In the pachislot machine 1, each means shown in FIG. 1 executes a necessary process, and a function performed by each means is exhibited, thereby enabling a player to execute a game.

<Input operation detection means>
The input operation detecting means detects an input operation of a game medium such as a medal or a coin by the player. When an operation for inserting a predetermined number of game media (for example, three medals) is detected, detection of the start operation by the start operation detecting means described later is permitted. In addition, a predetermined pay line is activated in a symbol display means to be described later (hereinafter, the activated pay line is referred to as an “effective line”). In the present embodiment, the selector 66 that detects insertion of medals by the player constitutes insertion operation detection means. Note that the types of game media that can be detected are not limited to medals, but include coins, tokens, game balls, or electromagnetic game media having a value equivalent to these.

<Starting operation detection means>
The start operation detecting means detects a start operation by the player. When a start operation is detected, symbol variation display by symbol display means described later is started. In addition, a random number value used when an internal winning combination determining means to be described later determines an internal winning combination is extracted from a predetermined numerical range (for example, 0 to 65535). In addition, an effect random number value used when the effect control means (to be described later) determines the effect is extracted from a predetermined numerical range (for example, 0 to 32767). In the present embodiment, the start switch 79 that detects the operation of the start lever 23 by the player constitutes a start operation detecting means. Note that the type, number, and numerical range of random numbers to be extracted are not limited to this, and the number of random values that are required in the game can be extracted from a predetermined numerical range. .

<Internal winning combination determination means>
The internal winning combination determining means performs lottery based on the extracted random number value and determines an internal winning combination from a plurality of predetermined combinations. That is, the combination of symbols allowed to be displayed on the active line is determined by determining the internal winning combination. In the present embodiment, the main control circuit 91 that refers to various tables and executes the internal lottery process based on the extracted random number value constitutes an internal winning combination determining means. The types of symbol combinations include those related to “winning” in which benefits such as medal payout, replay operation, bonus operation, etc. are given to the player, and other so-called “losing” Such a thing is provided.

  In addition, the pachislot machine can perform control to stop the progress of the game. Such control is referred to as “lock” (or “freeze”). For convenience, the control that stops the progress of the game that is executed at the start of the game is called “game start lock”, and the control that stops the progress of the game that is executed at the end of the game is called “game end lock”. Call. In other words, the “game start lock” is a control in which the progress of the game is stopped in the sense that the operation to the stop button is not effective for a predetermined period after the start lever is operated, “Lock at the end of the game” means that the operation of the game is stopped in the sense that the operation to the bet button or the operation to the start lever is not effective for a predetermined period after the stop button is operated. Control. Of course, the trigger of “lock” is not limited to the above. For example, after the start lever is operated and any one of the stop buttons is operated, the subsequent operation is valid for a predetermined period. It is good also as performing the control which does not become.

  Here, the internal winning combination determination means can determine whether or not to perform “locking” by lottery based on the extracted random number value, instead of the internal winning combination or together with the internal winning combination. In this case, a plurality of random number values are extracted, an internal winning combination is determined based on one of the random number values, and whether to perform “lock” based on the other random number value is determined. It is good.

<Design display means>
The symbol display means variably displays a plurality of symbols in a plurality of columns. That is, when the start operation is detected by the start operation detecting means, the symbol fluctuation display is started, and when the stop control is executed by the stop control means described later, the symbol fluctuation display is ended. In the present embodiment, the plurality of reels 3L, 3C, 3R and the reel display window 4 constitute a symbol display means.

  The first stop operation that is performed first when all the reels are rotating is the first stop operation, the stop operation that is performed after the first stop operation is the second stop operation, and the second stop operation is performed next. The stop operation that is performed is referred to as a third stop operation.

<Stop control means>
The stop control unit controls the stop of the symbol variation display in the symbol display unit. That is, when the stop operation is detected by the stop operation detecting means, the symbol display on the symbol display means is stopped based on the stop control information set according to the internal winning combination determined by the internal winning combination determining means. Control. In this embodiment, when the stop button 19L, 19C, 19R is operated by the player, a reel stop control process for stopping and controlling the rotation of the corresponding reels 3L, 3C, 3R is executed with reference to various stop control information. The main control circuit 91 that constitutes the stop control means.

