On the game panel 30, three vertically long display windows 31L, 31M, 31R are formed side by side. The display windows 31L, 31M, 31R are made of a transparent or translucent material, and the inside of the slot machine 10 is visible through the display windows 31L, 31M, 31R. Note that the display windows 31L, 31M, 31R may be integrated into a single display window.

  As shown in FIG. 3, the inside of the housing 11 is divided into upper and lower parts by a partition plate 40, and a reel unit 41 constituting a variable display means is attached to the upper part of the partition plate 40. The reel unit 41 includes a left reel 42L, a middle reel 42M, and a right reel 42R that are each formed in a cylindrical shape (annular shape). The reels 42L, 42M, and 42R may be configured as at least an endless belt, and are not limited to the cylindrical shape (annular shape). The reels 42L, 42M, and 42R are rotatably supported so that the central axis thereof is the rotation axis of the reel. The rotation axes of the reels 42L, 42M, 42R are arranged on the same axis extending in the substantially horizontal direction, and the reels 42L, 42M, 42R correspond to the display windows 31L, 31M, 31R in a one-to-one correspondence. . Therefore, a part of the surface of each reel 42L, 42M, 42R is in a visible state through the corresponding display window 31L, 31M, 31R. When the reels 42L, 42M, 42R rotate forward, the surfaces of the reels 42L, 42M, 42R are projected through the respective display windows 31L, 31M, 31R as if moving from top to bottom.

  These reels 42L, 42M, 42R are respectively connected to stepping motors 61L, 61M, 61R, and the respective reels 42L, 42M, 42R are driven individually by driving the stepping motors 61L, 61M, 61R. It is configured to be rotationally driven. Since each of the reels 42L, 42M, and 42R has the same configuration, the left reel 42L will be described as an example with reference to FIG. 6. FIG. 6 is an assembly perspective view of the left reel 42L.

  The left reel 42L includes a cylindrical skeleton member 50 forming a cylindrical cage, and a belt-shaped belt endlessly wound on the outer peripheral surface thereof. Then, it is attached to the cylindrical skeleton member 50 via a pair of seal portions formed along both long sides of the belt so as to maintain the rolled state. A large number of patterns as identification information are printed at equal intervals on the outer peripheral surface of the belt. A boss portion 51 is formed at the center of the cylindrical skeleton member 50, and is attached to the drive shaft of the left reel stepping motor 61L via a disc-shaped boss reinforcing plate 52. Therefore, when the drive shaft of the left reel stepping motor 61L rotates, the cylindrical skeleton member 50 rotates about the drive shaft so as to rotate, and the left reel 42L circulates along the annular reel surface. Has become.

  The left reel stepping motor 61L is fixed by a screw 54 to a side surface of a motor plate 53 which is arranged upright in the reel unit 41 (FIG. 3). A reel index sensor (rotational position detection sensor) 55 in which a light emitting element 55a and a light receiving element 55b are held at a predetermined interval is installed on the motor plate 53. On the other hand, a boss reinforcing plate 52 integrated with the left reel 42L is fixed with a screw 57 to a base end portion 56b of a sensor cut van 56 extending in the radial direction. The tip portion 56a of the sensor cut bun 56 is bent at a substantially right angle and is aligned so that it can pass between both elements 55a and 55b of the reel index sensor 55. Then, each time the left reel 42L makes one rotation, the reel index sensor 55 detects the passage of the tip portion 56a of the sensor cut bun 56, and a detection signal is output to the main control device 131 described later each time it is detected. Therefore, the main controller 131 can confirm and correct the angular position of the left reel 42L for each rotation based on this detection signal.

  The stepping motor 61L is set so as to make one rotation by giving a drive signal of 504 pulses (also referred to as an excitation signal or an excitation pulse; the same applies hereinafter), and the rotation position of the stepping motor 61L, that is, the left side, is set by this excitation pulse. The rotation position of the reel 42L is controlled.

  On each belt of each reel 42L, 42M, 42R, a plurality of symbols, specifically 21 symbols, are drawn in the long side direction (circulation direction) thereof. Therefore, it takes 24 pulses (= 504 pulses / 21 symbols) to switch from one symbol to the next symbol at a predetermined position. Then, by the number of pulses from the time when the detection signal of the reel index sensor 55 is output, it is possible to recognize which symbol is visible from the display window 31L or to visually recognize any symbol from the exposure window 31L. It is possible to perform control such that the state is changed.

  Of the symbols attached to the reels 42L, 42M, 42R, the number of symbols that can be visually recognized through the display windows 31L, 31M, 31R is mainly determined by the vertical lengths of the display windows 31L, 31M, 31R. It is limited to a predetermined number. In this embodiment, each reel has three reels. Therefore, in a state where all the reels 42L, 42M, 42R are stopped, 3 × 3 = 9 symbols are visible to the player.

  Here, the symbols attached to the reels 42L, 42M, and 42R will be described. FIG. 7 shows the symbol arrangement drawn on the belts wound around the left reel 42L, the middle reel 42M, and the right reel 42R, respectively. As shown in the figure, each reel 42L, 42M, 42R is provided with 21 symbols in a row. The numbers 1 to 21 are assigned to the reels 42L, 42M, and 42R, but these are provided for convenience of description, and are not actually assigned to the reels 42L, 42M, and 42R. . However, in the following description, the corresponding numbers will be used for description.

  As the symbols, there are a "7" symbol (for example, 20th left belt) and a "youth" symbol (19th for left belt) as the first special symbol for shifting to the big bonus game. Further, there is a "BAR" symbol (for example, 14th left belt) as a second special symbol for shifting to the regular bonus game. In addition, there is a "replay" symbol (for example, eleventh left belt) as the third special symbol for shifting to the replay game. In addition, a "watermelon" symbol (for example, the left belt ninth), a "bell" symbol (for example, the left belt eighth), and a "cherry" symbol (for example, left There is a 4th belt). Then, as shown in FIG. 7, in the belts wound around the reels 42L, 42M, and 42R, the numbers and arrangement order of various symbols are completely different.

  Each reel 42L, 42M, 42R of the reel unit 41 is an example of a variable display means for variably displaying identification information, and constitutes a main display section. However, the variable display means may have a configuration other than this. For example, other mechanical reel configurations such as a type in which the belt is rotated instead of rotating may be used, and instead of or in addition to the mechanical reel configuration, a liquid crystal display, a dot matrix display, etc. A device for variably displaying the identification information by electrical display such as may be provided, and in this case, it is possible to give a wide variety of display forms.

  The game panel 30 is provided with a combination line of three lines in parallel in the lateral direction and two lines in the diagonal direction so as to connect the display windows 31L, 31M, 31R, a total of five combination lines. Of course, the maximum number of combined lines may be 6 or more or less than 5, and the maximum number of combined lines may be changed according to a predetermined condition. Corresponding to each of these combination lines, effective line display portions 32, 33, 34 are provided on the left side of the display windows 31L, 31M, 31R viewed from the front. When the central horizontal line (central line) of the combination lines is activated, the first activated line display unit 32 is informed and displayed by lighting or the like. When the upper and lower horizontal lines (upper line and lower line) of the combination lines are activated, the second effective line display unit 33 is informed and displayed by lighting or the like. When the pair of diagonal lines (downward rightward line and upward rightward line) of the combination lines are activated, the third effective line display unit 34 is informed by lighting or the like. Then, when the symbols are stopped in a predetermined combination on the activated combination line, that is, the activated line, the prize is won, and a predetermined medal payout process, a transition process to a specific game, and the like are executed.

  Here, the payout number relating to each symbol when a prize is won will be described. Regarding small winning symbols, if the "watermelon" symbol is aligned with the left, middle and right on the activated line, 15 medals are paid out, and if the "bell" symbol is aligned with the left, medium and right on the activated line. Pays out eight medals, and when the "cherry" symbol on the left reel 42L stops on the activated line, two medals are paid out. That is, the "cherry" symbols on the middle reel 42M and the right reel 42R are unrelated to the medal payout. Further, since only the "cherry" symbol is paid out regardless of the combination with the other symbols, the "reel" symbol is placed at a position where the plural effective lines of the left reel 42L overlap (specifically, the upper stage or the lower stage). When the "cherry" symbol is stopped, medals are paid out only by multiplying the number of overlapping effective lines, and as a result, four medals are paid out in the present embodiment.

  Regarding other symbols, if the "7" symbol or the "youth" symbol, which is the combination of the first special symbol (big bonus symbol), is aligned with the left, middle and right on the effective line in the same symbol. 15 medals are paid out, and 15 medals are paid out even when the "BAR" symbol, which is a combination of the second special symbol (regular bonus symbol), is aligned with the left, middle, and right on the activated line. In the present embodiment, for example, there may be a case where the “7” symbol and the “cherry” symbol are established at the same time, but in such a case, the medal payout is 15 coins. This is because the maximum number of medals to be paid out once is set to 15.

  Furthermore, when the "replay" symbol, which is a combination of the third special symbols, is aligned with the left, middle, and right on the activated line, the medal payout is not performed. In other cases, that is, when the "cherry" symbol of the left reel 42L does not stop on the activated line and the same symbols as the left, middle, and right are not aligned on the activated line, no medal is paid out.

  On the lower left side of the game panel 30, there is provided a start lever 71 which is operated to start the rotation of the reels 42L, 42M, 42R all at once (not necessarily at the same time). The start lever 71 constitutes start operation means or start operation means operated to start rotation of the reels 42L, 42M, 42R, that is, to start variable display. The start lever 71 is a lever that the player pushes with his / her hand when starting the game, and automatically returns to the original position after the hand is released. When the start lever 52 is operated while a medal is inserted, the reels 42L, 42M and 42R start rotating all at once.

  On the right side of the start lever 71, button-shaped stop switches 72, 73, 74 operated to individually stop the rotating reels 42L, 42M, 42R are provided. The stop switches 72, 73, 74 are arranged directly below the display windows 31L, 31M, 31R corresponding to the reels 42L, 42M, 42R to be stopped. The stop switches 72, 73, 74 constitute stop operation means operated to stop the variable display based on the rotation of the reels 42L, 42M, 42R. The stop switches 72, 73, 74 are in a state in which they can be stopped when the reels 42L, 42M, 42R are rotated at a constant speed. It is informed that it is possible, and is turned off when the rotation is stopped.

