(Description of lower door 14)
Further, the lower door 14 is provided with a table portion 40 so as to protrude to the front side of the slot machine. The table portion 40 has a shape in which an edge on the near side forms an arc shape, and an upper surface thereof is flat and inclined downward toward the near side. The table unit 40 is an operation unit provided with various operation members and the like operated by a player. On the table unit 40, a medal insertion device 41, bet switches 42, 43, and 44, a start switch 45 and a stop operating device 50 are provided.

  The medal insertion device 41 is provided on the right side of the upper surface of the table unit 40, and medals as investment values are inserted one by one from the insertion port of the medal insertion device 41. The medal insertion device 41 constitutes an input means for inputting the investment value. If attention is paid to the point that the medal insertion device 41 is accompanied by the operation of direct insertion of medals by the player, it can be said that the medal insertion device 41 constitutes a direct input means for directly inputting the investment value.

  The medals inserted from the medal insertion device 41 are sent to the passage switching means provided on the back surface of the lower door 14. That is, a selector 91 as a passage switching means is provided on the back surface of the lower door 14, and a medal inserted from the medal insertion device 41 is placed in either the storage passage 92 or the discharge passage 93 by the selector 91. Guided (see FIG. 4). The selector 91 is provided with a medal path switching solenoid. When the medal path switching solenoid is not excited, the medal path is set to the discharge path 93 side, and when excited, the medal path switching solenoid is switched to the storage path 92 side. In this case, the medal guided to the storage passage 92 is guided to the hopper device 110 described later. On the other hand, the medal guided to the discharge passage 93 is guided from the medal discharge port 72 provided in the lower door 14 to the medal tray 71 and returned to the player.

  The bet switches 42 to 44 are provided on the left side of the upper surface of the table unit 40, and the virtual medals credited (virtually stored) are inserted by a predetermined number of bets by pressing the bet switches 42 to 44. In this case, when the bet switch 42 is pushed, three virtual medals are inserted at a time, and when the bet switch 43 is pushed, two virtual medals are inserted at a time, and the bet switch 44 is pushed. As a result, one virtual medal is inserted at a time. Hereinafter, the bet switch 42 is also referred to as a MAX bet switch, the bet switch 43 is also referred to as a 2-bet switch, and the bet switch 44 is also referred to as a 1-bet switch. In the present embodiment, the MAX bet switch 42 is provided in a relatively large button shape, and the other bet switches 43 and 44 are provided in a relatively small button shape. The bet switches 43 and 44 are each provided in a semicircular shape so that the two are combined into a circular shape. Each bet switch 42 to 44 constitutes an input means for inputting an investment value together with the medal insertion device 41. Further, if the medal insertion device 41 is accompanied by an operation of direct insertion of medals by a player, the bet switches 42 to 44 are only accompanied by an operation of insertion of virtual medals based on credits. It can be said that it constitutes an indirect input means for indirectly inputting.

  The MAX bet switch 42 has a built-in lamp as a light emitting member (not shown) in order to urge that the maximum number of medals (three) that can be inserted per game is not reached. The lamp is turned on in a situation where the switch operation of the MAX bet switch 42 is valid, and prompts the operation of the switch 42. However, when there is no credited virtual medal or three medals have already been inserted. Turns off under circumstances. Here, instead of the above-described lighting, the player may make it easier to understand the prompt for medal insertion by blinking.

  The start switch 45 is provided on the front left side of the upper surface of the table portion 40 with respect to the MAX bet switch 42, and has substantially the same shape as the MAX bet switch 42. The start switch 45 is an operation member for starting rotation of each reel (rotating body) of a reel device described later, and is a start operation means or start operation operated to start rotation of each reel, that is, to start variable display. Configure the means.

  The stop operating device 50 is installed at a substantially central position of the table unit 40, has a substantially triangular prism shape, extends in the left-right direction of the slot machine 10, and is arranged side by side on the front side of the base unit 51. And three stop switches 52, 53, and 54. The stop switches 52 to 54 are provided to correspond to the reels to be stopped (left, middle, and right three-row reels), and are operated to stop each of the rotating reels individually. The operation means is configured. In this case, the stop switches 52 to 54 are provided slightly upward. Each of the stop switches 52 to 54 is in a state where it can be stopped when each reel is rotated at a constant speed, and a lamp (not shown) is lit and displayed during this state to notify that a stop operation is possible. When the rotation stops, it is turned off.

  When the player presses down the stop switches 52 to 54, it is considered that the stop switches 52 to 54 may be pressed with the thumb of the right hand or the left hand, for example. In this case, since the base portion 51 has a substantially triangular prism shape, a finger other than the thumb is turned to the rear inclined portion of the base portion 51 or the rear inclined portion of the base portion 51 is positively hooked. It can be used as a part.

  The player may push down each of the stop switches 52 to 54 with force, but the strength of the base 51 can be secured sufficiently and the malfunction of the stop operating device 50 occurs. Can be suppressed. Further, as will be described in detail later, in the slot machine 10, the positions of the stop switches 52 to 54 are lower than those of the conventional machine (see FIG. 26). Even in such a configuration, the stop switches 52 to 54 are provided slightly upward as described above, so that the operability is good.

  A button-like settlement switch 56 is provided above each of the bet switches 42 to 44. That is, the slot machine 10 has a credit function for storing and storing surplus inserted medals up to a predetermined maximum value (for example, 50 medals) or winning medals as credit medals. The credit medal is paid out as an actual medal by depressing the settlement switch 56 in a state where is stored and stored. In this case, if paying attention to the function of paying out the credited virtual medal as an actual medal, it can be said that the checkout switch 56 constitutes a checkout operation means for actually paying out the stored game value.

  It should be noted that the surplus inserted medals up to a predetermined maximum value (for example, 50 medals) or the “credit mode” set to store and memorize the winning medals as a credit medal, the surplus inserted medals, In the case of a slot machine capable of switching between the “direct mode” set so as to pay out the winning medal as an actual medal, the settlement switch 56 has a function as a changeover switch for mode switching. May be added. In this case, the settlement switch (switching switch) 56 is configured to be turned on when pressed once, turned off when pressed again, and switched on / off every time a pressing operation is performed thereafter. When the settlement switch 56 is on, the credit mode is selected, and when the settlement switch 56 is off, the direct mode is selected. If there is a credit medal when the credit mode is switched to the direct mode, the corresponding credit medal is paid out as an actual medal. Thereby, 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 settlement switch 56 constitutes a switching operation means for switching the input value and game value handling formats.

  Further, an information display unit 60 is provided between the game panel unit 22 and the table unit 40, that is, at the upper end portion of the lower door 14. The information display unit 60 displays a remaining number display unit 61 that displays the number of medals that have been activated and stored in the credit mode, and the number of remaining games, for example, in a special gaming state such as a big bonus or a regular bonus. A game number display unit 62 for displaying and an acquired number display unit 63 for displaying the number of acquired medals are provided. Although these display parts 61-63 are comprised by the 7 segment display, it is naturally possible to substitute with a liquid crystal display etc. FIG.

  Here, the information display unit 60 is located behind the stop operation device 50 described above, and it is difficult to see the information display unit 60 when viewed from a front view such as FIG. Since the base 51 constituting the device 50 has a substantially triangular shape and the back thereof is an inclined surface, and the player views the information display unit 60 obliquely from above in a normal gaming state, the information display unit 60 Is not difficult to see, and is easy to see.

  As shown in FIG. 2, a button-like return switch 65 is provided below the table portion 40 (below the medal insertion device 41). The return switch 65 is a switch that is pressed when a medal inserted into the medal insertion device 41 is jammed in the selector 91. When the switch 65 is pressed, the selector 91 is mechanically interlocked to operate. A medal jammed in the selector 91 is returned from a medal discharge port 72 described later. In addition, a table lamp portion 66 is installed near the top on the near side of the table portion 40.

  A lower plate 67 on which a model name, a character related to a game, and the like are displayed is attached below the table portion 40, and a medal tray 71 is provided below the lower plate 67. To the medal tray 71, medals are discharged from the hopper device 110 or the like inside the slot machine through the medal discharge port 72.

The power switch is a start switch, a reset switch for resetting various states of the slot machine 10, and a hall manager. Etc. have a setting key insertion hole for adjusting the appearance of medals. In other words, this slot machine 10 has a backup function of various data, and maintains the state at the time of power failure even if a power failure occurs, and the state at the time of power failure at the time of recovery from power failure (power recovery) You can return to. In this case, for example, when the game hall is closed, if the power is turned off in the normal procedure, the state before the turn-off is stored, but if the power switch is turned on while pressing the reset switch, the backup data is reset. It is like that. If the reset switch is pressed while the power switch is on, the error state is reset. Further, the setting state (winning probability setting process) of the slot machine 10 can be changed from “setting 1” to “setting 6” by operating the hole manager or the like by inserting the setting key into the setting key insertion hole. It has become.

  On the right side of the power supply box 100, a hopper device 110 is installed as a payout means for giving a medal to the player. FIG. 8 is a perspective view showing the configuration of the hopper device 110. The hopper device 110 includes a synthetic resin storage tank 111 that can store a large number of medals, and a payout device 112 that sequentially pays out medals in the storage tank 111. The storage tank 111 has a substantially square upper surface opening and a lower surface inclined obliquely downward. A lower opening 113 that communicates with the medal payout rotating plate of the payout device 112 is formed in a substantially central portion. The storage tank 111 has a medal discharge hole 114 formed at a corner of the tank, and a metal guide plate 115 is attached to the medal discharge hole 114.

The medal paid out from the payout opening 117 enters the discharge passage 93 through the opening 94 shown in FIG. 4 and the like, and is discharged to the medal tray 71 through the discharge passage 93.

  In addition, a reserve tank 120 is provided on the right side of the hopper device 110 to avoid storing a predetermined amount or more of medals in the storage tank 111. Accordingly, when a large number of medals are stored in the storage tank 111 and the height is equal to or higher than the height at which the guide plate 115 is provided, the surplus medals are guided to the spare tank 120 by the guide plate 115 and are stored in the spare tank 120. It will be stored at.

  In the back plate 11 c of the housing 11, a rectangular hole 121 is formed at an upper position of the storage tank 111. Through this hole 121, a medal replenishment passage that communicates from the outside of the housing to the inside of the housing can be installed, and automatic replenishment of medals to the storage tank 111 can be realized by installing the medal replenishment passage. It is like that. 7 and the like show a state in which the hole 121 is opened, but the hole 121 is closed when the hole 121 is not used (for example, when automatic replenishment of medals is not performed). It is in a state. However, in a state in which the hole 121 is closed, a notch is preferably provided around the hole 121 so that the hole 121 can be easily opened.

  Further, the back plate 11c of the housing 11 has a positioning hole 16 for aligning a main board unit 200, which will be described later, and an insertion hole through which a screw is inserted to fix the main board unit 200 to the back plate 11c. 17 to 19 are formed.

The door support fitting 131 is provided with support shafts 132 and 133 at two upper and lower portions, and each of the support shafts 132 and 133 is provided with a tapered shaft portion extending upward. Further, a hook receiving portion 135 for holding the lower door 14 in a closed state is attached to the right side plate 11 e of the housing 11.

  Metal support rail members 151 and 152 for mounting a reel unit 400 described later are fixed to the left and right side plates 11d and 11e of the housing 11 at the same height on the left and right. Although each of the support rail members 151 and 152 has the same structure, the left support rail member 151 will be described with reference to FIG. 6. The support rail member 151 serves as an attachment portion to the housing 11d. In addition to the mounting plate portion, a horizontal portion 151a that extends horizontally in the front-rear direction, a bent portion 151b that is bent vertically downward on the front side of the horizontal portion 151a, and a diagonally lower side on the rear side of the horizontal portion 151a. And a rearward inclined portion 151c that is bent. The bent portion 151b is provided with a tapered protrusion 151d so as to extend toward the front side. Similarly, the right support rail member 152 includes a horizontal portion 152a, a bent portion 152b, a rearward inclined portion 152c, and a protrusion 152d.