  Here, in the pachi-slot machine, basically, control for stopping the rotation of the corresponding reel is performed within a specified time (190 msec or 75 msec) from when the stop button is pressed. In the present embodiment, the number of symbols that move with the rotation of the reel within the specified time is referred to as “the number of sliding symbols”. When the specified period is 190 msec, the maximum number of sliding symbols is set to 4 symbols, and when the specified period is 75 msec, the maximum number of sliding symbols is set to 1 symbol. The maximum number of sliding pieces is not limited to these and can be set as appropriate.

  The stop control means uses the specified time for the combination of symbols permitted to be displayed according to the determination result of the internal winning combination so that the symbol combination is displayed as much as possible along the active line. The rotation of the reel is stopped within the range of the maximum number of sliding pieces.

In the present embodiment, the main control circuit 91 that executes a medal payout process based on the result of the winning search process constitutes a profit granting unit. In the case where the benefit to be given is given by the control of the sub-control circuit 101, the sub-control circuit 101 constitutes a profit grant unit.

  Here, the profit granted by the profit granting means includes the medal payout, the re-game operation that allows the same amount of game media as the current game to be automatically inserted, and the game can be played again. Re-play high probability state (replay time) that increases the winning probability of winning combination, special gaming state (bonus) that increases the internal winning combination probability related to the payout of medals, stop operation appropriate to the player By notifying this information, the operation of a specific gaming state (assist time) in which the winning probability of the internal winning combination related to the payout of medals becomes high can be cited. In addition, the profit which a profit provision means gives is not restricted to this.

  Thus, in the pachislot machine, when the player's throwing operation is detected by the throwing operation detecting means and the player's starting operation is detected by the starting operation detecting means, the internal winning combination is determined by the internal winning combination determining means. At the same time, the symbol display by the symbol display means is started. Then, when the stop operation of the player is detected by the stop operation detecting means, the stop control means controls the change display of the symbols by the symbol display means, and the combination of symbols displayed on the symbol display means is the winning determination means When it is determined that the symbol combination is related to winning, a profit corresponding to the symbol combination is given by the profit granting means. A series of flows as described above is performed as one game (unit game) in the pachislot machine.

<Production control means>
The effect control means performs lottery based on the extracted effect random number and other information (for example, information related to the internal winning combination), and determines what is to be executed this time from a plurality of types of effects. Further, the effect control means controls the effect execution means described later so that the determined effect is appropriately executed. In the present embodiment, the sub-control circuit 101 that refers to various tables and determines the effect content based on at least the extracted effect random number and executes the effect according to the determined effect content is the effect control. Configure the means. It should be noted that the above-described “lock” can also be regarded as an aspect of the effect. In this case, the main control circuit 91 constitutes effect control means.

The length is set so that the end portion is not exposed, and the second fixing pin 308 is also inserted into the case body 261 via the lower case side pin insertion hole 302 and the second cover side pin insertion hole 305b. Then, the length is set such that the end of the lower case side pin insertion hole 302 is not exposed. That is, once the first fixing pin 307 and the second fixing pin 308 are inserted into the case main body 261, the first fixing pin 307 and the second fixing pin 308 are left in a state where it is extremely difficult to remove from the case main body 261.

  Therefore, when the case main body 261 is to be opened thereafter, the first breakage portion 303 (303a, 303b) and the second breakage portion 304 (304a, 304b) are broken, and only the cover surface of the cover member 262 is removed. Therefore, if the cover member 262 is removed and the case main body 261 is opened, the trace is surely left by the first fracture portion 303 and the second fracture portion 304.

  In FIG. 14, the upper case member 261a and the lower case member 261b have a step when viewed from the Z direction shown in FIGS. 11 and 12 (that is, the lower case side pin insertion hole 302 is formed in the lower case member 261b. Since the height of the provided side (left side) is higher than the side (right side) where the lower case side pin insertion hole 302 is not provided), depending on the level difference, the upper case side The pin insertion hole 301 and the lower case side pin insertion hole 302, and the first cover side pin insertion hole 305a and the second cover side pin insertion hole 305b are provided at the same height position. However, the present invention is not limited to this. Absent. For example, the upper case member 261a and the lower case member 261b do not have a step when viewed from the Z direction shown in FIGS. 11 and 12 (that is, the lower case side pin insertion hole 302 is provided in the lower case member 261b. When the side (left side) height is substantially the same as the side (right side) where the lower case side pin insertion hole 302 is not provided), the upper case side pin insertion hole 301 and the lower case side pin The insertion hole 302, the first cover side pin insertion hole 305a, and the second cover side pin insertion hole 305b may be provided at different height positions.