  On the lower right side of the display windows 31L, 31M, 31R, a medal insertion slot 75 for inserting a medal as an investment value is provided. The medal insertion slot 75 constitutes an input means for inputting the investment value. Further, if attention is paid to the point that the medal insertion slot 75 directly inserts a medal by the player, it can be said that it constitutes a direct input means for directly inputting the investment value.

  The medals inserted from the medal insertion slot 75 are guided to either the storage passage 81 or the discharge passage 82 by the selector 84 provided on the back surface of the front door 12 as passage switching means. That is, the selector 84 is provided with a medal passage switching solenoid 83, which is set to the discharge passage 82 side when the medal passage switching solenoid 83 is not excited, and is switched to the storage passage 81 side when excited. The medal guided to the storage passage 81 is guided to the hopper device 91 housed inside the housing 11. On the other hand, the medals guided to the discharge passage 82 are guided to the medal tray 18 from the medal discharge port 17 provided at the lower front portion of the front door 12 and returned to the player.

  The hopper device 91 as a payout means for giving medals to the player is composed of a storage tank 92 for storing the medals and a payout device 93 for paying out the medals to the player. The payout device 93 rotates a medal payout rotating plate (not shown) to eject the medals to an opening 94 provided in the central right portion of the ejection passage 82, and to the medal tray 18 via the ejection passage 82. Are to be paid out. Further, on the right side of the hopper device 91, a spare tank 95 is provided for avoiding that a predetermined amount or more of medals are stored in the storage tank 92. Inside the storage tank 92 of the hopper device 91, a guide plate 96 for discharging medals from the storage tank 92 to the spare tank 95 is provided. Therefore, when the medals are stored at a height higher than the height at which the guide plate 96 is provided, the medals are stored in the spare tank 95.

  A button-shaped return switch 76 is provided below the medal insertion slot 75. The return switch 76 is a switch that is pressed when medals inserted into the medal insertion slot 75 are jammed in the selector 84, and when this switch is pressed, the selector 84 is mechanically interlocked and operates. The medals clogged in 84 are returned from the medal discharge port 17.

  On the lower left side of the display windows 31L, 31M, 31R, there is provided a button-shaped first credit insertion switch 77 for inserting three credited virtual medals as investment value at one time. Further, on the left side of the first credit insertion switch 77, a second credit insertion switch 78 and a third credit insertion switch 79 are provided as button-shaped switches smaller than the switch 77. The second credit insertion switch 78 is for inserting two credited virtual medals at a time, and the third credit insertion switch 79 is for inserting one virtual medal. The credit insertion switches 77 to 79 together with the medal insertion slot 75 constitute input means for inputting investment value. Also, paying attention to the fact that the medal insertion slot 75 involves the operation of directly inserting a medal by the player, whereas the credit insertion switches 77 to 79 only involve the operation of inserting a virtual medal based on the stored memory. It can be said that it constitutes an indirect input means for indirectly inputting the investment value.

  The first credit insertion switch 77 has a built-in lamp (not shown) as a light emitting member in order to prompt that the maximum number of medals (three coins) that can be inserted per game is not reached. The lamp is turned on when the switch operation of the first credit insertion switch 77 is valid and prompts the operation of the switch 77, but when there is no credited virtual medal or three medals have already been inserted. It is turned off under the situation. Here, instead of the above lighting, it may be blinked to make it easier for the player to recognize the medal insertion.

  On the left side of the start lever 71, a button-shaped changeover switch 80 is provided. The changeover switch 80 is in a toggle type in which it is turned on when pressed once, turned off when pressed again, and switched on and off each time the pressing operation is performed. The changeover switch 80 is operated in order to change the handling mode of the inserted medals that have been inserted into the medal insertion slot 75 in an amount larger than the required amount and the acquired medals returned to the player as a result of a predetermined game.

  When the changeover switch 80 is in the ON state, a surplus inserted medal until reaching a predetermined maximum value (for example, 50 medals) or an obtained medal at the time of winning is set to be stored and stored as a credit medal. It will be. When the changeover switch 80 is in the off state, the "direct mode" is set in which the surplus inserted medals and the medals acquired at the time of winning are paid out as the actual medals. If there are credit medals when the credit mode is switched to the direct mode, the corresponding credit medals are paid out as actual medals. In this way, the player can execute the game in a format according to his / her preference by switching between the credit mode and the direct mode. The changeover switch 80 constitutes a changeover operation means for changing over the handling type of the input value and the game value. Further, if attention is paid to the function of paying out the credited virtual medal as an actual medal, it can be said that the changeover switch 80 constitutes a settlement operation means for actually paying out the stored and stored game value. It should be noted that, in addition to the configuration in which the "credit mode" and the "direct mode" are switched by operating the changeover switch 80, the virtual medals stored and stored are paid out when the changeover switch 80 is operated by always keeping the "credit mode". You may make it function as a settlement switch only.

  Below the display windows 31L, 31M, 31R of the game panel 30, a remaining number display section 35 that displays the number of medals that are activated and stored in the credit mode, and a special game state such as a big bonus or a regular bonus. For example, a game number display section 36 for displaying the number of remaining games and the like, and an acquired number display section 37 for displaying the number of acquired medals are respectively provided. Although these display portions 35 to 37 are composed of 7-segment displays, they can be replaced by liquid crystal displays or the like.

  Here, the procedure for betting medals will be described. In both the direct mode and the credit mode, a bet is made when a medal is inserted from the medal insertion slot 75 at the start of the game.

  That is, when the first medal is inserted into the medal insertion slot 75, the first effective line display portion 32 lights up, and the corresponding center line becomes the effective line, and the second medal becomes the medal insertion slot. When it is thrown into 75, the second effective line display section 33 is further turned on, and a total of three combination lines including the upper line and the lower line corresponding thereto become effective lines, respectively, and the third medal becomes the medal. When inserted into the slot 75, the third effective line display unit 34 is further turned on, and all five combined lines including a pair of diagonal lines corresponding thereto become effective lines.

  Further, when four or more medals are inserted into the medal insertion slot 75, the surplus medals of more than three medals are switched to the discharge passage 82 by the selector 84 if the mode at that time is the direct mode. It is returned from the outlet 17 to the medal tray 18. On the other hand, in the credit mode, the number of savings is displayed in the remaining number display section 35 as well as being saved inside the slot machine. The upper limit of the number of stored coins is set (for example, 50 coins), and when the number of coins exceeding that is inserted, the coins are returned from the medal discharge port 17 to the medal tray 18.

  In addition, when a game is played in the credit mode and the number of stored coins is displayed on the remaining number display section 35, even when one of the first to third credit insertion switches 77 to 79 is pressed, the virtual A bet has been placed because a medal has been inserted.

  When the third credit insertion switch 79 is pressed, the number displayed on the remaining number display section 35 is decremented by 1 as one virtual medal has been inserted, and the first activated line display section 32 is displayed. It lights up and the center line becomes the effective line. When the second credit insertion switch 78 is pressed, the number displayed on the remaining number display section 35 is decremented by two as the fact that two virtual medals have been inserted, and the first effective line display section 32 and The second effective line display portion 33 lights up, and a total of three combined lines become effective lines. When the first credit insertion switch 77 is pressed, the number displayed on the remaining number display section 35 is decremented by 3, which indicates that three virtual medals have been inserted, and all the activated line display sections 32 to 34 is turned on, and a total of 5 combination lines become effective lines.

  In addition, when the virtual medal to be inserted when any of the first to third credit insertion switches 77 to 79 is pressed, for example, when the display of the remaining number display unit 35 is 2, When the credit insertion switch 77 is pressed, the remaining number display section 35 decrements all the numerical values to 0, and bets are made for the virtual medals that can be inserted.

  A key attachment fitting 261 having a key insertion hole 261a at its tip is attached and fixed near the step 244 of the movable base plate 212. The key mounting bracket 261 has a root portion fixed to the movable base plate 212 by a fixture such as a screw (not shown).

  Next, the configuration of main controller 131 will be described in detail. FIG. 13 is an exploded perspective view showing, in an enlarged manner, each of the case bodies 271, 272 and the main board 273 that form the main controller 131.

  A wiring pattern (not shown) is provided on the main board 273, and various electronic components including an IC chip 274 such as a CPU and a ROM, an input / output connector 275, an inspection connector 276, etc. are mounted. In particular, the IC chip 274 adopts a vertical device such as a so-called ZIP (Zigzag In-line Package) type structure or a SIP (Single In-line Package) structure, which is mounted in a state where the chip stands on the substrate surface. The identification information such as the manufacturer and the product number, unique information, etc. are printed on the side surface of the chip. The main board 273 is fixed to the front case body 271 with screws 277 through a plurality of small holes provided at the corners.

  The front case body 271 has a main board housing portion capable of housing a relatively tall electronic component or the like on the main board 273, and a step portion 281 that is one step lower is formed at the peripheral edge portion. The step portion 281 is formed with a plurality of connector insertion holes 282 through which the input / output connectors 275 on the main board 273 are inserted. Reference numeral 283 is an opening communicating with the inspection connector 276 on the main board 273. Although illustration is omitted, a large number of ventilation holes are formed in the ceiling portion of the front case body 271 and the like.

  Further, on the upper and lower edges of the long side portion of the front case body 271, there are provided ridge portions 285 that linearly extend along the side wall of the front case body 271, and a plurality of ridge portions 285 are provided inside the ridge portions 285. The long holes 286 are provided so as to be arranged in a line at a predetermined interval.

  A vertical rectangular cutout square hole portion 290 is provided at the left end portion (left side of the main board housing portion) of the front case body 271, and the cutout square hole portion 290 forms a plurality of first sealing portions. (Four in the present embodiment) sealing coupling portions 291 are provided so as to be aligned in a vertical line. Its peripheral configuration is shown in an enlarged manner in FIG. The seal coupling part 291 has a tubular shape, and is connected to the front case body 271 by the connecting parts 292 on both left and right sides. By cutting the connecting part 292, the seal connecting part 291 can be cut off from the front case body 271. Similarly, the cutout square hole portion 290 is provided with a plurality of (two in the present embodiment) sealing coupling portions 293 that constitute the second sealing portion so as to sandwich the plurality of sealing coupling portions 291. The seal joining portion 293 has a cylindrical shape and is connected to the front case body 271 by a connecting portion 294. By cutting the connecting portion 294, the seal connecting portion 293 can be cut off from the front case body 271.

