Description

  The present invention relates to a board storage case comprising a case main body and a case cover and capable of storing a control board provided in a gaming machine inside in a sealed state, and is particularly connected to a board-side connector mounted on the control board. The present invention relates to a board storage case provided with a connector restricting member that restricts removal and removal of a wiring side connector.

  Conventionally, a gaming machine such as a pachinko machine or a slot machine has been provided with a number of control boards such as a game control board for controlling games, and these control boards have electronic elements such as a CPU, a RAM, and a ROM. Many have been implemented. A program for controlling the game operation is stored in a ROM mounted on the game control board, and the game content can be easily changed by exchanging the ROM. And the case cover are provided in the gaming machine in a state of being housed in a board housing case. In particular, this board storage case can seal the case body and the case cover in a state in which the control board is stored so that a trace remains when the case cover is opened. Opening is prevented and fraudulent acts such as ROM replacement are suppressed.

  On the other hand, such a control board is provided with a board-side connector to which the harness-side connector is connected, and when the harness-side connector can be easily removed from such a board-side connector, There is a possibility that a harness to which a regular part is connected is pulled out and a harness to which an unauthorized part other than a regular part is connected. If the harness is exchanged in an unauthorized manner as described above, there is a problem in that it may not be possible to provide a fair game due to an illegal act such as changing the game play rate to an illegal value. .

A card unit lock is provided for releasing the card unit 50 in the case of doing so.

  Pachinko balls launched from the hitting ball launcher by the player's operation enter the game area 7 through the hitting rail, and then descend the game area 7. When a pachinko ball enters the first start port 15a and is detected by the first start port switch 14a, or enters the second start port 15b and is detected by the second start port switch 14b, a special symbol variation display is displayed. If it can be started, the special symbol on the special symbol display 8 starts to be displayed in a variable manner. If the special symbol variable display is not ready to start, the number of reserved memories is increased by one.

  The variation display of the special symbol on the special symbol display 8 stops when the variation display time set every time the variation display is performed. If the special symbol (stop symbol) at the time of stoppage is a jackpot symbol (also referred to as a jackpot display result) as a specific display result, it will be a jackpot and the game will shift to a jackpot gaming state. In the big hit gaming state, the special variable winning ball device 20 is released until a predetermined time elapses or a predetermined number (for example, ten) of pachinko balls wins. Then, if the pachinko ball wins the V winning area while the special variable winning ball apparatus 20 is opened and is detected by the count switch 23, a continuation right is generated and the special variable winning ball apparatus 20 is opened again. The generation of the continuation right is allowed with a predetermined number of times such as 15 rounds as an upper limit value. Such control is called repeated continuation control. In the repeated continuation control, a state in which the special variable winning ball apparatus 20 is opened is called a round. In addition, you may control not to provide V winning area but to generate a continuation right unconditionally in each round.

  When the special symbol on the special symbol display 8 at the time of stoppage is a predetermined special big hit symbol (probability big hit symbol) among the big hit symbols, the probability that it will be determined to be a big hit after the big hit gaming state (big hit probability) ) Becomes a more advantageous state for the player, a probability variation state (hereinafter referred to as a probability variation state) that becomes higher than the normal gaming state, which is a normal state different from the big hit gaming state. Hereinafter, the probability variation state is also referred to as a high probability state (sometimes abbreviated as a high probability state). Further, the non-probability change state is also referred to as a low probability state (sometimes abbreviated as a low probability state).

  In addition, when the display result of the special symbol when the variable display on the special symbol display 8 is stopped is the probability variation big hit symbol, the variable time is reduced after the big hit gaming state, and the control is performed for a predetermined period of time. The Compared to the normal gaming state, the time-short state is a variation display time of each of the special symbol display 8, the variation display device 9, and the normal symbol display 10 (the time from the start of variation to the time when the display result is derived and displayed). ) Is a control state in which display results are derived and displayed at an early stage. Furthermore, during the time-shortening state, the probability that the stop symbol in the normal symbol display 10 becomes a winning symbol is increased, the opening time of the movable pieces 13 and 13 of the start winning device 15 is lengthened, and the number of times of opening is increased. . In the short-time state, the display time of the fluctuation of the symbol is shortened, so that the number of reserved memories to be described later is exhausted early, and the start winnings that have occurred exceeding the upper limit (for example, “4”) of the number of reserved memories are invalidated. Since it is easy to derive and display the jackpot display result early in the short term, it is easy to derive and display the jackpot display result early, so the display result of the variable display is likely to become the display result of the jackpot symbol from a time efficient viewpoint It becomes a gaming state advantageous to the player. Thus, in the case of a probable big hit, the high probability state and the short time state are controlled in a predetermined period after the end of the big hit gaming state. The short time state over a predetermined period after the end of the jackpot gaming state is the earlier, either until the next jackpot gaming state occurs or until the special symbols and decorative symbols are displayed a predetermined number of times (100 times). Continue until either condition is met.

  Also, when considering the payout of pachinko balls according to the winning, the time-short state is shorter than the non-time-short state and the normal symbol variation display time is shortened, and the stop symbol in the normal symbol display 10 becomes a winning symbol. The probability is increased, the opening time of the movable pieces 13 and 13 of the start winning device 15 at the time of winning is lengthened, and the number of times of opening the movable pieces 13 and 13 of the starting winning device 15 at the time of hitting is increased. Based on this, the movable pieces 13 and 13 of the start winning device 15 are likely to be in an open state as compared with the normal gaming state. Accordingly, in the short-time state, it is easy to generate a prize (including both a case where the start prize is valid and a case where the prize is invalid) in the second start port 15b, so the number of pachinko balls ( The ratio of the number of pachinko balls (the number of balls to be paid out) to be paid out as winning balls according to the winning is greater than the number of hitting balls) as compared to the normal gaming state. In general, the ratio of the number of paid-out balls for winning a prize to the number of shot balls is called “base”. For example, when there are 40 payout balls with respect to 100 shot balls, the base is 40 (%). In the case of this embodiment, for example, a time-short state having a higher base than a non-time-short state such as a normal gaming state is called a high base state, and conversely, a normal gaming state having a lower base compared to such a high base state Such a non-short-time state is called a low base state.

  Thus, the ratio of the number of award balls paid out by winning a prize to the number of balls launched is generally called “base”, but the maximum number of pachinko balls fired per unit time such as 1 minute is limited to a certain number. ing. For this reason, the “base” can also be indicated by a total value of the number of winning balls paid out by winning a plurality of winning openings provided in the game area in a unit time. For example, assuming that the maximum number of pachinko balls fired per unit time is 100, the total number of award balls paid out by winning in a unit time matches the general “base” value. Based on such relevance, in the present embodiment, the first starting port 15a, the second starting port 15b, the first normal winning port 29, the second normal winning port 30, the third normal winning port 33, and the first Each of the four normal winning openings 39 is set as an abnormality monitoring target winning opening, and the total value of the number of paid-out balls by winning the abnormal monitoring target winning opening is called a base and is used as an abnormality monitoring target related to winning. .

  Whether the probability variation state (high probability state) or the non-probability variation state (low probability state) is determined based on whether or not the probability variation flag, which is a flag set in the probability variation state, is set. . Whether the time-short state (high base state) or the non-time-short state (low base state) is determined is based on whether or not the time-short flag, which is a flag set in the time-short state, is set. Is done.

  In addition, in the state that is not controlled in the above-mentioned time-short state, every time the number of special symbols on-hold storage exceeds a predetermined number, the memory that controls to the memory variation shortened state that shortens the variation display time of the special symbol and the decorative symbol Variation shortening control is performed. The memory fluctuation shortening control ends when the number of reserved symbols for special symbols is less than a predetermined number. Therefore, even in a state where the time-short state is not controlled, there is a case where the variation display time of the special symbol and the decorative symbol is shortened.

