sealing structure 210 on the right side of the drawing are engaged, and sealing is thereby performed. In this state, when the sealing of the substrate case 200 is released based on a valid reason, the leg 214a of the engaged member 214 on the right side of the drawing is attached to the nipper 216 or the like as shown in FIG. Disconnect with. As a result, the engaged member 214 engaged with the engaging member 212 is separated from the upper lid 204, and the upper lid 204 can be removed from the lower lid 202. In the left and center sealing structures 210, since the engaging member 212 includes the engaging blocking portion 212e, the engaged member 214 is separated from the lower lid 202 together with the upper lid 204, as shown in FIG. Is done. In the sealing structure 210 on the right side of the figure, the engaged member 214 remains on the lower lid 202 while being engaged with the engaging member 212. Thus, the engagement member 214 remains on the lower lid 202, so that it is easily identified that the seal has been released.

  When sealing for the second time, first, as shown in FIG. 3C, the engagement blocking portion 212e is removed from the engagement member 212 at the center of the drawing. The removal of the engagement obstructing portion 212e is performed by cutting the three connecting portions 212f with the nipper 216 or the like. Since the connection portion 212f is set to have a smaller cross-sectional area than the engagement blocking portion 212e, it can be easily cut. By removing the engagement obstructing portion 212e, one substantially T-shaped opening 212a is formed in the engaging member 212, and the contact surface 212g is the contacted surface 214f of the engaged member 214. It will be in the state which can contact | abut. Then, as shown in FIG. 4D, when the lower lid 202 and the upper lid 204 are coupled again, this time, the engaging member 212 and the engaged member 214 are engaged in the sealing structure 210 in the center of the figure. . That is, sealing is performed by the sealing structure 210 in the center of the figure. When the third sealing is performed after the second sealing is released, the engagement obstructing portion 212e of the engaging member 212 of the sealing structure 210 on the left side of the figure may be removed.

  In the present embodiment, the cut surface after cutting the connection portion 212f is formed on a surface other than the contact surface 212g. Thereby, the contact surface 212g and the contacted surface 212f can always be properly contacted without being affected by the state of the cut surface. In addition, since the connection portion 212f is formed so that the side surface of the connection portion 212f is continuous from the contact surface 212g, the side surface of the connection portion 212f remaining on the engagement member 212 after cutting is part of the contact surface 212g. It is configured. Thereby, since the area of the contact surface 212g increases, the engagement between the engaging member 212 and the engaged member 214 can be made more reliable.

  In this embodiment, the three sealing structures 210 are provided on the substrate case 200. However, the number of the sealing structures 210 is not limited to three, and other numbers of sealing structures 210 are provided. May be. For example, four or more sealing structures 210 may be provided, or only one sealing structure 210 may be provided.

  Further, in this embodiment, one of the plurality of sealing structures 210 has the engagement blocking portion 212e removed in advance, but the present invention is not limited to this. For example, all the sealing structures 210 may be provided with the engagement blocking portions 212e, and the engagement blocking portions 212e may be removed from one sealing structure 210 immediately before sealing. By doing in this way, when it is not necessary to seal, it can prevent accidentally sealing.

  Further, the engagement member 212 from which the engagement blocking portion 212e is removed in advance may be manufactured in a shape in which the engagement blocking portion 212e is omitted from the beginning as in this embodiment, or the engagement blocking portion 212e may be manufactured. The engagement obstructing portion 212e may be removed after being manufactured with the portion 212e.

  In the present embodiment, the engagement blocking portion 212e is formed on the engagement member 212, but the present invention is not limited to this. For example, the engagement hindering part 212e may be formed on the engaged member 214, or the engagement hindering part 212e may be formed on both the engaging member 212 and the engaged member 214.

  Further, in this embodiment, the engagement obstruction part 212e is formed on the engagement member 212, and a position where the contact surface 214f cannot contact the contact surface 212g by contacting a part of the member 214 to be engaged. However, the present invention is not limited to this, and the engagement hindering portion 212e is formed on the engagement member 212 and abuts against a part of the engaged member 214. 212g may be arranged at a position where it cannot come into contact with the contacted surface 214f. Further, the engagement obstructing portion 212e is formed on the engaged member 214, and abuts on a part of the engaging member 212 and places the abutting surface 212g at a position where it cannot abut on the abutted surface 214f. Alternatively, the contact member 214 is formed on the engaged member 214 and contacts with a part of the engagement member 212 so that the contacted surface 214f cannot be contacted with the contact surface 212g. May be.

Further, the sealing structure 210 may be composed of a member having transparency so that at least the sealing (engaged) state can be discriminated, or composed of a non-permeable member. May be.
<Electronic parts sealing structure>

  Next, the electronic component sealing structure 220 that seals the removal of the electronic components disposed on the main control board 192 will be described with reference to FIG. FIG. 9 is an exploded perspective view showing the structure of the electronic component sealing structure 220. In the present embodiment, in addition to the sealing of the substrate case 200, an electronic component sealing structure 220 for sealing the removal of the ROM 306 disposed on the main control board 192 is further provided. Note that the ROM 306 is disposed on the upper surface of the main control board 192 (positioned above), and the direction will be described below.

  The ROM 306 is disposed on the main control board 192 via a socket 306 a disposed on the main control board 192. The socket 306a is fixed on the main control board 192 by soldering the foot 306b to the main control board 192, and has a plurality of insertion holes 306c on the upper surface. The ROM 306 is disposed with the lead 306d inserted into the insertion hole 306c. That is, the ROM 306 can be easily attached and detached by simply inserting and removing the lead 306d into the insertion hole 306c of the socket 306a.

  As shown in FIG. 9, the electronic component sealing structure 220 is disposed so as to span four sealing bases 222 disposed on the main control board 192 and above the four sealing bases 222. And a one-way screw 226 for making it impossible to remove the sealing lid 224 from the sealing base 222.

  The sealing base 222 has a substantially rectangular parallelepiped shape, and a screw hole 222a is formed on the upper surface of which a female screw that engages with a male screw of the one-way screw 226 is formed. Two sealing bases 222 are provided on the main control board 192 in the vicinity of both ends of the ROM 306 in the longitudinal direction. Further, the sealing base 222 is firmly fixed to the main control board 192 by rivets or other means so that it cannot be easily removed from the main control board 192.

  The sealing lid 224 has a substantially rectangular plate shape, and guard portions 224a that protrude downward are formed on both side surfaces of the central portion. Further, in the vicinity of the four corners of the sealing lid 224, insertion holes 224b through which the one-way screws 226 are inserted are formed. The guard portion 224a is for restricting unauthorized access to the ROM 306 from the side and preventing the sealing lid 224 from rotating around the one-way screw 226 inserted through the insertion hole 224b. The four insertion holes 224b are formed at positions corresponding to the screw holes 222a when the sealing lid 224 is disposed on the upper surface of the sealing base 222, respectively. In this embodiment, the sealing lid 620 is made of a transparent material.

  The one-way screw 226 is a screw (bolt) having a cross groove 226a formed in the head. The cross groove 226a is formed such that when the one-way screw 226 is inserted and a one-way screw 226 is inserted, the cross groove 226a can be turned in the direction in which the screw is fastened but cannot be turned in the direction in which the screw is loosened. ing. Specifically, the cross groove 226a has a sloped side surface that comes into contact with the tip of the plus driver 228 when the screwdriver 228 is turned in the direction of loosening the screw, and the tip of the plus driver 228 is crossed into the cross groove 226a. It is designed to be guided away from the direction. For this reason, it is impossible to remove the one-way screw 226 screwed with the sealing base 222.

  The ROM 306 is sealed by the electronic component sealing means 220 by screwing one one-way screw 226 with any one sealing base 222 through the insertion hole 224a of the sealing lid 224 and fastening the sealing lid 224 and the sealing base 222. Done. As described above, since the one-way screw 226 screwed to the sealing base 222 cannot be removed, the sealing lid 224 fastened to the sealing base 222 is at least one of the sealing base 222, the sealing lid 224, or the one-way screw 226. Unless any one of them is destroyed, it is impossible to separate from the sealing base 222. Further, since the guard portion 224a and the ROM 306 are in contact with each other, it is impossible to rotate the sealing lid 224 with the one-way screw 226 as a fulcrum and to shift it from above the ROM 306. As described above, removal of the ROM 306 from the main control board 192 is sealed.

  The seal is released by cutting the one-way screw 226 with a nipper or the like. Since the cut part of the one-way screw 226 remains in the screw hole 222a of the sealing base 222, it can be easily identified that the sealing has been released. Resealing is performed by screwing any one of the remaining three sealing bases 222 with a new one-way screw 226 and fastening the sealing lid 224 and the sealing base 222. Therefore, the electronic component sealing means 220 of the present embodiment can perform resealing three times.

The electronic component sealing structure 220 may be used for sealing electronic components (for example, the CPU 310) other than the ROM 306 disposed on the main control board 192, or may be disposed on another circuit board. You may make it use for the sealing of an electronic component.

To supply. Further, the power management unit 500 is a power storage device (for example, for supplying power to a predetermined part (for example, the RAM 308 of the main control unit 300) for a predetermined period (for example, 10 days) even after the power supply from the outside is cut off. Capacitor) and electric power supplied to a predetermined component (for example, the entire basic circuit 302 of the main control unit 300) is smaller than that of the power storage device, and is supplied to static electricity noise, human error, and a game table. The battery further includes a power storage device (for example, a capacitor) for supplementing a certain amount of power when the power fluctuates and decreases due to a decrease in power. With this power storage device, even if the power supplied to a predetermined component (for example, the main control unit 300) becomes unstable at the time of power interruption, power recovery, etc., the predetermined component can operate stably to some extent. It is composed. In addition, the power supply board constituting the power management unit 500 is provided with an operation unit (RAM clear switch) that can be operated by an amusement shop clerk and the operation unit is detected when the power is turned on. In this case, a RAM clear signal for instructing initialization of the RAMs 308 and 358 is output to the basic circuits 302 and 352 of each control unit.
<Data table of main control unit>

  Next, a data table stored in the ROM 306 of the main control unit 300 of the pachinko machine 100 will be described. The jackpot determination table shown in FIG. 12A is a data table in which the types of special drawing lotteries stored in the game state storage area provided in the RAM 308 and lottery data are stored in association with each other.