  A relay substrate 155 is provided on the left side plate 11 d of the housing 11 at substantially the center position. Lock metal fittings 156 and 157 are attached to the left side plate 11 d and the right side plate 11 e of the housing 11. The left lock fitting 156 includes a lever 160 pivotally supported on the left side plate 11d and a substantially U-shaped arm portion 161 connected to the middle of the lever 160. The arm portion 161 is a lever 160. It is the structure linked with rotation operation. In this case, the tip of the arm portion 161 moves forward by raising the lever 160 toward the front side. On the other hand, when the lever 160 is tilted to the back side of the housing 11, the distal end portion of the arm portion 161 moves backward. Similarly to the lock fitting 156, the right lock fitting 157 has a lever and an arm portion, and the tip of the arm portion moves forward by raising the lever toward the front side. On the other hand, the tip of the arm portion moves backward by tilting the lever to the back side of the housing. With these lock fittings 156 and 157, a reel unit 400 described later can be easily attached to and detached from the housing 11 without using a dedicated tool or the like. Furthermore, the lock fittings 156 and 157 are provided with sealing means for sealing the lock fittings 156 and 157 so as to leave a trace of unlocking. For example, as a sealing means, a sealing wire that makes it impossible to rotate the lever 160, or a sealing sticker that cannot be re-applied once peeled off and remains traced when peeled off is used. Provided on the metal fittings 156 and 157.

  FIG. 9 is an exploded perspective view of the housing 11, the main board unit 200, and the reel unit 400. The above-described devices and the like are arranged in the lower part inside the housing 11, and the positional relationship between the main board unit 200 and the reel unit 400 is as shown in FIG. The positional relationship between the main board unit 200 and the reel unit 400 in the housing will be described later. First, the reel unit 400 will be described in detail.

(General description of the reel unit 400)
Next, the structure of the reel unit 400 integrated with the upper door 13 will be described. 10 is a perspective view of the reel unit 400 as viewed obliquely from above, FIG. 11 is a front view of the reel unit 400, FIG. 12 is a side view of the reel unit 400, FIG. 13 is a rear view of the reel unit 400, and FIG. It is a disassembled perspective view which decomposes | disassembles and shows 400 for every main component. Note that a belt with a plurality of symbols is wound around the outer periphery of the three rows of reels constituting the reel unit 400, but FIG. 10 and the like show a state where the belt is not wound.

  The reel unit 400 is roughly divided into a resin base frame 401, metal support brackets 402 and 403 assembled to the left and right sides of the base frame 401, and a metal upper partition plate 404 assembled to the base frame 401. And a lower partition plate 405, and a reel device 406 disposed between the partition plates 404 and 405. Each component will be described in detail below.

(Description of base frame 401)
First, the single-piece | unit structure of the base frame 401 is demonstrated using FIG. The base frame 401 is integrally formed of, for example, a synthetic resin such as ABS, and roughly includes a left frame portion 411, a right frame portion 412, an upper frame portion 413, and a back frame portion 414. In this case, by making the base frame 401 an integrally molded product made of resin, it is possible to obtain merits such that the manufacture becomes easy and the weight of the reel unit 400 can be reduced.

  The left frame part 411 and the right frame part 412 have a substantially symmetrical shape, and a central connection part 415 and a lower connection part 416 are formed in the left frame part 411 as a connection part with the back frame part 414, and A center connecting portion 417 and a lower connecting portion 418 are formed in the frame portion 412. The lower connecting portions 416 and 418 are mounted portions that are mounted on the support rail members 151 and 152 (see FIG. 7) of the casing 11 when the reel unit 400 is assembled to the casing 11, and the lower surfaces thereof are front and rear. The flat surface extends in the direction. Further, the rear end portions of the lower connecting portions 416 and 418 partially project downward, and the portions serve as sliding portions 416a and 418a used when the reel unit 400 is mounted on the housing side. The sliding portions 416a and 418a protrude downward from the bottom portion of the base frame 401, and are formed so that the outline thereof forms a curved shape (R shape).

  As shown in FIG. 13 (rear view of the reel unit 400), the upper frame portion 413 is provided with a large number of reinforcing ribs 421, and the portion where the reinforcing ribs 421 are provided is a lattice-shaped reinforcing bar portion 422. It has become. Openings 423 are formed at a plurality of locations (three locations in the figure) behind the reinforcing bar portion 422. By holding the reinforcing bar portion 422 by hand and passing a finger through the opening portion 423, the base frame 401 (reel The unit 400) can be easily lifted. Further, a return portion 424 is formed at the front end portion of the reinforcing bar portion 422. When the reel unit 400 is assembled to the housing 11, the return portion 424 overlaps the front edge of the top plate 11a of the housing 11 (see FIG. 4). Thereby, even if it tries to infiltrate a wire, a film, etc. from the clearance gap between the housing | casing 11 and the upper door 13, it can be blocked | prevented and the illegal act is prevented.

  In the back frame portion 414, the lower back surface portion 432 below the center connecting portions 415 and 417 is formed to bulge rearward from the center connecting portions 415 and 417. As shown in FIG. 12 (side view of the reel unit 400), the lower back surface portion 432 has a substantially quarter circle shape when viewed from the side. The space in front of the lower back surface portion 432 is an installation area for the reel device 406. At the lowermost part of the back frame portion 414, projections 433 are provided at three locations so as to protrude inward.

  On the other hand, as shown in FIG. 12, the upper back surface portion 431 above the central connecting portions 415 and 417 extends substantially straight from the central connecting portions 415 and 417 to the upper frame portion 413 when viewed from the side. In addition, an opening 427 is formed in the upper back surface portion 431, and a surrounding portion is a surrounding portion 428. The opening 427 is formed in a substantially horizontally long rectangular shape having a predetermined size. The opening 427 is formed in a shape and size that allows the main board unit 200 described later to move to the front side of the main controller 201. The details will be described later.

  As described above, the rear frame portion 414 is formed in a stepped shape, so that a sufficient installation area of the reel device 406 can be secured in the front area of the lower back surface section 432. Therefore, the reel device 406 can be accommodated without difficulty. Further, since the lower portion of the lower back surface portion 432 has a substantially quarter circle shape, even when the medal supply passage is installed in the hole 121 (see FIG. 7) provided in the back plate 11c of the housing 11, the medal The supply passage can be provided without interfering with the base frame 401.

  At the lower corner of the rear frame portion 414, guide ribs protrude downward from the slide portions 416a and 418a provided on the left frame portion 411 and the right frame portion 412 in the same manner as the slide portions 416a and 418a. 435, 436 are provided. The guide ribs 435 and 436 have the depth position of the base frame 401 substantially the same as that of the sliding portions 416a and 418a, and are fixed to the housing 11 with respect to the outer surfaces of the lower connecting portions 416 and 418 of the left and right frame portions 411 and 412. The support rail members 151 and 152 are provided at the inner position by the width. The guide rib may be provided only on either the left or right side.

  According to the above configuration of the base frame 401, when the reel unit 400 is assembled to the housing 11, the sliding portions 416 a and 418 a of the lower connecting portions 416 and 418 are in contact with the support rail members 151 and 152 on the housing 11 side. The unit 400 is slid forward or backward. FIG. 16 is a schematic view showing a state when the unit is assembled with the reel unit 400 viewed from the side. However, in FIG. 16, member numbers corresponding to the configuration on the left side of the base frame 401 are given. Reference numeral 465 shown in the figure is a bent portion provided at the front edge of the lower partition plate 405 (see FIG. 20), and the bent portion 465 engages with the protrusion 151d of the support rail member 151. An engagement hole is formed (details of the lower partition plate 405 will be described later).

  As shown in FIG. 16A, when the reel unit 400 is mounted, the front side is slightly lifted with the sliding portion 416a of the base frame 401 placed on the horizontal portion 151a of the support rail member 151. The reel unit 400 is pushed into the back side of the casing (right side in the figure). By this pushing, the reel unit 400 moves so that the sliding portion 416a slides on the support rail member 151. At this time, since the sliding portion 416a is provided near the back surface of the base frame 401, the weight of the reel unit 400 can be quickly deposited on the housing 11 side. Further, since the outer shape of the sliding portion 416a is curved (R-shaped), the sliding portion 416a and the horizontal portion 151a of the support rail member 151 are always in the same state regardless of the inclination state of the reel unit 400. Contact. Accordingly, the same frictional resistance can always be applied to the contact portion of the sliding portion 416a regardless of the tilt state of the reel unit 400.

  Then, as shown in FIG. 16B, when the sliding portion 416a reaches the rear inclined portion 151c of the support rail member 151, the sliding portion 416a is guided and fitted into the rear inclined portion 151c, and the reel unit 400 is inserted. Mounted in place. At this time, if the rear inclined portion 151c is not provided, the reel unit 400 suddenly falls and receives an impact, but according to the configuration of the present embodiment, the reel unit 400 is obliquely lowered along the rear inclined portion 151c. Therefore, there is no inconvenience such as receiving an impact. Further, in the state where the reel unit 400 is completely installed, the sliding portion 416a is fitted in the rear inclined portion 151c, so that the inconvenience that the reel unit 400 slides to the near side does not occur.

  On the other hand, when detaching the reel unit 400, the sliding unit 416a is lifted up to the horizontal part 151a along the rear inclined part 151c by pulling the reel unit 400 toward the front side from the mounted state. At this time, since the sliding portion 416a is guided to the rear inclined portion 151c, the pulling is relatively easy. Then, the reel unit 400 is pulled toward the front side of the housing so that the sliding portion 416a slides on the horizontal portion 151a. Thereby, the separation of the reel unit 400 is completed.

  FIG. 17 is a partially broken perspective view of the reel unit 400 assembled to the housing 11 as seen obliquely from below. As shown in FIG. 17, when the reel unit 400 is assembled, the inner end portion of the support rail member 151 hits the guide rib 435 provided at the lower corner portion of the rear frame portion 414, thereby guiding the reel unit 400. Therefore, the inconvenience that the reel unit 400 is inserted obliquely with respect to the housing 11 is restricted (not shown for convenience, but the right guide rib 436 functions in the same manner).

  Here, the tip end portions of the guide ribs 435 and 436 are configured to protrude downward from the sliding portions 416a and 418a. Therefore, when the reel unit 400 is placed on the floor or the like at the time of unit replacement or the like, not the sliding portions 416a and 418a but the tip portions of the guide ribs 435 and 436 will hit the floor or the like. As a result, it is possible to prevent problems such as the surface of the sliding portions 416a and 418a being damaged and the slipping condition becoming worse, or the sliding portions 416a and 418a being damaged. That is, the guide ribs 435 and 436 also have a protection function for the sliding portions 416a and 418a.

(Description of support brackets 402 and 403)
Next, the structure of the support metal fittings 402 and 403 will be described. The support fittings 402 and 403 have a function as a fixture for the upper door 13 and a function as a reinforcing material for the base frame 401.

  As shown in FIG. 11, the support metal fitting 402 has a long shape, and the support metal fitting 402 is provided with support shafts 441 and 442 at two locations on the upper and lower sides. The length of the support fitting 402 is substantially the same as the length of the left frame portion 411 of the base frame 401. Each of the support shafts 441 and 442 is provided with a tapered shaft portion extending upward. The support fitting 402 is assembled to the left frame portion 411 of the base frame 401 and is fixed by a fastener (not shown) such as a screw. When the upper door 13 is supported by the support metal fitting 402 while the support metal fitting 402 is fixed to the base frame 401, the upper door 13 can be opened and closed with respect to the base frame 401 (reel unit 400).

  Similarly, the support fitting 403 has a long shape, and the support fitting 403 is provided with three hook receiving portions 444, 445, and 446. The support metal fitting 403 is assembled to the right frame portion 411 of the base frame 401 and is fixed by a fastener (not shown) such as a screw. In a state where the support metal fitting 403 is fixed to the base frame 401, the upper door 13 supported by the base metal frame 401 (reel unit 400) so as to be openable and closable is held in a closed state by the support metal fitting 403.

  FIG. 18 is a front view of the state in which the upper door 13 is mounted on the reel unit 400. As shown in the figure, the vertical length of the upper door 13 is shorter than the vertical length of the base frame 401, and when the upper door 13 is mounted on the reel unit 400, a part of the reel unit 400 is upper. It is exposed below the door 13. In this case, of the three hook receiving portions 444 to 446 provided on the support metal fitting 403, the upper two hook receiving portions 444 and 445 function as members that hold the upper door 13 in a closed state. The lowermost flange receiving portion 446 functions as a member that holds the lower door 14 in a closed state together with the flange receiving portion 135 (see FIG. 7) provided on the housing 11 side.

  Further, as shown in FIG. 10 and the like, a hook metal fitting 443 is attached to the upper part of the support metal fitting 402. As shown in FIG. 4, this hook metal fitting 443 is used to fix the reel unit 400 in a state where the arm portion 161 of the lock metal fitting 156 provided on the left side plate 11 d of the housing 11 is hung and attached to the housing 11. Yes, it forms unit fixing means together with the lock fitting 156. A similar hook metal fitting is also attached to the right support metal fitting 403, but the illustration is omitted. The hook metal fitting of the support metal fitting 403 is hung on the arm portion of the lock metal fitting 157 provided on the right side plate 11e of the housing 11, and like the hook metal fitting 443, the reel unit 400 is fixed while being attached to the housing 11. (They also constitute unit fixing means).