  In order to enhance the decorative effect of the special symbol variable display on the special symbol display 8, the decorative symbol that is variable displayed in the variable display device 9 is a variable decorative display that has a predetermined relationship with the special symbol variable display. It is a symbol with a special meaning. The predetermined relationship for such symbols includes, for example, the relationship in which the decorative symbol variation display starts when the special symbol variation display is started, and the special symbol display result at the end of the special symbol variation display. This includes a relationship in which the decorative symbol display result is derived and displayed and the decorative symbol variation display is terminated. When the special symbol display unit 8 derives and displays a predetermined jackpot symbol as a display result, the variable display device 9 derives and displays a combination of the jackpot symbol having left, middle and right symbols as a display result. The Such a display result of the jackpot symbol by the special symbol and the display result of the combination of the jackpot symbol by the decoration symbol are referred to as a jackpot display result.

  The special symbol display 8 and the fluctuation display device 9 have the correspondence relationship as described above, and therefore, in the following description, they may be collectively referred to as a fluctuation display unit.

  Next, the reach display mode (reach) will be described. The reach display mode (reach) in the present embodiment means that the symbols that have not been stopped when the stopped symbols constitute a part of the jackpot symbol, and all or This is a state where some symbols are synchronously displayed while constituting all or part of the jackpot symbol.

  For example, in the variable display device 9, an effective line (one effective line in the case of the present embodiment) that becomes a big hit when the symbol stops is determined in advance, and a part of the display area on the effective line is displayed. A state in which the variable display is performed in the display area on the active line that has not been stopped when the predetermined symbol is stopped (for example, the left, middle, and right variable display areas in the variable display device 9). Of these, all or some of the display area on the active line) Are in a variable display in synchronism while constituting all or part of the jackpot symbol (for example, the variable display is performed in all of the left, middle and right display areas in the variable display device 9, Same state) the variation displayed with the symbol are aligned is made that reach the display mode or reach.

  Also, during the reach, an unusual effect may be performed with LEDs or sounds. This production is called reach production. Further, in the case of reach, a character (an effect display imitating a person or the like, which is different from a design (decoration design or the like)) or a display mode (for example, a color or the like) of the background image of the variable display device 9 is displayed. ) May change. This change in character display and background display mode is called reach effect display. In addition, some reach is set so that when it appears, a big hit is likely to occur compared to a normal reach. Such special (specific) reach is called super reach.

  In addition, with respect to the variable display device 9, there is a case where a big hit notice is performed as a notice effect for notifying that a big hit will be given in the variable display that triggers the occurrence of the big hit.

  In the case of this embodiment, as a big hit, a plurality of types of big hits such as a normal big hit and a probable big hit are provided. In the following description, when “big hit” is simply indicated without specifying the types of big hits, it is a case where these multiple types of big hits are representatively shown.

  Normally, the big hit is a big hit (non-probable big hit) that becomes a low probability state and a low base state by not being in a probabilistic state after the end of the big hit gaming state and not being in a short time state. Such a state with a low probability state and a low base state is called a low probability low base state. The probabilistic big hit is a big hit that becomes a probable state after the end of the big hit gaming state, a high probability state in which the time is short for a predetermined period, and a high base state. Such a state with a high probability state and a high base state is referred to as a highly accurate high base state. After the probability variation big hit, when the predetermined period elapses, the time reduction state ends, and a high probability state and a low base state are obtained. Such a state having a high probability state and a low base state is referred to as a high probability low base state.

  In addition, with respect to the variable display device 9, there is a case where a big hit notice is performed as a notice effect for notifying that a big hit will be given in the variable display that triggers the occurrence of the big hit.

  The game control microcomputer 560 includes a ROM 54 for storing a game control (game progress control) program and the like, a RAM 55 as a storage means (variation data storage means for storing fluctuation data) used as a work memory, and a program. Therefore, it includes a CPU 56 that is a processor for performing a control operation, and an I / O port 506. The game control microcomputer 560 is a one-chip microcomputer. Note that the one-chip microcomputer may include at least the RAM 55 in addition to the CPU 56. Further, the ROM 54 and the I / O port 506 may be externally attached or built in.

  In the game control microcomputer 560, the CPU 56 executes control according to a program stored in the ROM 54. Therefore, what the game control microcomputer 560 described below executes (or performs processing) means that the CPU 56 executes control according to a program. The same applies to microcomputers mounted on boards other than the game control board 31. The game control means is realized by a game control microcomputer 560 including a CPU 56.

  The game control microcomputer 560 includes a clock circuit that generates a clock signal, a reset controller that functions as system reset means, a random number circuit, and a CTC that sends an interrupt request signal to the CPU 56.

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

  The game control microcomputer 560 reads numerical data from the random number circuit as the random number value R1 when a start winning to the first start port switch 14a or the second start port switch 14b occurs, and performs a specific operation based on the numerical data. It is determined whether or not to make a jackpot display result as a display result, that is, whether or not to make a jackpot. When it is determined that the game is a big hit, the gaming state is shifted to a big hit gaming state as a specific gaming state advantageous to the player. Whether the random number generated by the random number circuit is a big hit, such as a random number for probability variation determination for determining whether or not to make a probability variation, and a random number for variation pattern determination for determining a variation pattern of a special symbol. It may be used as a random number for determination other than determination.

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

  Further, the game control microcomputer 560 has a function of setting an initial value of numerical data updated by the random number circuit. For example, the game control microcomputer 560 stores the game control microcomputer 560 stored in a predetermined storage area such as the ROM 54. Numerical data obtained by performing a predetermined calculation using an ID number (an ID number assigned with a different numerical value for each product of the game control microcomputer 560) is used as an initial value of the numerical data updated by the random number circuit. Set. Thereby, the randomness of the random number generated by the random number circuit can be further improved. Further, when setting the initial value, by performing a predetermined calculation using the ID number, it is possible to make it difficult to recognize the initial value of the random number only by looking at the ID number of the game control microcomputer 560. Therefore, it is possible to more reliably prevent the transition condition to the big hit state from being illegally established by an action such as generating a capture signal using a radio signal to the pachinko gaming machine 1. Can be improved.

  The clock circuit outputs a system clock signal to the CPU 56, and outputs a reference clock signal CLK having a predetermined cycle generated by dividing the system clock signal to the power of 2 (= 128) to each random number circuit. When a low level signal is input for a certain period, the reset controller 502 outputs a predetermined initialization signal to the CPU 56 and each random number circuit to reset the game control microcomputer 560 as a system.

  In addition, the game control microcomputer 560 is equipped with two random number circuits having different ranges of random number values that can be generated. The first random number circuit is a random number circuit (hereinafter also referred to as a 12-bit random number circuit) that generates a 12-bit pseudo-random number. The 12-bit random number circuit has a function of generating a random number having a value in a range that can be generated by 12 bits (that is, a range from 1 to 4095). The second random number circuit is a random number circuit (hereinafter also referred to as a 16-bit random number circuit) that generates a 16-bit pseudo random number. The 16-bit random number circuit has a function of generating a random number having a value in a range that can be generated by 16 bits (that is, a range from 1 to 65535). One of the two random number circuits selected in advance is used to generate a random number.

  In this embodiment, the case where the game control microcomputer 560 includes two random number circuits will be described. However, the game control microcomputer 560 may include one random number circuit, and may include three or more random number circuits. A random number circuit may be incorporated. In this embodiment, when the 12-bit random number circuit and the 16-bit random number circuit are comprehensively expressed, or when any one of the 12-bit random number circuit and the 16-bit random number circuit is indicated, the random number circuit is referred to.

That is, even when the power supply to the pachinko gaming machine 1 is stopped, a part of the RAM 55 is kept for a predetermined period (until the backup power supply cannot be supplied because the capacitor as the backup power supply is discharged). Or the entire contents are preserved. In particular, at least data corresponding to the control state of the game (special symbol process flag or the like) and data indicating the number of unpaid prize balls are stored in the RAM 55 as backup data. The data corresponding to the control state is data necessary for restoring the control state before the occurrence of a power failure or the like based on the data when the power is restored after a power failure or the like. Further, data corresponding to the control state and data indicating the number of unpaid prize balls are defined as data indicating the progress state of the game. In this embodiment, it is assumed that the entire storage area of the RAM 55 is backed up.