  The basic circuit 302 of the main control unit 300 uses this jackpot determination table to determine whether the special figure variation game is won (big hit) or not (miss), that is, jackpot determination. The special drawing lottery status information includes information indicating a low probability state in which the special figure variable game is determined to be won with a predetermined low probability, and high information for determining that the special figure variable game is selected with a higher probability than the low probability. Information including the probability state is included, and these are hereinafter simply referred to as a low probability state and a high probability state. Further, the information stored in the game state storage area includes other information, which will be described later.

  The lottery data in the jackpot determination table determines the result of the special figure variable game that starts when a predetermined ball detection sensor detects that a ball has won the first special figure start port 126 or the second special figure start port 128. It is lottery data used for For example, when the special drawing lottery state is in a low probability state and the acquired special figure winning random number value (random number will be described later) is 10001 to 10187, it is determined that the special figure variable game is won and provided in the RAM 308. In addition, information indicating that the jackpot flag is stored is set in the storage area for the jackpot flag (hereinafter, setting the jackpot information in the storage area for the jackpot flag is referred to as “setting the jackpot flag on”). On the other hand, if the acquired special figure winning random number is a value other than 10001 to 10187, it is determined that the special figure variable game is out and information indicating that it is out of the storage area for the jackpot flag is set. (Hereinafter, setting outlier information in the jackpot flag storage area is referred to as “setting the jackpot flag off”). In this embodiment, the numerical range that can be taken by the special figure winning random number is 0 to 65535 (the numerical range is 65536), and the numerical range indicated by the lottery data in the low probability state is 10001 to 10187 (the large numerical range). Therefore, the winning probability of the special figure variable game based on the winning of the ball to the first special figure starting port 126 or the second special figure starting port 128 in the low probability state is about 1 / 350.4 ( = 187/65536). On the other hand, the numerical range indicated by the lottery data in the high probability state is 20001 to 211871 (the size of the numerical range is 1871), so the first special figure start port 126 or the second special figure start port in the high probability state. The winning probability of the special figure variable game based on the winning of the ball to 128 is about 1 / 35.0 (= 1871/65536), and the winning probability of the special figure variable game is higher in the higher probability state than in the low probability state. Is set to be high.

  The high-probability state transition determination table shown in FIG. 12B is a data table that stores lottery data used when it is determined that the jackpot is determined as a result of the jackpot determination.

  The basic circuit 302 of the main control unit 300 uses this high probability state transition determination table to determine whether to start a jackpot game or a special jackpot game after the end of the special figure variable game, that is, a probability change transition determination. I do. For example, when the acquired special figure random number value (the random number value will be described later) is a numerical value of 11 to 74, the probability change (probability fluctuation) flag storage area provided in the RAM 308 is stored in the storage area of the special figure fluctuation game. Information indicating that the special jackpot game is started is set (here, setting the special jackpot game start information in the storage area for the probability change flag is referred to as turning on the probability change flag). On the other hand, if the acquired special figure random number value is other than the numerical values of 11 to 74, information indicating that the jackpot game is started is set in the above-described probability variation flag storage area (where the probability variation flag is stored). Setting the jackpot game start information in the area is referred to as setting the probability variation flag off). In the present embodiment, the range of numerical values that can be taken by the special figure random number value is 0 to 127 (the size of the numerical range is 128), and the range of random numbers for determining the migration of the lottery data is 11 to 74 (the size of the numerical range is 64). Therefore, when the result of the jackpot determination is winning, the probability of winning the result of the probability change transition determination, that is, the probability of starting the special jackpot is 1/2 (= 64/128).

  The timer number determination table shown in FIG. 12 (c) is a timer that indicates the above-mentioned jackpot flag, lottery data, and variable time from when the special figure display device 114 starts displaying the special figure to the stop display. It is the data table which matched and memorize | stored the number.

The basic circuit 302 of the main controller 300 determines the timer number based on the timer number determination table, the above jackpot determination result (the value of the jackpot flag), and a special-purpose timer random number value described later (the random number value will be described later). Select. For example, when the jackpot flag is off and the acquired special figure timer random number value is a numerical value from 0 to 60235, the timer number is selected as the timer number 1 (fluctuation time 5 seconds), the jackpot flag is turned on and acquired. When the special figure timer random number is a numerical value of 0 to 15535, timer 2 (variation time 10 seconds) is selected as the timer number. In this embodiment, the numerical value range that can be taken by the special-purpose timer random number value is 0 to 65535 (the numerical value range is 65536). If the above-mentioned jackpot determination result is incorrect, the timer 1 timer random number range 0 to 60235 (the numerical range has a size of 60236), the probability of selecting timer 1 (fluctuation time 5 seconds) as the timer number is 60236/65536. As the timer number, the probability of selecting timer 2 (variation time 10 seconds) is 4250/65536, the probability of selecting timer 3 (variation time 20 seconds) is 800/65536, and timer 3 (variation time 40 seconds) is selected. The probability of doing is 250/65536. On the other hand, if the jackpot determination result is winning, the timer random number range of timer 2 is 0 to 15535 (the numerical value range is 15536), so the probability of selecting timer 2 (variation time 10 seconds) as the timer number Is 15535/65536. As the timer number, the probability of selecting timer 3 (variation time 20 seconds) is 9000/65536, the probability of selecting timer 4 (variation time 40 seconds) is 38000/65536, and timer 5 (variation time 50 seconds) is selected. The probability of doing is 3000/65536.
<Main control unit reset interrupt processing>

  Next, a main control unit reset interrupt process executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of main controller reset interrupt processing.

  As described above, the main control unit 300 is provided with the start signal output circuit that outputs the start signal when the power is turned on. The CPU 304 of the basic circuit 302 to which this activation signal is input starts resetting by a reset interrupt and executes processing in accordance with a control program stored in advance in the ROM 306. First, various initial settings are performed in step S101. In this initial setting, initial setting of input / output ports, initialization of various variables, processing for setting a numerical value for determining a cycle for executing a main control unit timer interrupt processing, which will be described later, to the counter timer 312 and the like are performed.

  In step S102, it is determined whether or not the RAM 308 stores return data (data storing information for returning the control state at the time when the power was previously turned off). If the return data is stored in the RAM 308, the process proceeds to step S103. If not, the process proceeds to step S104.

  In step S103, the return data is used to return to the state before the power is shut off.

In step S104, the software random number counter is updated. Here, in order to generate two initial value generation random number counters for generating the initial values of the common figure winning random number counter and the special figure random number counter, and the common figure timer random number value and the special figure timer random number value, respectively. 2 random number counters are updated. For example, if the range of values that can be taken as normal timer random numbers is 0 to 20, a value is acquired from a random number counter storage area for generating a normal timer random value provided in the RAM 308, and 1 is added to the acquired value. Then, it is stored in the original random number counter storage area. At this time, if the result of adding 1 to the acquired value is 21, 0 is stored in the original random number counter storage area. Other initial value generation random number counters and random number counters are updated in the same manner. The main control unit 300 repeatedly executes the process of step S104 except during the main control unit timer interrupt process starting at predetermined intervals.
<Main controller timer interrupt processing>

  Next, main control unit timer interrupt processing executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of main controller timer interrupt processing.

  The main control unit 300 includes a counter timer 312 that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 2 ms), and triggers the main control unit timer interrupt processing at a predetermined cycle. Start.

  In step S <b> 201, the value of the input port of the I / O 310 is acquired and the state of the various sensors 318 is detected. For example, a signal from a sphere detection sensor that outputs an ON signal when it is detected that a sphere has entered the first and second special figure starting ports 126 and 128 is input. Signals from the corresponding ball detection sensors are also inputted to other prize winning openings, starting openings and the like. The result input in step S201 is stored in a signal state storage area provided for each sensor in the RAM 308.

  In step S202, the software random number counter is updated. Here, two random number counters for generating the special-purpose winning random number value and the special-purpose random number value used in the main control unit 300, and the above-mentioned general-purpose winning random value and the initial value of the special-purpose random number value are respectively shown. Two initial value generation random number counters for generation are updated. For example, if the range of values that can be taken as a random number value for a normal winning number is 0 to 100, a value is acquired from a random number counter storage area for generating a normal winning random number value provided in the RAM 308 and 1 is added to the acquired value. Then, it is stored in the original random number counter storage area. At this time, if the result of adding 1 to the acquired value is 101, 0 is stored in the original random number counter storage area. If it is determined that the random number counter has made one round as a result of adding 1 to the acquired value, the value of the initial value generating random number counter corresponding to each random number counter is acquired and stored in the storage area of the random number counter. set. For example, a value is acquired from a random number counter for generating a regular winning random number that fluctuates in a numerical range of 0 to 100, and a result obtained by adding 1 to the acquired value is stored in a predetermined initial value storage area provided in the RAM 308. If the value is equal to the previously set initial value (for example, 7), the value is acquired as an initial value from the initial value generation random number counter corresponding to the random number counter for generating the random number for winning the normal number, The initial value set this time is stored in the above-described initial value storage area in order to determine that the random number counter for generating the winning random number value has made one round next time, in addition to setting it in the random number counter for generating the winning random value Keep it. After these processes, the value of the initial value generation random number counter performed in step S104 is updated. In addition to the above-described initial value storage area for determining that the random number counter for generating the regular-winning random number next makes one round, it is determined that the random number counter for generating the special figure random number has made one round. An initial value storage area is provided in the RAM 308.

