Description

  The present invention relates to a board storage case that includes a case main body and a case cover and can store a control board provided in a gaming machine in a sealed state.

  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 may be opened again after the case cover is opened because the case cover may be opened and the control board may be taken out in response to replacement or inspection due to a malfunction. A number of board storage cases that can be used have been proposed.

  As this type of substrate storage case, for example, a plurality of fixing portions for fixing the case body and the case cover are formed, and these fixing portions can be sealed by fixing them with fixing members such as one-way screws. In addition, after releasing the sealing state by, for example, cutting the fixing portion fixed by the fixing member from the case body or the case cover, the fixing portion different from the cut fixing portion is fixed and the sealing state is again set. Something that can be done has been proposed.

  Further, in these re-sealable substrate storage cases, a new fixing member is required for the second and subsequent fixings, and therefore, the preliminary fixing member used for resealing is not sealed in the case body. The spare fixing member stored in the storage unit in a sealed state is regulated by a part of the case cover so that it does not deviate from the storage unit. (For example, see Patent Documents 1 to 3).

  Examples of the present invention will be described below.

  A pachinko machine as an example of a gaming machine provided with a substrate storage case as Example 1 of the present invention will be described with reference to the drawings. First, FIG. 1 is a front view showing a pachinko machine to which the present invention is applied. 2 is a rear view showing the pachinko machine of FIG. 1, and the pachinko machine 1 is pivotally supported by a wooden base frame 1a (see FIG. 2) formed in a frame shape so as to be freely opened and closed. A glass door frame 2 formed in a frame shape is provided on the upper front surface. A hitting ball supply tray 3 is provided below the glass door frame 2. On the left and right sides of the hitting ball supply tray 3, sound emitting units 29 for sound effects output from the speakers 27 (see FIG. 3) provided therein are provided. Below the hit ball supply tray 3, there are provided an extra ball receiving tray 4 for storing pachinko balls overflowing from the hit ball supply tray 3 and a hit ball operating handle 5 for firing the hit ball.

  Behind the glass door frame 2, a game board 6, which is a model-specific part that is specific to the model of the gaming machine, is detachably attached. A game area 7 is provided in front of the game board 6. Further, behind the glass door frame 2, organic EL displays 100 a to 100 d which will be described in detail are provided in an area excluding the game area 7. Furthermore, game effect LEDs 28 are provided on the outer periphery of the game area 7 and the outer periphery of the display area 100. A full-color LED having light emitting elements of R (red), G (green), and B (blue), which are the three primary colors of light, is applied to the game effect LED 28. Red, green, blue, water, purple, yellow , 7 colors of white light can be emitted.

  The glass door frame 2 is located substantially in the center, and includes a glass plate as a see-through window through which the game area 7 can be visually recognized, and a glass frame that holds the glass plate. The glass frame is formed by molding a transparent resin such as polycarbonate. The glass frame covers the surface of the organic EL display devices 100a to 100d and displays the organic EL display devices 100a to 100d through the glass frame. The contents are visible. Thereby, the display area 100 (refer FIG. 1) in which the display content by the organic EL display devices 100a to 100d is displayed over almost the entire region of the glass door frame 2 excluding the glass plate, that is, the glass frame region.

  Near the center of the game area 7, a variable display device 8 including a variable display unit 9 and a variable display 10 is provided. The fluctuation display unit 9 is formed by an LCD display (liquid crystal display), and can display a plurality of types of identification information called “special symbols”, specifically numbers “1” to “9”. In addition, various production images can be displayed. Specifically, in the display area of the variable display unit 9, three variable display areas are formed on the display in a manner of being arranged in the horizontal direction (see FIG. 21A), and in these areas, the “left symbol”, “ Three special symbols “middle symbol” and “right symbol” can be individually and variably displayed. The variable display 10 can variably display a plurality of types of identification information called “ordinary symbols” in one symbol display area composed of 7-segment LEDs.