  A reset signal from the power supply board 910 is input to the reset terminal of the game control microcomputer 560. The reset signal from the power supply board 910 is also input to the reset terminal of the payout control microcomputer. When the reset signal becomes high level, the game control microcomputer 560 and the payout control microcomputer become operable, and when the reset signal becomes low level, the game control microcomputer 560 and the payout control microcomputer stop operating. It becomes a state. Accordingly, during the period in which the reset signal is at a high level, an allowance signal that allows the operation of the game control microcomputer 560 and the payout control microcomputer is output, and during the period in which the reset signal is at a low level, An operation stop signal for stopping the operations of the game control microcomputer 560 and the payout control microcomputer is output. The reset circuit may be mounted on each electric component control board (including the game control board 31), or a reset circuit is mounted on one or more of the plurality of electric component control boards, and a reset signal is output therefrom. May be supplied to another electric component control board.

  Further, a power-off signal indicating that the power supply voltage from the power supply board 910 has dropped below a predetermined value is input to the input driver circuit 58 via the payout control board 37. The power-off signal is input to the input port of the game control microcomputer 560 via the input driver circuit 58. In addition, a clear signal indicating that a clear switch for instructing to clear the contents of the RAM is operated is input to the input driver circuit 58 at the input port of the game control microcomputer 560. The clear signal is input to the input port of the game control microcomputer 560 via the input driver circuit 58.

  Further, the game control microcomputer 560 has the above-described opening / closing plate of the special variable winning ball apparatus 20 when a ball is detected by the count switch 23 in a state other than the big hit gaming state, that is, for example, in a state other than the big hit gaming state. When an open state (first state) advantageous to the player by an unauthorized device or the like is detected and a ball is detected by the count switch 23, it is assumed that an error has occurred and the supply pan left LED 300a and the supply pan right LED 300b are caused to emit light. An error signal indicating this is transmitted to the effect control board 80.

  Further, the clear signal is branched in the game control board 31 and is also supplied to the payout control board 37. The state of the clear signal input by the game control microcomputer 560 via the input port may be output to the payout control board 37 via the output port.

  Each of the plurality of switches is connected to the input port of the game control microcomputer 560 via the input driver circuit 58. Thereby, the game control microcomputer 560 receives a setting detection signal indicating the setting state of each switch from each of the plurality of switches.

  Between the game control board 31 and the effect control board 80, there are provided eight signal lines for transmitting an effect control command and a signal line for an effect control INT signal for transmitting a strobe signal. .

  The game control microcomputer 560 transmits an effect control command (effect control signal) as a control signal for instructing effect control including display control, sound control, and LED control to the effect control board 80. The effect control board 80 receives an effect control command from the game control microcomputer 560 via the relay board 77 and performs an electric component control means such as an effect control microcomputer 81 for performing display control on the variable display device 9. Is installed.

  The effect control microcomputer 81 includes a ROM 84 that stores a display control program, a RAM 85 that is used as a work memory, a CPU 86 that is a processor that performs a display control operation according to the program, and an I / O port 87. Including. In response to the effect control command, the effect control microcomputer 81 performs control related to various display effects such as variable display of the variable display device 9, award ball LED 51, ball cut LED 52, decoration LED 25, top frame LED 28a, left frame. LED 28b, right frame LED 28c, supply tray left LED 300a, supply tray right LED 300b, supply tray front LED 301a, tray LED 302a control (LED control) and game sound generation control (sound control) using speaker 27 Take control.

  The effect control microcomputer 81 receives the effect control command at the capture timing indicated by the effect control INT signal. Then, in the effect control microcomputer 81, in order to perform display control, sound control, and LED control to be performed in response to the effect indicated by the received effect control command, the display control of the variable display device 9 and the speaker 27 are performed. Drive signals and various LED drive signals. In such a configuration, when effect control is performed based on the effect control command, sound control and LED control are performed by the effect control microcomputer 81 in accordance with the display control of the variable display device 9. That is, in the effect control microcomputer, the display control of the variation display device 9 is performed based on the effect control command, and the sound control and the LED control corresponding to the display control content are performed, whereby the display control of the variation display device 9 is performed. The sound control and LED control are performed in accordance with the production of (synchronized).

  On the effect control board 80, in addition to the effect control microcomputer 81, a VDP, a character ROM, and a VRAM (not shown) are mounted. The VDP is a processing device having a display control function for performing image display and a high-speed drawing function, and performs display control of the variable display device 9. The CPU 86 transmits control data for displaying an image according to the display control command to the VDP according to the received effect control command. Then, in order to display an image according to the control data transmitted as described above, the VDP reads necessary data from the character ROM. The character ROM is for storing image data to be displayed on the variable display device 9 in advance.

  The VDP has a two-dimensional address space independent of the CPU 86, and VRAM is mapped there. The VDP generates image data to be displayed on the variable display device 9 according to the image data of the character ROM, and the VDP expands the image data in the VRAM. VRAM is a frame buffer memory for expanding image data generated by VDP. The image data developed in the VRAM is output to the variable display device 9.

  The effect control microcomputer 81 outputs a sound such as a sound effect from the speaker 27 by outputting a drive signal of the speaker 27 to the sound output board 70. Further, the effect control microcomputer 81 controls the light emitting means as described above by outputting drive signals of various light emitting means to the LED driver board 35. Thereby, sound control and light emission control are performed in response to (in synchronization with) the effect display on the variable display device 9.

  In addition, when the production control microcomputer 81 receives a full signal from the game control board 31, it outputs a drive signal of the saucer LED 302 a to the LED driver board 35 to cause the saucer light emitting unit 302 to emit light, thereby causing a surplus ball. The player is informed that the pachinko ball is full in the saucer 4. The full tank notification is ended when the tray LED 302a is turned off when the full tank signal is not input.

  Further, when receiving the error signal from the game control board 31, the production control microcomputer 81 outputs drive signals for the supply dish left LED 300a and the supply dish right LED 300b to the LED driver board 35 to supply the supply dish left light emitting unit 300L. In addition, by causing the supply tray right light emitting unit 300R to emit light, the store staff of the game hall is notified that an error has occurred. The error notification is ended by turning off the supply tray left LED 300a and the supply tray right LED 300b based on the fact that the reset operation by the store clerk is performed.

  In addition, as a signal line for transmitting the effect control command, a configuration using one signal line, that is, a serial signal line is adopted instead of the configuration using the parallel signal lines such as the above-described eight. Also good. When the serial signal line is used, the production control command is serial data, the start bit of the low level signal is transmitted before the transmission of the serial data, and the stop bit of the high level signal is transmitted after the transmission of the serial data. Since the start control command capture timing is indicated by such a start bit and stop bit, the effect control microcomputer 81 receives serial data transmitted between the start bit and the stop bit as an effect control command. .

And the connecting portion 257 that connects the side wall 230, and the cylindrical portion 256 is disposed at a predetermined distance from the side wall 230 via the connecting portion 257. It can be cut with this tool. Further, a plurality of continuous portions 257 project outward from the outer surface of the side wall 230, which is one side edge of the case cover 202, and fixed portions 255a to 255d are provided at the tips of the respective continuous portions 257. It has been.

  The cylindrical portion 256 is a bottomed cylindrical body whose upper surface is open, and has a size that allows the one-way screw 280 to be accommodated therein. The bottom plate 258 has a diameter of the head 284 of the one-way screw 280. A mounting hole 259 having a smaller diameter is formed. The mounting hole 259 is arranged at a position facing each of the screw holes 211a to 211d in the sealed state.

  As shown in FIGS. 4 and 10, the side wall 231 corresponding to the side wall 204 in which the locked recess 215 on the case main body 201 side is formed has an upward facing direction that can be locked to the locked recess 215 at the tip. A locking piece 261 in which the locking strip 260 is extended in the longitudinal direction is extended outward.

  The case main body 201 and the case cover 202 configured as described above are formed on the inner surface of the side wall 205 of the case main body 201 and the low covering surface portion 220a of the case cover 202 in a state where the upper surface opening of the case main body 201 is closed by the case cover 202. A gap portion 505 through which a vertical plate 500b (described later) can be inserted is formed along the inner surface of the side wall 205 between the end surface of the long side 220d (see FIG. 8) that is the side facing the inner surface of the side wall 205. (See FIG. 12).