(Description of the upper partition plate 404 and the lower partition plate 405)
Next, the configuration of the upper partition plate 404 and the lower partition plate 405 will be described with reference to FIGS. 19 and 20. As shown in FIG. 19, the upper partition plate 404 has a long plate-like base portion 451, and a circuit board 452 for driving a reel is mounted on the base portion 451. The circuit board 452 is a board device that relays electrical connection between the reel device 406 and the main controller 201. On the circuit board 452, a clamp portion 456 for bundling electrical wiring extending from the reel device 406 (three reels 471 to 473 described later) is provided. Further, both the left and right sides of the base portion 451 are bent at right angles to form attachment portions 453 and 454 for the base frame 401. The upper partition plate 404 is attached to the base frame 401 by assembling the attachment portions 453 and 454 to the central coupling portions 415 and 417 of the base frame 401 with fasteners such as screws. The front side edge portion of the base portion 451 is provided so as to recede from the front end portions of the attachment portions 453 and 454. The front side edge portion of the base portion 451 is bent at a right angle, and this is an upper reel support portion 455. The upper reel support 455 has two screw holes 455a at three locations.

  Further, as shown in FIG. 20, the lower partition plate 405 has a long plate-like base portion 461. The left and right sides and the rear side of the base portion 461 are bent at right angles to form attachment portions 462, 463, and 464 for the base frame 401. The lower partition plate 405 is attached to the base frame 401 by assembling the left and right attachment portions 462 and 463 to the lower connection portions 416 and 418 of the base frame 401 with fasteners such as screws. In addition, the rear mounting portion 464 is formed with an engagement hole 464 a that engages with a protrusion 433 provided on the back frame portion 414 of the base frame 401.

  Bending portions 465 and 466 are formed at the front edge of the base portion 461 so as to be bent downward on both the left and right sides. The supporting rail members 151 and 165 fixed to the housing 11 are formed in the bent portions 465 and 466. Engagement holes 465a and 466a that engage with the protrusions 151d and 152d of 152 are formed. Between the bent portions 465 and 466 when the base portion 461 is viewed from above, a shape in which a part of the base portion 461 is cut away (in other words, a shape in which a part is retracted) is formed. .

  The front edge of the base portion 461 is bent at a right angle between the bent portions 465 and 466, and this is a lower reel support portion 467. The lower reel support portion 467 has two screw holes 467a formed at three locations.

  Here, when the bent portions 465 and 466 formed at the front edge of the lower partition plate 405 (base portion 461) and the lower reel support portion 467 are compared, as shown in FIG. The part 467 has a slightly longer configuration (A in FIG. 12). That is, the front end portion of the lower reel support portion 467 is configured to be the lowermost portion. In this case, the bent portions 465 and 466 are an important configuration for positioning the reel unit 400 with respect to the casing 11 and further fixing the reel unit 400. When the unit is replaced, the reel unit 400 is placed on the floor or the like. It is necessary to prevent deformation and damage even when placed on the reel unit 400. However, the reel unit 400 can be made ineffective by adopting a configuration in which the tip of the lower reel support portion 467 is at the bottom as described above. Even when placed on the floor or the like, deformation or breakage of the bent portions 465 and 466 can be prevented.

(Description of reel device 406)
Next, the configuration of the reel device 406 will be described with reference to FIGS. 21 and 22. As shown in FIG. 21, the reel device 406 includes three reels 471 to 473 (a left reel 471, a middle reel 472, and a right reel 473), which are variable display means. Configure. Normally, a state in which a film-like belt is wound around the outer periphery is referred to as a reel, but here, the reel will be described without a belt. Each of the reels 471 to 473 is formed in a cylindrical shape (annular shape) having the same diameter, and is supported rotatably so that the central axis thereof becomes the rotation axis of the reel. A stepping motor is connected to each of the reels 471 to 473, and each of the reels 471 to 473 can be individually rotated, that is, independently driven by the driving of each stepping motor. The reels 471 to 473 including the motor drive system have exactly the same configuration. Here, the configuration will be described using the left reel 471 as an example with reference to FIG.

  As shown in FIG. 22, the reel 471 is a cylindrical skeleton member that forms a cylindrical cage, and a belt-like belt (not shown) is wound around the outer peripheral surface thereof. A drive shaft of a stepping motor 475 is attached to a boss formed at the center of the reel 471. Accordingly, when the drive shaft of the stepping motor 475 is rotated, the reel 471 rotates around the drive shaft.

  The reel 471 is rotatably supported by a metal reel plate 476. Specifically, a stepping motor 475 is fixed to a substantially central portion of the reel plate 476. The reel plate 476 has a vertically standing plate shape, and an upper mounting portion 477 is bent on the upper side and a lower mounting portion 478 is bent on the lower side. Two screw holes 477a and 478a are formed in each mounting portion 477 and 478, respectively. The upper mounting portion 477 constitutes a reel mounting portion with respect to the upper reel support portion 455 of the upper partition plate 404. The reel 471 is attached to the upper partition plate 404 by screwing a fastener such as a screw into the screw holes 455a and 477a of each part. The lower attachment portion 478 constitutes a reel attachment portion for the lower reel support portion 467 of the lower partition plate 405, and the lower attachment portion is provided on the lower reel support portion 467 of the lower partition plate 405. The reel 471 is attached to the lower partition plate 405 by screwing a fastener such as a screw into the screw holes 467a and 478a of the respective parts with the 478 stacked.

  A backlight device 479 that emits light toward the outer periphery of the reel is disposed on the inner periphery of the reel 471.

  Although not shown, the reel plate 476 is provided with a reel index sensor (rotational position detection sensor) in which a light emitting element and a light receiving element are held at a predetermined interval. The boss portion of the reel 471 is provided with a sensor cut van that can pass between the light emitting element and the light receiving element of the reel index sensor when the reel rotates. Accordingly, every time the reel 471 rotates, the tip of the sensor cut bang passes between the light emitting element and the light receiving element of the reel index sensor, and the reel index sensor detects the passage. Then, the detection signal is output to the main control device 201 described later, and the main control device 201 detects the angular position of the reel 471 for each rotation based on the detection signal.

  For example, the stepping motor 475 is set to rotate once by applying a drive signal of 504 pulses (also referred to as an excitation signal or an excitation pulse; the same applies hereinafter). The rotation position of the stepping motor 475, that is, the reel is set by this excitation pulse. The rotational position of 471 is controlled. Here, a large number of symbols as identification information are printed at equal intervals on the outer peripheral surface of the belt of the reel 471. When 21 symbols are attached in the long side direction (circumferential direction) of the belt, 24 pulses (= 504 pulses ÷ 21 symbols) are required to switch from one symbol to the next symbol at a predetermined position. In this case, the rotational position of the reel 471 is detected based on the number of pulses from when the detection signal of the reel index sensor is output, and the rotational position of the reel 471 is controlled based on the result.

  The other reels 472 and 473 have the same configuration. In FIG. 21, the corresponding reference numerals are attached, and briefly described. A drive shaft of a stepping motor 481 is attached to the center of the middle reel 472, and the drive shaft of the motor 481 rotates to rotate. The reel 472 rotates around the drive shaft. The reel plate 482 has an upper mounting portion 483 and a lower mounting portion 484. A backlight device 485 is disposed on the inner peripheral side of the reel 472.

  A drive shaft of a stepping motor 491 is attached to the center portion of the right reel 473, and the reel 473 rotates around the drive shaft as the drive shaft of the motor 491 rotates. The reel plate 492 has an upper mounting portion 493 and a lower mounting portion 494. A backlight device 495 is disposed on the inner peripheral side of the reel 473.

  A state in which the reels 471 to 473 are assembled to the reel unit 400 is shown in FIGS. In this state, each of the reels 471 to 473 can be detached individually, and one part can be replaced.

  Since the reels 471 to 473 including the motor drive system have exactly the same configuration, the electrical wiring is naturally long, but the electrical wiring is bundled and clamped on the circuit board 452 on the upper partition plate 404. The portion 456 is restrained. Since the reels 471 to 473 including the motor drive system have exactly the same configuration, it is possible to realize cost reduction in design and manufacturing.

  In a state where the reel unit 400 is assembled to the slot machine 10, a part of the surface of each reel 471 to 473 (a part of the belt) can be visually recognized through the display window 23 provided on the upper door 13. In this case, when each of the reels 471 to 473 is rotated forward, the surface (the belt symbol) of each of the reels 471 to 473 is projected through the display window 23 as if moving from top to bottom. Of the symbols attached to each of the reels 471 to 473, the number of symbols that can be visually recognized through the display window 23 is limited to a predetermined number mainly determined by the vertical length of the display window 23. In this embodiment, three reels are provided. For this reason, when all the reels 471 to 473 are stopped, 3 × 3 = 9 symbols are visible to the player.

(Description of entire reel unit 400)
Next, the entire configuration of the reel unit 400 will be described again. As shown in FIG. 10, an upper partition plate 404 and a lower partition plate 405 are assembled to the base frame 401 between the right frame portion 411 and the left frame portion 412, and below the upper partition plate 404. Is formed so as to surround an installation area of the reel device 406 (hereinafter referred to as a reel installation area). In the reel installation area, the reel device 406 is installed between the upper partition plate 404 and the lower partition plate 405 so as to be rotatable in the vertical direction.

  In this case, the reel installation area is formed in a predetermined range in the front-rear direction of the housing 11 (generally the same range as the front-rear length of the housing 11). Therefore, assuming that the reel unit 400 is mounted in the housing 11, the lower back surface portion 432 of the base frame 401 is in a positional relationship close to the back plate 11 c of the housing 11 as shown in FIG. 12. In this case, the gap dimension D1 between the lower back surface portion 432 and the back plate 11c is smaller than the thickness dimension D2 of the main board unit 200 (D1 <D2). Therefore, the main board unit 200 removed from the back plate 11c can be prevented from being taken out of the housing 11 through the space between the lower back surface portion 432 and the back plate 11c. Further, the reel device 406 is provided in a range up to the vicinity of the back plate 11 of the housing 11.

  On the other hand, since the upper back surface portion 431 of the base frame 401 is located in front of the lower back surface portion 432, a space is formed between the upper back surface portion 431 and the back plate 11 c of the housing 11. Thereby, the main board unit 200 can be installed on the back plate 11c of the housing 11 facing the upper back surface portion 431 without difficulty. Further, as shown in FIG. 10 and the like, in the base frame 401, various substrates, gaming machine components, and the like are not disposed in the front region of the upper back surface portion 431, and nothing is installed. Therefore, in a state where the main board unit 200 is installed on the back plate 11c of the housing 11, there is nothing that prevents the main board unit 200 from being visually recognized from the front.

  The upper partition plate 404 is provided with a circuit board 452 that relays electrical connection between the reel device 406 and the main control device 201. Therefore, the circuit board 404 can be arranged efficiently, and the electrical wiring and the like extending from the reel device 406 can be conveniently collected.

(Description of reel design)
Here, the symbols attached to the reels 471 to 473 will be described. FIG. 23 shows a symbol arrangement drawn on the belt wound around each of the reels 471 to 473. As shown in the figure, each of the reels 471 to 473 is provided with 21 symbols in a row. Numbers 1 to 21 are assigned to the respective reels 471 to 473, but are given for convenience of explanation, and are not actually assigned to the reels 471 to 473. However, in the following description, the number is used for explanation.

  As the symbols, there are a “7” symbol (for example, the left belt 20th) and a “youth” symbol (for example, the left belt 19th) as the first special symbol for shifting to the big bonus game. In addition, there is a “BAR” symbol (for example, the 14th left belt) as the second special symbol for shifting to the regular bonus game. Further, there is a “replay” symbol (for example, the eleventh left belt) as a 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) as the small character symbols from which the small character is paid out. Belt 4th). Each of the left, middle, and right belts is provided with the above-described symbols on the assumption that the number of symbols and the arrangement order are completely different.

  Each reel 471 to 473 of the reel unit 41 is an example of variable display means for variably displaying the identification information, and constitutes a main display unit. However, the variable display means may have other configurations. For example, a cylindrical frame that constitutes the reels 471 to 473 is manufactured, and the outer peripheral surface of the cylindrical frame is provided with a design (so-called drum device) by printing, sticking a sticker, or the like. Or a mechanical reel configuration. In this case, the belt trajectory may not be a perfect circle but may be an ellipse. Further, instead of or in addition to the mechanical reel configuration, a device that variably displays identification information by electrical display such as a liquid crystal display or a dot matrix display may be provided. It is possible to have abundant variations.