  In such a case, since the seal connecting portions 291 and 293 forming the first and second seal portions are provided in the cutout square hole portion 290 formed in the front case body 271, the seal connecting portions 291 and 293 should be projected to the side of the substrate case. Unlike the conventional general configuration in which the sealing portion is provided in the above, there is no inconvenience such as the sealing coupling portions 291 and 293 protruding laterally and becoming an obstacle. Further, since the seal coupling portions 291 and 293 do not protrude to the side, there is no possibility that the seal coupling portions 291 and 293 may be hit and damaged when the main control device 131 is handled alone.

  A left end portion of the front case body 271 is a leading portion when the main control device 131 is slidably mounted on the movable base plate 212, and a locking claw portion 295 is provided at the tip portion thereof, and a locking claw is provided. A pair of screw hole portions 296 are provided so as to sandwich the portion 295. When the main controller 131 is mounted on the movable base plate 212, the locking claw portions 295 are locked in the locking hole portions 247 provided on the movable base plate 212. Further, the screw hole portion 296 and the through hole 248 provided in the movable base plate 212 are aligned with each other, and in this state, the machine screw 297 is screwed into the through hole 248 and the screw hole portion 296.

  On the left side of the cutout square hole portion 290 of the front case body 271, a surrounding frame 332 that partitions and forms the sticking surface of the seal S is formed. When the main controller 131 is mounted on the movable base plate 212, the surrounding frame 332 of the front case body 271 and the surrounding frame 331 formed on the movable base plate 212 are integrated into a rectangular frame-like enclosure. A frame is formed.

  Returning to the description of FIG. 13, a plurality of (two in the present embodiment) seal joining portions 301 that form the third seal portion are provided at the right end portion of the front case body 271. The seal joining portion 301 has a cylindrical shape and is connected to the front case body 271 by the connecting portion 302. By cutting the connecting portion 302, the seal joining portion 301 can be cut off from the front case body 271.

  Further, a key fitting 305 is attached and fixed to the right end of the front case body 271. The key attachment fitting 305 has a root portion fixed to the front case body 271 by a fixture such as a screw (not shown). The front end portion of the key mounting member 305 is bent obliquely outward, and a key insertion hole 305a is formed in the bent portion (see FIG. 17 and the like).

  On the other hand, in the back case body 272, a plurality of hook portions 312, which stand up in the board height direction and have L-shaped tips, are provided at predetermined intervals on both upper and lower sides of the figure with the bottom plate portion 311 interposed therebetween. Has been. The hook portions 312 are provided at the same intervals as the long holes 286 of the front case body 271, and both the case bodies 271, 272 are formed by the long holes 286 of the front case body 271 and the hook portions 312 of the back case body 272. Is being assembled.

  FIG. 18 (an end view taken along the line BB in FIG. 8) shows an assembly structure of the front case body 271 and the back case body 272. As shown in FIG. 18, the hook portion 312 of the back case body 272 is inserted into the long hole 286 of the front case body 271, and in that state, the hook portion 312 is formed in the long hole 286 of the front case body 271 side. It is locked by the locking portion 286a. As a result, the front case body 271 is held on the back case body 272 without rising. Incidentally, although FIG. 18 shows a state in which the main control device 131 is assembled to the pedestal device 210 and the front case body 271 cannot be slid laterally with respect to the back case body 272, the pedestal device 210 is shown. Assuming that the front case body 271 is not assembled to the back case body 272, the front case body 271 can be separated from the back case body 272 by sliding the front case body 271 rightward in FIG. The front case body 271 is moved along the arrow P therein).

  The movable base plate 212 is provided with a return portion 212a at the left end portion in FIG. 18, and the return portion 212a is provided below the shaft support portion 216 of the fixed base plate 211 (actually, the hole portion 216b shown in FIG. 12). It is designed to enter. Therefore, even if the support pin 217 is cut midway or the support pin 217 is pulled out, the movable base plate 212 does not float above the fixed base plate 211 by itself.

  Returning to the explanation of FIG. 13 again, a pair of upper and lower extending portions 314a and 314b are provided at the left end portion of the back case body 272 so as to extend to the left of the bottom plate portion 311. Each of the parts 314a and 314b is provided with a seal joining part 315 that constitutes a second seal part. The seal coupling portion 315 has a cylindrical shape whose bottom is closed by the same surface as the bottom plate portion 311 and is opened only on the front side of the drawing. The extending portions 314a and 314b are provided separately from each other in the vertical direction, and the space between the extending portions 314a and 314b is provided to avoid interference with the plurality of seal coupling portions 251 provided on the movable base plate 212. It is an empty space.

  A key attachment fitting 316 having a key insertion hole 316a at the tip is attached and fixed to the extension 314a on the upper side of the drawing. The key attachment fitting 316 has a root portion fixed to the back case body 272 by a fixture such as a screw (not shown).

  In addition, a plurality (two in the present embodiment) of seal coupling portions 317 forming the third seal portion are provided on the right end of the back case body 272. The seal joining part 317 is connected to the back case body 272 by a connecting part 318. By cutting the connecting portion 318, the seal connecting portion 317 can be cut off from the back case body 272.

  Here, a sealing structure for suppressing unauthorized removal of the main control device 131 and the base device 210 will be described. In the present embodiment, three types of sealing parts, each having a different sealing structure, are provided, and for convenience, they are referred to as a first sealing part, a second sealing part, and a third sealing part, and will be described in order. FIG. 19 corresponds to an end view taken along the line CC of FIG. 8 and shows a sectional structure of the first sealing portion. FIG. 20 is an end view taken along the line DD of FIG. 8 and shows a sectional structure of the second sealing portion. FIG. 21 is an end view taken along the line EE of FIG. 8 and shows a sectional structure of the third sealing portion.

  First, the structure of the first sealing portion will be described with reference to FIG. In FIG. 19, (a) shows the state before sealing, (b) shows the sealed state, and (c) shows the unsealed state. The first sealing portion can be in a sealed state by coupling the sealing coupling portion 291 provided on the front case body 271 and the sealing coupling portion 251 provided on the movable base plate 212. The side coupling section 291 "and the latter are paraphrased as" receiving side coupling section 251 ", and the description will proceed.

  As shown in FIG. 19A, a hole 291a (for convenience, referred to as an upper hole) penetrating in the up-down direction is formed in the insertion side coupling portion 291 of the front case body 271. The receiving side coupling portion 251 of the plate 212 is formed with a hole portion 251a (for convenience, referred to as a lower hole portion) that coaxially communicates with the upper hole portion 291a. A step portion 291b is provided at the entrance of the upper hole 291a, and a diameter-expanded portion 251b having a diameter larger than that of the upper hole 291a is provided at the entrance of the lower hole 251a.

  In addition, reference numerals 251c and 291c are semi-circular return portions provided in the receiving-side coupling portion 251 and the insertion-side coupling portion 291, respectively (the return portion 251c is provided in the front of the main control device 131 in the sliding direction and the return portion is provided). 291c is provided on the rear side in the sliding direction of the main control device 131), and the connecting portions 251 and 291 abut on the return portions 251c and 291c. By the return portions 251c and 291c, the facing joint surfaces of the coupling portions 251 and 291 are hidden.

  When the sealing process is performed, as shown in FIG. 19B, the holes 291a and 251a of the insertion-side coupling portion 291 and the receiving-side coupling portion 251 are made of, for example, synthetic resin and formed into a substantially hollow cylindrical shape. The sealing pin member 321 is inserted. As shown in FIG. 16, the sealing pin member 321 has a hollow cylindrical portion 321a, a flange-shaped head portion 321b, and an elastically deformable locking claw portion 321c provided in, for example, two positions on the cylindrical portion 321a. In the normal state, the locking claw portion 321c projects outward from the outer periphery of the tubular portion 321a, and the locking claw portion 321c can be retracted into the tubular portion 321a by applying an external force. There is. Identification information (for example, an identification code) for each main controller 131 is attached to the head 321b of the sealing pin member 321.

  When the sealing pin member 321 is inserted, the locking claw portion 321c of the sealing pin member 321 is elastically deformed, and the head portion 321b is inserted until it contacts the step portion 291b at the entrance of the upper hole portion. At this time, the locking claw portion 321c of the sealing pin member 321 reaches the enlarged diameter portion 251b of the lower hole portion 251a, so that the locking claw portion 321c rises, and the rear end surface of the locking claw portion 321c is connected to the insertion side. It is locked to the tip surface of the portion 291. As a result, the sealing of the first sealing portion is completed, and the sealing pin member 321 after sealing is prevented from falling off.

  When the seal of the first sealing portion is to be released when the main control device 131 has a defect or is inspected, the insertion side coupling portion 291 and the front case body 271 are connected to each other as shown in FIG. The connecting portion 292 to be connected is cut with a tool such as a nipper. At this time, only the tip of the sealing pin member 321 is inserted into the receiving side coupling portion 251, and since the respective members 251 and 321 are not in a locked state at all, they are inserted by cutting the connecting portion 292. The side coupling portion 291 and the sealing pin member 321 can be easily removed from the front case body 271. The cut-out insertion side coupling portion 291 and the sealing pin member 321 can be easily separated by elastically deforming by pressing the locking claw portion 321c of the sealing pin member 321 with a finger or a tool. The separated sealing pin member 321 does not undergo any deformation or destruction, and the same sealing pin member 321 is used for the next sealing.

  As described above, since the head 321b of the sealing pin member 321 is provided with the identification information for each main controller 131, after the sealing pin member 321 is reused and the sealing process is performed again, the identification information is stored. By checking, it can be confirmed whether the sealing process was performed according to the regular procedure.

  When the sealing of the first sealing portion is released, only the connecting portion 292 on the front case body 271 side is cut (destroyed), and the sealing partner side, that is, the movable base plate 212 in this case is not destroyed. That is, even if the sealing process between the front case body 271 and the movable base plate 212 and the release thereof are repeatedly performed, the movable base plate 212 is not destroyed and no sealing history remains. Therefore, even when the main controller 131 is replaced, the movable base plate 212 (that is, the pedestal device 210) can be reused as it is.