  Next, the structure of the connector restricting member 500 will be described. As shown in FIG. 9, the connector restricting member 500 is formed of a plate member made of a transparent synthetic resin material, and is configured to be attachable to the outside of the case cover 202. The width of the plate material is slightly shorter than the width of the long side 202d of the case cover 202 in the longitudinal direction. Specifically, the connector restricting member 500 includes an upper plate 500a formed slightly larger than the low covering surface 220a of the case cover 202 when mounted, and extends downward from the outer end of the upper plate 500a. And a lower plate 500c extending in the same direction so as to be parallel to the upper plate 500a from the lower end of the vertical plate 500b.

  The long side 500d of the upper plate 500a is configured to be able to be inserted into each of the plurality of engaging holes 502 described above and to be elastically deformable, and has a locking piece formed with an upward locking claw 501 at the tip. Is protruded so as to be substantially parallel to the upper plate 500a. When the locking piece is inserted into the case cover 202 from the engagement hole 502, the upper surface of the engagement hole 502 on the back surface of the case cover 202 is A locking claw 501 is locked to the edge.

  In the upper plate 500a, elongated rectangular wiring insertion openings 503a to 503c into which the wirings 291a to 291c extending from the wiring connectors 290a to 290c described above can be inserted are formed in the longitudinal direction. From each of the wiring insertion openings 503a to 503c, wiring insertion slits 504a to 504c through which the respective wirings 291a to 291c can be inserted are extended toward the long side 500d.

  Each of the wirings 291a to 291c is a so-called flat cable formed by bundling a plurality of cables in a line to form a band, and therefore, the wiring insertion openings 503a to 503c and the wiring insertion slits 504a to 504c. Is formed in a horizontally long rectangular shape. Specifically, the wiring insertion openings 503a to 503c are formed such that the long side and the short side are shorter than the long side and the short side of the main body of the wiring side connectors 290a to 290c, and the wiring side connectors 290a to 290c cannot be inserted. And the wirings 291a to 291c can be inserted. Further, the wiring insertion slits 504a to 504c are formed to have a width dimension that allows the wirings 291a to 291c to be inserted from the long side 500d side in a state of being parallel to the wiring insertion slits 504a to 504c.

  Therefore, each of the wirings 291a to 291c can be arranged in the wiring insertion openings 503a to 503c by being inserted into the wiring insertion slits 504a to 504c from the long side 500d side and drawn into the wiring insertion openings 503a to 503c. It can be done.

  The wiring insertion slits 504a to 504c are formed in parallel to each other so as to be inclined with respect to the opening long edge sides of the wiring insertion openings 503a to 503c, and in the longitudinal direction at the opening long edge sides. It extends obliquely from the center position toward the long side 500d. Accordingly, the wires 291a to 291c drawn through the wire insertion slits 504a to 504c can be obliquely advanced into the wire insertion openings 503a to 503c, so that the wiring insertion openings 503a to 503c can be smoothly inserted. Can enter.

  Further, the wiring insertion slits 504a to 504c are extended from the center position in the longitudinal direction of the long edge of the opening, so that the wiring 291a is disposed in the state where the wirings 291a to 291c are arranged in the wiring insertion openings 503a to 503c. Since both ends in the row direction of ˜291c are separated from the connecting portion with the wiring insertion slits 504a to 504c, the wirings 291a to 291c do not return back into the wiring insertion slits 504a to 504c. That is, the wiring insertion slits 504a to 504c are desirably narrower than one side of the wiring insertion openings 503a to 503c.

  The lower plate 500c extends from the lower end of the vertical plate 500b in the same direction as the upper plate 500a, and the extended width is slightly shorter than the width of the short side of the game control board 31. Yes. That is, the length is such that almost the entire back surface 31b (opposite surface of the mounting surface 31a) of the game control board 31 can be covered (see FIG. 12).

  As described above, the connector restricting member 500 formed in this way replaces the wirings 291a to 291c extending from the wiring side connectors 290a to 290c connected to the board side connectors 238a to 238c with the wiring insertion slits 504a. After passing through the wiring insertion openings 503a to 503c through ˜504c, they are brought close to the case cover 202 from the side, and the locking claws 501 are inserted into the engaging holes 502, and one end is engaged with the case cover 202. By stopping, the case cover 202 can be temporarily fixed.

  In this state, the upper plate 500a covers the upper and outer sides of the low covering surface portion 220a with the upper plate 500a and the vertical plate 500b, and the back surface 31b of the game control board 31 is covered with the lower plate 500c.

  Next, the game control board 31 is housed in a sealed state by the case body 201 and the case cover 202 configured as described above, and the wiring side connectors 290a to 290c are removed by the connector restricting member 500. Explain the regulatory situation.

  To store the game control board 31 in a sealed state, first, after attaching the cap suspension support body 245 to a cap holding portion (not shown) provided on the back surface of the case cover 202, the game control board 31 is placed in the case. It is attached to the back side of the cover 202. Specifically, as shown in FIG. 7, the back surface side of the case cover 202 with the mounting surface 31a of the game control board 31 facing the back surface of the case cover 202, that is, with the mounting surface 31a facing upward. Press against. Then, the positioning holes 243 formed at the two corners corresponding to the positioning convex portions 241 in the game control board 31 so that the board side connectors 238a to 238c are inserted through the connector openings 236a to 236c, respectively. In a state of being inserted into the positioning convex portion 241 and positioned, the board mounting screws 239 are attached to the screw mounting holes 242 formed at the two corners corresponding to the mounting posts 240 of the game control board 31, and the screw holes 240a A board mounting screw 239 is screwed into and attached.

  As shown in FIG. 8, when the game control board 31 is attached to the back side of the case cover 202, the upper parts of the board side connectors 238 a to 238 c are external to the case cover 202 from the connector openings 236 a to 236 c. To be exposed. That is, since the connection port 238d formed on the upper surface of the main body of each of the board side connectors 238a to 238c is opened upward to the outside of the case cover 202, the wiring side connectors 290a to 290c are not inserted into the case cover 202. The wiring side connectors 290a to 290c can be inserted and connected to the connection ports 238d of the board side connectors 238a to 238c.

  Next, as shown in FIG. 9, wirings 291a to 291c extending from the wiring side connectors 290a to 290c connected to the board side connectors 238a to 238c are connected to the wiring insertion slits 504a from the long side 500d side. ˜ 504 c, inserted through the wiring insertion openings 503 a to 503 c, then brought close to the case cover 202 from the side, and the locking claws 501 are inserted into the engagement holes 502, and one end thereof is attached to the case cover 202. By locking, the case cover 202 is temporarily fixed.

  In this manner, the wirings 291a to 291c can be easily inserted into the wiring insertion openings 503a to 503c in a state where the wiring side connectors 290a to 290c of the wirings 291a to 291c are connected to the board side connectors 238a to 238c. it can. In addition, it is not necessary to insert wiring side connectors (not shown) provided at the ends of the wirings 291a to 291c opposite to the wiring side connectors 290a to 290c into the wiring insertion openings 503a to 503c. Even when the ends of the wirings 291a to 291c opposite to the wiring side connectors 290a to 290c are directly connected to other substrates (not shown) without using a connector or the like, the wiring side connectors 290a to 290a Since it is not necessary to insert 290c into the wiring insertion openings 503a to 503c and it is not necessary to form a large opening in the upper plate 500a, the strength of the connector restricting member 500 is prevented from being reduced.

  On the other hand, as shown in FIG. 6, the case main body 201 stores the spare one-way screw 281 in the insertion hole 209 c of the screw storage portion 209. At this time, the threaded portion 283 can be easily accommodated simply by inserting the screw portion 283 into the insertion hole 209c (see FIG. 5B) from above the upper surface opening of each insertion hole 209c. In this storage state, the screw portion 283 is completely stored in the insertion hole 209c, and only the head portion 284 is held in a state of protruding outward from the upper surface opening of the insertion hole 209c (see FIG. 14A). ) When using the stored spare one-way screw 281, the head 284 can be simply taken out by hand.

  Next, the game control board 31 is integrally attached, and the upper surface opening of the case main body 201 is closed by the case cover 202 in which the connector restricting member 500 is temporarily fixed to the outside. Specifically, as shown in FIG. 10, the case cover 202 is tilted so that the locking piece 260 projecting outward from one short side of the case cover 202 faces downward. That is, with the back surface 31b of the game control board 31 facing the case body 201, the locking piece 260 is inserted between the upper end of the blocking wall 216 in the case body 201 and the lower end of the hanging piece 204b. Then, with the locking strip 260 locked in the locked recess 215, the case cover 202 is rotated around the locking portion in the direction of the arrow in the figure, and the case cover 202 is rotated to the case body. It fits in the space surrounded by the side walls 203-206 of 201.