  In step S203, winning detection is performed based on the state of the signals input from the various sensors in step S201 described above. In this winning detection, if there is a winning (winning) at the winning opening or starting opening (general winning opening 122, first and second special figure starting openings 126, 128 and variable winning opening 130), it is provided in the RAM 308. The number of prize balls determined in advance for each prize opening is added to the value of the prize ball number storage area, or there is a prize at the first special figure starting port 126 or the second special figure starting port 128, and is held. When the special figure variable game number is less than 4, a value is acquired as a special figure winning random number value from the counter value storage register of the counter circuit 316b corresponding to the winning start port. In addition, a value is acquired as a special figure random value from the random number counter for generating the special figure random value described above, and stored in a random value storage area provided in the RAM 308 together with the special figure winning random number value. In addition, when it is detected that the ball has passed through the general figure starting port 124, and the number of the general figure variable games held is less than two, the random number counter for generating the normal figure winning random number value at that timing Is acquired as a random number value for winning a normal figure and stored in a random number value storage area provided in the RAM 308 different from that for the special figure.

  In step S204, a process related to a special figure variable game (a special figure related process) is performed. In this special figure related process, when the special figure variable game and the variable winning a prize opening 130 are not controlled, and the number of the special figure variable games held is one or more, the main control unit 300 Of the various lotteries using the above-described various data tables to be stored, the jackpot determination is first performed.

  Specifically, it is determined whether or not the special figure winning random number value stored in the random value storage area in step S203 is within the numerical range of the lottery data in the jackpot determination table shown in FIG. When the random value is within the numerical range of the lottery data, it is determined that the special figure variable game is won and the jackpot flag is set to ON. On the other hand, when the special figure winning random number value is outside the numerical value range of the lottery data, it is determined that the special figure variable game is out and the jackpot flag is set to OFF. For example, if the special drawing lottery state is in a low probability state and the special figure winning random number value acquired based on the detection of the ball winning at the first special figure starting port 126 or the second special figure starting port 128 is 10100, The jackpot flag is set to ON because the figure winning random number value is in the range of 10001 to 10187, and when the special figure winning random number value is 10300, the special winning prize random number value is outside the range of 10001 to 10187. Set the flag off.

  If the jackpot flag is set to ON, then the probability variation transition determination is performed. Specifically, it is determined whether or not the special figure random value stored in the random value storage area in step S203 is within the numerical range of the transition determination random number shown in FIG. In the case of the numerical value range, the probability variation flag is set to ON, and in the case where the special figure random number value is outside the numerical range of the lottery data, the probability variation flag is set to OFF. For example, when the acquired special figure random number value is 20, since the special figure random number value is in the range of 11 to 74, the probability variation flag is set to ON. On the other hand, when the acquired special figure random number value is 80, the probability change flag is set to OFF because the special figure random number value is outside the range of 11 to 74.

  Regardless of the result of the jackpot determination, the process for determining the timer number is performed next. Specifically, the value of the random counter for generating the special figure timer random value described above is acquired as the special figure timer random value. Then, based on the value of the jackpot flag and the acquired special figure timer random number value, the timer number corresponding to the numerical range of the timer selection random number shown in FIG. 12C is selected, and the timer number storage area provided in the RAM 308 is selected. Remember. Further, the variation time corresponding to the timer number is stored in the variation time storage area provided in the RAM 308, and the process is terminated. For example, when the jackpot flag is off and the acquired special figure timer random number value is 50000, the special figure timer random number value is in the range of 0 to 60235, and therefore 1 corresponding to those conditions of the timer number determination table. The timer 1 indicating the timer number stored in the line and 5 indicating the variation time are selected and stored in the respective storage areas provided in the RAM 308. On the other hand, when the jackpot flag is on and the acquired special figure timer random number value is 64000, the special figure timer random number value is not in the range of 0 to 15535, so the timer 2 is not selected and is not 15536 to 24535. Timer 3 is not selected, and timer 4 is not selected because it is not 24536 to 62535. However, since it is within the range of 62536 to 65535, it is stored in the eighth line corresponding to those conditions in the timer number determination table. The timer 5 indicating the timer number and the variable time 50 are selected and stored in the respective storage areas provided in the RAM 308. In consideration of 2 ms which is the start cycle of the main control unit timer interrupt processing, a value obtained by multiplying the selected variation time value by 500 (1000 ms / 2 ms) is set in the variation time storage area. For example, when 5 seconds is selected as the variation time, a value of 2500 is set as an initial value in the variation time storage area, and this variation time storage area is executed every time a timer update process (step S208) described later is executed. By subtracting 1 from this value, the passage of time can be measured by the number of executions of the main control unit timer interrupt process.

  Further, in the special figure fluctuation-related processing that starts at the timing when the value of the fluctuation time storage area is changed from 1 to 0, the special figure display device 114 displays the special figure 1 or the special figure 2 when the jackpot flag is on. When the jackpot flag is off, the special figure 3 is set to be displayed, and thereafter, the display is set to be maintained for a predetermined stop display period (for example, 500 msec). With this setting, the special figure is stopped and displayed, and the result of the special figure variable game is notified to the player.

  That is, the “special symbol (special diagram) variable game” in this embodiment is when the predetermined ball detection sensor detects that a ball has won the first special diagram start port 126 or the second special diagram start port 128. The special figure winning random number value and the special figure random number value are acquired in the winning detection process in step S203, and the acquired values are respectively stored in the predetermined storage areas of the RAM 308, and in the special figure related process in step S204. The value of the random number counter stored in a predetermined storage area of the RAM 308 is acquired as a special figure timer random number value, and a jackpot is determined based on the special figure winning random number value stored in the predetermined storage area of the RAM 308. Probability variation is determined based on the special figure random number value stored in a predetermined storage area, and special figure fluctuation is based on the jackpot determination result and the acquired special figure timer random value. The special figure is variably displayed over the fluctuation time, and the stop display of the special figure 1, the special figure 2 or the special figure 3 determined based on the above jackpot determination result and the determination of the probability fluctuation. To finish.

  Also, in the special figure fluctuation-related processing that starts at the timing when the predetermined stop display period ends, when the jackpot flag is on, a predetermined winning effect period (for example, 3 seconds), that is, a big win by the decorative symbol display device 110 is started. It sets so that it may wait for the period which is displaying the image which alert | reports to a player to do.

  Further, in the special figure fluctuation-related processing that starts at the timing when the predetermined winning effect period ends, a predetermined number of gaming balls (for example, ten balls) are awarded to a predetermined opening period (for example, 29 seconds or the variable winning opening 130). It sets so that the signal which hold | maintains a door member in an open state may be output to the solenoid 330 for the opening / closing drive of the door member of the variable prize opening 130 until it detects.

  Further, in the special figure fluctuation-related processing that starts at the timing when the predetermined opening period ends, the door member is attached to the solenoid 330 for opening and closing the door member of the variable winning opening 130 for a predetermined closing period (for example, 1.5 seconds). It is set to output a signal that is held in the closed state.

  In the special figure variation-related processing that is started at the timing when the opening / closing control of the door member is repeated a predetermined number of times (for example, 15 rounds), a predetermined end effect period (for example, 3 seconds), that is, a big hit by the decorative symbol display device 110 is received. It sets so that it may wait for the period which is displaying the image which alert | reports to a player that it complete | finishes.

  Also, in the special figure fluctuation-related processing that starts at the timing when the predetermined end effect period ends, if the number of special figure fluctuation games that are pending is one or more, the next special figure fluctuation game such as the jackpot determination described above is executed. Start. The number of special figure variable games that are held is stored in the special figure hold number storage area provided in the RAM 308, and the number of special figure variable games that are held every time a big hit determination is made. The value obtained by subtracting 1 is stored again in this special figure reservation number storage area.

  In step S205, a process related to a general map variable game (a general map related process) is performed. In this general map-related process, when the open / close control of the general map variable game and the second special figure start port 128 is not performed, and the number of the general map variable games held is 1 or more, Make a hit judgment.

  Specifically, it is determined whether or not the winning random number value stored in the random value storage area in step S203 is within the numerical range of the lottery data in the predetermined determination table. If it is in the numerical range, it is determined that the normal game is won and the winning flag is set to ON. On the other hand, when the usual winning random number is outside the numerical value range of the lottery data, it is determined that the usual figure variable game is out of play and the winning flag is set to OFF.

  Regardless of the result of the hit determination, processing for determining the timer number is performed next. Specifically, the value of the random number counter for generating the normal timer random number described above is acquired as the normal timer random value. Then, a timer number is selected based on the number of reserved balls in the usual game and the obtained ordinary timer random number value, and stored in a timer number storage area provided in the RAM 308. Further, the variation time corresponding to the timer number is stored in the variation time storage area provided in the RAM 308, and the process is terminated.

  Further, in the common figure-related processing that starts at the timing when the value of the above-mentioned variable time storage area for normal maps is changed from 1 to 0, when the hit flag is on, the normal map display device 112 displays the above-mentioned common figure. 1. When the hit flag is off, the setting is made so as to display the above-mentioned FIG. 2, and thereafter, the display is set to be maintained for a predetermined stop display period (for example, 500 msec). With this setting, the usual figure is stopped and the result of the usual figure variable game is notified to the player.

  That is, the “ordinary symbol (ordinary figure) variable game” in the present embodiment is performed in the winning detection process in step S203 when a predetermined ball detection sensor detects that a ball has won a prize in the ordinary figure starting port 124. The figure winning random number value is acquired and the acquired value is stored in a predetermined storage area of the RAM 308, and the value of the random number counter stored in the predetermined storage area of the RAM 308 in the routine related processing in step S205 is obtained. It is acquired as a general-purpose timer random number value, a hit determination is made based on a general-purpose winning random number value stored in a predetermined storage area of the RAM 308, and a normal time fluctuation time based on the determination result and the acquired general-purpose timer random number value The base map is variably displayed over the change time, and the stop display of the base map 1 or base map 2 determined based on the hit determination result described above is performed and the process ends.