  Specifically, the lower case side pin insertion hole 302 and the second cover side pin insertion hole 305b are positioned further downward while maintaining the positions of the upper case side pin insertion hole 301 and the first cover side pin insertion hole 305a. It is good also as being provided in. However, even if the upper case member 261a and the lower case member 261b have a step when viewed from the Z direction shown in FIGS. 11 and 12, the upper case side pin insertion hole 301 and the lower case side pin insertion hole 302, The first cover side pin insertion hole 305a and the second cover side pin insertion hole 305b may be provided at different height positions.

  As described above, according to the substrate case according to the first embodiment, the cover member 262 can be fixed to the case main body 261 simply by inserting the fixing pins 307 and 308. Therefore, the cover member that covers the sealing seal 266 is provided. Even when 262 is provided, the assembly can be easily performed.

  In addition, according to the substrate case according to the first embodiment, when the broken portions 303 and 304 are broken with a tool or the like and the cover member 262 is removed, the trace remains reliably, so that the sealing seal Even if 266 is accessed, it can be easily discovered.

  In addition, according to the substrate case according to the first embodiment, once the fixing pins 307 and 308 are inserted into the case main body 261, the fixing pins 307 and 308 are placed in a state where it is extremely difficult to remove from the case main body 261. Become. As a result, it is very difficult to remove the cover member 262, and thus it is possible to make the access to the seal seal 266 more difficult.

FIG. 22 is a schematic cross-sectional view of the main control board unit, showing a state in which the sliding member 500 is in the second position, and showing a cross-sectional view when viewed from the same direction as FIG. is there. 21 and 22, the part surrounded by the vertical line shows the cross section of the upper case member 261 a, the part surrounded by the horizontal line shows the cross section of the lower case member 261 b, and the part surrounded by the oblique line shows the cover The cross section of the member 400 is shown, and the blacked out portion shows the cross section of the sliding member 500. In FIG. 22, the arrow indicates that the sliding member 500 has moved from the first position to the second position.

  In the main control board unit according to the second embodiment, first, the upper case member 261a and the lower case member 261b are fitted together in the state where the main control board 71 and the sliding member 500 are accommodated, and the third sealing portion 265 is fitted. An inter-case fixing screw 267 is screwed into the upper case member 261a and the lower case member 261b, and then the sealing seal 266 is attached to the back surface of the cover surface of the cover member 400 so as to cover at least the third sealing portion 265. Paste to the side.

  Next, the cover member 400 to which the seal seal 266 is attached is attached to the case main body 261. At this time, although the restricting portion 402 (402a, 402b) is locked to the upper case member 261a and the upward movement of the cover member 400 is temporarily restricted, the cover member 400 is moved into the case by the elasticity of the cover member 400. The main body 261 is still detachable.

  Next, the sliding screw 404 is screwed into the screw screwing portion 501 on the screw insertion hole 311 side through the screw insertion hole 311 and fixed, and the sliding screw 405 is screwed through the screw insertion hole 312. The screw is inserted into the screw screw insertion portion 501 on the insertion hole 312 side and fixed with screws. Thereby, the sliding member 500 moves from the first position to the second position, and the lower case member 261b and the sliding member 500 are fixed.

  Here, the upper case-side concave portion extends in the Z direction shown in FIGS. 15 to 17 (that is, the lateral direction when viewed from the X direction or the Y direction) on the sliding surface inside the upper case member 261a positioned above. 601 (601a, 601b) are provided, and when the sliding member 500 moves to the second position, the slope portion of the locking portion 503a enters the upper case-side recess 601 and the corner of the upper case-side recess 601 is engaged. The locking portion 503a is locked to the upper case-side recess 601 (601a, 601b) by entering the inner corner formed by the vertical surface of the locking portion 503a and the rib.

  Further, the lower case-side concave portion 602 extends on the sliding surface inside the lower case member 261b located below in the Z direction (that is, the lateral direction when viewed from the X direction or the Y direction) shown in FIGS. (602a, 602b) are provided, and when the sliding member 500 moves to the second position, the slope portion of the locking portion 503c enters the lower case side concave portion 602 and the corner of the lower case side concave portion 602 is locked. The locking portion 503c is locked to the lower case-side recess 602 (602a, 602b) by entering the inner corner formed by the vertical surface of the portion 503c and the rib.