  Here, the bulging portion covers 250a and 250b are fitted into the bulging spaces S2 and S3 of the bulging portions 208a and 208b of the case main body 201, and both the locking claws 251 are respectively positioned at the upper end edges of the locking holes 210. Locked. Accordingly, one short side of the case cover 202 is locked by the locking strip 260 and the locked recess 215, and the other short side is locked by the locking claw 251 and the locking hole 251. The case cover 202 is temporarily fixed to the case main body 201. In this state, the case cover 202 can be easily opened by releasing the locking state by pushing the respective locking claws 251 inward from the outside of the locking hole 210.

  In this state, the lower end of the screw restricting rib 253 extending downward from the upper wall rear surface 254 of the bulging portion cover 250a is the head of the three spare one-way screws 281 stored in the screw storage portion 209. Since the spare one-way screw 281 deviates from the screw storage part 209 and enters the board storage space S1, the wiring pattern of the game control board 31 is damaged and disconnected. Etc. are prevented.

  In addition, since the lower ends of the side walls 230 to 233 of the case cover 202 are deeper than the upper ends of the side walls 203 to 206 of the case main body 201, a wire or the like is inserted between the case main body 201 and the case cover 202. It becomes difficult to enter foreign objects.

  Further, since the screw storage portion 209 is provided in the bulging space S2 of the bulging portion 208a, the game control board 31 is disposed at a position below the upper end of the screw storage portion 209 in the board storage space S1. Even in the state (see FIG. 14B), there is no interference with the screw storage portion 209.

  12, the vertical plate of the connector regulating member 500 is formed in a gap 505 formed between the inner surface of the side wall 205 of the case body 201 and the long side 220d of the low covering surface portion 220a of the case cover 202. The lower plate 500c is placed on the upper surface of the bottom plate 201a of the case body 201 while being arranged with the 500b inserted. Thereby, the connector restricting member 500 is stably held with respect to the case main body 201, and the back surface 31b of the game control board 31 is covered with the lower plate 500c.

  That is, the connector restricting member 500 whose one end side is locked to the case cover 202 via the locking claw 501 has the lower plate 500c and the lower portion of the vertical plate 500b constituting a part of the connector regulating member 500 inside the case. Will be placed.

  Further, in this state, the first fixed portion 255 of the case cover 202 is disposed above the second fixed portion 212 of the case body 201. Specifically, when the fixed portions 255a to 255d are placed on the upper surface of the fixing piece 212a, the screw holes 211a to 211d and the attachment holes 259 are aligned with each other so that the one-way screw 280 can be inserted. Here, out of the four fixed portions 255a to 255d, any one of the cylindrical portions 256 (here, the fixed portion 255d corresponding to the use order number “1” displayed on the case cover 202 as described above). The one-way screw 280 is inserted from the upper surface opening of the cylindrical portion 256), and the one-way screw 280 is screwed clockwise with a tool such as a flat-blade screwdriver while the tip of the screw portion 283 is inserted into the mounting hole 259 (see FIG. 5). ).

  Accordingly, as shown in FIG. 13, the threaded portion of the external thread formed on the outer periphery of the threaded portion 283 causes the threaded portion 283 to penetrate the attachment hole 259 and penetrate into the fixing piece 212a and the tubular portion 212b. Then, the fixed piece 212a and the fixed portion 255d, that is, the second fixed portion 212 and the first fixed portion 255 are fixed (crimped) via the one-way screw 280.

  That is, the case cover 202 has one of the short sides fixed to the case main body 201 by locking the locking strip 260 by the locked recess 215 and fixing the other short side via the one-way screw 280. The game control board 31 is stored in a sealed state in the board storage case 200 with the mounting surface 31a and the back surface 31b covered by the case body 201 and the case cover 202. Is done.

  After the one-way screw 280 is completely screwed in, a colored adhesive Z colored in a predetermined color is injected into the cylindrical portion 256 from above, and then the cap 244 is placed in the upper surface opening of the cylindrical body 255d. The one-way screw 280 can be made difficult to remove by fitting and covering a groove or the like formed on the upper surface of the head 284.

  Further, when the colored adhesive Z is injected into the cylindrical portion 256 made of a transparent synthetic resin material, when there is some access to the one-way screw 280, the trace of the colored adhesive Z being scraped off. Since it becomes easy to visually recognize the color etc., it becomes easy to find a trace of fraud even from the outside of the transparent cylindrical portion 256.

  Further, when releasing the sealed state and opening the case cover 202, as described above, the one-way screw 280 cannot be removed by turning it counterclockwise. Or the connecting portion 257 is cut with a tool such as a nipper and the cylindrical portion 256 of the fixed portion 255a fixed to the fixing piece 212a via the one-way screw 280 is separated from the case cover 202. .

  That is, regardless of the method of destruction or cutting, if the case cover 202 is opened after the sealed state is released, traces of destruction or cutting will remain, so the case cover 202 may be damaged by, for example, fraud. Even if is opened, it is possible to discover that fraudulent acts have been performed early. As a result, even if it is replaced with a game control board or the like having a ROM in which an illegal game program is stored, it can be discovered and dealt with at an early stage. You can avoid incurring profits.

  Further, when the case cover 202 is fixed to the case main body 201 so as not to be opened by the one-way screw 280, the connector restricting member 500 temporarily fixed to the outside of the case cover 202 is attached to the case cover 202. The wiring side connectors 290a to 290c connected to the board side connectors 238a to 238c are restricted from coming into contact with the upper plate 500a.

  Specifically, as shown in FIG. 12, in the sealed state in which the case cover 202 is fixed to the case body 201 so as not to be opened, the connector restricting member 500 has the lower plate 500 c on the back surface of the game control board 31. By disposing the cover 31b below the cover 31b, the upward movement thereof is restricted by contact with the game control board 31 attached to the back side of the case cover 202 fixed to the case body 201. The

  In addition, the vertical plate 500 b continuously connected upward from the lower plate 500 c is sandwiched between the long side 220 d of the case cover 202 and the inner surface of the side wall 205 of the case main body 201, and the locking claw 501 is engaged with the engaging hole 502. By being stopped, the sliding movement of the case main body 201 on the bottom plate 201a is restricted, and deformation of the upper plate 500a is also prevented. In particular, since the outer surface of the vertical plate 500b is held in close contact with the inner surface of the side wall 205 in the vertical direction, deformation of the vertical plate 500b to the outside is also prevented. That is, the lower plate 500c, the vertical plate 500b, the long side 220d of the case cover 202, and the side wall 205 constitute the restricting member holding means of the present invention.

  As described above, the upper and horizontal movement of the connector restricting member 500 is restricted, so that the connector restricting member 500 is prevented from being detached from the case cover 202 and is stably held in the board storage case 200. Then, the upper surface 500a of the connector restricting member 500 held in the board storage case 200 in this way covers the upper surface of the low covering surface portion 220a of the case cover 202, the upper portion of the vertical plate 500b, the inclined covering surface portion 220c, Since the upper peripheral surface of the low covering surface portion 220a is covered by a part of the case cover 202, the board side connectors 238a to 238c and the wiring side connectors 290a to 290c are blocked from the outside. Fraud is prevented.

  Further, as shown in FIG. 12, an upper plate 500a is arranged near the upper side of the wiring side connectors 290a to 290c connected to the board side connectors 238a to 238c, so that the wiring side connectors 290a to 290c are connected to the board side connectors. When trying to pull out from 238a to 238c, the periphery of the extended portion of the wirings 291a to 291c on the upper surface of the main body of the wiring side connectors 290a to 290c is the periphery of the wiring insertion openings 503a to 503c on the back surface of the upper plate 500a. The contact regulating portion). That is, since the movement of the wiring side connectors 290a to 290c in the removal / removal direction is restricted by the upper plate 500a, it is possible to connect the wiring on which unauthorized parts other than the authorized ones are connected to the board side connectors 238a to 238c. It can be effectively prevented.