  Further, in the common figure-related processing that starts at the timing when the predetermined stop display period ends, when the hit flag is on, the blades of the second special figure starting port 128 are opened and closed for a predetermined opening period (for example, 2 seconds). The drive solenoid 330 is set to output a signal for holding the blades in an open state.

  Further, in the common figure-related processing which starts at the timing when the predetermined opening period ends, a signal for holding the blades in the closed state is output to the solenoid 330 for opening and closing the blades of the second special figure starting port 128. In addition to the setting, the solenoid 330 for opening / closing driving is set to hold the closed state of the blades for a predetermined closing period (for example, 500 msec).

  Also, in the general chart-related processing that starts at the timing when the predetermined closing period has passed, when the number of pending general chart variable games is 1 or more, the next common figure variable game such as the above hit determination process is started. To do. In addition, the number of pending general figure variable games is stored in the usual figure pending number storage area provided in the RAM 308, and from the number of pending custom figure variable games each time a hit determination is made. The value obtained by subtracting 1 is re-stored in the usual figure number-of-holds storage area.

  In step S206, a control command (effect command) is transmitted to effect control unit 350. The control command includes a change start command that is transmitted when the jackpot determination is made in step S204, a change stop command that is transmitted when the value of the change time storage area is 1 to 0, and a jackpot. There are a jackpot start command to be transmitted when the jackpot flag is set in the determination, round start information to be transmitted at each start of the predetermined release period, etc., and the variation start command has a variation time (for example, a selected timer number). ), Probability variation flag on / off information, jackpot flag on / off information, etc., and the round start command includes information indicating the number of times the variable winning opening 130 is opened after the jackpot is started (for example, the number of rounds) ) Etc. Also, a payout command is transmitted to the payout control unit 400. This payout command includes the number of prize balls based on the value of the prize ball number storage area described above.

  In step S207, the various solenoids 330 are driven to control the opening / closing of the second special figure starting port 128 and the variable winning port 130, and the game information stored in the RAM 308 is sent to the pachinko machine via the information output circuit 334. 100 is output to an information input circuit 550 that is separate from 100. In addition, display data to be output to the general-purpose display device 112, the special-purpose display device 114, various status display units 326, and the like via the display circuits 322, 324, and 328 is set in the output port of the I / O 310.

  In step S208, the normal symbol display device 112 and the special symbol display device 114 measure the time for changing / stopping the symbols, the predetermined winning effect time, the predetermined opening time, the predetermined closing time, the predetermined end effect period, and the like. Various timers including timers for updating are updated.

  In step S209, the voltage monitoring circuit that monitors the voltage value of the power source supplied from the power management unit 500 to the main control unit 300 outputs a voltage drop signal indicating that the voltage has dropped when the voltage value is equal to or lower than a predetermined value. Whether or not a power-off is detected. If a power-off is detected, a specific variable or stack pointer for returning to the power-off state at the time of power recovery is displayed. The return data is saved in a predetermined area of the RAM 308, and power interruption processing such as initialization of the input / output port is performed.

  As described above, the sealing structure 210 according to the present embodiment includes the engaging member 212 and the engaged member 214 configured to be able to engage with each other at the engaging position, and at least the engaging member 212 or the engaged member. Either one of the members 214 is integrally formed with an engagement obstructing portion 212e that obstructs the mutual engagement. When the engagement obstructing portion 212e is removed, the engagement member 212 and the engaged member 214 are disengaged. Engagement is possible, and at least one of the engagement member 212 and the engaged member 214 is configured to be disengageable unless at least one of them is destroyed. For this reason, it is possible to easily seal when it is necessary to seal, while preventing erroneous sealing when it is not necessary to seal. In addition, since the engagement blocking portion 212e is formed integrally with the engagement member 212, the engagement blocking portion 212e is not lost, so that erroneous sealing can be reliably prevented. Furthermore, by forming the engagement blocking portion 212e integrally with the engagement member 212, the number of parts can be reduced, and the manufacturing cost can be reduced.

  Further, the engaging member 212 includes a contact surface 212g, and the engaged member 214 cannot contact the engaging surface 212g to release the engagement of the engaging member 212 and the engaged member 214. The engagement obstructing portion 212e is in contact with the engagement member 212 or a part of the engagement member 214 when the engagement member 212 and the engagement member 214 are in the engagement position. By contact, at least one of the contact surface 212g and the contacted surface 214f is formed at a position where it cannot contact each other. For this reason, without adopting a complicated mechanism or structure, it is possible to reliably perform sealing with a simple and inexpensive configuration, and reliably prevent sealing when necessary.

  Note that the engagement obstructing portion 212e contacts the contacted surface 214f by contacting a part of the engaged member 214 when the engaging member 212 and the engaged member 214 are in the engaged position. The engaging member 212 is preferably formed so as to be disposed at a position where it cannot contact the surface 212g.

  Further, when the engagement member 212 and the engaged member 214 are in the engaged position, the engagement obstructing portion 212e contacts the part of the engagement member 212 so that the contacted surface 214f is brought into contact with the contact surface. It may be formed on the engaged member 214 so as to be disposed at a position where it cannot contact 212g.

  Further, the engagement obstructing portion 212e includes a rupture portion (connection portion in this embodiment) 212f that is broken when it is removed, and the rupture portion 212f includes the engagement member 212 and the engaged member 214 that are mutually connected. It is formed so that a fractured surface is formed on a surface other than the surfaces (in this embodiment, the contact surface 212g and the contacted surface 214f) that cannot be released from engagement. For this reason, the contact surface 212g and the contacted surface 212f can always be properly contacted without being affected by the state of the fracture surface of the fractured portion 212f. Therefore, the sealing can be ensured.

  The sealing structure 210 further includes a cover that covers the engaging member 212 and the engaged member 214 at the engaging position, and the cover is a first cover member that is formed integrally with the engaging member 212 (this embodiment). In the example, it is composed of a base end portion 212a and a tip end portion 212d), and a second cover member (in this embodiment, an outer wall portion 214b) formed integrally with the engaged member 214, and the first cover member and When the engaging member 212 and the engaged member 214 are in the engaging position, the second cover member has an opening formed in either the first cover member or the second cover member (in this embodiment, The insertion hole 214d and the molding hole 214g) are blocked by a blocking portion (in the present embodiment, the base end portion 212a and the tip end portion 212d) formed on either the first cover member or the second cover member. It is formed so as to. For this reason, the engaging portions of the engaging member 212 and the engaged member 214 (the abutting surface 212g and the abutting surface 214f) can be covered almost completely, so that the outside cannot be contacted. Therefore, it is possible to prevent the sealing from being skillfully released from the outside, and to ensure the sealing.

  Further, the engagement blocking portion 212 is formed such that a portion that contacts the engaging member 212 or the engaged member 214 is thicker than the other portions. For this reason, it is possible to increase the strength of the engagement obstructing portion 212, and even when the engagement member 212 and the engaged member 214 are repeatedly approached and separated from the engagement position when sealing is not performed, It is possible to prevent the obstructing portion 212e from being worn or deformed. Accordingly, it is possible to prevent the seal from being sealed due to wear or deformation of the engagement disturbing portion 212e even though the engagement disturbing portion 212e is not removed.

  The sealing structure 210 according to the present embodiment is suitable for use in sealing a board case that houses a circuit board of a game machine, and particularly suitable for use in sealing a board case that houses a control board. It is.

  In this embodiment, the engaging member 212 and the engaged member 214 are configured to be able to engage with each other at the engaging position, and at least one of the engaging member 212 and the engaged member 214 includes An engagement obstruction portion 212e that obstructs the mutual engagement is provided, and when the engagement obstruction portion 212e is removed, the engagement member 212 and the engaged member 214 can be engaged, and at least the engagement member A plurality of sealing structures 210 configured to be disengaged unless one of 212 and the engaged member 214 is broken are provided. For this reason, even after the seal is released based on a valid reason, the seal can be performed again.

  In addition, at least one of the plurality of sealing structures 210 has the engagement blocking portion 212e removed in advance. For this reason, when sealing for the first time, it is not necessary to remove the engagement obstruction part 212e, and it can seal easily and speedily.

  Further, the engagement blocking portion 212e is formed integrally with the engagement member 212 or the engaged member 214. As a result, the engagement obstructing portion 212e is not lost or the sealing structure 210 to be engaged this time among the plurality of sealing structures 210 is not mistaken, so that erroneous sealing can be reliably prevented. . Further, the manufacturing cost can be reduced by reducing the number of parts.

  In some cases, sealing is performed with two sealing structures 210 at the time of one-time sealing. In the present embodiment, it has been described that three sealing structures 210 are prepared and three sealing operations are possible. However, six sealing structures 210 may be prepared to enable three sealing operations. . In this case, since the sealing is performed at two places at the time of the first sealing, the sealing structure 210 from which the engagement disturbing portion 212e is removed in advance may be two places. As described above, there may be a plurality of sealing structures 210 from which the engagement blocking portions 212e are removed in advance.

  Moreover, when performing sealing with a plurality of sealing structures 210 by one sealing, an identification display for indicating the sealing structures 210 that are set may be displayed. For example, if six sealing structures 210 are prepared and three sealing operations are planned, the number “1” is displayed on the two sealing structures 210 used in the first sealing operation, and the second sealing operation 210 is performed. The number “2” may be displayed on the two sealing structures 210 used in the sealing work, and the number “3” may be displayed on the two sealing structures 210 used in the third sealing work. This means that the two sealing structures 210 displaying the number “1” are “two sealing structures used for the first time”, and the two sealing structures 210 displaying the number “2” are displayed. Means “two seal structures used for the second time”, and two seal structures 210 with the number “3” displayed mean “two seal structures used for the third time”. ing.