By this connection, the upper door 13 and the lower door 14 are integrally opened and closed. In this case, if the configuration is such that only the lower door 14 can be opened, the act of opening only the lower door 14 is relatively inconspicuous and is likely to be performed as an illegal act. Since it is impossible to open the lower door 14 alone at normal times (that is, in a state where the connecting plate 651 is attached), it is possible to suppress fraud. That is, when the front door 12 is opened for fraudulent purposes, the upper door 13 and the lower door 14 are both opened, so that the opening action is conspicuous, thereby preventing the fraudulent action.

  A bent portion 616a bent in the horizontal direction is formed at the lower end portion of the interlocking rod 616 provided in the upper door 13, and the upper end portion of the interlocking rod 646 provided in the lower door 14 is bent in the horizontal direction. A bent portion 646a is formed. The bent portions 616a and 646a of the interlocking rods 616 and 646 are in contact with each other when the upper door 13 and the lower door 14 are connected.

  The interlocking rods 616 and 646 provided on the upper door 13 and the lower door 14 constitute a locking mechanism that holds the doors 13 and 14 in a locked state that cannot be opened, and are provided at the rear left end of the lower door 14. The base frame 645 is provided with a key cylinder 655 as an unlocking operation unit. The key cylinder 655 is provided so as to extend in the front-rear direction of the slot machine 10, and the cylinder front surface (the side where the key insertion hole is installed) is exposed from a key hole 80 provided on the door front surface. A slot machine locking mechanism includes a locking mechanism including interlocking rods 616 and 646 for the upper and lower doors 13 and 14, a key cylinder 655, and an operation key (not shown) inserted into the key cylinder 655 and rotated in a predetermined direction. Configure the device. As the key cylinder 655, Omlock (registered trademark) having a high function of preventing unauthorized unlocking may be used.

  In such a case, when the operation key is rotated clockwise with the operation key inserted into the key cylinder 655, the interlocking rod 646 moves upward (when viewed from the back of the door, the key cylinder 655 rotates counterclockwise. To turn to). As a result, when the lower end 14 of the interlocking bar 646 of the interlocking bar 646 moves downward in the lower door 14 and the lower door 14 is closed with respect to the housing 11, the bar bar 647, 648 and the reel The locked state (that is, the locked state) between the hook receiving portion 446 on the unit 400 side and the hook receiving portion 135 on the housing 11 side is released. As a result, the lower door 14 can be opened with respect to the housing 11.

  At this time, the bent portion 616a of the interlocking rod 616 on the upper door 13 side is lifted by the bent portion 646a of the interlocking rod 646 on the lower door 14 side, and the upper door 13 is interlocked with the interlocking rod 646 on the lower door 14 side. The side interlocking rod 616 moves upward. For this reason, when the top hooks of the hooks 617 and 618 of the interlocking hook 616 move downward in the upper door 13 and the upper door 13 is closed with respect to the housing 11 (reel unit 400), The locked state (that is, the locked state) between 618 and the hook receiving portions 444 and 445 on the reel unit 400 side is released. Thereby, the upper door 13 can be opened with respect to the housing | casing 11 (reel unit 400).

  Incidentally, when the operation key is rotated in the reverse direction (counterclockwise direction), the interlocking rod 646 moves downward, and the slot machine 10 is reset by detecting it by a sensor (not shown). Only the interlocking rod 646 on the lower door 14 side moves, and the interlocking rod 616 on the upper door 13 side does not move.

(Comparison between this machine and conventional machine)
Here, the main characteristic configuration of the slot machine 10 in the present embodiment will be described based on a comparison with an existing slot machine. For convenience, the slot machine 10 of the present embodiment is also referred to as “this machine”, and the existing slot machine 1000 is also referred to as “conventional machine”. FIG. 26 compares the front configuration of the slot machine. FIG. 26A shows the configuration of this machine, and FIG. 26B shows the configuration of the conventional machine. FIG. 27 compares the internal structure of the slot machine. FIG. 27A shows the internal structure of this machine, and FIG. 27B shows the internal structure of the conventional machine.

  The main configuration of the existing slot machine 1000 will be briefly described. In FIG. 26B, like the present machine, the conventional machine (slot machine 1000) has a housing 1001 that opens to the front, and a front door 1002 is attached to the front side. The size of the housing is the same for both this machine and the conventional machine. An auxiliary display portion 1003 is provided at the upper part of the front door 1002, and a display window 1004 is provided below the auxiliary display portion 1003. Below the display window 1004, an operation unit 1010 is provided that projects to the front side. A medal insertion device 1011 and a bet operation switch 1012 are provided on the upper surface of the operation unit 1010, and a start lever 1013 and three stop buttons 1014 are provided on the front surface of the operation unit 1010. A medal tray 1015 is provided below the front door 1002.

  In FIG. 27B, the casing 1001 is provided with a partition plate 1021 that divides the interior of the casing 1001 into upper and lower portions, and a reel unit 1022 is placed on the partition plate 1021. A main control device 1023 is attached above the reel unit 1022 on the back plate of the housing 1001. A power supply device 1024 and a hopper device 1025 are disposed below the partition plate 1021.

  Based on FIG. 26, the front configuration will be compared. First of all, the size of the upper game panel 21 is impressed. As described above, a large liquid crystal device of about 15 inches is mounted behind the game panel 21 to perform various display effects. And the installation position of the display window 23 has become lower than the conventional machine accompanying the enlargement of the liquid crystal device. In comparison, in the conventional machine, the height from the lower surface of the machine to the center of the display window 1004 is “L11”, whereas in this machine, the height from the lower surface of the machine to the center of the display window 23 is “L1”. (L1 <L11).

  In addition, because the position of the display window is shifted downward, the position of various switches on the operation unit is also shifted downward. In the conventional machine, the height from the machine bottom to the various switches is "L12". In this machine, the height from the machine bottom surface to various switches is “L2” (L2 <L12). In this case, the operation unit is configured as the table unit 40 in order to maintain the operability of various switches even when the operation unit is shifted downward. Further, in order to improve the operability of the starting operation means, the lever member (start lever 1013) of the conventional machine is changed to a button-like switch member (start switch 45).

  Next, the internal structure of the housing will be compared based on FIG. The biggest difference here is the position of the reel unit. That is, with reference to the reel unit mounting member (the lower partition plate 405 in this machine, the partition plate 1021 in the conventional machine), the height from the machine lower surface to the partition board 1021 in the conventional machine is “L13”. On the other hand, in this machine, the height from the machine lower surface to the lower partition plate 405 is “L3” (L3 <L13). This difference in the position of the reel unit is the difference in the position of the display window on the front surface of the slot machine.

  Along with the change in position of the reel unit, the lower area of the reel unit 400 is narrowed in this machine, and therefore the hopper device 110 is changed to a structure with a short height. Further, in this case, the distance between the partition plate below the reel unit and the hopper device is “L14” in the conventional machine, whereas “L4” in this machine (L4 <L14). This is because it is desired to mount a large hopper device in the lower area of the reel unit that is narrowed as described above. However, in this machine, as the height of the hopper device 110 is reduced, the horizontal dimension (front and rear, left and right) of the storage tank 111 is increased to ensure the tank capacity.

  Under such installation conditions of the hopper device 110 in this machine, since the distance between the partition plate 405 below the reel unit and the hopper device 110 is short, it may be difficult to supply or remove medals from the storage tank 111. Is done. On the other hand, in this machine, as described above, the front edge portion of the lower partition plate 405 is shaped such that a part thereof is cut between the left and right bent portions 465 and 466. This shape corresponds to the position of the hopper device 110, thereby facilitating the operation of supplying or taking out medals from the hopper device 110 (storage tank 111).

  In the case of this machine, support rail members 151 and 152 are provided on the left and right side plates 11d and 11e of the housing 11, respectively, and the reel unit 400 is mounted on the support rail members 151 and 152. Since the partition plate that divides the upper and lower sides is not provided, the installation area of the hopper device 111 and the power supply box 100 is not partitioned when the reel unit 400 is not mounted. Therefore, even if the lower region of the reel unit 400 is narrowed as described above, there is no inconvenience that it is difficult to install the hopper device 111 and the power supply box 100. The merit can be confirmed from FIG.

(Description of reel unit 400 replacement work)
Here, the exchange operation of the reel unit 400 at the time of model change in the game hall will be described. In this case, first, the lower door 14 is unlocked using a prescribed operation key, and the lower door 14 is opened together with the upper door 13. Further, the connecting plate 651 connecting the upper and lower doors 13 and 14 is removed. At this time, the electrical wiring connector that connects the reel unit 400 and other members (the power supply box 100, the hopper device 110, etc.) is removed. Thereafter, the locked state of the lock fittings 156 and 157 fixing the reel unit 400 to the housing 11 is released. That is, the lever 160 of the lock fitting 156 is raised to the near side from the left side plate 11 d of the housing 11, and the arm portion 161 moved forward is detached from the hook fitting 443 of the support fitting 402. Further, similarly to the lock fitting 156, the lock fitting 157 raises the lever from the right side plate 11 e of the housing, and removes the arm portion moved forward from the hook fitting of the support fitting 403. Then, only the upper door 13 is closed. Thereafter, while slightly lifting the front side of the reel unit 400, the unit 400 is pulled toward the front side while sliding on the support rail members 151 and 152, and the reel unit 400 is detached.

  Thereafter, the new reel unit 400 is mounted according to the work procedure reverse to that at the time of detachment. That is, the new reel unit 400 is pushed into the back of the housing while sliding on the support rail members 151 and 152, and the reel unit 400 is mounted on the housing 11. Then, the upper door 13 is once opened and the tip of the arm portion 161 of the lock fitting 156 is hung on the hook fitting 443 of the support fitting 402. Then, the lever 161 is tilted to the back side of the housing 11 to be in a locked state. Similarly to the lock fitting 156, the lock fitting 157 is brought into a locked state. Thereby, the reel unit 400 is fixed to the housing 11. Further, the lock fittings 156 and 157 in the locked state are appropriately provided with sealing means. For example, the lock fittings 156 and 157 are provided with a sealing wire and a seal.

  In addition, an electrical wiring connector that connects the reel unit 400 and various other members (the power supply box 100, the hopper device 110, etc.) is connected. Further, the upper door 13 and the lower door 14 are connected by a connecting plate 651. Thereafter, when the upper door 13 and the lower door 14 are closed together, the slot machine 10 is locked, and the unit replacement is completed. At the time of model change, after removing the reel unit 400 from the casing 11 as described above, the main board unit 200 attached to the back plate 11c of the casing 11 is removed and a new main board unit is attached. . Further, the lower plate 67 is replaced.

(Outline explanation of the game)
Next, the outline of the game performed by the player in the slot machine 10 having the above configuration will be briefly described. At the start of the game, when a player first inserts a predetermined number of medals into the medal insertion device 41, a bet is set according to the number of medals inserted. At this time, if the number of inserted medals is larger than the maximum bet (3 bets), in the credit mode, surplus inserted medals are credited (virtual storage) with the maximum number being 50, and in the direct mode, surplus inserted medals. Is returned to the medal tray 71. Or, when a credit of a predetermined number or more remains in advance in the credit mode, when the player presses one of the bet switches 42 to 44, a bet is set correspondingly.

  When the player presses the start switch 45 after setting the bet, the left, middle, and right reels 471 to 473 of the reel unit 400 start rotating all at once or in a predetermined order. Thereafter, when the player presses the stop switches 52 to 54, the rotation of the corresponding reels 471 to 473 is stopped in accordance with the pressing timing. Alternatively, the rotation of the reels 471 to 473 is stopped when a specified time elapses without pressing the stop switches 52 to 54 after the rotation of the reels 471 to 473 is started.

  When the rotation of the left, middle, and right reels 471 to 473 is stopped, if a stop symbol visually recognized through the display window 23 matches a prescribed symbol, a prize is awarded and a predetermined number of medals are paid out. That is, in the configuration of the present embodiment, when the symbols are stopped, a total of nine symbols of 3 × 3 in length and width can be visually recognized through the display window 23. For the nine symbols, for example, the upper stage A total of five effective lines are set: the row (upper line), the middle row (middle line), the lower row (lower line), the upper right diagonal row (upward right line), and the lower right diagonal row (lower right line). Yes. Then, when a prescribed symbol stops on any of these active lines, a corresponding number of medals are paid out.

  Here, an example of the number of payouts related to each symbol when winning is described. For the symbols described below, refer to the symbols in FIG.