  Although not shown in FIGS. 21 and 22, the sliding surface inside the lower case member 261b located on the side is perpendicular to the Z direction shown in FIGS. , The lower case side concave portion is provided over the vertical direction when viewed from the X direction or the Y direction (hereinafter, the lower case side concave portion provided on the sliding surface on the left side as viewed from the X direction is referred to as the lower case). When the sliding member 500 is moved to the second position, the side concave portion 603 is defined as a lower case side concave portion provided on the sliding surface on the right side when viewed from the X direction. The slope portion enters the lower case side recess 603, and the corner of the lower case side recess 603 enters the inner corner formed by the vertical surface of the locking portion 503b and the rib, so that the locking portion 503b becomes the lower case side recess 603. Locked in It is. In addition, the slope portion of the locking portion 503d enters the lower case-side recess 604, and the corner of the lower case-side recess 604 enters the inner corner formed by the vertical surface of the locking portion 503d and the rib. 503d is locked to the lower case side recess 604.

  That is, when the sliding member 500 moves to the second position, each of the locking portions 503a, 503b, 503c, and 503d includes the upper case side concave portion 601, the lower case side concave portion 602, the lower case side concave portion 603, and the lower case side concave portion. As a result, the sliding member 500 cannot move from the second position.

  Note that the upper case member 261a may be located on the side of the sliding member 500. In this case, the lower case side recess 603 and the lower case side recess are provided on the sliding surface inside the upper case member 261a. It is good also as providing 604 (in other words, the upper case side recessed part 603 and the upper case side recessed part 604).

  The shapes of the locking portions 503a, 503b, 503c, and 503d are not limited to those described above, and the upper case side concave portion 601, the lower case side concave portion 602, the lower case side concave portion 603, and the lower case side concave portion 604 are slid. Any shape can be adopted as long as the moving member 500 is locked so as not to move from the second position.

  Further, instead of the upper case side recess 601, the lower case side recess 602, the lower case side recess 603 and the lower case side recess 604, an upper case side protrusion is provided on the sliding surface inside the upper case member 261 a, and the lower case member It is good also as providing a lower case side convex part in each of the sliding surfaces inside 261b. In this case, the shape of the locking portions 503a, 503b, 503c, and 503d is set so that the sliding member 500 cannot move from the second position with respect to the upper case side convex portion and the lower case side convex portion. What is necessary is just to make it the shape stopped.

  21 and 22, the screw insertion holes 311 and 312 are provided on the left and right sides of the lower case member 261b, respectively, but the present invention is not limited to this. For example, the screw insertion holes 311 and 312 may be provided below the lower case member 261b in FIGS. In this case, the arrangement of the screw screw insertion portion 501 may be changed according to the positions of the screw insertion holes 311 and 312 and the configuration of the sliding member 500 may be changed as appropriate. In this case, the upper side in FIGS. 21 and 22 (that is, the cover member 400 side) is the first position of the sliding member 500, and the lower side in FIGS. 21 and 22 (that is, the screw insertion holes 311 and 312 are provided). You may comprise so that the side provided) may become the 2nd position of the sliding member 500. FIG.

  When the sliding member 500 moves to the second position, the protruding piece 504 is inserted through the insertion portion 403, and the cover member 400 and the sliding member 500 are engaged. Here, since the sliding member 500 is locked by the locking portion 503 so as not to move from the second position, even if the sliding screw 404 or 405 is loosened, the sliding member 500 does not slide with the cover member 400. The engagement with the moving member 500 is not released.

  Further, at this time, the surface of the cover member 400 where the restricting portions 402 (402a, 402b) and the insertion portions 403 (403a, 403b) are provided is outside (ie, the surface where the protruding pieces 504 of the sliding member 500 are provided). In the side where the restricting portion 402a and the insertion portion 403a are provided, it is biased in the Y direction, and in the side where the restriction portion 402b and the insertion portion 403b are provided, it is biased in the X direction. For this reason, the restricting portion 402 (402a, 402b) is completely locked to the upper case member 261a, and the upward movement of the cover member 400 is restricted.