  Thus, by providing either one or both of the information indicating the order of the sealing structure 210 used for sealing and the information indicating the combination of the sealing structures 210 used for one sealing, the sealing structure There is an effect that an operator who performs sealing by 210 can easily understand which sealing structure 210 is used for sealing. In the case where a plurality of sealing structures 210 are provided and sealing is performed with one sealing structure 210 at the time of one sealing, only information indicating the order of the sealing structures used for sealing may be displayed. Good. Further, among the information indicating the order of the sealing structure used at the time of sealing, such as “1”, the sealing structure 210 to which information indicating that the sealing structure is used first is removed in advance from the engagement blocking portion 212e. It may be. In addition, information indicating the order of the sealing structure 210 or information indicating a combination of the sealing structures 210 used for one sealing is generally displayed on the base case 200 or the sealing structure 210. However, the present invention is not limited to this. For example, it may be displayed on any of the game components constituting the game table, such as displaying on the circuit board 192.

Further, the pachinko machine 100 according to the present embodiment includes a circuit board (main control board in this embodiment) 192 on which a predetermined circuit pattern is formed, and electronic components (this embodiment) disposed on the circuit board 192. In this case, the electronic component 306 disposed on the circuit board 192 is sealed on the circuit board 192. When the electronic component 306 is removed from the circuit board 192, a trace is left and the electronic component 306 is re-applied a predetermined number of times. And an electronic component sealing structure 220 configured to be sealable. The electronic component sealing structure 220 includes a sealing base 222 that is fixed to the circuit board 192 with a screw hole 222a that is screwed with the one-way screw 226, and an insertion hole 224a through which the one-way screw 226 is inserted. A sealing lid 224 covering at least a portion, and sealing is performed by fastening the sealing base 222 and the sealing lid 224 with a one-way screw 226,
The electronic component 306 is configured to be removable from the circuit board 192 when any component constituting the electronic component sealing means 220 is destroyed.

  Conventionally, if a part of a cover that seals an electronic component such as an IC is broken and the electronic component is removed, it cannot be reused, so whether or not an amusement store has been replaced with an illegal electronic component. Even when it is desired to check an electronic component for a legitimate purpose such as confirmation, it is necessary to prepare a new cover or the like, and the electronic component cannot be easily checked. On the other hand, since the electronic component sealing structure 220 according to the present embodiment is configured to be resealable a predetermined number of times (three times in this embodiment), the electronic component seal is released for a legitimate purpose. Sealing can be performed again later.

Next, a second embodiment of the present invention will be described. The pachinko machine according to the present embodiment is obtained by applying a sealing structure 230 to the pachinko machine 100 according to the first embodiment, instead of the sealing structure 210, and other structures and processes are the same as those of the first embodiment. . For this reason, the same portions are denoted by the same reference numerals in the drawings, the description thereof is omitted, and only the sealing structure 230 will be described below.
<Sealing structure>

  FIG. 15A is a front view of the substrate case 200, and FIG. 15B is an enlarged view of a G portion of FIG. The substrate case 200 of this embodiment includes three sealing structures 230 and can be sealed three times. The sealing structure 230 includes an engaging member 232 integrally formed on the upper portion of the lower lid 202 and an engaged member 234 formed integrally on the upper portion of the upper lid 204. In a state where the lower lid 202 and the upper lid 204 are coupled, most of the engaging member 232 of the sealing structure 230 is inserted into the engaged member 234. In this state, the engaging member 232 and the engaged member 234 are in a state in which they can be engaged with each other, and are located at the engaging positions in the present invention.

  FIGS. 16A and 16B are views showing the structure of the engaging member 232. 16 (a) is a view in the direction of arrow A in FIG. 4 (a), and FIG. 16 (b) is a perspective view of FIG. 16 (a). The engaging member 232 includes a base end portion 232a that protrudes upward from the upper portion of the lower lid 202, and an insertion portion 232b that protrudes from the base end portion 232a toward the upper lid 204. The base end portion 232 a is a plate-like member that is integrally connected to the lower lid 202. The insertion portion 232b is a plate-like member in which two substantially H-shaped openings 232c are formed. A distal end portion 232d having a substantially rectangular parallelepiped shape that closes the opening of the engaged member 234 protrudes from the distal end of the insertion portion 232b.

  A substantially rectangular parallelepiped engagement blocking portion 232e is formed between the two openings 232c formed in the insertion portion 232b. The engagement obstruction part 232e is integrally connected to the insertion part 232b via two connection parts 232f formed on the distal end side and the proximal end side of the insertion part 232b, respectively. The two connection portions 232f are formed thinner (smaller in cross-sectional area) than the engagement blocking portion 232e. A groove 232g is formed in the left-right direction on the upper surface of the engagement obstructing portion 232e, and the side surface of the groove on the distal end side of the insertion portion 232b is a guide surface 232h formed in an inclined shape. The side edges of the two openings 232c protrude inward in the vicinity of the engagement blocking portion 232e, and the surface of the protruding portion on the base end side of the insertion portion 232b is a contact surface 232i. In the present embodiment, the engagement member 232 on the right side of the drawing is in a state where the engagement obstruction part 232e has been removed in advance.

  FIGS. 16C to 16E are views showing the structure of the engaged member 234. 16C is a view in the direction of arrow B in FIG. 4A, FIG. 16D is a cross-sectional view taken along line JJ in FIG. 15B, and FIG. It is a perspective view of 16 (d). The engaged member 234 includes two legs 234a provided on the upper portion of the upper lid 204, an outer wall 234b provided above the legs 234a, and a tongue piece 234c provided inside the outer wall 234b. Has been. The leg portion 234a is a short bar-like member that is integrally connected to the upper lid 204, and is a portion that is cut when the seal is released. The outer wall portion 234b is a box-like member having an opening on the lower lid 202 side, and this opening portion serves as an insertion hole 234d into which the engaging member 232 is inserted. The tongue piece 234c is a plate-like member protruding from the inner surface of the outer wall portion 234a opposite to the insertion hole 234d. A protruding portion 234e having a saw-tooth cross section protruding downward is formed at the distal end portion of the tongue piece 234c, and the vertical surface of the protruding portion 234e on the base end side of the tongue piece 234c is abutted against the engaging member 232. The contact surface 234f is in contact with the contact surface 232d. Further, a molding hole 234g necessary for molding the protruding portion 234e is formed in the outer wall portion 234b above the base end of the tongue piece 234c.

  17A is a cross-sectional view taken along the line HH in FIG. 15B, and FIGS. 17B and 17C are cross-sectional views taken along the line II in FIG. 15B. FIG. 17A shows a case where the engaging member 232 from which the engagement blocking portion 232e has been removed in advance and the engaged member 234 are in the engaged position. In this case, the insertion portion 232b of the engaging member 232 is accommodated in the outer wall portion 234b of the engaged member 234, and the distal end portion 232d at the distal end of the insertion portion 232b is accommodated in the molding hole 234g of the engaged member 234. It has become a state. And the protrusion part 234e of the tongue piece 234c front-end | tip of the to-be-engaged member 234 is the state fitted and engaged in the inside of the opening part 232c formed in the insertion part 232b of the engagement member 232. In this state, even if the engaged member 234 is moved away from the engagement position (upward in the figure), the contact surface 232 i of the engagement member 232 and the contact surface 234 f of the engaged member 234 Therefore, it is impossible to move the engaged member 234 unless at least one of the engaging member 232 and the engaged member 234 is destroyed. That is, the substrate case 200 is sealed by the sealing structure 230.

  Further, when the engaging member 232 and the engaged member 234 are respectively in the engaged position, they are shielded by the outer wall portion 234b of the engaged member 234, the base end portion 232a and the distal end portion 232d of the engaging member 232. Therefore, it is impossible to contact the insertion portion 232b or the tongue piece 234c from the outside.

  In the present embodiment, unlike the first embodiment (see FIG. 7), the elastic deformation direction of the tongue piece 234c is the outer direction of the sealing structure 210 (the direction toward the opposite side of the upper lid 204). This is because, when an attempt is made to destroy part of the outer wall portion 234b for an unauthorized purpose and to forcefully deform the tongue piece 234c with a wire or the like, the elastic deformation direction of the tongue piece 234c is a sealing structure as shown in FIG. Assuming that the direction is the inner side of 210 (the direction toward the upper lid 204), the cheating person can release the seal only by pressing the tongue 234c with a wire or the like. However, with the configuration of the present embodiment, even if a part of the outer wall portion 234b is destroyed for an unauthorized purpose, it is difficult to release the seal because the elastic deformation direction is the pulling direction. The configuration of this embodiment may be applied to the first embodiment.

  On the other hand, FIG. 17B shows a case where the engaging member 232 including the engaging blocking portion 232e and the engaged member 234 are in the engaged position. Also in this case, the insertion portion 232b of the engaging member 232 is accommodated inside the outer wall portion 234b of the engaged member 234, and the distal end portion 232d at the distal end of the inserting portion 232b is in the molding hole 234g of the engaged member 234. It is in a state of being accommodated in. And the protrusion part 234e of the tongue piece 234c front-end | tip of the to-be-engaged member 234 is in the state accommodated in the groove | channel 232f of the engagement obstruction | occlusion part 232e. From this state, when the engaged member 234 is moved in a direction away from the engagement position (upward in the drawing), the tip of the protrusion 234e contacts the guide surface 232h, and the contacted surface along the guide surface 232h. It moves in a direction away from 234f (left side of the figure). In other words, the guide surface 232h of the engagement disturbing portion 232e causes the contacted surface 234f to contact the contact surface while pressing the protruding portion 234e and elastically deforming the tongue piece 234c as the engaged member 234 moves. It is guided to a position where it cannot contact 232i.

  FIG. 17C shows a state after the contacted surface 234f is guided to a position where it cannot contact the contact surface 232i. When the engaged member 234 is further moved away from the engagement position from this state, the protruding portion 234e remains along the engagement blocking portion 232e and the connection portion 232f while the tongue piece 234c remains elastically deformed. Since it moves, the engaging member 232 and the engaged member 234 can be separated. Thus, in this embodiment, when the engagement member 232 includes the engagement obstruction part 232e, the engagement member 232 and the engaged member 234 can be separated from the engagement position. The sealing by the sealing structure 230 is not performed.