  Further, in the sealed state, the lower plate 500c is formed in a size that can cover the back surface 31b of the game control board 31, so that it is possible to suppress illegal acts on the wiring pattern and the like formed on the back surface 31b and Also improves. In this way, in this embodiment, the lower plate 500c is formed to have a size that can cover the back surface 31b of the game control board 31, but the upward movement of the connector restricting member 500 is controlled by the back surface of the game control board 31. As long as it has a length that can be regulated by contact with 31b, the entire back surface 31b may not be formed in a size that can be covered.

  Next, after the second fixed portion 212 and the first fixed portion 255 are fixed to each other via the one-way screw 280 to form a sealed state, the game control board 31 is fixed by a failure or inspection of the game control board 31. The case where the sealed state is released for removal and the sealed state is set again will be described.

  In addition, a plurality of screw holes 211a to 211d and fixed portions 255a to 255d are formed in this way so that they can be repeatedly sealed. For example, a manufacturer ships the game control board 31 to a game store or the like. In order to store the game control board 31 in the sealed state in the board storage case 200, the single screw holes 211a to 211d and the fixed portions 255a to 255d are used in the game store as described above. When the game control board 31 is failed and replaced, or when the game control board 31 is taken out for inspection or the like, the sealed state may be released. After that, when the sealing state is set again, the other screw holes 211a to 211d and the adherend portions 255a to 255d are used, so that a plurality of second adherend portions 212 and first adherent portions 255 are required.

  First, when the case cover 202 is opened, one cap 244 is separated from the cap suspension support 245 and taken out, and one spare one-way screw 281 is taken out from the screw storage portion 209. In the same manner as described above, the upper surface opening of the case body 201 is closed by the case cover 202. Here, a spare one-way screw 281 is attached to any cylindrical portion (for example, the fixed portion 255b corresponding to the use order number “2” described above) among the fixed portions 255b to 255d whose connection portions 257 are not yet cut. Is inserted and screwed into the screw hole 211b, the second fixed portion 212 and the first fixed portion 255 can be fixed and the sealed state can be configured in the same manner as described above.

  As described above, since the plurality of screw holes 211a to 211d as the second fixed portion 212 and the fixed portions 255a to 255d as the first fixed portion 255 are provided, a part of the case main body 201 or the case cover 202 is provided. Even after the sealed state is released, the sealed state can be repeatedly configured a plurality of times without cutting the connecting portion 257 without destroying the substrate, and without replacing the substrate storage case 200.

  As described above, in the board storage case 200 according to the first embodiment of the present invention, the board side connectors 238a to 238c are connected to the connector openings 236a to 236a by attaching the game control board 31 to the back surface of the case cover 202. The connector regulating member 500 is temporarily placed outside the case cover 202 with the wiring side connectors 290a to 290c connected to the opened board side connectors 238a to 238c. By being stopped and held in the substrate storage case 200, the removal of the wiring side connectors 290a to 290c is contact-controlled by the upper plate 500a as a contact control portion. In this way, the case cover 202 does not have to be formed with a large insertion port or the like for inserting the wiring side connector (not shown) opposite to the wiring side connectors 290a to 290c connected to the board side connectors 238a to 238c. In addition, since the connector restricting member 500 can be attached to the outside of the case cover 202, the strength of the connector restricting member 500 is prevented from being lowered.

  Further, the lower plate 500c is covered with the case body 201 and the case cover 202 which are in a sealed state, so that the connector restriction is performed unless the sealed state is released or a part of the connector restriction member 500 or the case 200 is destroyed. It becomes impossible to release the holding state of the member 500, so that when the wiring side connectors 290a to 290c are pulled out by destroying a part of the substrate storage case 200 or releasing the sealing state, the trace remains. , You will be able to reliably discover that fraud may have occurred.

  Further, in this embodiment, the lower plate 500c disposed inside the case in the sealed state functions as a restricting member holding means. Therefore, for example, the connector restricting member 500 is formed using a special holding member such as the one-way screw described above. Since the case cover 202 and the case main body 201 can be simply attached to the case cover 202 without being held by the case cover 202 or complicating the holding structure, the board side connectors 238a to 238c can be properly attached. It is possible to effectively prevent the connection of the wiring to which unauthorized parts other than the above are connected.

  Further, a part of the connector restricting member 500 is constituted by a single upper plate 500a capable of abutting and restricting the plurality of wiring side connectors 290a to 290c, and therefore, the plurality of wiring side connectors 290a to 290c. It is not necessary to individually form a plurality of contact restricting portions corresponding to each of them, and the plurality of wiring side connectors 290a to 290c can be collectively restricted, so that the labor of holding work is reduced.

  In addition to restricting the movement of the wiring-side connectors 290a to 290c in the removal / removal direction, the upper portions of the wiring-side connectors 290a to 290c are covered so that the connection portion between the board-side connectors 238a to 238c and the wiring-side connectors 290a to 290c In addition, it is not necessary to form a large insertion opening or the like for inserting the wiring side connectors 290a to 290c into the connector restricting member 500, so that a decrease in strength is prevented.

  Further, a part of the connector restricting member 500 includes a vertical plate 500b disposed in the gap portion 505 in a sealed state and a lower plate 500c whose movement in the disengagement direction is restricted by the game control board 31. Thus, the vertical plate 500b is inserted into the gap portion 505 without using a holding member such as a screw, and the sealing plate is brought into a sealed state. Since the movement of the plate 500b in the removal direction is restricted and held in the case, the mounting work of the connector restriction member 500 is facilitated.

  Since the connector restricting member 500 has a locking claw 501 that can be engaged with a locking hole 502 formed in the case cover 202, the locking claw 501 is engaged with the engaging hole 502. Since the upper plate 500a of the connector restricting member 500 is less likely to be deformed or damaged, the upper plate 500a is deformed to remove the wiring side connectors 290a to 290c from the gap formed between the case cover 202 and the like. It can be surely prevented.

  Further, the vicinity of the connector openings 236a to 236c on the mounting surface 31a of the game control board 31 is covered with the low covering surface 220a, thereby forming between the connector openings 236a to 236c and the board side connectors 238a to 238c. Since it becomes difficult to insert a fraudulent instrument etc. from a clearance gap, the fraudulent act with respect to the game control board 31 can be prevented.

  In addition, since the concave portion 234 is formed in the case cover 202 and the connector restricting member 500 is attached to the concave portion 234, the connector restricting member 500 does not protrude greatly from the case cover 202 in the attached state. In a state where the pachinko machine 1 is disposed, the connector restricting member 500 does not get in the way.

  In addition, since the connector restricting member 500 is made of a transparent synthetic resin material, the visibility in the board storage case 200 is not impaired by the connector restricting member 500, which hinders the monitoring of the game control board 31. I will not bring you.

  Further, among the plurality, at least a pair of screw holes 211a to 211d as first fixed portions and fixed portions 255a to 255d as second fixed portions are fixed to each other by a one-way screw 280 as a fixing member. The control substrate 31 can be in a sealed state, and the sealed state is released by destroying the substrate storage case 200 or cutting the connecting portions 257 of the screw holes 211a to 211d that are fixed to the case cover. 202 can be opened. Further, even after the sealed state is released by cutting the connecting portion or the like, the pair of unused screw holes 211a to 211d and the fixed portions 255a to 255d are fixed to each other by the spare one-way screw 281, so that the game is replayed. The control board 31 can be stored inside the case in a sealed state.

  Further, since the upper surface opening of the insertion hole 209c of the screw storage portion 209 is opened by opening the substrate storage case 200, the spare one-way screw 281 can be easily stored and taken out from the screw storage portion 209, and The spare one-way screw 281 stored in the screw storage unit 209 is prevented from deviating from the screw storage unit 209 in a sealed state of the game control board 31 by contact with the lower end of the screw control rib 253 as a control unit. Therefore, the game control board 31 can be prevented from being damaged by the deviated spare one-way screw 281.

  Further, the screw restricting rib 253 is extended downward from the upper wall rear surface 254 of the bulging portion cover 250a toward the upper surface opening of the insertion hole 209c of the screw accommodating portion 209, so that the screw accommodating portion 209 is arranged. Since the installation position is not limited by the shape of the case cover 202 or the case main body 201 or the shape of the case cover 202 or the case main body 201 does not need to be formed in accordance with the arrangement position of the screw storage portion 209, the substrate storage case It can avoid that the design of 200 becomes complicated.