  In the first sealing unit, which of the four sealing locations is to be used is determined in advance, and for example, sealing is performed one by one from the top in FIG. The sealing history remains at the sealing location where the cutting processing (destruction processing) has been performed after sealing, so that it is possible to easily confirm how many times the sealing processing has been performed in the past.

  Next, the configuration of the second sealing portion will be described based on FIG. The second sealing portion can be in a sealed state by coupling the sealing coupling portion 293 provided on the front case body 271 and the sealing coupling portion 315 provided on the back case body 272. The side coupling part 293 "and the latter are paraphrased as" reception side coupling part 315 ", and description is advanced.

  As shown in FIG. 20, a hole portion 293 a (for convenience, referred to as an upper hole portion) penetrating in the up-down direction is formed in the insertion side coupling portion 293 of the front case body 271, and the back case body 272 has a hole 293 a. The receiving side coupling portion 315 is formed with a hole portion 315a coaxially communicating with the upper hole portion 293a (for convenience, referred to as a lower hole portion). The upper hole portion 293a is formed with a large diameter portion for accommodating a head portion of a sealing screw 323 described later and a small diameter portion smaller than the large diameter portion. A female screw portion is formed in the lower hole portion 315a. Then, the sealing screw 323 is screwed into the holes 293a and 315a of the insertion-side coupling portion 293 and the receiving-side coupling portion 315, thereby completing the sealing of the second sealing portion. The sealing screw 323 is composed of a so-called fractured screw having a breakable portion (reduced diameter portion) which is easily fractured at an intermediate portion, and when the screw 323 is screwed in with a tightening tool such as a screwdriver, a torque larger than a predetermined torque is applied. The fractured part is fractured. Due to this breakage, once the sealing screw 323 is screwed into the holes 293a and 315a, it becomes impossible to loosen the screw 323 thereafter.

  In order to release the sealing of the second sealing portion, the connecting portion 294 that connects the insertion-side connecting portion 293 and the front case body 271 is cut with a tool such as a nipper (X1 portion in the figure), and the receiving-side connecting portion. The bottom of 315 is cut with a tool such as a nipper (X2 part in the figure). That is, the vertical cutting process and the horizontal cutting process orthogonal to the vertical cutting process are performed. As a result, the sealing screw 323 can be separated from the case bodies 271, 272 and the sealing of the second sealing portion can be released.

  Next, the configuration of the third sealing portion will be described with reference to FIG. The third sealing portion can be in a sealed state by coupling the sealing coupling portion 301 provided on the front case body 271 and the sealing coupling portion 317 provided on the back case body 272. The description is advanced by paraphrasing the "side coupling portion 301" and the latter as "reception side coupling portion 317".

  As shown in FIG. 21, a hole portion 301 a (for convenience, referred to as an upper hole portion) penetrating in the up-down direction is formed in the insertion side coupling portion 301 of the front case body 271, and the back case body 272 has a hole 301 a. The receiving side coupling portion 317 is formed with a hole portion 317a coaxially communicating with the upper hole portion 301a (for convenience, referred to as a lower hole portion). The upper hole portion 301a is formed with a large diameter portion for accommodating a head portion of a sealing screw 325, which will be described later, and a small diameter portion having a diameter smaller than that. A female screw portion is formed in the lower hole portion 317a. Then, the sealing screw 325 is screwed into the holes 301a and 317a of the insertion-side coupling portion 301 and the receiving-side coupling portion 317, thereby completing the sealing of the third sealing portion. The sealing screw 325 is a so-called one-way screw (also called a one-way screw) that can be screwed in with a tightening tool such as a screwdriver in the tightening direction but cannot be loosened in the loosening direction. Once the screw 325 is screwed into the holes 301a and 317a, the screw 325 cannot be loosened thereafter.

  In order to release the sealing of the third sealing portion, a connecting portion 302 that connects the insertion-side connecting portion 301 and the front case body 271 and a connecting portion 318 that connects the receiving-side connecting portion 317 and the back case body 272. Are cut together with a tool such as a nipper (X3 part in the figure). As a result, the sealing screw 325 can be separated from the case bodies 271 and 272 to unseal the third sealing portion.

  In the above description, it is described that the sealing process is performed on both the second sealing unit and the third sealing unit, but in reality, only one of these sealing units is subjected to the sealing process. For example, when manufacturing the slot machine 10, the second sealing portion is sealed when the main board 273 is housed in the board box (case bodies 271, 272). After that, when the main control device 131 is recovered for inspection or the like, the second sealing portion is opened and the third sealing portion is sealed after the inspection or the like.

  On the other hand, as shown in FIG. 9 and the like, on the left side portion of the main board unit 200, the movable base plate 212 and the front surface of the front case body 271 are surrounded by the movable base plate 212 and the seal attachment surface surrounded by the enclosure frames 331 and 332. A rectangular sealing sticker S is attached so as to extend over the case body 271. When the seal sticker S is peeled off after the sticker S is peeled off, the adhesive is peeled off from the seal label and cannot be stuck again. When the seal S is peeled off, a trace of the sticker sticker S remains. It is possible to confirm whether or not the main controller 131 is removed from the plate 212. In the illustrated state in which the sealing sticker S is attached, the locking hole portion 247 and the through hole 248 formed in the movable base plate 212 are hidden.

  As described above, the seal sticker S is configured so that it cannot be reattached. However, there is a fraudulent act in which another seal member is pasted after the seal sticker S is peeled off. It is considered that one measure is to suppress the act of peeling off the seal S. In view of this, in the present embodiment, as a measure for peeling off the seal, the seal attaching surface composed of the surface of the movable base plate 212 and the surface of the front case body 271 is surrounded by the surrounding frames 331 and 332, and the peripheral portion of the seal attaching surface is curved. It is formed into a shape. Specifically, the seal sticking surface is curved by forming the tapered surface in conformity with the long side portion of the sealing sticker S.

  When the seal sticker S is attached to the seal sticking surface, the peripheral edge of the seal sticker S enters the curved portion of the seal sticking surface, and it becomes difficult to hook the peripheral edge of the seal sticker S with a nail or the like. Therefore, it is possible to obtain the effect of preventing the seal S from being peeled off illegally.

  As shown in FIG. 22, when the main control device 131 is mounted on the pedestal device 210, the key mounting metal fitting 261 provided on the movable base plate 212 and the key mounting metal fitting 316 provided on the back case body 272 of the main control device 131. The key members K1 such as a padlock are attached through the key insertion portions 261a and 316a of the key attachment fittings 261 and 316, respectively. Further, in the state where the fixed base plate 211 and the movable base plate 212 are overlapped with each other, the key fitting 219 provided on the fixed base plate 211 and the key fitting 305 provided on the front case body 271 face each other, A key member K2 such as a padlock is attached through the key insertion portions 219a and 305a of the respective key attachment fittings 219 and 305. The unlocking keys of the key members K1 and K2 are managed by a game hall manager or the like.

  With such a configuration, the movable base plate 212 cannot be rotated with respect to the fixed base plate 211 unless the key member K2 is removed. Further, even if the key member K2 is removed, the main controller 131 cannot be removed from the movable base plate 212 unless the key member K1 is removed. Therefore, only the owner of the unlock key properly managed can remove the main controller 131.

  Since each of the above-mentioned sealing parts is originally configured to be cut (destroyed) and its main purpose is to leave an opening history, it is possible to prevent fraudulent acts such as taking away (stealing) the main control device 131. Although the effect cannot be exerted, the above-described configuration in which the key members K1 and K2 are attached can exert a deterrent effect on the removal of the main control device 131 (which can be a countermeasure against theft of the main control device 131).

  The tip ends of the key attachment fittings 219 and 305 are provided so as to be inclined so as to escape from the main control device 131. As a result, even if the key member K2 is attached to the side of the front case body 271, the key member K2 can be attached without being obstructed by the front case body 271 or the like.

  Next, a procedure for removing the main control device 131 from the pedestal device 210 with the main board unit 200 attached to the back plate 11c of the housing 11 will be described with reference to FIG. 23A shows a state in which the movable base plate 212 is superposed on the fixed base plate 211 (that is, a normal use state), and FIG. 23B shows the movable base plate 211 with respect to the fixed base plate 211. 212 shows a state in which the movable base plate 212 is rotated toward the front side, and (c) shows a state in which the main controller 131 is slid from the movable base plate 212 in the rotated state. In FIG. 23, the lower side is the front of the slot machine and the upper side is the rear of the slot machine.

  In the state of (a), the fixed base plate 211 and the movable base plate 212 overlap each other, and the locking claw portion 218 of the fixed base plate 211 has the main controller 131 (actually, the front case body 271). Is locked to the upper surface of. Although illustration is omitted for convenience, the key members K1 and K2 are attached to the main board unit 200 as described above, and the movable base plate 212 is not rotatable with respect to the fixed base plate 211. At this time, the surface portion of the main controller 131 faces the front side of the slot machine 10, and the surface of the main board, that is, the mounting surface of the IC chip or the like is visually recognized from the front.

  Further, when the movable base plate 212 shown in (b) is rotated, the key member (at least the key member K2 in FIG. 22) is removed, and the locking claw portion 218 of the fixed base plate 211 is unlocked. In this state, the movable base plate 212 is rotated with respect to the fixed base plate 211 as illustrated. At this time, the movable base plate 212 is rotated about 90 degrees at the maximum with the support pin 217 as the rotation center, and the rotation front end side of the main control device 131 is pulled toward the front side together with the movable base plate 212. In such a state, the back side of the main control device 131 (that is, the back side of the main board 273) can be visually recognized, and it is possible to confirm whether or not there are any abnormalities or irregularities in various electronic components, electric wiring, and the like.

  When the movable base plate 212 and the main control device 131 are rotated with respect to the fixed base plate 211 as shown in (b), the main control device 131 is viewed from an oblique lateral side from a state viewed from the front side. Transition to the state. Therefore, even if the information is difficult to be seen from the front of the main control device 131, that is, the information attached to the upright surface portion of the main substrate 273 which is substantially perpendicular to the substrate surface, the movable base plate 212 can be easily visually recognized. Can be For example, in the vertical IC chip 274 mounted on the main board 273, information such as a manufacturer and a product number printed on the side surface of the chip can be easily visually recognized.