  In this embodiment, the substrate case 200 is provided with three sealing structures 230, and the engagement member 232 of the two sealing structures 230 among them is provided with the engagement disturbing portion 232e, so that resealing is performed twice. It is possible. FIGS. 18A to 18D are diagrams showing a procedure for resealing. In these drawings, the sealing structure 230 on the right side of the figure is obtained by removing the engagement blocking portion 232e in advance, and the sealing structure 230 on the left side and the center of the drawing includes the engagement blocking portion 232e. . Therefore, when the lower lid 202 and the upper lid 204 are first combined, sealing is performed by engaging the engaging member 232 and the engaged member 234 of the sealing structure 230 on the right side of the drawing. In order to release the seal from this state, the leg 234a of the engaged member 234 on the right side of the figure is cut with a nipper 236 or the like as shown in FIG. As a result, the engaged member 234 engaged with the engaging member 232 is separated from the upper lid 204, and the upper lid 204 can be removed from the lower lid 202. In the sealing structure 230 on the left side and the center, the engaging member 232 is provided with an engaging blocking portion 232e, so that the engaged member 234 is separated from the lower lid 202 together with the upper lid 204 as shown in FIG. Is done. In the sealing structure 230 on the right side of the drawing, the engaged member 234 remains on the lower lid 202 while being engaged with the engaging member 232.

  When sealing for the second time, first, as shown in FIG. 3C, the engagement blocking portion 232e is removed from the engagement member 232 at the center of the drawing. To remove the engagement obstruction part 232e, the two connection parts 232f may be cut by the nipper 236 or the like. Since the connection portion 232f is set to have a smaller cross-sectional area than the engagement blocking portion 232e, the connection portion 232f can be easily cut. By removing the engagement obstructing portion 232e, the contact surface 232g can come into contact with the contacted surface 234f of the engaged member 234. Then, as shown in FIG. 4D, when the lower lid 202 and the upper lid 204 are coupled again, this time, the engaging member 232 and the engaged member 234 are engaged in the sealing structure 230 in the center of the figure. . That is, the sealing is performed by the sealing structure 230 in the center of the figure. When the third sealing is performed after the second sealing is released, the engagement obstructing portion 232e of the engaging member 232 of the sealing structure 230 on the left side of the figure may be removed.

  In this embodiment, the cut surface after cutting the connection portion 232f is formed on a surface other than the contact surface 232g. Thereby, the contact surface 232g and the contacted surface 232f can always be properly contacted without being affected by the state of the cut surface.

  In the present embodiment, the engagement blocking portion 232e is formed on the engagement member 232, but the present invention is not limited to this. For example, the engagement disturbing part 232e may be formed on the engaged member 234, or the engagement disturbing part 232e may be formed on both the engaging member 232 and the engaged member 234.

  Further, in this embodiment, the engagement obstructing portion 232e is formed on the engagement member 232, and a position where the engagement surface 234f cannot contact the contact surface 232i by contacting a part of the member 234 to be engaged. However, the present invention is not limited to this, and the engagement obstruction part 232e is formed on the engagement member 232 and abuts against a part of the engaged member 234. Alternatively, 232i may be guided to a position where it cannot come into contact with the contacted surface 234f. Furthermore, the engagement obstructing portion 232e is formed on the engaged member 234, and abuts against a part of the engaging member 232 to guide the contact surface 232i to a position where it cannot contact the contacted surface 234f. Alternatively, it is formed on the engaged member 234 and abuts against a part of the engaging member 232 to guide the abutted surface 234f to a position where it cannot abut against the abutting surface 232i. May be.

  As described above, in the sealing structure 230 according to the present embodiment, the engaging member 232 includes the abutting surface 232i, and the engaged member 234 abuts the engaging member 232 and the abutting surface 232i. When the engagement member 234 is provided with a contact surface 234f that makes it impossible to release the engagement of the engaged member 234, and the engagement blocking portion 232e separates the engagement member 232 and the engaged member 234 from the engagement position, By abutting against a part of the engaging member 232 or the engaged member 234, at least one of the abutting surface 232i and the abutted surface 234f is guided to a position where they cannot be abutted with each other. Yes. For this reason, without adopting a complicated mechanism or structure, it is possible to reliably perform sealing with a simple and inexpensive configuration, and reliably prevent sealing when necessary.

  Further, in the sealing structure 230, when the sealing is not performed, it is not always necessary to elastically deform a part of the engaging member 232 or the engaged member 234. For this reason, even when the state where sealing is not performed continues for a long period of time, a part of the engaging member 232 or the engaged member 234 deteriorates and causes permanent deformation, and sealing becomes impossible or incomplete. Can be prevented. Thereby, the freedom degree of selection of the material which comprises the sealing structure 240 can be raised.

  When the engaging member 232 and the engaged member 234 are separated from each other, the engaging blocking portion 232e contacts the part of the engaged member 234 so that the abutted surface 234f becomes the abutting surface 232i. It is preferable that the engaging member 232 is formed so as to be guided to a position where the contact cannot be made.

  Further, when the engaging member 232e and the engaged member 234 are separated from each other, the engaging blocking portion 232e contacts the part of the engaging member 232 so that the contacted surface 234f is brought into contact with the contact surface 232i. It may be formed on the engaged member 234 so as to be guided to a position where it cannot contact.

  Further, the engagement obstruction part 232e may be constituted by another member that is not integrally formed with the engagement member 232.

Next, Embodiment 3 of the present invention will be described. The pachinko machine according to the present embodiment is obtained by applying a sealing structure 240 to the pachinko machine 100 according to the first embodiment, instead of the sealing structure 210, and other structures and processes are the same as those of the first embodiment. . For this reason, the same portions are denoted by the same reference numerals in the drawings, the description thereof is omitted, and only the sealing structure 240 will be described below.

In this state, the engaging member 242 and the engaged member 244 are in a state in which they can be engaged with each other, and are located at the engaging positions in the present invention.

  20A and 20B are views showing the structure of the engaging member 242. FIG. 20A is a view in the direction of arrow A in FIG. 4A, and FIG. 20B is a perspective view of FIG. The engaging member 242 includes a base end portion 242a that protrudes upward from the upper portion of the lower lid 202, and an insertion portion 242b that protrudes from the base end portion 242a toward the upper lid 204. The base end portion 242a is a plate-like member that is integrally connected to the lower lid 202. The insertion portion 242b is a plate-like member in which two substantially square-shaped openings 242c are formed. At the distal end of the insertion portion 242b, a substantially rectangular parallelepiped distal end portion 242d that projects the opening of the engaged member 244 protrudes.

  A substantially rectangular parallelepiped engagement blocking portion 242e is formed between the two openings 242c formed in the insertion portion 242b. The engagement obstruction part 242e is integrally connected to the insertion part 242b through two connection parts 242f formed on both the left and right sides. The two connection parts 242f are formed thinner (smaller in cross-sectional area) than the engagement blocking part 242e. A guide surface 242g formed in a slope shape is provided on the side surface of the engagement blocking portion 242e on the base end side of the insertion portion 242b. Further, the side edge of the opening 242c outside the two connection parts 242f is an abutment surface 242h. In the present embodiment, the engagement member 242 on the right side of the drawing is in a state where the engagement obstruction part 242e has been removed in advance.

FIG. 20C is a view in the direction of arrow B in FIG. 4A, FIG. 20D is a cross-sectional view taken along line NN in FIG. 19B, and FIG. It is a perspective view of 20 (d). The engaged member 244 includes two leg portions 244a provided on the upper portion of the upper lid 204, an outer wall portion 244b provided above the leg portion 244a, and a tongue piece 244c provided inside the outer wall portion 244b. Has been. The leg portion 244a is a short bar-like member that is integrally connected to the upper lid 204, and is a portion that is cut when the seal is released. The outer wall portion 244b is a box-like member having an opening on the lower lid 202 side, and this opening portion is an insertion hole 244d into which the engaging member 242 is inserted. The tongue piece 244c is a plate-like member protruding from the inner surface of the outer wall portion 244a opposite to the insertion hole 244d. A protruding portion 244e having a saw-toothed cross section protruding downward is formed at the distal end portion of the tongue piece 244c. The vertical surface of the protruding portion 244e on the base end side of the tongue piece 244c is the contact of the engaging member 242. A contacted surface 244f is in contact with the contact surface 242d. Further, a molding hole 244g necessary for molding the protruding portion 244e is formed in the outer wall portion 244b above the base end of the tongue piece 244c.

  21A is a cross-sectional view taken along line LL in FIG. 19B, and FIGS. 21B and 21C are cross-sectional views taken along line MM in FIG. 19B. FIG. 21A shows a case where the engaging member 242 from which the engagement obstructing portion 242e has been removed in advance and the engaged member 244 are respectively in the engaged position. In this case, the insertion portion 242b of the engaging member 242 is accommodated inside the outer wall portion 244b of the engaged member 244, and the distal end portion 242d at the distal end of the insertion portion 242b is accommodated in the molding hole 244g of the engaged member 244. It has become a state. The protruding portion 244e at the tip of the tongue piece 244c of the engaged member 244 is in a state of being fitted and engaged in the opening 242c formed in the insertion portion 242b of the engaging member 242. In this state, even if the engaged member 244 is moved away from the engagement position (upward in the drawing), the contact surface 242h of the engagement member 242 and the contacted surface 244f of the engaged member 244 are used. Therefore, it is impossible to move the engaged member 244 unless at least one of the engaging member 242 and the engaged member 244 is destroyed. That is, the substrate case 200 is sealed by the sealing structure 240.