  Regarding the small role design, when the “Watermelon” design is aligned with the left, middle and right on the active line, 15 medals are paid out. When the “Bell” design is aligned with the left, middle and right on the effective line Pays out 8 medals, and when the “cherry” symbol on the left reel 471 stops on the active line, 2 medals are paid out. That is, the “cherry” symbols of the middle reel 472 and the right reel 473 are irrelevant to the medal payout. In addition, for the “cherry” symbol, medals are paid out regardless of the combination with other symbols, and therefore, a plurality of effective lines of the left reel 471 overlap each other (specifically, at the upper or lower level). When the “cherry” symbol is stopped, medals are paid out by multiplying the number of overlapping active lines. As a result, in this embodiment, four medals are paid out.

  As for other symbols, when the “7” symbol or “youth” symbol, which is a combination of the first special symbol (big bonus symbol), is aligned with the left, middle and right on the active line in the same symbol The 15 medals are also paid out when the “BAR” symbol which is a combination of 15 medal payouts and the second special symbol (regular bonus symbol) is aligned with the left, middle and right on the active line. In the present embodiment, for example, a case where the “7” symbol and the “cherry” symbol are established simultaneously may occur, but in this case, 15 medals are paid out. This is because the upper limit number for one medal payout is set to 15.

  Further, when the “replay” symbol, which is the combination of the third special symbol, is aligned with the left, middle, and right on the active line, the medal payout is not performed. In other cases, that is, when the “cherry” symbol of the left reel 471 does not stop on the active line and the same symbols as the left, middle, and right are not aligned on the active line, no medal payout is performed.

  Here, FIG. 36 (end view taken along line AA in FIG. 28) shows a mounting structure using screw holes 222a and 222b of the fixed base plate 211 with respect to the back plate 11c. As shown in FIG. 36, the protruding portion 229 provided on the back surface of the bottom plate portion 213 is inserted into the positioning hole portion 16 provided in the back plate 11c, whereby the fixed base plate 211 is positioned with respect to the back plate 11c. Is done. Then, the screw 223 is inserted into the insertion hole 19 from the back side of the back plate 11c of the housing 11, and the screw 223 is screwed into the screw holes 222a and 222b, whereby the fixed base plate 211 is fixed to the back plate 11c. The

  On the other hand, in the movable base plate 212, side plate portions 242 and 243 are formed on the long side portion (upper and lower end portions in FIG. 32) of the bottom plate portion 241, and the side plate is provided on one side of the short side portion (left side in FIG. 32). A stepped portion 244 is formed so as to be continuous with the portions 242 and 243. These side plate portions 242 and 243 and the stepped portion 244 have a height that matches the main controller 201. Return portions 242a and 243a bent inwardly are provided at a plurality of locations (six locations in the present embodiment) at the front end portions of the side plate portions 242 and 243, respectively. A right end portion of the bottom plate portion 241 serves as a board mounting opening 245 for slidingly mounting the main control device 201. In this case, the main controller 201 is mounted from a board mounting port 245 and is slid until it contacts the step 244 so that the main controller 201 is mounted at a predetermined position on the movable base plate 212.

  The stepped portion 244 includes an opening 246 that opens in the sliding direction of the main control device 201, a locking hole 247 formed on the upper surface (upper surface of the bottom plate 241), and a locking hole. A pair of through holes 248 formed so as to sandwich 247 is provided. An upper surface portion of the stepped portion 244 provided with the locking hole portion 247 and the through hole 248 serves as a pasting surface of a seal seal S described later, and a surrounding frame 331 is formed so as to surround the pasting surface.

  Further, a rotation shaft portion 249 is provided at the left end portion of the movable base plate 212, and a shaft hole 249a is formed in the rotation shaft portion 249. In such a configuration, the shaft support portion 216 of the fixed base plate 211 and the rotation shaft portion 249 of the movable base plate 212 are aligned, and in this state, the shaft holes 216a and 249a of the shaft support portion 216 and the rotation shaft portion 249 are struts. The pin 217 is inserted. Thereby, the movable base plate 212 is rotatably supported with respect to the fixed base plate 211.

  The hole diameter (design dimension) of the shaft hole 216 a of the shaft support 216 is slightly smaller than the outer diameter of the support pin 217, and the hole diameter of the shaft hole 249 a of the rotating shaft 249 is slightly larger than the outer diameter of the support pin 217. When the support pin 217 is inserted, the support pin 217 is press-fitted into the shaft hole 216 a of the shaft support 216. At this time, the head of the support pin 217 is in a state of being flush with the shaft support 216 or in a state of being immersed in the shaft hole 216a, and the support pin 217 cannot be removed. Therefore, the movable base plate 212 can be rotated with respect to the fixed base plate 211, but cannot be separated (disconnected). However, contrary to the above configuration, the hole diameter (design dimension) of the shaft hole 249a of the rotation shaft portion 249 is slightly smaller than the outer diameter of the support pin 217, so that the support pin 217 is the shaft hole of the rotation shaft portion 249. The structure which press-fits to 249a may be sufficient. What is necessary is just to comprise the movable base plate 212 so that the movable base plate 212 can rotate with respect to the fixed base plate 211 and cannot be separated (cannot be disconnected).

  On the bottom plate portion 241, a plurality (four in this embodiment) of seal coupling portions 251 constituting the first sealing portion are erected so as to be aligned in a vertical row. The seal coupling portion 251 has a cylindrical shape whose bottom is closed by the bottom plate portion 241, and is open only on the front side of the figure.

On the side of the chip, identification information such as the manufacturer and product number, unique information, and the like are printed. The main substrate 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 part that can accommodate relatively tall electronic components and the like on the main board 273, and a step part 281 that is one step lower is formed at the peripheral part. A plurality of connector insertion holes 282 for inserting the input / output connectors 275 on the main board 273 are formed in the stepped portion 281. Reference numeral 283 denotes an opening communicating with the inspection connector 276 on the main board 273. Although illustration is omitted, a large number of air holes are formed in the ceiling portion of the front case body 271 and the like.

  Further, in the long side portion of the front case body 271, a ridge portion 285 extending linearly along the side wall of the front case body 271 is provided at each of the upper and lower edges, and a plurality of ridge portions 285 are provided inside the ridge portion 285. The long holes 286 are provided in a line at a predetermined interval.

  A vertical rectangular cutout hole 290 is provided at the left end of the front case body 271 (on the left side of the main board housing part). The cutout hole 290 includes a plurality of first sealing parts. The four seal coupling portions 291 (in this embodiment) are provided so as to be aligned in a vertical row. The peripheral configuration is shown enlarged in FIG. The seal coupling portion 291 has a cylindrical shape, and is connected to the front case body 271 by connecting portions 292 on both left and right sides. By cutting the connecting portion 292, the seal coupling portion 291 can be excised from the front case body 271. Similarly, a plurality of (two in the present embodiment) sealing coupling portions 293 constituting the second sealing portion are provided in the notched square hole portion 290 so as to sandwich the plurality of sealing coupling portions 291. The seal coupling 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 coupling portion 293 can be excised from the front case body 271.

  In such a case, since the seal coupling portions 291 and 293 constituting the first and second seal portions are provided in the notched square hole portions 290 formed in the front case body 271, the seal coupling portions 291 and 293 are projected to the side of the substrate case. Unlike the conventional general configuration in which the sealing portion is provided in the sealing portion, there is no inconvenience that the sealing coupling portions 291 and 293 protrude to the side and become obstructive. 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 controller 201 is handled alone.

  The left end portion of the front case body 271 is a leading portion when the main controller 201 is slidably mounted on the movable base plate 212, and a locking claw portion 295 is provided at the tip portion, and the locking claw A pair of screw hole portions 296 is provided so as to sandwich the portion 295. When the main controller 201 is mounted on the movable base plate 212, the locking claw portion 295 is locked in the locking hole portion 247 provided in the movable base plate 212. Further, the screw holes 296 are aligned with the through holes 248 provided in the movable base plate 212, and in this state, the machine screws 297 are screwed into the through holes 248 and the screw holes 296.

  On the left side of the cutout corner hole 290 of the front case body 271, an enclosing frame 332 that defines and forms a sticking surface of the seal seal S is formed. When the main controller 201 is mounted on the movable base plate 212, the enclosure frame 332 of the front case body 271 and the enclosure frame 331 formed on the movable base plate 212 are integrated to form a rectangular frame-like enclosure as a whole. A frame is formed.

  Returning to the description of FIG. 33, a plurality of (two in this embodiment) seal coupling portions 301 constituting the third seal portion are provided at the right end portion of the front case body 271. The seal coupling portion 301 has a cylindrical shape and is connected to the front case body 271 by a connecting portion 302. By cutting the connecting portion 302, the seal coupling portion 301 can be excised from the front case body 271.

  Further, a key attachment fitting 305 is attached and fixed to the right end portion of the front case body 271. The base portion of the key attachment bracket 305 is fixed to the front case body 271 with a fixing tool such as a screw (not shown). The tip of the key fitting 305 is bent obliquely outward, and a key insertion hole 305a is formed in the bent portion (see FIG. 36 and the like).

  On the other hand, in the back case body 272, a plurality of hook portions 312 standing in the substrate height direction and having tip portions formed in an L shape are provided at predetermined intervals on both upper and lower sides of the figure with the bottom plate portion 311 interposed therebetween. It has been. The hook portions 312 are provided at the same interval as the long holes 286 of the front case body 271, and both 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. Assembling of is to be performed.

  FIG. 37 (end view taken along line BB in FIG. 28) shows an assembly structure of the front case body 271 and the back case body 272. As shown in FIG. 37, the hooking portion 312 of the back case body 272 is inserted into the long hole 286 of the front case body 271, and in this state, the hooking portion 312 is formed in the long hole 286 on the front case body 271 side. Locked to the locking portion 286a. Accordingly, the front case body 271 is held without being lifted with respect to the back case body 272. Incidentally, FIG. 37 illustrates a state in which the main controller 201 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. Assuming that the front case body 271 is not assembled to the front case body 271, the front case body 271 is once slid rightward in FIG. 37 and then lifted upward to separate the front case body 271 from the back case body 272 (FIG. 37). The front case body 271 is moved along the arrow P in the middle).

  In the movable base plate 212, a return portion 212a is provided at the left end portion of FIG. 37, and this return portion 212a is below the shaft support portion 216 of the fixed base plate 211 (actually, the hole portion 216b shown in FIG. 32). It is configured to enter. Therefore, even if the support pin 217 is cut off in the middle or the support pin 217 is pulled out, the movable base plate 212 is not lifted with respect to the fixed base plate 211 by itself.

  Returning to FIG. 33 again, a pair of upper and lower extension portions 314a and 314b are provided at the left end portion of the back case body 272 so as to extend leftward from the bottom plate portion 311. Each of the portions 314a and 314b is provided with a seal coupling portion 315 constituting the second seal portion. The seal coupling portion 315 has a cylindrical shape whose bottom is closed with the same surface as the bottom plate portion 311 and is open only on the front side of the figure. The extending portions 314a and 314b are provided separately in the vertical direction, and the space between the extending portions 314a and 314b is for avoiding interference with the plurality of seal coupling portions 251 provided on the movable base plate 212. It is an empty space.

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

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

  Here, a sealing structure for suppressing unauthorized removal of the main control device 201 and the pedestal device 210 will be described. In the present embodiment, three types of sealing portions each having a different sealing structure are provided, and for convenience, they will be described as a first sealing portion, a second sealing portion, and a third sealing portion in order. FIG. 38 corresponds to the end view taken along the line CC of FIG. 28 and shows a cross-sectional structure of the first sealing portion. FIG. 39 is an end view taken along the line DD of FIG. 28, and shows a cross-sectional structure of the second sealing portion. FIG. 40 is an end view taken along line EE of FIG. 28 and shows a cross-sectional structure of the third sealing portion.

  First, the configuration of the first sealing portion will be described with reference to FIG. In FIG. 38, (a) shows a state before sealing, (b) shows a sealed state, and (c) shows a released state. The first sealing portion can be in a sealed state by the combination of 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. For convenience, the former is referred to as “insertion”. The description will proceed by rephrasing the “side coupling portion 291” and the latter as “receiving side coupling portion 251”.

  As shown in FIG. 38 (a), the insertion side coupling portion 291 of the front case body 271 is formed with a hole portion 291a (referred to as an upper hole portion for the sake of convenience) penetrating in the vertical direction. The receiving-side coupling portion 251 of the plate 212 is formed with a hole portion 251a (referred to as a lower hole portion for convenience) that communicates coaxially with the upper hole portion 291a. A stepped portion 291b is provided at the inlet portion of the upper hole portion 291a, and an enlarged diameter portion 251b having a diameter larger than that of the upper hole portion 291a is provided at the inlet portion of the lower hole portion 251a.