  Incidentally, in the actual configuration of the slot machine 10, as shown in FIG. 5 and the like, the front space of the main control device 131 is open, and there is no hindrance to the forward rotation operation of the movable base plate 212. It never happens. Even if a device or mechanism projecting to the rear of the slot machine is provided on the back surface of the front door 12, the front space of the main controller 131 is opened as the front door 12 is opened, and the movable base plate 212 is also rotated. Does not cause any problems.

  Further, when the main control device 131 shown in FIG. 23C is slid, the key member (key member K1 in FIG. 22) is removed, and the first seal portion (the movable base plate 212 and the front case body 271 is sealed). ) Is opened. Furthermore, the locking of the locking claw portion 295 provided at the left end of the front case body 271 and the screw fixing at the screw hole portion 296 are released. Then, in this state, main controller 131 slides on movable base plate 212. As a result, it becomes possible to disengage the main control device 131 from the pivoting front end side of the movable base plate 212 (the board mounting opening 245 in FIG. 12).

  Next, the electrical configuration of the slot machine 10 will be described based on the block diagram of FIG.

  The main controller 131 is equipped with a microcomputer centered on a CPU 151 which is an arithmetic processing unit. In addition to the power supply device 161 provided inside the power supply box 121, a clock circuit 154 that outputs a rectangular wave of a predetermined frequency, an input / output port 155, and the like are connected to the CPU 151 via an internal bus. The main controller 131 functions as a main board built in the slot machine 10.

  On the input side of the main controller 131, a start detection sensor 71a for detecting the operation of the start lever 71, stop detection sensors 72a, 73a, 74a for individually detecting the operations of the stop switches 72, 73, 74, and a medal insertion slot. Insertion medal detection sensor 75a for detecting medals inserted from 75, credit insertion detection sensors 77a, 78a, 79a for individually detecting operation of each credit insertion switch 77, 78, 79, and switching for detecting operation of changeover switch 80 A detection sensor 80a, a reel index sensor 55 that individually detects the rotation position (origin position) of each reel 42, a payout detection sensor 91a that detects medals paid out from the hopper device 91, and a reset detection sensor that detects operation of the reset switch 123. 123a, set in the setting key insertion hole 124 Chromatography are connected various sensors such as setting the key detection sensor 124a for detecting that it has been inserted, the signals from these various sensors are outputted to the CPU151 through the input and output ports 155.

  The inserted medal detection sensor 75a is actually composed of a plurality of sensors. That is, the storage passage 81 from the medal insertion slot 75 to the hopper device 91 is configured so that the medals can pass in one row. Further, the storage passage 81 is provided with the first sensor, and the second sensor and the third sensor are close to each other on the downstream side, which is separated from the medal by at least the width of the medal (to the extent that the same medal is simultaneously detected at least temporarily) Are provided in close proximity to each other, and the inserted medal detection sensor 75a is configured by these first to third sensors. The main control device 131 monitors the time from the first sensor to the second sensor, and if the elapsed time exceeds a predetermined time, it is considered that there is a medal clogging or fraud and an error occurs. When an error occurs, error notification is given and the operation by the player until the error is canceled is invalidated. The main controller 131 also monitors the order in which the second sensor and the third sensor are turned on and off. Both the second and third sensors are off, only the second sensor is on, and both the second and third sensors are on. It is determined that the medals have been normally taken in only when the sequence is such that only the third sensor is turned on and both the second and third sensors are turned off, and when the time for switching to each on / off switching is within a predetermined time. However, in other cases, it is an error. This is done in order to prevent medals from clogging the storage passage 81 and fraud in which the medals are reciprocally moved in the vicinity of the inserted-medal detection sensor 75a and are mistakenly recognized as inserting medals.

  A power failure monitoring circuit 161b provided in the power supply device 161 is connected to the input side of the main control device 131 via the input / output port 155. On the power supply board 161, a power supply unit 161a that supplies drive power to each electronic device of the slot machine 10 including the main controller 131, the above-described power failure monitoring circuit 161b, and the like are mounted.

  The power failure monitoring circuit 161b is for monitoring the power cut-off state and generating a power failure signal when the power is cut off by the power switch 122 as well as when the power is cut off. Therefore, the power failure monitoring circuit 161b monitors the stabilized drive voltage of DC 12V output from the power supply unit 161a in this example, and determines that the power supply is cut off when the drive voltage drops to less than 10V, for example. Is configured to output a power failure signal. The power failure signal is supplied to each of the CPU 151 and the input / output port 155, and the CPU 151 recognizes the power failure signal to execute a power failure process described later.

  Even if the output voltage drops to less than 22 volts, the power supply section 161a outputs a stabilized voltage of 5 volts that is used as a drive voltage in a control system such as the main controller 131. As the time during which the stabilized voltage is output, a time sufficient for the main controller 131 to execute the power failure process is secured.

  On the output side of the main controller 131, in order to rotate the activated line display sections 32, 33, 34, the remaining number display section 35, the game number display section 36, the acquired number display section 37, and the reels 42L, 42M, 42R. Of the stepping motors 61 (61L, 61M, 61R), the medal passage switching solenoid 83 provided in the selector 84, the hopper device 91, the display control device 111, an external centralized terminal board 171 capable of transmitting information to a hall management device (not shown), etc. Etc. are connected via the input / output port 155.

  The display control device 111 is a control device for driving the upper lamp 13, the speaker 14, and the auxiliary display unit 15, and includes a substrate in which a CPU, a ROM, a RAM, and the like for driving these are integrated. Then, after receiving a signal from the main control device 131, the display control device 111 independently drives and controls the upper lamp 13, the speaker 14, and the auxiliary display unit 15. Therefore, the display control device 111 is a sub-base for executing auxiliary control in relation to the main control device 131 which is a main base for centrally managing the game. That is, by providing a sub-board for voices, lamps, and displays related to indirect games, the burden on the main board is reduced. The display control device 111 may control the various display units 32 to 37.

  The above-mentioned CPU 151 has a ROM 152 in which various control programs executed by the CPU 151 and fixed value data are stored, and an operation of temporarily storing various data in executing the control programs stored in the ROM 152. In addition to the RAM 153 for securing the area, although not shown, as is well known, various processing circuits necessary for the slot machine 10, such as an interrupt circuit, a timer circuit, a data transmission / reception circuit, and a credit counter for counting the number of credits. Various counters such as are built in. The ROM 152 and the RAM 153 constitute a main memory as a storage unit, and programs for executing the processes shown in the various flowcharts shown in FIG. 25 and subsequent figures are stored in the ROM 152 described above as a part of the control program.

  The RAM 153 has a configuration in which a backup voltage is supplied from the power supply device 161 provided in the power supply box 121 to retain data (backup) even after the power of the slot machine 10 is shut off. In addition to a memory and an area for temporarily storing various data and the like, a backup area is provided.

  When the power is cut off due to the occurrence of a power failure or the like, the backup area has a stack pointer, a value of each register, I / O, etc. when the power is cut off (including power cutoff by operating the power switch 122. This is an area for storing the data, and when the power outage is resolved (including powering on by operating the power switch 122. The same applies hereinafter), the state of the slot machine 10 is based on the information in the backup area before power shutdown. It is possible to return to the state. Writing to the backup area is executed when the power is cut off by the power failure process (see FIG. 27), and restoration of each value written in the backup area is executed in the main process when the power is turned on (see FIG. 28). The NMI terminal (non-maskable interrupt terminal) of the CPU 151 is configured such that a power failure signal is input from the power failure monitoring circuit 161b when the power is cut off due to the occurrence of a power failure, etc. The NMI interrupt process as the flag generation process is immediately executed.

  Next, each control process executed by the CPU 151 in the main controller 131 will be described with reference to the flowcharts of FIGS. 25 to 34. The processing of the CPU 151 is broadly divided into a main processing that is started when the power is turned on, a timer interrupt processing that is started regularly (at a cycle of 1.49 msec in this embodiment), and an NMI terminal (non-maskable terminal). The NMI interrupt processing started by the input of the power failure signal is described. For convenience of description, the NMI interrupt processing and the timer interrupt processing will be described first, and then the main processing will be described.

  FIG. 25 is a flowchart showing an example of NMI interrupt processing. When the power is cut off due to the occurrence of a power failure or the like, the power failure monitoring circuit 161b of the power supply device 161 generates a power failure signal and outputs it to the main controller 131. The main controller 131 which has received the power failure signal via the NMI terminal executes NMI interrupt processing.

  In the NMI interrupt process, first, in step S101, the data of the use register provided in the CPU 151 is saved in the backup area provided in the RAM 153. Succeedingly, in a step S102, a power failure flag is set in a power failure flag storage area provided in the RAM 153. After that, the data saved in the backup area of the RAM 153 in step S103 is restored to the register used by the CPU 151 again. The NMI interrupt process is completed by this restoration process. If the power failure flag can be set without destroying the data of the register used by the CPU 151, the save and restore processing to the backup area can be omitted.

  FIG. 26 is a flowchart of a timer interrupt process that is periodically executed by the main control device 131, and the CPU 151 of the main control device 131 generates a timer interrupt every 1.49 msec, for example.

  First, in the register saving process shown in step S201, the values of all the registers in the CPU 151 used in the normal process described later are saved in the backup area of the RAM 153. In step S202, it is confirmed whether or not the power failure flag is set, and when the power failure flag is set, the process proceeds to step S203 to execute the power failure process.

  Here, the power failure process will be described with reference to FIG. This power failure process is performed immediately after the register saving process of the timer interrupt process, so that it can be executed without interrupting other interrupt processes. Therefore, the process at the time of power failure is not executed by interrupting each process, such as during the process of transmitting various commands or the process of reading the state of the switch (ON / OFF). It is no longer necessary to create a program for processing during a power failure that also considers This simplifies the processing program for power failure processing and reduces the program capacity. This also applies to a processing program for power recovery processing, which will be described later.

  In step S301, it is determined whether command transmission has been completed. If the transmission has not ended, the process returns to the original process of FIG. In this way, it is determined whether command transmission is completed at the initial stage of power failure processing, priority is given to transmission processing when transmission is not completed, and power failure processing is executed after unit command transmission processing is completed. By doing so, it is not necessary to construct a power failure processing program in consideration of execution of power failure processing during command transmission. As a result, there is an actual advantage that the capacity of the ROM 152 can be reduced by simplifying the power failure process program.