  The special symbol displayed on the variation display unit 9 starts to be varied based on the start winning of the hit ball to the start winning opening 14 as will be described later. On the other hand, the normal symbol displayed on the variable display 10 is variably started based on the hit ball passing through the passing gate 11 as described later.

  A start winning memory display 18 having four display portions (LEDs) for storing and displaying the number of starting winning balls won in the starting winning opening 14 is provided below the variable display portion 9. In this embodiment, with an upper limit of four, every time a start prize is stored, one LED of the start prize storage display 18 is lit. Each time the variable display of the special symbol is started in the variable display unit 9, one LED is turned off.

  A passing gate 11 for guiding a hit ball is provided on the side of the variable display device 8. The movable piece 15 is opened by a solenoid 16. The passing gate 11 includes a gate switch 12 (see FIG. 3) that detects a hit ball that has passed through the passing gate 11. Also, the hit ball that won the start winning opening 14 is detected by the start winning opening switch 17 (see FIG. 3).

  A variable winning ball device 19 provided with an opening / closing plate 20 is attached below the movable piece 15. When the gaming state becomes a big hit state (specific gaming state), the opening / closing plate 20 is opened by the solenoid 21 (see FIG. 3), and the big winning opening of the variable winning ball apparatus 19 is opened. Of the balls that have entered the big winning opening, the winning ball that has entered the specific winning area (V pocket) is detected by the V count switch 22 (see FIG. 3). On the other hand, a winning ball that has won a normal winning area other than the specific winning area in the special winning opening is detected by the count switch 23 (see FIG. 3).

  The game area 7 is provided with a plurality of winning holes 24a to 24d. The hit balls that have won the winning holes 24a to 24d are detected by the winning ball detection switches 99a to 99d (see FIG. 3). A decorative lamp 25 that is lit and displayed during the game is provided around the left and right sides of the game area 7, and an out port 26 that collects a hit ball that has not won a prize is provided at the bottom.

  A hit ball launched by a hammer that is swung by a drive motor 94 (see FIG. 3) by operating the hit ball operating handle 5 is detected by a launch ball detecting sensor (see FIG. 3), and then a hit ball rail (not shown). The game area 7 is entered through, and then the game area 7 flows down. At this time, the pachinko ball whose launch momentum is too weak to reach the game area 7 is recirculated to the surplus ball receiving tray 4 through a recirculation path (not shown). In addition, the hit ball collected in the out port 26 without reaching any winning port out of the hit balls that have reached the game area 7 is detected by the out ball detecting switch (see FIG. 3).

  Further, when a hit ball that has been driven into the game area 7 is detected by the gate switch 12 through the passing gate 11, the normal symbol that is stopped and displayed on the variable display 10 starts to change. If the hit ball passes through the passage gate 11 during the variable display of the variable indicator 10, the passage is stored, and the passage memory is stored after the variable indicator 10 is stopped and the fluctuation can be started again. By subtracting “1”, the variable display 10 is variably controlled. The upper limit of the passing memory is set to “4”, for example, and the current passing memory number is displayed by a passing memory display (not shown).

  Further, when the hit ball wins the start winning port 14 and is detected by the start winning port switch 17, the special symbol displayed on the variation display unit 9 starts scrolling if the variation of the special symbol can be started. For example, if the variation display is already started and the special symbol is changing, for example, if it is not in a state where the variation of the special symbol can be started immediately, the start winning memory is increased by one.

  When the display result after the variable display operation of the variable indicator 10 becomes a predetermined specific display result (for example, 7), the movable piece 15 provided in the start winning opening 14 is opened for a predetermined time, and the pachinko This is an advantageous state for the player who can easily win the ball at the start winning opening 14.