  Reference numerals 251c and 291c are semicircular return portions respectively provided in the receiving side coupling portion 251 and the insertion side coupling portion 291 (the return portion 251c is forward of the main controller 201 in the sliding direction, and the return portion 291c is The connecting portions 251 and 291 abut on the return portions 251c and 291c. The opposing joint surfaces of the coupling portions 251 and 291 are hidden by the return portions 251c and 291c.

  In addition, the connection part 292 which connects the insertion side coupling | bond part 291 is carrying out the substantially inverted trapezoid shape so that an upper side becomes long and a lower side becomes short, as shown with a hidden line (dotted line) in a figure. In this case, in particular, the end of the connecting portion 292 opposite to the insertion-side coupling portion 291 is formed in an obliquely tapered shape so as to incline outward toward the upper side.

  When carrying out the sealing process, as shown in FIG. 38B, each hole 291a, 251a of the insertion side coupling part 291 and the receiving side coupling part 251 is made of, for example, a synthetic resin and has a substantially hollow cylindrical shape. The sealing pin member 321 is inserted. As shown in FIG. 35, the sealing pin member 321 has a hollow cylindrical portion 321a, a flange-shaped head portion 321b, and two locking claw portions 321c that are provided at the cylindrical portion 321a and can be elastically deformed, for example. In a normal state, the locking claw portion 321c protrudes outward from the outer periphery of the cylindrical portion 321a, and the locking claw portion 321c can be immersed in the cylindrical portion 321a by applying an external force. Yes. Identification information (for example, an identification code) for each main control device 201 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 inserted until the head portion 321b hits the step portion 291b at the upper hole entrance. At this time, when the locking claw portion 321c of the sealing pin member 321 reaches the enlarged diameter portion 251b of the lower hole portion 251a, the locking claw portion 321c rises, and the rear end surface of the locking claw portion 321c is connected to the insertion side. The front end surface of the portion 291 is locked. Thereby, the sealing of the first sealing part is completed, and the sealing pin member 321 after the sealing is prevented from falling off.

  When the seal of the first seal portion is to be released in the event of a malfunction or inspection of the main controller 201, as shown in FIG. 38 (c), the insertion side coupling portion 291 and the front case body 271 are connected. The connecting portion 292 to be connected is cut with a tool such as a nipper. Since only the front end portion of the sealing pin member 321 is inserted into the receiving side coupling portion 251, and these members 251 and 321 are not in any locked state, the insertion side coupling portion is cut by cutting the connecting portion 292. 291 and the sealing pin member 321 can be easily removed from the front case body 271. At this time, as described with reference to FIG. 38A, the connecting portion 292 has a substantially inverted trapezoidal shape in which the upper side is long and the lower side is short, so that it is easy to insert a tool such as a nipper. In addition, since the end of the connecting portion 292 opposite to the insertion side coupling portion 291 is formed in an obliquely tapered shape so as to incline outward toward the upper side, after the connecting portion 292 is cut, the insertion side The coupling portion 291 and the sealing pin member 321 are easily pulled upward.

  The cut-out insertion side coupling portion 291 and the sealing pin member 321 can be easily separated by pressing the locking claw portion 321c of the sealing pin member 321 with a finger or a tool and elastically deforming it. The separated sealing pin member 321 is not deformed or broken at all, and the same sealing pin member 321 is used for the next sealing.

  As described above, the identification information for each main control device 201 is attached to the head 321b of the sealing pin member 321. Therefore, after the sealing process is performed again by the reuse of the sealing pin member 321, the identification information is displayed. By checking, it can be confirmed whether or not the sealing process has been performed in accordance with the regular procedure.

  When the seal of the first seal part is released, the part to be cut (destructed) is only the connecting part 292 on the front case body 271 side, and the movable base plate 212 is not destroyed anywhere in this case. 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. Accordingly, even when the main control device 201 is replaced, the movable base plate 212 (that is, the pedestal device 210) can be reused as it is.

  In the first sealing portion, which of the four sealing locations is used is determined in advance. For example, sealing is performed one by one in order from the top in FIG. The sealing history remains at the sealed portion where the cutting process (destructive process) has been performed after sealing, and it is possible to easily confirm how many times the sealing process has been performed in the past. The fact that the sealing process has been performed at each sealing location is recorded on a sealing record slip affixed to the surface portion of the front case body 271 and the like. For example, on the sealing record slip, the date of execution of the sealing process, the name of the sealing operator, and the like are recorded for each sealing location. This sealing record slip may be a record in which a sealing process record is similarly left for a second sealing portion and a third sealing portion to be described later.

  Next, the structure of a 2nd sealing part is demonstrated based on FIG. The second sealing portion can be in a sealed state by the combination of 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 description will proceed by rephrasing the “side coupling portion 293” and the latter as “receiving side coupling portion 315”.

  As shown in FIG. 39, the insertion side coupling portion 293 of the front case body 271 is formed with a hole portion 293a (referred to as an upper hole portion for convenience) penetrating in the vertical direction. The receiving side coupling portion 315 is formed with a hole portion 315a (referred to as a lower hole portion for convenience) that communicates coaxially with the upper hole portion 293a. The upper hole portion 293a is formed with a large-diameter portion for accommodating a head of a sealing screw 323, which will be described later, and a small-diameter portion having a smaller diameter. A female screw part is formed in the lower hole part 315a. And the sealing screw 323 is screwed in each hole 293a, 315a of the insertion side coupling | bond part 293 and the receiving side coupling | bond part 315, and the sealing of a 2nd sealing part is completed. The sealing screw 323 is configured by a so-called breaking screw having a breakable portion (reduced diameter portion) that is easily broken at an intermediate portion, and when the screw 323 is screwed with a tightening tool such as a driver, a predetermined torque or more is applied. The rupture portion is broken. 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 seal of the second sealing part, the connecting part 294 that connects the insertion side connecting part 293 and the front case body 271 is cut with a tool such as a nipper (X1 part in the figure), and the receiving side connecting part The bottom part of 315 is cut | disconnected with tools, such as a nipper, (X2 part of a figure). That is, a vertical cutting process and a horizontal cutting process orthogonal to the vertical cutting process are performed. Thereby, the sealing screw 323 can be separated from the case bodies 271 and 272, and the sealing of the second sealing portion can be released.

  Next, the structure of a 3rd sealing part is demonstrated based on FIG. The third sealing portion can be brought into a sealed state by the combination of 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 will proceed by rephrasing the “side coupling portion 301” and the latter as “receiving side coupling portion 317”.

  As shown in FIG. 40, the insertion side coupling portion 301 of the front case body 271 has a hole portion 301a (referred to as an upper hole portion for convenience) penetrating in the vertical direction. The receiving side coupling portion 317 is formed with a hole portion 317a (referred to as a lower hole portion for convenience) that communicates coaxially with the upper hole portion 301a. The upper hole portion 301a is formed with a large-diameter portion for accommodating a head of a sealing screw 325, which will be described later, and a small-diameter portion having a smaller diameter. A female screw portion is formed in the lower hole portion 317a. And the sealing screw 325 is screwed in each hole 301a, 317a of the insertion side coupling | bond part 301 and the receiving side coupling | bond part 317, and the sealing of a 3rd sealing part is completed. The sealing screw 325 is a so-called one-way screw (also referred to as a one-way screw) that can be screwed with a tightening tool such as a screwdriver in the tightening direction but cannot be loosened in the loosening direction. Once 325 is screwed into the holes 301a, 317a, it is impossible to loosen the screw 325 thereafter.

  To release the seal of the third sealing portion, a connecting portion 302 that connects the insertion side connecting portion 301 and the front case body 271, 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 portion in the figure). Thereby, the sealing screw 325 can be separated from the case bodies 271 and 272, and the sealing of the third sealing portion can be released.

  In the above description, it has been described that both the second sealing portion and the third sealing portion are sealed. However, in actuality, only one of these sealing portions is sealed. For example, when the slot machine 10 is manufactured, the second sealing portion is sealed when the main board 273 is accommodated in the board box (case bodies 271 and 272). After that, when the main controller 201 is recovered for inspection or the like, the second sealing portion is opened and the third sealing portion is sealed after inspection or the like.

  On the other hand, as shown in FIG. 29 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 seal case surrounded by the surrounding frames 331 and 332 of the front case body 271 are connected to the movable base plate 212. A rectangular seal seal S is pasted so as to straddle the case body 271. When the seal seal S is once applied and then peeled off, the adhesive is peeled off from the seal label and cannot be applied again. When the seal seal S is peeled off, the trace remains, so the movable base It can be confirmed whether or not the main controller 201 has been removed from the plate 212. In a state where the main controller 201 is coupled to the movable base plate 212, the locking hole portion 247 and the through hole 248 formed in the movable base plate 212, the locking claw portion 295 and the screw formed in the front case body 271. The holes 296 are in a combined state, and they are covered with the seal seal S.

  As described above, the seal seal S has a configuration that cannot be re-applied. However, there is a fraudulent act in which another seal member (sticking piece) is pasted after the seal seal S is peeled off, and this fraudulent act is suppressed. Therefore, it is considered that one measure is to suppress the act of peeling off the seal seal S. Therefore, in the present embodiment, as a countermeasure against unauthorized peeling of the seal seal S, the seal application 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 surrounding frames 331 and 331 are further separated. The vicinity of the base end portion of 332, that is, the vicinity of the base portion (peripheral portion of the sticking surface of the seal) is formed in a curved shape. Specifically, the sealing surface is curved by forming a tapered surface in accordance with the long side portion of the seal seal S.

  When the seal seal S is affixed to the seal application surface, the peripheral portion of the seal seal S enters the curved portion of the seal application surface, and it becomes difficult to hook the peripheral portion of the seal seal S with a nail or the like. Therefore, the deterrent effect with respect to illegally peeling off the seal seal S is obtained. In the configuration of the present embodiment, the seal sticking surface surrounded by the surrounding frames 331 and 332 substantially coincides with the size of the seal seal S. There is no gap. Therefore, it is even more difficult to hook the peripheral edge of the seal seal S with a nail or the like and peel it off.

  As shown in FIG. 41, in a state where the main control device 201 is mounted on the pedestal device 210, the key mounting bracket 261 provided on the movable base plate 212 and the key mounting bracket 316 provided on the back case body 272 of the main control device 201. And a key member K1 such as a padlock is attached through the key insertion portions 261a and 316a of the respective key fittings 261 and 316. Further, when the fixed base plate 211 and the movable base plate 212 are overlapped, the key mounting bracket 219 provided on the fixed base plate 211 and the key mounting bracket 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 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.

  In 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. Even if the key member K2 is removed, the main controller 201 cannot be removed from the movable base plate 212 unless the key member K1 is removed. Therefore, the main controller 201 cannot be removed unless it is the owner of the properly managed unlocking key.

  Each of the sealing portions described above is originally configured to be capable of being cut (destroyed), and the main purpose is to leave an opening history. Therefore, it is possible to prevent illegal acts such as taking away (stealing) the main control device 201. Although the effect cannot be exhibited, the above-described configuration in which the key members K1 and K2 are attached can exert a deterrent effect against the removal of the main control device 201 (can be an anti-theft measure for the main control device 201).

  Note that the tip ends of the key fittings 219 and 305 are inclined so as to escape from the main controller 201. Thereby, even if the key member K2 is attached to the side of the front case body 271, the key member K2 can be mounted without being obstructed by the front case body 271 or the like.

  When the main board unit 200 is attached to the back plate 11c of the housing 11, the protrusion 229 provided on the back surface of the bottom plate portion 213 of the fixed base plate 211 is inserted into the positioning hole 16 provided in the back plate 11c. Thereby, the fixed base plate 211 is positioned with respect to the back plate 11c. Then, the screw 223 inserted into the insertion hole 19 from the back side of the back plate 11c is screwed into the screw holes 222a and 222b of the fixed base plate 211. Furthermore, as shown in FIG. 9, the screw 231 is inserted into the insertion holes 17 and 18 from the back surface side of the back plate 11c. The main board unit 200 is fixed to the back plate 11c by screwing the screws 231 into the screw holes 227a and 228a formed in the boss parts 227 and 228 of the attachment parts 225 and 226. The reel unit 400 is mounted on the housing 11 after the main board unit 200 is attached.

  When the main board unit 200 and the reel unit 400 are attached to the housing 11, the upper back surface portion 431 of the base frame 401 is positioned in front of the main board unit 200. As described above, the opening 427 has a horizontally long rectangular shape and is formed in substantially the same shape as the main substrate unit 200. The dimensions of the long and short sides of the opening 427 are determined according to the dimensions of the long and short sides of the main board unit 200. Here, the lengths of the long side portion and the short side portion of the opening 427 will be described with reference to FIG. 42 shows a front view of the main board unit 200, and the periphery of the opening 427 is indicated by a two-dot chain line.