  If step S301 is YES, that is, if the command transmission is completed, the process proceeds to step S302, and the value of the stack pointer of the CPU 151 is stored in the backup area in the RAM 153. After that, in step S303, the RAM determination value, which will be described later, is cleared as the stop processing, the output state of the output port of the input / output port 155 is cleared, and all the actuators (not shown) are turned off. In step S304, the RAM judgment value is calculated and stored in the backup area. The RAM judgment value is specifically the two's complement of the checksum value in the work area address of the RAM 153. By storing the RAM judgment value in the backup area, the checksum of the RAM 153 becomes zero. By setting the checksum of the RAM 153 to 0, subsequent RAM access is prohibited in step S305. After that, it enters an infinite loop in preparation for the power being completely cut off and processing cannot be executed.

  The power supply unit 161a of the power supply device 161 holds the output of the stabilized voltage (5 volts) used as the drive voltage of the control system for a sufficient time to execute the NMI interrupt processing and the power failure processing described above. Is configured to. In this embodiment, the drive voltage is continuously output for 30 msec.

  Returning to the explanation of the timer interrupt process, if the power failure flag is not set in step S202, various processes after step S204 are performed.

  That is, in step S204, the watchdog timer is cleared to initialize the value of the watchdog timer for monitoring the occurrence of malfunction. In step S205, an interrupt end declaration process for issuing an interrupt permission to the CPU 151 itself is performed. In step S206, stepping motor control processing for driving the stepping motors 61L to 61R, which are the respective drum driving motors, is performed in order to rotate the reels 42L, 42M, and 42R. In step S207, sensor monitoring processing for monitoring the states of various sensors (see FIG. 24) connected to the input / output port 155 is performed. In step S208, timer calculation processing for subtracting the value of each counter or timer is performed. In step S209, counter processing for counting the bet number of medals and the number of payouts is performed.

  In step S210, command output processing for transmitting a command or the like to the display control device 111 is performed. In step S211, segment data setting processing for setting segment data displayed on the remaining number display section 35, the game number display section 36, and the acquired number display section 37 is performed. In step S212, the segment data display process of supplying the segment data set in the segment data setting process to each of the display units 35 to 37 and displaying the corresponding numbers and symbols is performed. In step S213, port output processing for outputting the data corresponding to the I / O device from the input / output port 155 is performed. In step S214, the value of each register saved in the backup area in step S201 is restored to the corresponding register in CPU 151. After that, in step S215, an interrupt permission process for permitting the next timer interrupt is performed, and this series of timer interrupt processes ends.

  FIG. 28 is a flowchart showing main processing in main controller 131 executed after power is turned on. The main process is executed when the power is turned on by recovery from a power failure or turning on the power switch 122.

  First, in step S401, as the initialization process, the value of the stack pointer is set in the CPU 151, and the interrupt mode for permitting the interrupt process is set, and then various settings for the register group in the CPU 151, the I / O device, and the like. And so on.

  Upon completion of these initialization processes, it is then determined in step S402 whether or not the reset switch 123 has been turned on. When the reset switch 123 is turned on, the process proceeds to step S403, and all the data stored in the RAM 153 is cleared as a RAM clearing process.

  After confirming that the reset switch is not operated in step S402 or performing the RAM clear processing in step S403, it is determined in step S404 whether the setting key is inserted in the setting key insertion hole 124. To do. If the setting key is inserted, the process proceeds to step S405 to perform the setting change process. As the setting change processing, first, all the data stored in the RAM 153 is cleared. Then, after determining which setting state has been selected among the preset six-stage setting states (“setting 1” to “setting 6”), internal processing is executed according to the selected setting state. .

  In step S406, it is confirmed whether or not the power failure flag is set. If the power failure flag is not set, that is, if the data in the RAM 153 has been cleared in the previous step S403 or step S405, the process proceeds to normal processing in step S407, which will be described later, and this processing ends.

  When the power failure flag is set in step S406, the power recovery process shown in step S408 and subsequent steps is performed. The fact that the power failure flag is set means that the subroutine processing such as the RAM clearing processing in step S403 and the setting changing processing in step S405 has not been executed at all. Therefore, the data in the RAM 153 has not been rewritten at all, and it is necessary to confirm whether or not the data in the RAM 153 is normal in the power recovery process.

  Therefore, first, in step S408, it is confirmed whether or not the RAM determination value is normal. Specifically, the checksum of the RAM 153 is checked, and it is confirmed whether the value is normal, that is, whether the checksum including the RAM judgment value is 0. When the value of the checksum including the RAM judgment value is 0, it is judged that the data in the RAM 153 is normal.

  If the RAM determination value is abnormal in step S408, that is, if the checksum value is not 0, it is highly possible that the data in the RAM 153 has been destroyed. Therefore, in such a case, error display processing is performed in step S409. As the error display processing, first, interrupt processing is prohibited, and all output ports in the input / output port 155 are cleared to control all the actuators connected to the input / output port 155 to the off state. After that, an error message is displayed to inform the hall manager of the occurrence of an error, and the state is maintained until the reset switch 123 is turned on.

  When it is determined in step S408 that the RAM determination value is normal, the process proceeds to step S410, the stack pointer value stored in the backup area is written in the stack pointer of the CPU 151, and the stack state before the power is cut off. Restore the condition. Next, in step S411, a power recovery command that notifies execution of power recovery processing is transmitted to the display control device 111. After that, in step S412, the game state is stopped and automatic settlement setting storage processing is performed, and in step S413, various sensors such as the start detection sensor 71a are initialized. After the above processing is completed, the power failure flag is reset in step S414, and the process returns to the address before the power shutdown. Specifically, the process returns to the timer interrupt process described above, and the watchdog timer clear process (step S204) is executed.

  Next, normal processing for performing main control relating to the game will be described with reference to the flowchart of FIG.

  First, in step S501, it is determined whether or not a medal has been bet. When the medal is bet, it is subsequently determined in step S502 whether the start lever 71 has been operated. If YES in both steps S501 and S502, the lottery process in step S503, the reel control process in step S504, the medal payout process in step S505, and the special game state process in step S506 are sequentially executed, and the process returns to step S501. On the other hand, if no medals have been bet in step S501 or the start lever 71 has not been operated in step S502, the process returns to step S501.

  Next, the lottery process of step S503 will be described based on the flowchart of FIG.

  In step S601, a random number table for determining a win / fail is selected based on the current setting state of the slot machine 10, the number of medals bet, the small winning probability, and the like. Here, the setting state of the slot machine 10 is one of “setting 1” to “setting 6” set by using a setting key (not shown), and when “setting 1”, a random number with the lowest winning probability of the winning combination. A table is selected, and a random number table with the highest winning probability of a winning combination is selected when "Setting 6". Further, the number of medals bet is any one of 1 to 3, and a random number table is selected such that the winning probability of the winning combination becomes higher as the number of bets becomes larger. For example, the winning probability of a winning combination when three bets are placed is three times higher than the winning probability of a winning combination when one bet is placed. Furthermore, there are two types of small winning probability, high and low, and a random number table with a high small winning probability is selected when the current payout rate is below a predetermined expected value, and a small random table when it is above a predetermined expected value. A random number table with a low winning probability is selected.

  In step S602, the random number table thus selected is illuminated with the random numbers latched by the random number counter when the start lever 71 is operated, and a winning combination is performed. Then, in step S603, it is determined whether or not any winning combination has been won. If no winning combination has been won, this process is ended. If any winning combination has been won, the process proceeds to step S604, and a winning flag corresponding to the winning combination is set, and an effective line to which the symbols are to be aligned is determined. Succeedingly, in a step S605, a sliding table for reel stop control is determined and stored in the sliding table storage area of the RAM 153. Here, the sliding table is a predetermined symbol to be stopped when the symbol on the prescribed effective line at the timing when the stop switches 72 to 74 are pressed and the symbol to be stopped on the activated line are different. It is a table that determines how much the reel slides so as to stop on the effective line of.

  Next, the reel control process of step S504 will be described based on the flowchart of FIG.

  In the reel control process, first, a weight process is performed in step S701. This weight process is a process of waiting for a predetermined time (for example, 4.1 seconds) from the time when the reel starts to be rotated in the previous game without starting the rotation of the reel in the current game. Therefore, even if the player bets a medal and operates the start lever 71, the reels 42L, 42M, 42R may not immediately rotate. Following the weight process, the reel rotation process of step S702 is performed to rotate each reel 42L, 42M, 42R. After that, the process proceeds to step S703, and it is determined whether or not any one of the stop switches 72 to 74 is pressed to generate a reel stop command. If the stop command is not issued, the process proceeds to step S704, and it is determined whether or not a predetermined maximum rotation time (for example, 40 seconds) of each reel 42L, 42M, 42R has passed. If the maximum rotation time has not elapsed, the process returns to step S703, and if the maximum rotation time has elapsed, the process proceeds to step S705 to perform a forced stop process for forcibly stopping all the spinning reels.

  On the other hand, if any of the stop switches 72 to 74 is pressed to generate a stop command in step S703, the process proceeds to step S706 to perform reel stop processing. In this reel stop processing, the reel corresponding to the pressed stop switch is stopped, but the winning combination is won in the lottery of the winning combination, and when the winning flag is set, it is stored in the sliding table storage area of the RAM 153. By referring to the sliding table, the winning combination is controlled as much as possible to be aligned on a predetermined effective line. For example, if you win the role that "Watermelon" symbols are lined up on the lower line, and if the stop switch is pressed at the timing when the "Watermelon" symbols are stopped on the upper line, the symbol 2 will be stopped on the lower line. Slide the reel by one amount. However, since the range that can be slid is predetermined (for example, up to four symbols), the "watermelon" symbol may not stop on the lower line depending on the timing of pressing the stop switch. Even in the forced stop process of step S705, if the winning flag is set, the same process is performed.

  Succeedingly, in a step S707, it is determined whether or not the stop command of this time is the first stop command, that is, whether or not the stop switch is pressed while all three reels are rotating. In the case of the first stop command, the process proceeds to step S708, and the sliding table changing process is performed. In this sliding table changing process, for example, it is determined whether or not a combination of winning combinations occurs when trying to align a winning combination on the activated line, and when a combination of winning combinations does not occur, the process directly proceeds to the next step, When a combination of winning combinations occurs, the winning effective line is changed to another effective line, the sliding table is changed to match the changed effective line, and then the process proceeds to the next step. Here, the combination of the winning combination means that a plurality of winning combinations occur at the same time, for example, when a "cherry" symbol appears on the lower line on the left reel when trying to align the "watermelon" symbols on the upper line. Say the case. The sliding table changing process may be performed at times other than avoiding the combination of winning combinations.