  Specifically, for example, when the distance from the head 284 of the spare one-way screw 281 housed in the screw housing portion 209 to the back surface of the case cover 202 is larger than the length of the spare one-way screw 281, the spare one-way screw 281. There is a possibility that the screw 281 may deviate from the screw storage portion 209. Therefore, for example, if the location corresponding to the screw storage portion 209 in the case cover 202 is to be as close as possible to the upper surface opening of the insertion hole 209c of the screw storage portion 209, the shape of the entire case cover 202 or the arrangement of the screw storage portion 209 will be described. Although the design of the installation position must be changed, the design of the overall shape of the case cover 202 and the arrangement position of the screw storage portion 209 is not changed by extending the screw regulating rib 253 from a predetermined position on the back surface of the case cover 202. Just do it.

  Further, the strength of the bulging portion cover 250a is increased by extending the screw regulating rib 253 over the longitudinal direction of the upper wall back surface 254 so that deviation from the three spare one-way screws 281 can be regulated. Thereby, for example, when the case cover 202 is dropped and dropped on the floor or the like, the bulging portion cover 250a is not easily broken, so that the protective action of the first adherent portion 255 provided on the side thereof is achieved. Effectively increases.

  In addition, since the bulging portions 208a and 208b are provided on the front and rear sides of the second adherend portion 212 and the first adherent portion 255, the first and second adherent portions 255 and 208b can be compared with the case where the bulge portions 208a and 208b are provided only on one side. The two adherends 212 and the first adherent portions 255 are more effectively protected.

  Further, since the screw storage portion 209 provided in the bulging space S2 of the bulging portion 208a can accommodate a plurality of spare one-way screws 281 together, the screw holes 211a to 211d and the to-be-adhered portions Compared to storing the spare one-way screw 281 in the vicinity of each of 255a to 255d, not only can the structure of the case body 201 be simplified, but the spare one-way screw 281 can be easily managed.

  Further, the bulging portion 208a is formed in a part of the side wall 203 of the case body 201, and the second adherend portion 212 is provided on the side of the bulging portion 208a. In the case where the screw holes 211a to 211d and the fixed portions 255a to 255d are easily damaged, the screw holes 211a to 211d are prevented from being easily damaged, and the bulging space S2 formed inside the bulging portion 208a Since the spare one-way screw 281 can be stored in the provided screw storage portion 209, not only can the bulging portion 208a be used effectively, but also when the game control board 31 is stored or taken out. The spare one-way screw 281 can be stored so as not to get in the way.

  That is, the bulging portion 208a and the second adherend portion 212 are arranged linearly in the longitudinal direction of one side of the case body 201, and in particular, the screw holes 211a to 211d and the screw storage portion 209. Is arranged along one side, so that no irregularities are formed on the outer shape of the case body 201, so that not only the structure of the case body 201 can be simplified, but also the storage property during storage and transportation. improves.

  In addition, the screw storage portion 209 is connected to the game control board 31 in the bulging space S2 provided so as to protrude outward from the board storage space S1 inside the case body 201, that is, in a sealed state of the game control board 31. The game control board 31 is provided so as not to overlap in the vertical direction, and the game control board 31 is provided so as not to protrude into the bulging space S2, so that the spare one-way screw 281 can be stored and taken out. There is no interference with the game control board 31.

  Further, the spare one-way screw 281 includes a screw portion 283 that is an insertion portion that is inserted through the upper surface opening of the insertion hole 209 c of the screw storage portion 209, and a head portion 284 that is provided at one end of the screw portion 283. The screw storage portion 209 is configured to be held in a state where the head 284 protrudes outside the upper surface opening of the insertion hole 209c in a state where the spare one-way screw 281 is stored. The spare one-way screw 281 can be easily taken out from the screw storage portion 209.

  The game control board 31 includes a mounting surface 31a on which a plurality of electronic components and board-side connectors 238a to 238c are mounted, and a back surface 31b opposite to the mounting surface 31a. The case cover 202 includes connectors 238a to 238a. Connector openings 236a to 236c for opening the connection ports 238d of the connectors 238a to 238c to the outside of the case are formed at locations corresponding to the 238c, and the game control board 31 can be attached. 31 is opened in a sealed state inside the substrate storage case 200 with the mounting surface 31a covered with the case cover 202 and the back surface 31b facing the case body 201, so the substrate storage case 200 is opened. Even if the game control board 31 is attached with the mounting surface 31a covered with the case cover 202, And it has, it takes time to remove the game control board 31 from the case cover 202, made difficult to perform fraud for electronic parts and the board-side connector 238a~238c like.

  Next, a connector restricting member 520 as a second embodiment of the present invention will be described with reference to FIGS. 15 is a perspective view showing a connector restricting member and a case cover as a second embodiment of the present invention, and FIG. 16 is a plan view showing a board storage case to which the connector restricting member of FIG. 15 is attached. 17 is a sectional view taken along the line DD of FIG.

  In the first embodiment, the connector restricting member 500 is held in the substrate storage case 200 by the lower plate 500c disposed inside the case and the vertical plate 500b disposed in the gap portion 505 when the case main body 201 and the case cover 202 are sealed. However, the connector restricting member 520 according to the second embodiment is held by the case cover 202 by the fixing screw 522.

  Hereinafter, a difference between the connector restricting member 520 of the second embodiment and the connector restricting member 500 of the first embodiment will be described with reference to the drawings. In the second embodiment, the same components as those of the connector restricting member 500 of the first embodiment and the board storage case are denoted by the same reference numerals, and detailed description thereof will be omitted.

  The connector restricting member 520 is formed of a plate member made of a transparent synthetic resin material. As shown in FIG. 15, the upper plate 520a that can cover the upper side of the low covering surface portion 220a, and the upper plate 520a It is formed in a substantially L shape in a side view by a vertical plate 520b extending downward from the outer end. That is, the connector restricting member 500 according to the first embodiment is formed in a shape without the lower plate 500c, and the vertical width of the vertical plate 520b is shorter than the vertical width of the vertical plate 500b.

  In the upper plate 520a, wiring insertion openings 503a to 503c and wiring insertion slits 504a to 504c are formed. A plurality of (three in this embodiment) screw holes in which a plurality of attachment holes 521 to which the fixing screws 522 are attached are formed in the vertical plate 520b at predetermined intervals along the longitudinal direction of the end surface of the long side 202d of the case cover 202.

Detachment is regulated against contact.

  Further, in the state where the opening of the case main body 201 is closed (sealed state) by the case cover 202 to which the connector restricting member 520 is mounted in this way, as shown in FIGS. Since the head of the screwed fixing screw 522 is covered with the side wall 205 of the case main body 201, the fixing screw 522 is not released unless the sealed state of the case main body 201 and the case cover 202 is released or a part of the case is destroyed. It will be in the state which cannot be removed.

  Thus, even in the connector restricting member 520 of the second embodiment, the same operations and effects as the connector restricting member 500 of the first embodiment are exhibited. Further, since the connector restricting member 520 is directly fixed to the case cover 202 by the fixing screw 522 and is stably held with respect to the case cover 202, rattling or the like with respect to the case cover 202 hinders connector restriction. This is prevented.

  Further, since the head of the fixing screw 522 as the holding member is covered with the side wall 205 in the sealed state, the fixing screw 522 cannot be taken out from the mounting hole 523. Even without using a special member, it is possible to make it difficult to remove from the mounting hole 523.

  Further, as shown in FIG. 17, the end surface 520c of the upper plate 520a does not necessarily have to be in contact with and locked to the case cover 202, and may be close to the inclined covering surface portion 220c, for example. .

  In the connector restricting members 500 and 520 in the first and second embodiments, the vertical plates 500b and 520b are arranged in the gap portion 505 formed in the sealed state of the case main body 201 and the case cover 202. In the connector restricting member 550 of the third embodiment, the lower end of the vertical plate 550b is arranged on the upper surface of the low covering surface portion 220a.