  Further, when the engaging member 242 and the engaged member 244 are respectively in the engaged positions, they are shielded by the outer wall portion 244b of the engaged member 244, the base end portion 242a and the distal end portion 242d of the engaging member 242. Therefore, it is impossible to contact the insertion portion 242b or the tongue piece 244c from the outside.

  On the other hand, FIG. 21B shows a case where the engaging member 242 including the engaging blocking portion 242e and the engaged member 244 are in the engaged position. Also in this case, the insertion portion 242b of the engaging member 242 is accommodated inside the outer wall portion 244b of the engaged member 244, and the distal end portion 242d at the distal end of the inserting portion 242b is in the molding hole 244g of the engaged member 244. It is in a state of being accommodated in. And the protrusion part 244e at the front-end | tip of the tongue piece 244c of the to-be-engaged member 244 is the state fitted in the inside of the opening part 242c. From this state, when the engaged member 244 is moved in a direction away from the engagement position (upward in the drawing), the tip of the projecting portion 244e abuts on the guide surface 242g of the engagement blocking portion 242e, and the guide surface 242g Along the direction away from the abutted surface 244f (left side in the figure). In other words, the guide surface 242g cannot contact the contact surface 242h with the contact surface 242h while pressing the protruding portion 244e and elastically deforming the tongue piece 244c as the engaged member 244 moves. To the correct position.

  FIG. 21C shows a state after the contacted surface 244f is guided to a position where it cannot contact the contact surface 242h. When the engaged member 244 is further moved away from the engagement position from this state, the protruding portion 244e moves along the insertion portion 242b while the tongue piece 244c remains elastically deformed. The member 242 and the engaged member 244 can be separated. Since the opening 242c formed on the distal end side of the insertion portion 242b is set to be narrower than the width of the tongue piece 244c (see FIG. 20A), the protrusion 244e does not enter the opening 242c. There is no such thing. Thus, in this embodiment, when the engagement member 242 includes the engagement obstruction part 242e, the engagement member 242 and the engaged member 244 can be separated from the engagement position. The sealing by the sealing structure 240 is not performed.

  In the present embodiment, the substrate case 200 is provided with three sealing structures 240, and among them, the engagement member 242 of the two sealing structures 240 is provided with the engagement disturbing portion 242e, so that the re-sealing is performed twice. It is possible. FIGS. 22A to 22D are diagrams illustrating a procedure for performing reseal. In these figures, the sealing structure 240 on the right side of the figure is obtained by removing the engagement blocking part 242e in advance, and the sealing structure 240 on the left side and the center of the figure includes the engagement blocking part 242e. . Therefore, when the lower lid 202 and the upper lid 204 are first combined, sealing is performed by engaging the engaging member 242 and the engaged member 244 of the sealing structure 240 on the right side of the figure. When releasing the seal from this state, the leg 244a of the engaged member 244 on the right side of the figure is cut with a nipper 246 or the like, as shown in FIG. As a result, the engaged member 244 engaged with the engaging member 242 is separated from the upper lid 204, and the upper lid 204 can be removed from the lower lid 202. In the left and center sealing structures 240, since the engaging member 242 includes the engaging blocking portion 242e, the engaged member 244 is separated from the lower lid 202 together with the upper lid 204 as shown in FIG. Is done. In the sealing structure 240 on the right side of the figure, the engaged member 244 remains on the lower lid 202 while being engaged with the engaging member 242.

  When sealing for the second time, first, as shown in FIG. 5C, the engagement blocking portion 242e is removed from the engagement member 242 at the center of the drawing. To remove the engagement obstruction part 242e, the two connection parts 242f may be cut by the nipper 246 or the like. Since the connection portion 242f is set to have a smaller cross-sectional area than the engagement blocking portion 242e, the connection portion 242f can be easily cut. By removing the engagement obstructing portion 242e, the contact surface 242g can come into contact with the contacted surface 244f of the engaged member 244. Then, as shown in FIG. 4D, when the lower lid 202 and the upper lid 204 are coupled again, this time, the engaging member 242 and the engaged member 244 are engaged in the sealing structure 240 in the center of the figure. . That is, sealing is performed by the sealing structure 240 in the center of the figure. When the third sealing is performed after the second sealing is released, the engagement obstructing portion 242e of the engaging member 242 of the sealing structure 240 on the left side of the figure may be removed.

  In the present embodiment, the cut surface after cutting the connecting portion 242f is formed on a surface other than the contact surface 242h. Thereby, the contact surface 242h and the contacted surface 244f can always be properly contacted without being affected by the state of the cut surface. Further, since the connection portion 242f is formed so that the side surface of the connection portion 242f is continuous with the contact surface 242h, the side surface of the connection portion 242f remaining on the engaging member 242 after cutting is part of the contact surface 242h. It is configured. Thereby, since the area of the contact surface 242h is expanded, the engagement between the engaging member 242 and the engaged member 244 can be made more reliable.

  In the present embodiment, the engagement blocking portion 242e is formed on the engagement member 242, but the present invention is not limited to this. For example, the engagement disturbing part 242e may be formed on the engaged member 244, or the engagement disturbing part 242e may be formed on both the engaging member 242 and the engaged member 244.

  Further, in the present embodiment, the engagement obstruction part 242e is formed on the engagement member 242, and is in a position where it cannot contact the contact surface 242h by contacting a part of the member 244 to be engaged. However, the present invention is not limited to this, and the engagement blocking portion 242e is formed on the engagement member 242, and abuts against a part of the engaged member 244. 242h may be guided to a position where it cannot contact the contacted surface 244f. Furthermore, the engagement obstructing portion 242e is formed on the engaged member 244, and abuts against a part of the engaging member 242, and guides the contact surface 242h to a position where it cannot contact the contacted surface 244f. Alternatively, it is formed on the engaged member 244 and abuts against a part of the engaging member 242 to guide the abutted surface 244f to a position where it cannot abut against the abutting surface 242h. May be.

  As described above, in the sealing structure 240 according to the present embodiment, the engaging member 242 includes the abutting surface 242h, and the engaged member 244 comes into contact with the abutting surface 242h so that the engaging member 242 and When the engagement member 244 is provided with a contact surface 244f that makes it impossible to release the engagement of the engaged member 244, and the engagement blocking portion 242e separates the engagement member 242 and the engaged member 244 from the engagement position, By abutting against a part of the engaging member 242 or the engaged member 244, at least one of the abutting surface 242 h and the abutting surface 244 f is formed so as to be guided to a position where they cannot be abutted with each other. Yes. For this reason, without adopting a complicated mechanism or structure, it is possible to reliably perform sealing with a simple and inexpensive configuration, and reliably prevent sealing when necessary.

  Further, in the sealing structure 240, when the sealing is not performed, it is not necessary to always elastically deform a part of the engaging member 242 or the engaged member 244. For this reason, even if the state where sealing is not performed continues for a long period of time, a part of the engaging member 242 or the engaged member 244 deteriorates and causes permanent deformation, and sealing is impossible or incomplete. Can be prevented. Thereby, the freedom degree of selection of the material which comprises the sealing structure 240 can be raised.

  When the engaging member 242 and the engaged member 244 are separated from each other, the engaging blocking portion 242e contacts the part of the engaged member 244 so that the contacted surface 244f is brought into contact with the contact surface 242h. It is preferable that the engaging member 242 is formed so as to be guided to a position where it cannot be contacted.

  In addition, when the engaging member 242 and the engaged member 244 are separated from each other, the engaging obstructing portion 242e abuts a part of the engaging member 242, thereby causing the abutted surface 244f to contact the abutting surface 242h. It may be formed on the engaged member 244 so as to be guided to a position where the contact cannot be made.

Next, a fourth embodiment of the present invention will be described. The pachinko machine according to the present embodiment is obtained by applying a sealing structure 250 to the pachinko machine 100 according to the first embodiment, instead of the sealing structure 210, and other structures and processes are the same as those of the first embodiment. . For this reason, the same portions are denoted by the same reference numerals in the drawings, the description thereof is omitted, and only the sealing structure 250 will be described below.

At the distal end of the insertion portion 252b, a substantially rectangular parallelepiped distal end portion 252d that closes the opening of the engaged member 254 protrudes. A guide portion 252e having an inclined surface projects from the side edge of the opening portion 252c formed in the insertion portion 252b on the distal end side of the insertion portion 252b. The side edges of the opening 252c on both the left and right sides of the guide portion 252e are contact surfaces 252f.

  24C to 24E are views showing the structure of the engaged member 254. FIG. 24C is a view in the direction of arrow B in FIG. 4A, FIG. 24D is a cross-sectional view taken along line RR in FIG. 23B, and FIG. It is a perspective view of 24 (d). The engaged member 254 includes two leg portions 254a provided on the upper portion of the upper lid 204, an outer wall portion 254b provided above the leg portion 254a, and two tongue pieces 254c provided inside the outer wall portion 254b. It is composed of The leg portion 254a is a short bar-like member that is integrally connected to the upper lid 204, and is a portion that is cut when the seal is released. The outer wall portion 254b is a box-like member having an opening on the lower lid 202 side, and this opening portion is an insertion hole 254d into which the engaging member 252 is inserted. The two tongue pieces 254c are rod-shaped members that protrude from the inner surface of the outer wall portion 254a opposite to the insertion hole 254d. The distance between the two tongue pieces 254c is set to be slightly wider than the left and right widths of the guide portion 252e of the engaging member 252. A protruding portion 254e having a saw-tooth cross section protruding downward is formed at the distal end portion of the tongue piece 254c, and the vertical surface of the protruding portion 254e on the base end side of the tongue piece 254c is the contact of the engaging member 252. A contacted surface 254f is in contact with the contact surface 252d. Between the two protrusions 254e, there is provided a plate-like engagement obstructing portion 254g formed continuously with the two contact surfaces 254f so as to connect them. In addition, a molding hole 254h necessary for molding the protruding portion 254e and the engagement blocking portion 254g is formed in the outer wall portion 254b above the base end of the tongue piece 254c. In the present embodiment, the engaged member 254 on the left side of the drawing is in a state in which the engagement blocking portion 254g has been removed in advance.