  When a pachinko ball is won at the start winning port 14 and is detected by the start winning port switch 17, if the special symbol can be changed, all the special symbols start to be displayed on the change display unit 9. After that, when the left, middle and right special symbols are stopped and the stop display result is a predetermined display mode (for example, 222 or 777), a specific gaming state (a big hit state) occurs. To do. A specific display mode in which such a big hit state occurs is called a big hit symbol, and in this example, a plurality of types are determined in advance. When the big hit state occurs in this way, the opening / closing plate 20 of the variable winning ball apparatus 19 is opened, which is a first state advantageous to the player. This first state ends when a predetermined period (for example, 30 seconds) or a predetermined number of hit balls (for example, 10) wins, whichever comes first, which is disadvantageous for the player thereafter. This is the second state. If a hit ball that has entered the large winning opening of the variable winning ball apparatus 19 in the first state enters the specific winning area (V pocket) and is detected by the V count switch 22, the first state of the time The opening / closing plate 20 is opened again after waiting for the end of the first state. In this embodiment, the repeated continuous control in the first state can be executed up to 15 times. Such a time when the first state that can be executed 15 times at maximum is called a round of repeated continuation control. In this example, the repeated continuation control can be repeatedly executed from the first round to the maximum 15th round.

  When the left, middle and right special symbols variably displayed on the variation display unit 9 are stopped and displayed with a combination of jackpot symbols matching the same symbol type, a big hit is generated as described above. Is a pre-determined type of jackpot symbol (a symbol of a special display mode) among a plurality of types of jackpot symbols, the jackpot is generated compared to the normal gaming state after the above-mentioned specific gaming state A probability variation state (hereinafter, also referred to as a probability variation state, in which the probability variation state is referred to as a true / slave mode in this embodiment) with a high probability of variation. A special display mode jackpot symbol (an odd symbol in this embodiment) that triggers the occurrence of such a probability variation state is called a probability variation symbol. Hereinafter, the jackpot generated by the probability variation symbol is referred to as a probability variation jackpot, and is distinguished from the regular jackpot that is a jackpot generated by a jackpot symbol other than the probability variation symbol (referred to as an ordinary symbol, which is an even symbol in this embodiment).

  Once the probability variation jackpot is generated in the normal gaming state, the probability variation state is continuously controlled to the probability variation state until, for example, at least a predetermined number of probability variation continuation times (for example, one time) has occurred. . In addition, if a probability variation jackpot is further generated during the probability variation state, the probability variation continuation count is counted again after that probability variation jackpot, and then the probability variation state continues until at least the probability variation continuation number is reached, that is, continuous It becomes a villa state. Then, if the big hit that has reached the probability variation continuation count is due to a normal symbol other than the probability variation symbol, after the big hit state ends, the fluctuation display unit 9 does not enter the probability fluctuation state, and the fluctuation display unit 9 Until the predetermined number of times (for example, 100 times) is reached, the movable piece 15 provided in the start winning opening 14 is changed to the first state that is advantageous to the player. The short-time state is referred to as 侍 mode).

  The improvement in the frequency at which the movable piece 15 which is the first state advantageous to the player in the short-time state is in the open state is substantially the same as the improvement in the opening frequency of the movable piece 15 during the probability variation. The time from variable display of 10 normal symbols to stop display is shorter than the normal gaming state (in this embodiment, the time from variable display to stop display is reduced from 30 seconds to 3 seconds in the normal gaming state). In addition, the period during which the movable piece 15 is opened is extended from the normal gaming state (0.5 seconds is extended to 3 seconds in the normal gaming state). The state where it is easy to make the start winning when the variable display is started is held, and the prize ball accompanying the starting winning is paid out, so that the player's possession ball does not greatly decrease during these short time states. To have.

  In this embodiment, the improvement in the frequency at which the movable piece 15 which is the first state advantageous to the player in the short time state is in the open state is the same as that in the probability variation state, but the present invention is not limited to this. It is not limited to these, The mode of these frequency improvement is good also as an individual mode in a time-short state and a probability fluctuation.