  As shown in FIG. 42, the movable base plate 212 of the main board unit 200 and the rotating front end side (right side portion in FIG. 42) of the main controller 201 mounted on the movable base plate 212 to the left side portion of the opening 427 are shown. When the dimension (the longest dimension of the portion that can move to the front side through the opening 427) is M1, the dimension M2 of the long side portion of the opening 427 is larger than the dimension M1 (M1 <M2).

  In the short side portion of the main substrate unit 200, the dimension of the short side portion of the movable base plate 212 is N1, and the dimension of the short side portion of the fixed base plate 211 is N3. The main controller 201 is mounted on the inner side of the side plate portions 242 and 243 formed at the upper and lower ends of the movable base plate 212, and therefore the dimension of the short side portion of the main controller 201 is smaller than N1. When the dimension of the short side portion of the opening 427 is N2, N2 is larger than N1 and smaller than N3 (N1 <N2 <N3).

  By determining the long side dimension M2 and the short side dimension N2 of the opening 427 as described above, the main controller 201 and the movable base plate 212 that overlap the opening 427 in the front-rear direction (in FIG. 42). The main controller 201 and the movable base plate 212 located inside the opening 427 can move to the near side through the opening 427. Further, most of the attachment portions 225 and 226 of the fixed base plate 211 do not overlap with the opening portion 427 in the front-rear direction, but overlap with the surrounding portion 428 of the upper back surface portion 431 in the front-rear direction. As a result, if the fixed base plate 211 is moved to the front side through the opening 427, the attachment portions 225 and 226 interfere with the surrounding portion 428, and it is difficult to move the front side.

  Here, with the main board unit 200 and the reel unit 400 attached to the housing 11, the main control device 201 is moved to the near side and the main control device 201 is detached from the base device 210 with reference to FIG. explain. 43A shows a state in which the movable base plate 212 is superimposed on the fixed base plate 211 (that is, a normal use state), and FIG. 43B shows a movable base plate with respect to the fixed base plate 211. FIG. 4C shows a state in which the main control device 201 is slid from the movable base plate 212 while the movable base plate 212 is rotated. Note that the shape of the base frame 401 is simplified for convenience. In FIG. 43, 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 is in the main controller 201 (actually, the front case body 271). It is latched on the top surface. Although not shown 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 cannot rotate with respect to the fixed base plate 211. At this time, the surface of the main controller 201 faces the front side of the slot machine 10, and the surface of the main substrate, that is, the mounting surface of the IC chip or the like, is provided through the opening 427 of the Lee unit 400 (base frame 401). And is visible from the front. In this case, fraud with respect to the main controller 201 (such as fraud on the substrate surface) can be easily confirmed.

  When the movable base plate 212 is rotated as shown in (b), the key member (at least the key member K2 in FIG. 41) 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 the support pin 217 as a rotation center, and the rotating front end side of the main controller 201 is moved to the front side through the opening 427 together with the movable base plate 212. In such a state, it is possible to visually recognize the back side of the main control device 201 (that is, the back side of the main board 273), and it is possible to check whether there are any abnormalities or frauds in various electronic components, electrical wiring, and the like. At this time, the main control device 201 is located in front of the back plate 11c of the housing 11, and when the main control device 201 is rotated forward together with the movable base plate 212, the main control device 201 is provided. Fraud confirmation etc. becomes easier.

  When the movable base plate 212 and the main control device 201 are rotated with respect to the fixed base plate 211 as shown in (b), the main control device 201 is viewed from an oblique side from a state of being viewed from the front side. Transition to the state. Therefore, even information that is difficult to see from the front of the main control device 201, that is, information attached to an upright surface portion that is substantially perpendicular to the substrate surface of the main substrate 273, is easily visible by the rotation of the movable base plate 212. It can be. For example, in the vertical IC chip 274 mounted on the main substrate 273, information such as manufacturer and product number printed on the side surface of the chip can be easily visually confirmed.

  Incidentally, in the actual configuration of the slot machine 10, as shown in FIG. 4 and the like, since no device or the like is installed in the front region of the opening 427 of the base frame 401, the front of the movable base plate 212. There is no hindrance to the pivoting movement to the side. Even if a device or a mechanism that protrudes rearward of the slot machine is provided on the back surface of the front door 12, the front space of the main control device 201 is opened as the front door 12 is opened, and the movable base plate 212 is rotated. Will not cause any problems.

  Further, when the main controller 201 shown in FIG. 43 (c) slides, the key member (key member K1 in FIG. 41) is removed and the first sealing portion (the seal between the movable base plate 212 and the front case body 271) is removed. ) Is opened. Further, locking of the locking claw 295 provided at the left end of the front case body 271 and screw fixing at the screw hole 296 are released. In this state, the main controller 201 is slid on the movable base plate 212. As a result, the main controller 201 can be detached from the rotating tip end side of the movable base plate 212 (the substrate mounting opening 245 in FIG. 32).

  In addition, the enclosing portion 428 of the upper back surface portion 431 and the mounting portions 225 and 226 of the fixed base plate 211 overlap with each other in the front-back direction. Therefore, even if the screw 231 or the like attached to the housing 11 is removed from the fixed base plate 211, if the fixed base plate 211 is moved to the front side through the opening 427, the mounting portions 225 and 226 are Interference with the surrounding portion 428 makes it difficult to move forward. Thereby, it is possible to suppress an illegal act such as taking away the main control device 201 together with the pedestal device 210.

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

  The main control device 201 is equipped with a microcomputer centering on a CPU 701 which is arithmetic processing means. In addition to the power supply device 711 provided in the power supply box 100, the CPU 701 is connected to a clock circuit 704 that outputs a rectangular wave having a predetermined frequency, an input / output port 705, and the like via an internal bus. The main control device 201 functions as a main board built in the slot machine 10.

  On the input side of the main controller 201, there are a start detection sensor 721 that detects the operation of the start switch 45, stop detection sensors 722, 723, and 724 that individually detect the operations of the stop switches 52 to 54, and the medal insertion device 41. An inserted medal detection sensor 725 for detecting inserted medals, bet detection sensors 726 to 728 for individually detecting operations of the bet switches 42 to 44, an adjustment detection sensor 729 for detecting an operation of the adjustment switch 56, and reels 471 to 471. A reel index sensor 731 that individually detects the rotational position (origin position) of 473, a payout detection sensor 732 that detects medals paid out from the hopper device 110, and a reset detection sensor that detects an operation of the reset switch 102 provided in the power supply box 100 733, setting key insertion hole 103 Setting key is various sensors such as setting the key detection sensor 734 for detecting are connected to be inserted, signals from the various sensors are outputted to the CPU701 through the input and output ports 705.

  The inserted medal detection sensor 75a is actually composed of a plurality of sensors. That is, the storage passage 92 from the medal insertion device 41 to the hopper device 110 is configured so that medals can pass in one row. The storage passage 92 is provided with a first sensor, and the second sensor and the third sensor are close to each other on the downstream side more than the width of the medal. The inserted medal detection sensor 725 is constituted by each of the first to third sensors. The main controller 201 monitors the time from the first sensor to the second sensor. If the elapsed time exceeds a predetermined time, the main control device 201 regards that there is a medal clogging or fraud and makes an error. If an error occurs, an error notification is performed and an operation by the player until the error is canceled is invalidated. The main controller 201 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. Only when the third sensor is turned on, 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, it is determined that the medal has been normally taken in. Otherwise, an error is assumed. The reason for this is to prevent a fraud in which a medal is reciprocated near the inserted medal detection sensor 725 and misidentified as a medal inserted in addition to the clogging of the medal in the storage passage 92.

  Further, a power failure monitoring circuit 711 b provided in the power supply device 711 is connected to the input side of the main control device 201 via the input / output port 705. The power supply device 711 includes a power supply unit 711 a that supplies driving power to the electronic devices of the slot machine 10 including the main control device 201, the power failure monitoring circuit 711 b described above, and the like.

  The power failure monitoring circuit 711b is for monitoring the power shutoff state and generating a power failure signal not only at the time of a power failure but also at the time of power failure by a power switch provided in the power supply box. Therefore, the power failure monitoring circuit 711b monitors the stabilized drive voltage of 12 VDC in this example output from the power supply unit 711a, and determines that the power supply is shut off when the drive voltage drops to, for example, less than 10 volts. Is configured to output a power failure signal. The power failure signal is supplied to each of the CPU 701 and the input / output port 705, and the CPU 701 recognizes this power failure signal and executes a power failure process.

  Even when the output voltage drops below 22 volts, the power supply unit 711a is configured to output a stabilized voltage of 5 volts that is used as a drive voltage in a control system such as the main controller 201. As the time during which the stabilization voltage is output, sufficient time is secured for executing the power failure process by the main control device 201.

  On the output side of the main controller 201, the remaining number display unit 61, the game number display unit 62, the acquired number display unit 63, the stepping motors 475 for rotating the reels 471 to 473, and the like are provided in the selector 91. A medal path switching solenoid, a hopper device 110, a display control device 601, an external concentration terminal board 740 capable of transmitting information to a hall management device (not shown), and the like are connected via an input / output port 705.

  The display control device 601 is a control device for driving various lamps such as the central lamp unit 26 and the side lamp unit 28, various speakers such as the speakers 603 and 604, and the liquid crystal display device 600. A substrate on which a CPU, a ROM, a RAM, and the like are integrated is provided. Then, after receiving a signal from the main control device 201, the display control device 601 independently controls various lamps, various speakers, and the liquid crystal display device 600. Therefore, the display control device 601 is a sub-board that performs auxiliary control in relation to the main control device 201 that is a main board that manages and manages games. In other words, a sub-board is provided for voice, lamp, and display related to indirect games, thereby reducing the burden on the main board. In addition, it is good also as a structure which the display control apparatus 601 controls the various display parts 61-63.

  The CPU 701 described above stores various control programs executed by the CPU 701 and ROM 702 storing fixed value data, and temporarily stores various data when executing the control programs stored in the ROM 702. In addition to the RAM 703 for securing the area, although not shown, various processing circuits necessary for the slot machine 10 such as a timer circuit and a data transmission / reception circuit such as an interrupt circuit as well known, and a credit counter for counting the number of credits. Various counters such as are built-in. The ROM 702 and the RAM 703 constitute a main memory as storage means, and various programs are stored in the ROM 702 described above as part of the control program.

  The RAM 703 has a configuration in which a backup voltage is supplied from the power supply device 711 even after the power to the slot machine 10 is shut off, and data can be held (backed up). The RAM 703 temporarily stores various data and the like. In addition to the memory and area for storing, a backup area is provided.

  The backup area includes a stack pointer, each register, and I when power is shut down due to the occurrence of a power failure or the like (including power shut-down by operating a power switch provided in the power box 100; the same applies hereinafter). This is an area for storing values such as / O, and when the power failure is resolved (including power-on by operating the power switch; the same applies hereinafter), the state of the slot machine 10 is based on the backup area information. It is possible to return to the state before the power was shut off. Writing to the backup area is executed when the power is cut off by the power failure process, and restoration of each value written to the backup area is executed in the main process when the power is turned on. Note that a power failure signal from the power failure monitoring circuit 711b is input to the NMI terminal (non-maskable interrupt terminal) of the CPU 701 when the power is interrupted due to the occurrence of a power failure or the like. NMI interrupt processing as flag generation processing is immediately executed.

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

  An opening 427 that allows the main control device 201 constituting the main board unit 200 and the movable base plate 212 of the pedestal device 210 to move to the near side is formed in the upper and rear surfaces 431 of the base frame 401 of the reel unit 400. On the other hand, when the fixed base plate 211 of the pedestal device 210 is removed from the back plate 11c of the housing 11 and passed through the opening 427, the mounting portions 225 and 226 that interfere with the surrounding portion 428 of the upper back surface portion 431 are provided. It was set as the structure provided. More specifically, the opening 427 is formed as a horizontally-long rectangular opening 427 having substantially the same shape as the main substrate unit 200, and the longest dimension of the opening 427 in the vertical and horizontal directions (the opening 427 in FIG. 42). Of the movable base plate 212 and the main controller 201 in the base device 210 of the main board unit 200 can be moved to the front side through the opening 427. Larger than the longest dimension in the vertical direction and the horizontal direction (the dimension M1 of the long side portion of the main controller 201 and the dimension N1 of the short side portion of the movable base plate 212 in FIG. 42) and the longest dimension of the opening portion 427 in the vertical direction. 42 (the dimension N2 of the short side of the opening 427 in FIG. 42) is the longest dimension in the vertical direction of the fixed base plate 211 of the base device 210 (the dimension of the short side of the fixed base plate 211 in FIG. 3) it was smaller than. As a result, by moving the main control device 201 to the front side, the hall manager of the game hall can check the main control device 201 relatively close, so that the main control device 201 is cheated. This makes it easy to check whether or not there is any problem. On the other hand, if it is attempted to take out the fixed base plate 211 removed from the housing 11 through the opening 427, the mounting portions 225 and 226 interfere with the surrounding portion 428, making it difficult to take out. As a result, removal of the pedestal device 210 from the housing 11 and further removal of the main control device 201 together with the pedestal device 210 or replacement with a non-genuine main control device 201 (main board 273) can be suppressed. Can do.