  On the other hand, if the current stop command is not the first stop command in step S707, the process proceeds to step S709 to determine whether the second stop command is received, that is, one reel of the three reels is stopped and two reels are rotating. Sometimes it is determined whether or not the stop switch has been pressed. When it is the second stop command, the process proceeds to step S710 to perform stop eye determination processing. In this stop eye determination process, when two reels are stopped, it is determined whether or not the two reels are aligned with a bonus symbol such as a "7" symbol, and when they are not aligned, the process directly proceeds to the next step and is aligned. When the speaker 14 is present, a sound effect is generated from the speaker 14 and then the process proceeds to the next step. In the stop eye determination process, it may be determined whether or not another condition other than the two bonus symbols is established, or an effect using the auxiliary display unit 15 may be performed in addition to the sound effect.

  Then, after the forced stop process of step S705, after the sliding table change process of step S708, when the current stop command is not the second stop command in step S709, or the stop eye determination process of step S710 is performed. After that, in step S711, it is determined whether or not all the rotations of the left, center, and right reels 42L, 42M, 42R have stopped. If NO in step S711, the process returns to step S703, and if YES in step S712, the payout determination process is performed in step S712, and then the present process ends. In the payout determination process, it is determined whether or not the winning combination is lined up on the activated line. When the winning combination is not lined up on the activated line, 0 is set in the expected payout amount storage area of the RAM 153, and the winning combination is lined up on the activated line. If it is, it is determined whether or not the winning combination matches the winning combination. If the winning combination does not match, an error is displayed by the upper lamp 13 and the like, and 0 is set in the planned payout amount storage area. If they match, the number of payouts corresponding to the winning combination arranged in the planned payout amount storage area is set.

  Next, the medal payout process of step S505 will be described with reference to the flowchart of FIG.

  In the medal payout process, first, it is determined whether or not the payout number counted by the payout number counter in step S801 and the planned payout number stored in the planned payout amount storage area match. When the number of payouts and the expected number of payouts do not match, it is determined in step S802 whether or not the game is being played in the credit mode. In the credit mode, it is determined in step S803 whether or not the count value of the credit counter has reached the upper limit (the number of stored medals is 50). When the upper limit is not reached, the count value of the credit counter and the payout amount are each incremented by 1 in step S804. As a result, the numbers in the remaining number display section 35 and the acquired number display section 37 are each incremented by one.

  On the other hand, when the game is being played in the direct mode, or when the count value of the credit counter has reached the upper limit, the medal payout rotating plate is driven in step S805, and medals are ejected from the hopper device 91 to the medal ejection port. The coins are paid out to the medal tray 18 via 17. At this time, in step S806, the payout amount is incremented by 1 in accordance with the medal detection signal of the payout detection sensor 91a attached to the hopper device 91. As a result, the number in the acquired number display section 37 is incremented by 1. Then, after the payout amount is incremented by 1 in step S804 or step S806, the process returns to step S801 again. When the number of payouts and the expected number of payouts match in step S801, the medal payout rotating plate of the hopper device 91 is stopped in step S807, and this processing ends. The payout amount / acquired number display portion 37 is reset when the start lever 71 is operated next time.

  Next, the special game state processing of step S506 will be described based on the flowchart of FIG.

  Prior to the description of the special game state processing, the bonus game will be described. The regular bonus (hereinafter referred to as “RB”) game is composed of 12 JAC games. The JAC game is a game in which only one bet is allowed, and the probability that the JAC symbols (here, the replay symbols are substituted) are aligned on the activated line, that is, the probability that the JAC symbols are established is very high. When the JAC symbol is established in the JAC game, the maximum number (15 here) of medals are paid out. When the JAC symbol is established eight times, the RB game ends even before the JAC game reaches 12 times. On the other hand, the big bonus (hereinafter referred to as “BB”) game is composed of 30 small winning games and 3 JAC ins. A small role game is a game in which a small role is won with a high probability (the "bell" symbols and the like are lined up on the activated line), and JAC in means entering 12 JAC games. When the JAC symbols are lined up on the activated line, the JAC in is established. The JAC game is similar to the RB game. When the JAC game with the third JAC in ends, the BB game ends even before the small win game reaches 30 times, and when the small win game ends 30 times, the JAC in reaches 3 times. Even if there is, the BB game ends.

  Now, in the special game state processing, first, in step S901, it is determined whether or not the game state is a bonus game. When the bonus game is not in progress, the process proceeds to step S902, and bonus symbol determination processing is performed.

  In this bonus symbol determination processing, as shown in FIG. 34, first, in step S1001, it is determined whether or not the RB winning flag is set, and when it is set, the process proceeds to step S1002, and the RB symbol is currently on the activated line. It is determined whether or not (for example, "BAR" symbols) are aligned, and if the RB symbols are not aligned, the present process is ended. On the other hand, when the RB symbols are aligned on the activated line this time, the RB winning flag is reset and the RB setting flag is set in step S1003 to make the RB game as one type of bonus game, and the RB game initial setting process shown in FIG. Is executed to end the present process. When the RB winning flag is not set in step S1001, it is determined whether or not the BB winning flag is set in step S1004, and when it is not set, this processing is ended as it is. When the BB winning flag is set, the process proceeds to step S1005, and it is determined whether or not BB symbols (for example, symbol "7") are aligned on the activated line this time. If the BB symbols are not aligned, this process is ended as it is. . On the other hand, when the BB symbols are aligned on the activated line this time, the BB winning flag is reset and the BB setting flag is set in step S1006 to make a BB game which is one of the bonus games, and the BB game initial setting process shown in FIG. 36 is performed. This is executed and this process is terminated.

  35 and 36, the remaining small winning combination game counter represents the number of remaining small winning combination games (also referred to as the remaining small winning combination game), and the remaining JAC in counter represents the remaining number of JAC ins (the number of remaining JAC ins. Also, the remaining JAC establishment counter represents the remaining number of times that the JAC symbol can be established (also referred to as remaining JAC establishment number), and the remaining JAC game counter represents the remaining number of JAC games (also referred to as remaining JAC game number). Represent The number of remaining small winning games, the number of remaining JAC ins, the number of remaining JACs established, and the number of remaining JAC games are appropriately displayed on the game number display unit 36. By the way, when a small win or replay win is set by winning a small win or replay in a lottery of a winning role, if the small win or replay pattern is not aligned on the activated line in the game, these win flags Will be reset, but if the RB winning flag or the BB winning flag is set by winning the RB or BB in the lottery of the role, even if the RB symbol or the BB symbol cannot be aligned on the activated line in the game, these The winning flag of will be carried over to the next time. In the lottery process in the next game in which the BB or RB winning flag is carried over, the lottery regarding whether or not the small winning combination or the replay can be won is performed, but the lottery regarding the BB or RB is not performed. Further, when the small win or replay is won while the BB or RB win flag is carried over, the sliding table is stored so that the small win or replay is preferentially arranged.

  Now, returning to FIG. 33, when the game state is the bonus game in step S901, it is determined in step S903 whether or not the bonus game is the JAC game. When it is not the JAC game, it means that the small winning combination game of the BB game is being executed, and therefore, the processing proceeds to step S904, and it is determined whether or not the JAC symbols are aligned on the activated line. When the JAC symbols are aligned on the activated line, the JAC game is started in step S905, the JAC game initial setting process in the BB game of FIG. 36B is performed, and this process is ended. On the other hand, when the JAC symbols are not aligned on the activated line in step S904, one small winning game has been exhausted, so the number of remaining small winning games is decremented by 1 in step S906, and in step S907. It is determined whether or not the number of remaining small winning games has become zero. When the number of remaining small winning games is not 0, this process is ended, and when it is 0, the process proceeds to step S908, and special game state end process of appropriately resetting various setting flags, BB setting flags, various counters, etc. and performing ending processing. Then, the present process ends.

  When the gaming state is the JAC game in step S903, it is determined whether or not the JAC symbols are aligned on the activated line in step S909. When the JAC symbols are aligned on the activated line, the remaining JAC establishment number is determined in step S910. Decrement by 1. After that, or when the JAC symbols are not aligned on the activated line in step S909, it means that one JAC game has been consumed, so the remaining JAC game number is decremented by 1 in step S911. Succeedingly, in a step S912, it is determined whether or not either the number of remaining JACs established or the number of remaining JAC games becomes 0, and when neither is 0, that is, the JAC symbol has not been formed 8 times yet. If the JAC game has not been digested 12 times, this process is terminated. On the other hand, when either one is 0, that is, when the JAC symbol is established 8 times or when the JAC game is consumed 12 times, it means that the JAC in has been exhausted once, and therefore the remaining JAC in is performed in step S913. The number of times is decremented by 1, and it is determined in the subsequent step S914 whether or not the number of remaining JAC ins is 0. When it is 0, the special game state end process of step S908 described above is performed, and this process ends. By the way, when the bonus game is the RB bonus, the initial number of remaining JAC ins is 1 (see FIG. 35), so it becomes 0 in step S913, and an affirmative determination is always made in step S914, and the special game of step S908. The RB setting flag is reset in the state end processing.

  On the other hand, when the number of remaining JAC ins is not zero in step S914, that is, when the JAC ins have not been exhausted three times in the BB game, the JAC game end process of resetting the JAC game setting flag is performed in step S915, and then the current JAC Since one small winning game has been consumed when the game is played, the number of remaining small winning games is decremented by 1 in step S906, and subsequently it is determined in step S907 whether or not the number of remaining small winning games has become zero. When it is determined that the number of remaining small winning games is 0, the special game state ending process of step S908 described above is performed, and this process is finished. On the other hand, when the number of remaining small winning combination games is not 0, the number of small winning games in the BB bonus has not reached 30 times and the JAC in has not reached 3 times, so this processing ends.

  According to the present embodiment described in detail above, the following excellent effects are exhibited.