  Hereinafter, a difference between the connector restricting member 550 of the third embodiment and the connector restricting member 500 of the first embodiment will be described with reference to the drawings. In the third embodiment, the same components as those of the connector restricting member 500 of the first embodiment and the board storage case are denoted by the same reference numerals, and detailed description thereof will be omitted.

  The connector restricting member 550 is formed of a plate member made of a transparent synthetic resin material. As shown in FIG. 18, the upper plate 550a that can cover the upper side of the low covering surface portion 220a, and the upper plate 550a A vertical plate 550b extending downward from the outer end is formed in a substantially L shape in side view. That is, it is formed in substantially the same shape as the connector restricting member 520 of the second embodiment, and the lower portion of the vertical plate 550b is formed slightly thick.

  In the upper plate 550a, wiring insertion openings 503a to 503c and wiring insertion slits 504a to 504c are formed. A plurality of screw holes 551 into which the fixing screws 552 are screwed are formed at predetermined intervals along the longitudinal direction of the groove 220e formed on the edge side of the low covering surface portion 202a of the case cover 202 at the lower end surface of the vertical plate 550b. Are formed at locations corresponding to a plurality (three in the present embodiment) of mounting holes 220f.

  The connector restricting member 550 thus formed has the wirings 291a to 291c inserted into the wiring insertion openings 503a to 503c as described above, and the fixing screws 552 are inserted into the mounting holes 220f from the back side of the case cover 202. In the attached state, the lower end surface of the vertical plate 550b is placed in contact with the upper surface of the recess 220e and placed outside the case cover 202, and the fixing screw 552 is screwed into the screw hole 551, thereby Attached and held.

  In this state, the connector restricting member 550 is held so as not to be detached from the case cover 202, so that the upper side of the wiring side connectors 290a to 290c is covered with the upper plate 550a, and from the board side connectors 238a to 238c. Detachment is regulated against contact.

  Further, when the opening of the case main body 201 is closed (sealed state) by the case cover 202 to which the connector restricting member 550 is mounted in this manner, as shown in FIG. 19, the screw holes 551 are screwed. Since the head of the fixing screw 552 is disposed inside the case and is covered with the case main body 201 and the case cover 202, unless the sealing state of the case main body 201 and the case cover 202 is released or a part of the case is destroyed. The fixing screw 552 cannot be removed.

  Thus, even in the connector restricting member 550 of the third embodiment, the same operations and effects as the connector restricting member 500 of the first embodiment are exhibited. Further, since the case cover 202 is directly fixed to the case cover 202 by the fixing screw 552 and is stably held with respect to the case cover 202, rattling or the like with respect to the case cover 202 is prevented from hindering connector regulation. .

  Further, since the head of the fixing screw 552 is covered with the case main body 201 and the case cover 202 in the sealed state, the fixing screw 552 cannot be taken out from the screw hole 551. Even if a special member such as the above is not used, it is possible to make it difficult to remove from the screw hole 551.

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

  For example, in the first to third embodiments, the board-side connectors 238a to 238c are mounted perpendicular to the mounting surface 31a of the game control board 31, that is, with the connection port 238c opened upward, and the connector opening 236a 236 c is formed on the upper plate 220 of the case cover 202, but the connector opening 236 c may be mounted with the connection port 238 c facing sideways, and the connector openings 236 a to 236 c may be formed on the side surface of the case cover 202. .

  In the first to third embodiments, the connector openings 236a to 236c are formed in the concave portion 234 formed in the case cover 202. However, the connector openings 236a to 236c may not necessarily be formed in the concave portion 234. .

  In addition, the connector restricting members 500, 520, and 550 of the first to third embodiments are configured to be able to abut and cover the plurality of wiring side connectors 290a to 290c. You may make it possible to attach to.

  In addition, the connector restricting members 500, 520, and 550 of the first to third embodiments are configured to come into contact with the upper surface of the main body of the wiring side connectors 290a to 290c to restrict removal, but the contacted portion is the upper surface of the main body. For example, if it is the main body of the connector, the side surface of the main body may be used.

  Further, in the substrate storage case 200 of the first embodiment, in the sealed state, the gap portion 505 is provided along the side wall 205 between the inner surface of the side wall 205 of the case body 201 and the long side 220d of the case cover 202. Although it is extended in a straight line, a part of the side wall 205 or a plurality of gaps 505 may be formed at predetermined intervals. Further, instead of the gap portions 505, an insertion hole or the like that allows an insertion piece portion that is a part of the connector restricting member 500 to be disposed inside the case may be formed in the case cover 202.

  Further, the connector restricting member 500 of the first embodiment is configured such that the upward movement is restricted by the lower plate 500c coming into contact with the back surface 31b of the game control board 31. A part of the lower plate 500c and the vertical plate 500b disposed in the case is brought into contact with a predetermined location other than the game control board 31 inside the case, for example, the inner surface of the side wall 205 of the case body 201 or the back surface of the case cover 202. The upward movement may be restricted.

  Moreover, in the said Example 2, 3, although the fixing screw was applied as a holding member for hold | maintaining the connector control member 520,550 to the case cover 202, it is not attached to the elastic piece etc. which were provided in the latch member or the connector control member. A locking claw may be formed and held on the case cover 202 by a locking action.

  In the first to third embodiments, the screw restricting rib 253 serving as a restricting portion that restricts contact of the deviation of the spare one-way screw 281 from the screw accommodating portion 209 is the screw accommodating portion in the case cover 202 in the sealed state. If it is possible to contact the deviation of the spare one-way screw 281 from the screw storage portion 209 in the sealed state, it is extended downward from the position directly above 209, that is, the surface facing the storage port. The connection position between the end of the screw regulating rib 253 and the inner surface of the case cover 202 is not limited to the surface facing the storage port, but from a location other than the facing surface, for example, from the side of the inner surface of the bulging portion cover 250a. It may extend in the horizontal direction.

  In the first to third embodiments, the screw restricting ribs 253 are formed in a plate shape extending in the longitudinal direction on the inner surface of the bulging portion cover 250a. However, the spare one-way screws 281 are individually brought into contact with each other. You may be comprised with the columnar member which can be controlled.

  In the first to third embodiments, the screw storage portion 209 is formed by the insertion hole 209c into which the screw portion 283 of the spare one-way screw 281 can be inserted, and the head 284 protrudes to the outside during storage. However, the entire spare one-way screw 281 may be accommodated.

  Moreover, in the said Examples 1-3, although the bulging part 208a was formed in planar view substantially rectangular shape, the shape can be changed variously, for example, it may be formed in semicircle shape etc.

  Moreover, in the said Examples 1-3, although the bulging part cover 250a was comprised so that it might fit in the surrounding wall inside of the bulging part 208a, you may make it fit in the outer side of a surrounding wall.

  Moreover, although the board | substrate storage case of the said Examples 1-3 was provided in the pachinko machine 1 which is an example of a game machine, it is applicable also to other game machines, such as a slot machine.

  In the first to third embodiments, the board storage case has been described as a case in which the game control board 31 can be stored. However, the control board stored in the case is not limited to the game control board. For example, it may be a case for storing the prize ball control board 37, the display control board 80, etc., and a connector restricting member can be applied to these cases.

  In the first to third embodiments, a structure for preventing the game storage board 31 from being replaced with an unauthorized control board by mainly opening the board storage case has been described. In order to prevent the control board and the board storage case from being removed from the gaming machine together with the board storage case included, for example, manufactured at a predetermined location on one or both of the case body 201 and the case cover 202 An IC tag or the like in which a number or a unique identification number (ID) is stored is provided, and a proper manufacturing number or a unique identification number (ID) or the like stored in the IC tag is appropriately determined by a predetermined reading device. By reading it out so that it can be confirmed at the game store or the like, the substrate storage case itself including the control substrate may be prevented from being illegally replaced.

  Further, in this case, such an IC tag is attached so as to straddle, for example, the case main body 201 and the case cover 202, and is a so-called sealing seal made of a brittle body that cannot be broken and resealed when the case cover is opened. It is preferable that it is provided integrally with the case body or attached to the case body or the case cover with the seal. In this way, since it can be determined by the reading device that the IC tag itself has been replaced with an illegal IC tag or has been lost, it can be dealt with early. Further, a manufacturing number, a unique identification number (ID), or the like may be printed on such a seal sticker so as to be visible.