  In the fluctuation display of the fluctuation display unit 9, a reach state may occur. Here, the “reach state” means that the display mode of the jackpot is displayed even when the display of the change display unit 9 is started and the display control proceeds to the stage before the display result is derived and displayed. A display mode that does not deviate from the display condition. That is, reach refers to a display state that satisfies a condition in which a display result that has already been derived and displayed is a combination of specific display modes at a stage where some of the plurality of display results have not yet been derived and displayed. These reach states include a state in which variable display is performed while maintaining a state where a combination of specific symbols in a specific display mode is maintained, specifically, a full rotation state in which the same specific symbols are rotated together, etc. Included in the display state. Further, in the reach state, when it appears, there are those that are more likely to generate a big hit than normal reach (normal reach), for example, reach due to the above-mentioned full rotation state. Such reach is called super reach. In addition, some reach has a fairly low probability, but when it appears, it will almost certainly cause a big hit. Such reach is called premium reach.

In this state, the case cover 202 can be easily opened by releasing the locking state by pushing each locking claw 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 provided with 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 portion 209 and enters the board storage space S1, the wiring pattern of the game control board 31 is damaged and disconnected. Is 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. 10), there is no interference with the screw storage portion 209.

  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 255a corresponding to the use order number “1” displayed on the case cover 202 as described above). The one-way screw 280 is inserted through the top 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.

  As a result, the threaded portion of the external thread formed on the outer periphery of the threaded portion 283 causes the threaded portion 283 to pass through the attachment hole 259, and to be threaded into the threaded hole 211a formed through the fixed piece 212a and the tubular portion 212b. The fixed piece 212a and the fixed portion 255a, 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. Since the case cover 202 is fixed so as not to be opened, the game control board 31 is sealed in the board storage case 200 with the mounting surface 31a and the back surface 31b covered with the case body 201 and the case cover 202. Stored in a state.

  After the one-way screw 280 is completely screwed in, a cap 244 having an adhesive or the like applied to the peripheral edge is fitted into the upper surface opening of the cylindrical body 255a from above (see FIG. 5B), and the head The one-way screw 280 can be made difficult to remove by covering the groove formed on the upper surface of 284.

  When releasing the sealed state and opening the case cover 202, the case body 201 or part of the case cover 202 is destroyed because the one-way screw 280 cannot be removed counterclockwise as described above. Alternatively, 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.

  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 substrate storage case 200 according to the first embodiment of the present invention, at least a pair of screw holes 211a to 211d as the first fixed portions and the covered portions as the second fixed portions among the plurality. By fixing the fixing portions 255a to 255d with a one-way screw 280 as a fixing member, the game control board 31 can be brought into a sealed state, and the board storage case 200 is destroyed or fixed screw holes 211a. By cutting the connecting portion 257 of ˜211d, the sealed state can be released and 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.

Yes. In addition, since a flange piece 231a (see FIG. 20A) extends in the longitudinal direction above the slit 360, the insertion pieces 352 and 352 can be easily cut from above the case cover 202. The case cover 202 cannot be opened.

  Next, a situation where the upper surface opening of the case body 201 is closed by the case cover 202 will be described with reference to FIGS. 19 and 20.

  First, in the same manner as the board storage case 200 of the first embodiment, the game control board 31 is attached to the back side of the case cover 202 and the spare one-way screw 281 is stored in the screw storage section 209. On the other hand, the case cover 202 is lowered toward the case main body 201 in a posture in which the back surface 31b of the game control board 31 is opposed to each other and the guide pieces 355 are arranged directly above the openings of the respective guide grooves 300. At this time, each guide piece 355 is not visible from above the case cover 202, but the guide piece 355 can be arranged immediately above the opening of the guide groove 300 using the molding opening 356 arranged just above it as a guide. .

  20A, in the state where the guide piece 355 is loosely inserted into the vertical groove 350b from the opening of the guide groove 300, the case cover 202 is attached to the case main body 201. It is arranged at a position slightly shifted in the longitudinal direction. In this state, the guide cover portion 354 is fitted to the upper ends of the side walls 205 and 206.