  In the main board unit 200 attached to the back plate 11c of the housing 11, the movable base plate 212 having the main controller 131 mounted thereon is rotatable with respect to the fixed base plate 211. The back surface (back surface of the main board) of the control device 131 is opened. Therefore, it is possible to confirm whether there are any abnormalities or irregularities in the various electronic components or electric wiring on the back surface side. When the movable base plate 212 is rotated, the side surface information of the vertical element (IC chip 274) mounted on the main board 273 can be easily read by tilting the board surface of the main control device 131. It is possible to confirm that the device is a genuine product. As a result, it is possible to confirm that the main control device 131 is not performing an illegal act, so that the main control device 131 can be properly managed.

  When an electronic component other than the vertical element is mounted parallel to the surface of the board, another unauthorized electronic component (illegal IC) should be attached to the lower side of the electronic component (that is, between the electronic component and the substrate). However, since the movable base plate 212 on which the main control device 131 is mounted can be rotated with respect to the fixed base plate 211 as described above, it is possible to implement measures against such illegal acts. In other words, it is difficult to find an illegal IC hidden under a legitimate electronic component only by looking at the front side of the main controller 131 from the front, but by rotating the movable base plate 212, the illegal IC can be detected. Easy to find.

  As an effect of attaching the main board unit 200 to the back plate 11c of the inner peripheral surface of the housing 11, it is difficult to remove the main control device 131 illegally, and the main control device 131 is still attached to the main control device 131. It is difficult to carry out unauthorized work on the main controller 131, and since the distance between the main control device 131 and the front open part of the housing 11 becomes long, an unauthorized signal line is connected to the main control device 131 via the front open part of the housing 11. It is difficult for fraudulent activity, the main control device 131 is visible in the front when the front door 12 is released, and it is easy to find fraud on the substrate surface. Since the lateral width is larger than that of the side plates 11d and 11e, even a relatively large control device can be mounted. And so on.

  By sliding the main controller 131 on the movable base plate 212 in a state where the movable base plate 212 is rotated, the main controller 131 can be attached and detached from the rotating front end side of the movable base plate 212. Therefore, main controller 131 can be easily attached or detached in a state in which the rotating front end of movable base plate 212 is pulled toward the front side. Therefore, it is possible to improve workability during inspection and replacement of the main control device 131.

  Since the fixed base plate 211 is fastened from the outside of the case with the back plate 11c of the case 11 using the screws 233, for example, when a large number of slot machines 10 are installed in the game hall, the fixed base plate 211 is installed. Is extremely difficult to remove, and as a result, unauthorized removal of the main control device 131 can be suppressed. Accordingly, it is possible to suppress an illegal act in which not only the main control device 131 but also the pedestal device 210 are collectively taken away (stealed).

  It should be noted that the present invention is not limited to the contents described in the above embodiment, and may be implemented as follows, for example.

  (A) In the above-described embodiment, the main board unit 200 is attached to the back plate 11c of the housing 11, but instead of this, the main board unit 200 is located on either the left or right side plate 11d, 11e of the housing 11. It may be configured to be attached to. Even if it is attached to either the left or right side plate 11d or 11e of the housing 11, the main control device 131 is brought to the front side (that is, the slot machine) by making the rotary base plate 112 rotatable with respect to the fixed base plate 211. It becomes possible to draw it to the front of 10), and there exists an outstanding effect as above-mentioned.

  (B) In the above embodiment, the fixed base plate 211 and the movable base plate 212 are rotationally connected by using the support pin 217 press-fitted into the shaft hole, but this configuration is changed. For example, a configuration may be adopted in which a support column is integrally formed with either the fixed base plate 211 or the movable base plate 212, and the fixed base plate 211 and the movable base plate 212 are pivotally connected by this support column. Any configuration can be applied as long as the base plates 211 and 212 are rotatable and cannot be separated (cannot be disconnected).

  (C) In the above-described embodiment, the fixed base plate 211 and the movable base plate 212 in the main board unit 200 are set to have substantially the same size according to the main controller 131 (board box), but this configuration is changed. For example, the movable base plate 212 is made smaller than the main controller 131 (board box). Specifically, a configuration in which the length of the movable base plate 212 in the longitudinal direction is set to ⅔, ½, ⅓ of the length of the main control device 131 can be considered. Alternatively, the bottom plate portion 241 of the movable base plate 212 may be partially cut out including the central portion, and the bottom plate portion 241 may be provided with a see-through window. In any case, it suffices that the movable base plate 212 is rotated so that the back surface of the main controller 131 can be easily confirmed. The fixed base plate 211 may also be smaller or larger than the main control device 131, provided that the main control device 131 can be reliably mounted.

  (D) In the above embodiment, the shaft supporting portion is provided on the short side portion of the fixed base plate 211, but the shaft supporting portion may be provided on the long side portion of the fixed base plate 211. In this case, the amount of pulling the movable base plate 212 toward the front side is reduced, but the facing angle of the main control device 131 when viewed from the front of the slot machine is the same, and the confirmation of the main board 273 is also preferable. It can be implemented (similarly for reading side information of the IC chip 274).

  (E) In the above-described embodiment, both the fixed base plate 211 and the movable base plate 212 forming the pedestal member 210 are made of a transparent synthetic resin material. However, the fixed base plate 211 is made of a colored resin material. Alternatively, the fixed base plate 211 may be formed of a material other than a resin material, such as metal. Further, since the movable base plate 212 only needs to be able to visually recognize the back surface of the main control device 131, it can be changed to a colored resin material by adding a configuration such as providing a visual window in the bottom plate portion 241 of the movable base plate 212. Other than the resin material, for example, the material may be changed to metal or the like.

  (F) In the above embodiment, in order to guide the main control device 131 in the sliding direction on the movable base plate 212 and integrally hold the main control device 131, the side plate portions 242, 243 are provided with a return portion over the entire longitudinal direction. Although 242a and 243a are provided (see FIG. 12), the return portions 242a and 243a near the board mounting opening 245 may be partially removed. For example, in the configuration of FIG. 12, two return parts 242a and 243a from the right are removed. By partially removing the return portions 242a and 243a, the required slide amount of the main control device 131 on the movable base plate 212 is reduced, and the main control device 131 can be easily attached and detached.

  (G) The second pedestal member (movable base plate 212) may have a double-opening structure capable of rotating (opening) to the left and right sides. Specifically, rotary shaft portions are provided on the left and right ends of the fixed base plate 211, respectively, and the movable base plate 212 is rotatable about the rotary shaft portions in two opposite directions. As a result, for example, at the left and right ends of the main control device 131 (control board device), it is possible to pull the one desired by the operator or the like toward the front side.

  (H) The second base member (movable base plate 212) is mounted with the rotation base portion rotatably connected to the first base member (fixed base plate 211) and the control board device (main control device 131). It may be configured by a board mounting portion, and the board mounting portion may be connected to the rotating base so as to be able to be turned upside down. According to this configuration, the rotation base portion is rotated with respect to the first pedestal member, and the board mounting portion is turned upside down with respect to the rotation base portion, so that the housing facing surface of the control board device can be easily confirmed. become able to.

  (I) In the above embodiment, the movable base plate 212 is rotatably provided with respect to the fixed base plate 211 in the main board unit 200, but this configuration is changed as follows. For example, an extendable leg portion (specifically, an X-type extension link) is provided between the fixed base plate 211 and the movable base plate 212, and the base portions 211 and 212 are overlapped by contracting the leg portion. The main control device 131 is pulled toward the front side by keeping the above state and extending the legs to separate the movable base plate 212 from the fixed base plate 211. In this case, the movable base plate 212 can be moved in parallel with the fixed base plate 211. Further, two left and right leg portions are provided between the fixed base plate 211 and the movable base plate 212, and these leg portions are independently extended and contracted. According to this configuration, main controller 131 can be pulled in a state of being tilted to the left or right.

  (J) Illuminating means such as a lamp is provided inside the housing 11, and the lamp or the like (illuminating means) is turned on when the movable base plate 212 is rotated with respect to the fixed base plate 211. As a result, it becomes possible to easily confirm whether or not there is any illegal act on the main control device 131 or the pedestal device 210. The illuminating means may be attached to the housing 11 or the pedestal device 210.

  (K) In the above-described embodiment, in the first sealing portion of the main board unit 200, the insertion-side coupling portions 291 are arranged side by side in four rows on the front case body 271, and the receiving-side coupling portions 251 are correspondingly arranged. The movable base plate 212 is arranged in four lines in parallel, but this configuration is changed. At least one of the four receiving side coupling portions is provided on the back case body 272. Even with this configuration, it is still possible to realize an appropriate sealing structure.

  (L) The configuration relating to the sealing portion of the main control device 131 can be changed to another. Regarding the place where the seal portion is provided, besides the left and right short side portions of the substrate box (case bodies 271, 272), it may be provided on the long side portion of the substrate box (case bodies 271, 272). Further, instead of using the sealing screw, the sealing metal piece may be inserted into the sealing connecting portion.

  (M) In the above-described embodiment, in order to fix and attach the fixed base plate 211 to the back plate 11c of the housing 11, fastening is performed by screws 223 at two places on the left and right sides from the inside of the housing, and from the outside of the housing to the center. Although the configuration is such that the fastening is performed with the screw 233 at one place, this configuration is changed. For example, the fixed base plate 211 may be fastened only from the outside of the housing. In such a case, there may be two or more fastening points (specifically, the installation locations of the fixing brackets 225).

  (N) In the above-described embodiment, the main control device 131 including the main board 273 is configured to rotate the pedestal device, but the same configuration may be provided to control devices other than the main control device 131. Is also good.

  (O) In the above embodiment, the pedestal device 210 is composed of two pedestal members (the fixed base plate 211 and the movable base plate 212), and the main controller 131 is mounted on one of the pedestal members (the movable base plate 212). Was installed, but change it as follows. The pedestal device is composed of one pedestal member, and the pedestal member is fixed to the back plate 11c of the housing 11. Then, the main controller is rotatably (or displaceably) connected to the pedestal member. Even with this configuration, it is still possible to easily confirm the back surface (face facing the housing) of the main control device.

  (P) The gaming machine can be applied to a slot machine other than the slot machine. The point is that the gaming machine has an open housing on the front side and the control board device is housed inside the housing. The present invention can be suitably implemented in any gaming machine.