  25A is a cross-sectional view taken along the line P-P in FIG. 23B, and FIGS. 25B and 25C are cross-sectional views taken along the line Q-Q in FIG. 23B. FIG. 25A shows a case where the engaged member 254 from which the engagement blocking portion 254g has been removed in advance and the engaging member 252 are in the engaged position. In this case, the insertion portion 252b of the engaging member 252 is accommodated in the outer wall portion 254b of the engaged member 254, and the distal end portion 252d at the distal end of the inserting portion 252b is accommodated in the molding hole 254h of the engaged member 254. It has become a state. The protruding portions 254e at the tips of the two tongue pieces 254c of the engaged member 254 are in a state of being fitted and engaged with the inside of the opening 252c of the engaging member 252, respectively. In this state, even if the engaged member 254 is moved away from the engagement position (upward in the drawing), the contact surface 252f of the engagement member 252 and the contacted surface 254f of the engaged member 254 are used. Therefore, it is impossible to move the engaged member 254 unless at least one of the engaging member 252 and the engaged member 254 is destroyed. That is, the substrate case 200 is sealed by the sealing structure 250.

  In this state, since the guiding portion 252e of the engaging member 252 is located between the two protruding portions 254e, the contacted surface 254f and the guiding portion 252e are in contact with each other even if the engaged member 254 is moved. It is supposed not to. Further, when the engaging member 252 and the engaged member 254 are respectively in the engaged position, they are shielded by the outer wall portion 254b of the engaged member 254, the proximal end portion 252a and the distal end portion 252d of the engaging member 252. Therefore, it is impossible to contact the insertion portion 252b or the tongue piece 254c from the outside.

  On the other hand, FIG. 25B shows a case where the engaged member 254 including the engagement blocking portion 254g and the engaging member 252 are in the engaged position. Also in this case, the insertion portion 252b of the engaging member 252 is accommodated inside the outer wall portion 254b of the engaged member 254, and the distal end portion 252d at the distal end of the inserting portion 252b is inside the molding hole 254h of the engaged member 254. It is in a state of being accommodated in. And the protrusion part 254e at the front-end | tip of the two tongue pieces 254c of the to-be-engaged member 254 is the state fitted in the inside of the opening part 252c. From this state, when the engaged member 254 is moved in a direction away from the engagement position (upward in the figure), the engagement obstruction part 254g abuts on the slope of the guide part 252g, and along the slope of the guide part 252g. It moves in the direction away from the contacted surface 254f (left side in the figure). As a result, the two projecting portions 254e also move in the direction away from the abutted surface 254f (to the left in the drawing) together with the engagement blocking portion 254g. In other words, the guiding portion 252g contacts the contact surface 252f with the contact surface 252f while pressing the engagement blocking portion 254g and elastically deforming the tongue piece 254c as the engaged member 254 moves. Guide to an impossible position.

  FIG. 25C shows a state after the contacted surface 254f is guided to a position where it cannot contact the contact surface 252f. When the engaged member 254 is further moved away from the engagement position from this state, the protrusion 254e moves along the insertion portion 252b while the tongue piece 254c remains elastically deformed. The member 252 and the engaged member 254 can be separated. Thus, in this embodiment, when the engagement member 252 includes the engagement obstruction part 254g, the engagement member 252 and the engaged member 254 can be separated from the engagement position. The sealing by the sealing structure 250 is not performed.

  In the present embodiment, the substrate case 200 is provided with three sealing structures 250, and the engagement member 252g of the two sealing structures 250 among them is provided with the engagement disturbing portion 254g, so that re-sealing is performed twice. It is possible. FIGS. 26A to 26E are diagrams showing a procedure for resealing. In these drawings, the right side sealing structure 250 in FIGS. 26 (a), (b) and (e) is obtained by removing the engagement blocking portion 254g in advance. The engagement obstruction part 254g is provided. In addition, since FIG.26 (c) and (d) are sectional drawings seen from the back side of FIG.26 (a), (b), and (e), the positional relationship on either side is reverse.

  When the lower lid 202 and the upper lid 204 are first combined, sealing is performed by engaging the engaging member 252 and the engaged member 254 of the sealing structure 250 on the right side of FIG. In order to release the seal from this state, the leg 254a of the engaged member 254 on the right side of the figure is cut with a nipper 256 or the like as shown in FIG. As a result, the engaged member 254 engaged with the engaging member 252 is separated from the upper lid 204, and the upper lid 204 can be removed from the lower lid 202. In the sealing structure 250 on the left side and the center in FIG. 10A, the engaged member 254 includes an engagement obstructing portion 254g. Therefore, as shown in FIG. 204 and separated from the lower lid 202. In the sealing structure 250 on the right side of FIG. 5B, the engaged member 254 remains on the lower lid 202 while being engaged with the engaging member 252.

  When sealing for the second time, first, as shown in FIGS. 3C and 3D, the engagement obstructing portion 254g is removed from the engaged member 254 at the center of the drawing by the nipper 256 or the like. By removing the engagement obstructing portion 254g, the contacted surface 254f can come into contact with the contacted surface 252f of the engaging member 252. Then, as shown in FIG. 5E, when the lower lid 202 and the upper lid 204 are coupled again, this time, the engaging member 252 and the engaged member 254 are engaged in the sealing structure 250 in the center of the figure. . That is, sealing is performed by the sealing structure 250 in the center of the figure. When the third sealing is performed after the second sealing is released, the engagement obstructing portion 254g of the engaged member 254 of the sealing structure 250 on the left side of the figure may be removed.

  In the present embodiment, the cut surface after cutting the engagement disturbing portion 254g is formed on a surface other than the contacted surface 254f. Thereby, the contact surface 252f and the contacted surface 254f can always be appropriately contacted without being affected by the state of the cut surface. Further, since the engagement obstruction portion 254g is formed so that the side surface of the engagement obstruction portion 254g is continuous from the abutted surface 254f, the side surface of the engagement obstruction portion 254g remaining on the engaged member 254 after cutting is reduced. A part of the abutted surface 254f is configured. Thereby, since the area of the abutted surface 254f increases, the engagement between the engaging member 252 and the engaged member 254 can be made more reliable.

  In the present embodiment, the engagement blocking portion 254g is formed on the engaged member 254 and the guide portion 252e is formed on the engaging member 252, but the present invention is not limited to this. For example, the engaging hindering part 254g may be formed on the engaging member 252, and the guiding part 252e may be formed on the engaged member 254. Alternatively, the engaging hindering part 254g and the guiding part 252e may be formed on the engaging member 252 and the covered member. You may make it form in both the engaging members 254. FIG.

  Further, in this embodiment, the guide portion 252e is formed on the engagement member 252, and abuts against the engagement obstruction portion 254g formed on the engaged member 254 so that the contacted surface 254f contacts the contact surface 252f. However, the present invention is not limited to this, and the guiding portion 252e is formed on the engaging member 252 and the engaging blocking portion formed on the engaged member 254. The contact surface 252f may be guided to a position where it cannot contact the contacted surface 254f by contacting with 254g. Further, the guide portion 252e is formed on the engaged member 254 and is in contact with the engagement obstructing portion 254g formed on the engaging member 252 so that the contact surface 252f cannot contact the contacted surface 254f. The contact surface 254f is in contact with the contact surface 252f by contacting the engagement obstruction portion 254g formed on the engagement member 254 and formed on the engagement member 252. It may be guided to an impossible position.

  As described above, in the sealing structure 250 according to the present embodiment, the engaging member 252 includes the abutting surface 252f, and the engaged member 254 abuts the engaging member 252 and the abutting surface 252f. A contact surface 254f that makes it impossible to release the engagement of the engaged member 254 is provided, and at least one of the engagement member 252 and the engaged member 254 is formed with an engagement obstructing portion 254g, When the engaging member 252 and the engaged member 254 are separated from the engaging position, the abutting surface of the engaging member 252 or the engaged member 254 is brought into contact with the engaging blocking portion 254g. A guiding portion 252e for guiding the 252f or the contacted surface 254f to a position where they cannot contact each other is formed. For this reason, without adopting a complicated mechanism or structure, it is possible to reliably perform sealing with a simple and inexpensive configuration, and reliably prevent sealing when necessary.

  Further, in the sealing structure 250, when the sealing is not performed, it is not necessary to always elastically deform a part of the engaging member 252 or the engaged member 254. For this reason, even when the state where sealing is not performed continues for a long period of time, a part of the engaging member 252 or the engaged member 254 deteriorates to cause permanent deformation, and sealing is impossible or incomplete. Can be prevented. Thereby, the freedom degree of selection of the material which comprises the sealing structure 250 can be raised.

  In the sealing structure 250, the engagement blocking portion 254g is formed on the engaged member 254, and the guide portion 252e is engaged when the engaging member 252 and the engaged member 254 are separated from the engagement position. It is preferable that the engaging member 252 is formed so as to guide the contacted surface 254f to a position where it cannot contact the contact surface 252f by contacting the blocking portion 254g.

  Further, in the sealing structure 250, the engagement blocking portion 254g is formed on the engagement member 252, and the guide portion 252e is engaged when the engagement member 252 and the engaged member 254 are separated from the engagement position. It may be formed in the engaged member 254 so as to guide the contact surface 252f to a position where it cannot contact the contacted surface 254f by contacting the part 254g.

  Although the embodiments of the present invention have been described above, the sealing structure according to the present invention is not limited to the above-described embodiments, and various modifications and changes can be made without departing from the scope of the present invention. It goes without saying that can be applied. For example, the sealing structures 210 to 240 described in the above embodiments include not only the substrate case 200 in which the main control board 192 is stored, but also the payout control board 196, the effect control board 190 constituting the effect control unit 350, and other boards.