  From this state, the case cover 202 is pushed horizontally toward the side wall 230 (see FIG. 19). At this time, the case cover 202 is prevented from shaking in the left-right direction with respect to the moving direction by the guide cover portion 354 fitted to the upper ends of the side walls 205 and 206. 20A, the insertion piece 352 is inserted into the slit 360 formed in the side wall 231 of the case cover 202, and the end surface of the horizontal piece 353 comes into contact with the inner surface of the side wall 231. In addition, as shown in FIG. 20B, the tip of the flange piece 357 a of the bulging portion cover 357 abuts on the inner surface of the bulging wall 203 b of the case main body 201, so that the case cover 202 against the case main body 201 is obtained. And the case cover 202 is positioned at the closed position.

  Since the guide piece 355 enters the straight groove 350a from the vertical groove 350b as the case cover 202 slides (see FIG. 20A), the guide piece 355 is moved upward by the side wall 206 above the straight groove 350a in the closed position. Movement to the side, that is, lifting is reliably prevented.

  Further, since the collar piece 357a is disposed close to the head 284 of the spare one-way screw 281 stored in the screw storage portion 209 provided in the expansion space S2 of the expansion portion 208a, the screw storage portion Deviation of the spare one-way screw 281 from 209 is prevented.

  Thereafter, a one-way screw 280 is inserted from the upper surface opening of any one of the four fixed portions 255a to 255d (here, the fixed portion 255a) (see FIG. 16B), and the screw portion 283 With the tip inserted into the mounting hole 259, the one-way screw 280 is screwed clockwise with a tool such as a flat-blade screwdriver, and the second fixed portion 212 and the first fixed portion 255 are fixed (caulking) with the one-way screw 280. )

  As described above, in the substrate storage case 200 ″ of the third embodiment, the case cover 202 can be easily opened and closed by sliding the case cover 202 in the horizontal direction with respect to the case main body 201. . In addition, since the other components are the same as those of the substrate storage case 200 of the first embodiment, the same operations and effects as the first embodiment are achieved.

  Next, the wiring pattern of the game control board 31 applied in the first to third embodiments will be described with reference to FIG. FIG. 21A is a diagram showing the main part of the mounting surface 31a of the game control board, and FIG. 21B is a diagram showing the main part of the back surface 31b of the game control board.

  Various connectors 238 are arranged on the mounting surface 31a of the game control board 31 as shown in FIG. Specifically, while facing the connection port 238a upward, a plurality of terminals (not shown) protruding from the back surface of the connector 238 are mounted on the mounting surface 31a side in the terminal insertion hole 400 formed through the game control board 31. The terminal protruding from the back surface 31b through the terminal insertion hole 400 is welded and fixed by solder.

  Wiring patterns connected to the terminals of the connectors 238 around the various connectors 238 on the mounting surface 31a (specifically, regions corresponding to the connector openings 235, 236, and 237 formed in the case cover 202) 401 is not formed, and these wiring patterns 401 are extended from each terminal insertion hole 400 in the back surface 31b (see FIG. 21B).

  Here, for example, a wiring or the like extended from an unauthorized electronic component is inserted through a slight gap formed between the main body side surface of each connector 238 and the opening edge of the connector opening 235, 236, 237. There is a risk that an illegal signal or the like is connected to the wiring pattern 401 and is output to the game control microcomputer. By forming the wiring pattern 401 on the back surface 31b in this way, connector openings 235, 236 and 237 are formed. In other words, compared to the case where the wiring pattern 401 is formed on the mounting surface 31 a that is the surface facing the case cover 202, the possibility that wiring from an unauthorized electronic component is connected to the wiring pattern 401 is reduced. Therefore, an illegal act such as inputting an illegal signal or the like into the game control microcomputer can be effectively suppressed.

  Further, the board storage cases 200, 200 ′, and 200 ″ that store the game control board 31 in a sealed state, as shown in FIG. 2, the back surface of the pachinko machine 1 with the case cover 202 facing outward. Attached to the side. That is, since the game control board 31 is attached with the mounting surface 31a facing outward, the gaming control board 31 is more likely to perform an illegal act on the back surface 31b than when an illegal act is performed on the mounting surface 31a. Since cheating becomes more difficult, cheating can be suppressed.