  Further, by providing the base frame 401 with the opening 427, the above-described main controller 201 is allowed to move to the near side, and an illegal act (specifically, an operation performed by removing the base device 210 from the housing 11) It is not necessary to newly provide a member for suppressing the main controller 201 together with the pedestal device 210. Further, in order to perform an illegal act such as taking the main control device 201 together with the pedestal device 210, it is necessary to remove the reel unit 400 (base frame 401) from the housing 11 once. In general, at game halls and the like, intruders in the halls are monitored by motion-sensitive monitoring devices such as infrared sensors at night when business is closed. It is difficult to carry out fraud such as taking away the control device 201 together with the pedestal device 210 or replacing it with a main control device 201 (main board 273) which is not a regular product. On the other hand, there is a possibility of fraud such as taking away the main controller 201 together with the pedestal device 210 because it is not monitored as described above during operation. It can be required and fraud can be suppressed.

  In the base frame 401, the opening 427 is provided in the upper and back surfaces 431 of the back frame 414, so that the main control device 201 moved to the front side is behind the reel device 406 and the visibility is lowered. Can be prevented. That is, when the reels 471 to 473 are enlarged for the purpose of improving the visibility of the symbols and the game playability, the main controller 201 moved to the front side is positioned below the reel device 406, so that it is hidden behind the reel device 406. Although it may be hidden and its visibility may be reduced, this configuration can eliminate such inconvenience.

  Further, the back frame portion 414 of the base frame 401 has a step shape having a lower back surface portion 432 adjacent to the back plate 11c of the housing 11 and an upper back surface portion 431 spaced from the back plate 11c of the housing 11, and the upper back surface By providing the opening portion 427 in the portion 431, the main board unit 200 can be easily disposed behind the upper back surface portion 431. Furthermore, since the gap dimension (dimension D1 in FIG. 12) between the lower back surface portion 432 and the back plate 11c is made smaller than the thickness dimension (dimension D2 in FIG. 12) of the main board unit 200, the base device 210 is removed from the casing 11. The main control device 201 can be reliably prevented from being taken out of the casing 11 through the base frame 401 and the back plate 11c of the casing 11 together with the base device 210.

  Further, since the reel unit 400 is an exchange unit, when changing the model of the gaming machine, the main controller 201 can be taken out together with the base device 210 by removing the reel unit 400 from the housing 11. Furthermore, since the model can be changed by exchanging the reel unit 400 and the main board unit 200, it is possible to reuse parts such as the casing 11 and the hopper device 110 that do not require replacement.

  In the housing 11 (base frame 401), no device or the like is provided in front of the upper back surface portion 431, so that movement of the main controller 201 to the near side is not hindered. Further, since the visual recognition of the main control device 201 moved to the near side is not hindered, the hall manager or the like can easily perform the confirmation work of the main control device 201.

  In the fixed base plate 211 of the pedestal device 210, the mounting portions 225 and 226 are provided on the bottom plate portion 213 so as to extend up and down from the mounting portion on which the movable base plate 212 is mounted. 428 and the attachment portions 225 and 226 can be in a positional relationship overlapping in the front-rear direction. As a result, when the main control device 201 is to be taken out together with the pedestal device 210, the attachment portions 225 and 226 interfere with the surrounding portion 428. Accordingly, it is possible to suppress an extraction action such as taking away the main control device 201 together with the base device 210.

  Further, in addition to the screw holes 222a and 222b of the fixed base plate 211, the mounting portions 225 and 226 are provided with boss portions 227 and 228 having screw holes 227a and 228a, and the screw holes 227a and 228a are also attached to the back plate 11c. This makes it difficult to remove the fixed base plate 211 from the back plate 11c.

  In the main board unit 200, the movable base plate 212 on which the main control device 201 is mounted can be rotated with respect to the fixed base plate 211. Therefore, when the movable base plate 212 is rotated, the back surface of the main control device 201 (main substrate back surface). Is released. Therefore, it is possible to confirm whether there are any abnormalities or frauds in various electronic components, electrical wiring, etc. on the back side. Further, since the substrate surface of the main controller 201 is tilted by the rotation of the movable base plate 212, the side information of the vertical element (IC chip 274) mounted on the main substrate 273 can be easily read, It is possible to confirm that the element is a genuine product. That is, it is possible to easily confirm fraud that is difficult to confirm from the front.

  By sliding the main control device 201 on the movable base plate 212 in a state in which the movable base plate 212 is rotated, the main control device 201 can be attached and detached from the rotating front end side of the movable base plate 212. Since it comprised, the main control apparatus 201 can be easily mounted | worn or detached in the state which pulled the rotation front-end | tip part of the movable base board 212 to the near side. Therefore, the workability at the time of inspection or replacement of the main controller 201 can be improved.

  Since the key member K2 is provided to restrict the rotation of the movable base plate 212 relative to the fixed base plate 211, the movable base plate 212 cannot be rotated unless the rotation restriction by the key member K2 is released. The main control device 201 cannot be detached. Therefore, inconveniences such as unauthorized removal of the main control device 201 can be suppressed.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above embodiment, the main board unit 200 is provided above the reel device 406 on the back plate 11c of the housing 11. However, the main board unit 200 may be provided below the reel device 406. good. In this case, in the back frame portion of the base frame 401, the upper back portion is formed so as to bulge rearward from the lower back portion, and an opening 427 is provided in the lower back portion. In this case, it is desirable that a prevention plate or the like for preventing the main board unit from being removed is provided below the lower back surface portion.

  (B) In the above embodiment, the main board unit 200 is configured to rotate the main control device 201 and move it to the near side, but this may be configured as follows. For example, a pedestal device 210 is provided in which a leg mechanism that can expand and contract is provided between the fixed base plate 211 and the movable base plate 212, and the movable base plate 212 moves to the near side by the expansion and contraction. Even in this case, the main controller 201 can move to the front side through the opening 427. As a result, as in the present embodiment, the hall manager or the like can confirm the main control device 201 relatively closely, and can facilitate confirmation work such as fraud. Also in this configuration, the fixed base plate 211 is provided with mounting portions 225 and 226 that extend from the mounting portion on which the movable base plate 212 is mounted, and it is difficult to pass the base device 210 through the opening 427. Therefore, it is possible to suppress an illegal act such as removing the pedestal device 210 from the casing 11 and taking away the main control device 201 together with the pedestal device 210.

  (C) In the above embodiment, in the pedestal device 210, the attachment portions 225 and 226 are used as interference portions that interfere with the surrounding portion 428 surrounding the opening portion 427 of the base frame 401, but other modifications may be made. In short, any configuration may be employed as long as the interference device is provided in the pedestal device 210 so as to extend from the opening 427 so that it is difficult to pass the pedestal device 210 through the opening 427. That is, in this case, the interference portion does not need to be an attachment portion, and attachment of the pedestal device 210 to the housing 11 is arbitrary. As the mounting portion of the pedestal device 210, it is preferable to use the bottom hole portions 222a and 222b of the fixed base plate 211 or to newly provide a mounting portion.

  (D) In the above embodiment, in order to fix the reel unit 400 to the housing 11 and seal the fixed state, a sealing wire is provided or a sealing seal is affixed to the lock fittings 156 and 157 in the locked state. However, other sealing means are described below. For example, the base frame 401 and the housing 11 are provided with a seal coupling portion that is sealed between them. Specifically, a hole for inserting the sealing pin is provided in the left side plate 11d of the housing 11, and a hole for inserting the sealing pin is provided in the reel unit 400 (base frame 401). When the reel unit 400 is fixed to the housing 11 by the fixing means (the hook metal 443 and the lock metal 156, 157), the hole provided in the left plate 11d and the hole provided in the reel unit 400 And are aligned. A sealing pin is inserted into the hole. That is, it is the same as the structure which seal-couples the base apparatus 210 and the main-control apparatus 201 in this Embodiment. Accordingly, in order to remove the reel unit 400 from the casing 11, it is necessary to release the fixing state of the fixing means, and further to release the seal by cutting the seal coupling portion or the like, leaving a history. Can do.

  (E) In the above embodiment, the main board unit 200 is fixed to the back plate 11c of the housing 11. However, the main board unit 200 may be in a state of floating from the back plate 11c. That is, the fixed base plate 211 is assembled to the left and right side plates 11 d and 11 e of the housing 11. In addition, even if it is the structure which floats the main board | substrate unit 200 from the backplate 11c, it makes it a requirement to provide between the backplate 11c and the upper back surface part 432. FIG.

  (F) In the above-described embodiment, the upper and rear surfaces 431 of the base frame 401 are provided with the opening 427 that allows the main control device 201 to move toward the near side while making the passage of the fixed base plate 211 difficult. However, this may be changed as follows. The base frame 401 is a frame on which only the reel device 406 is mounted, and a frame member that allows the main control device 201 to move forward in front of the main board unit 200 while making it difficult for the fixed base plate 211 to pass therethrough. The structure which provides may be sufficient. In this case, the frame member is fixed to the base frame 401 or fixed to the housing 11.

  (G) In the above-described embodiment, the main control device 201 allows the upper and rear surfaces 431 of the base frame 401 to move with respect to the configuration in which the main control device 201 moves to the near side by the rotation mechanism of the pedestal device 210, and the pedestal device. Although the opening 427 that makes it difficult to pass a part of 210 is provided, the present invention can also be applied to a gaming machine having a configuration in which the main control device 201 cannot move forward. That is, even if the base device 210 is configured to be unrotatable from the present embodiment, the surface of the main substrate 273 can be confirmed through the opening 427. On the other hand, the opening 427 makes it difficult for a part of the pedestal device 210 to pass, and therefore, it is possible to suppress an illegal act such as taking away the main control device 201 together with the pedestal device 210.

  (H) In the slot machine of the above embodiment, a liquid crystal display device (15 inch or 17 wide inch liquid crystal device) having a relatively large screen is mounted as an auxiliary display portion, and an operation portion (table portion 40) is conventionally provided. Although it is provided at a height position below the machine, it may have a configuration in which a liquid crystal display device of a normal size is mounted and the operation unit is provided at the same height position as the conventional machine. Further, the auxiliary display device may have a configuration in which, for example, a dot matrix display other than the liquid crystal display device is mounted, or a configuration in which the auxiliary display unit is not mounted.

  (I) In the above embodiment, the three reels 471 to 473 constituting the reel unit 400 can be individually removed, but the three reels 471 to 473 may be integrated into a subassembly.

  (J) In the above embodiment, the front door 12 is constituted by the upper door 13 and the lower door 14, and the doors 13 and 14 are connected by the connecting plate 651. However, this connection may be eliminated. . That is, by eliminating the connection, the upper door 13 and the lower door 14 can be individually opened and closed.

(K) In the above embodiment, the upper door 13 is attached to the reel unit 400 so as to be openable and closable, and the lower door 14 is attached to the housing 11 so as to be openable and closable. For example, it is good also as a structure which attaches both the upper door 13 and the lower door 14 to the housing | casing 11 so that opening and closing is possible. Or it is good also as a structure which comprises the front door 12 without dividing | segmenting up and down, and attaches the front door 12 to the housing | casing 11 so that opening and closing is possible. However, the reel unit 400 is configured to mount the reel device 406 as described above. When the front door 12 is configured without being divided vertically, the reel unit 400 can be exchanged (replaced). The case and the door can be reused in the event of a unit failure.
It is possible to arrange them.

  (L) In the above embodiment, in the first sealing portion of the main board unit 200, the insertion-side coupling portions 291 are arranged in parallel with the front case body 271 in four lines, and the receiving-side coupling portions 251 are correspondingly arranged. The movable base plate 212 is arranged in parallel with four stations, 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, an appropriate sealing structure can be realized. Further, instead of the sealing performed by the front case body 271 and the movable base plate 212, the sealing performed by the back case body 272 and the movable base plate 212, or the sealing performed by the front and back case bodies 271 and 272, It is also possible to do.