  Therefore, when the case body 261 is to be opened thereafter, a part of the sealing seal 266 is broken from the through hole 401 to remove the case fixing screw 267, and the upper case member 261a and the cover member 400 together with the lower case member 261b. Therefore, if the case main body 261 is to be opened, the seal seal 266 is broken and the trace remains reliably.

  As described above, according to the substrate case according to the second embodiment, the cover member 400 can be fixed to the case main body 261 simply by screwing the sliding screws 404 and 405, so that the sealing seal 266 is covered. Even when the cover member 400 is provided, it can be easily assembled.

  Further, according to the substrate case according to the second embodiment, when the sliding screws 404 and 405 are screwed, the sliding member 500 cannot move from the second position after moving from the first position to the second position. It becomes. As a result, it is extremely difficult to remove the cover member 400, so that the access to the seal seal 266 can be made more difficult.

  Further, according to the substrate case according to the second embodiment, when the sliding member 500 moves to the second position, the protruding piece 504 is inserted through the insertion portion 403 accordingly, and the cover member 400, the sliding member 500, Are engaged. Therefore, removal (movement) of the cover member 400 can be regulated with a simple configuration.

  Further, according to the substrate case according to the second embodiment, the removal (movement) of the cover member 400 is also restricted by the restriction portion 402 when at least the sliding member 500 is in the second position. Therefore, removal (movement) of the cover member 400 can be regulated more firmly.

  Further, according to the substrate case according to the second embodiment, when the sliding member 500 moves to the second position, it becomes extremely difficult to access the third sealing portion 265 without passing through the through hole 401. Accordingly, since the trace is surely left by the tearing of the seal seal 266, even if the third seal portion 265 is accessed, it can be easily detected.

  The gaming machine according to the present embodiment and the board case according to the first embodiment and the second embodiment of the present embodiment included in the gaming machine have been described above, but these embodiments are presented as examples. And are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, combinations, replacements, and changes can be made without departing from the spirit of the invention.

  For example, in the present embodiment, the pachislot machine 1 is described as an example of the gaming machine, but the present invention is not limited to this, and a pachinko machine may be adopted as the gaming machine. In the pachinko machine, a game board is attached to a frame body, and a front door formed of a transparent material is attached to the front side of the pachinko machine so as to be freely opened and closed. Since these are exterior bodies of the gaming machine, the main control board case 55 according to the present embodiment may be disposed therein. As an example, the main control board case 55 according to the present embodiment may be attached to the back side of the game board (that is, the opposite side of the front door in the game board).

  For example, in the present embodiment, the main control board case 55 is attached to the middle door 41. However, the present invention is not limited to this, and the main control board case 55 may be attached to the inside of the cabinet 2a. Good. In this case, the main control board case 55 may be attached at the position of the cabinet-side speaker 42, and when a shelf board is provided in the cabinet 2a, it may be attached on the upper side or the lower side of the shelf board. Good.

  Further, for example, in the present embodiment, the inlet portion is formed on the seal seal 266. However, the present invention is not limited to this, and the code portion (for example, a barcode portion or a two-dimensional code portion) is not limited to this. It is good also as forming. In this case, it can be determined by an external device (for example, a barcode reader, a two-dimensional code reader, or a portable device having these functions) whether or not the attached seal seal 266 is a genuine seal. What should be done. Further, a seal in which no inlet portion or cord portion is formed may be employed as the seal seal 266. Even with such a seal, the object can be achieved in that it can reliably leave a broken mark. However, it is desirable that the seal is subjected to an appropriate copy guard process (for example, hologram printing) so that it cannot be easily copied.

  Further, for example, the substrate case according to the first embodiment further includes a cap that covers the inside of the upper case side pin insertion hole 301 and the lower case side pin insertion hole 302, and the first fixing pin 307 is further provided. In addition, it may be difficult to access the second fixing pin 308.

  Further, for example, in the substrate case according to the first embodiment, the first fixing pin 307 and the second fixing pin 308 are further provided with a retaining mechanism at the distal end or the peripheral surface of the insertion direction side. The first fixing pin 307 and the second fixing pin 308 may be more difficult to take out from the case body 261.

  Further, for example, in the substrate case according to the first embodiment, when the first fixing pin 307 and the second fixing pin 308 are further inserted into the case body 261, an adhesive or solvent is applied to the peripheral surface thereof.
