  One type of gaming machine is a spinning machine, for example, a slot machine. The slot machine includes a plurality of reels as rotating bodies with a plurality of symbols attached thereto, and each reel starts rotating when a player inserts a medal and operates a start lever. After each reel starts rotating, each reel is sequentially stopped by operating a stop button or elapse of a predetermined time.

  Also, in the slot machine, a lottery is performed on condition that the medal is inserted and the start lever is operated, and the lottery result is a win, and the player has to stop the winning symbol on the preset active line. As a result, a predetermined number of medals are paid out, or a special gaming state (bonus game or the like) advantageous to the player occurs.

  In addition, such a slot machine includes a box-shaped housing having an opening on the front surface side, and a front door attached to the front surface side of the housing so as to be openable and closable. It is arranged and used for games with the front door covering the opening. In addition, a power supply device for supplying power to each part of the slot machine is provided inside the casing, and the slot machine is operated by the power supplied from the power supply device.

  By the way, on the front side of the power supply unit, there are a power switch for operating the slot machine, a medal collection switch for collecting game medals, and a setting switch for setting the payout rate of the slot machine, etc. An operation plate having operation switches is provided, and each operation switch can be operated in a state where the front door is opened, so that maintenance work of the slot machine, work-out management work, and the like can be performed.

  In other words, by operating the medal recovery switch with the front door open, the game medals are collected by forcibly paying out the game medals from the medal payout device. Similarly, the setting is made with the front door open. By controlling the switch and setting the output rate of the slot machine, the output of the slot machine is managed.

  Such a power supply device can be isolated from the outside by covering the opening of the housing with the front door, and each operation switch on the operation plate of the power supply device will not be illegally operated unless the front door is opened. ing.

  Further, an outer rib 377b as a first rib band is formed around the step portion 377a so as to follow the step portion 377a. A peripheral rib 381 as a second rib band of the cover panel 380 is accommodated in a gap between the stepped portion 377a and the outer rib 377b. Thus, the peripheral rib 381 of the cover panel 380 is guarded by the outer rib 377b of the operation plate 370, so that the cover panel 380 is not opened by a tool such as a wire and the cover panel 380 is not opened. Unauthorized acts on the device 340 can be prevented.

  In addition, a cover opening / closing support portion 378a as an opening / closing support portion for attaching the cover panel 380 to the operation plate 370 so that the cover panel 380 can be opened and closed horizontally is formed in a bar shape above and below the left end portion of the operation plate 370. A rod-like coil spring mounting portion 378b as a biasing member mounting portion is formed at the lower left end portion of the operation plate 370, and a biasing member (not shown) that biases the cover panel 380 to a closed position that covers the surface of the operation plate 370. A torsion coil spring or the like as a biasing member is attached. Further, a groove-shaped first torsion coil spring receiving portion 378c is formed on the rear surface side of the left lower end portion of the operation plate 370, and is configured to receive one end side of a torsion coil spring (not shown).

  Here, for the convenience of processing by injection molding of the operation plate 370, the upper and lower opening / closing support portions are provided at the positions where the cover opening / closing support portion 378a and the coil spring mounting portion 378b are formed on the operation plate 370, as shown in FIGS. A part opening 378d and a spring attachment part opening 378e are formed. However, the opening / closing support portion opening 378d and the spring attachment portion opening 378e are blocked by the operation plate attachment portion 362 having the screw hole 362a for attaching the operation plate 370 to the cover main body 360 described above. Since the tools such as the cell and the wire are prevented from entering the inside of the cover main body 360, illegal acts on the main power supply device 340 can be prevented.

  Similar to the operation plate 370, the cover panel 380 is integrally formed in a shape shown in the figure by a molding means such as injection molding using a transparent resin material such as polycarbonate, methacrylic resin, ABS resin or the like. As shown in FIGS. 5 and 6, a surface portion 382 is formed in the center portion of the cover panel 160 so as to be aligned with the surface center side of the operation plate 370, and the cover panel 380 covers the surface of the operation plate 370. Hall staffs can confirm the appearance of the operation switches and the like disposed on the operation plate 370 through the surface 382. Further, the hall staff and the like can confirm the appearance of various components and circuits of the power supply board unit 350 in the cover main body 360 through the surface portion 382 of the cover panel 380 and the operation plate 370.

  A cover mounting portion 383a and a stopper 383b that are respectively engaged with the upper and lower cover opening / closing support portions 378a of the operation plate 370 are formed above and below the left end portion of the cover panel 380. Then, as shown in FIG. 6, the cover mounting portion 383 a engages with the cover opening / closing support portion 378 a so that the cover panel 380 covers the operation plate 370 from the closed position where the surface of the operation plate 370 is covered, as shown in FIG. 7. Thus, it can be freely opened and closed to the side opening opening position. At this time, the stopper 383b of the cover panel 380 shown in FIG. 8 is brought into contact with the surface of the operation plate 370, and the opening position of the cover panel 380 is restricted.

  As shown in FIGS. 6 and 8, a groove-like second torsion coil spring receiving portion 383c is formed at the lower left end portion of the cover panel 380, and receives the other end side of the torsion coil spring or the like (not shown). It is configured as follows. Then, a torsion coil spring or the like (not shown) is attached to the coil spring mounting portion 378b of the operation plate 370, and one end side of the torsion coil spring or the like is received by the first torsion coil spring receiving portion 378c of the operation plate 370. The other end side of the spring or the like is received by the second torsion coil spring receiving portion 383c, so that the cover panel 380 covers the surface of the operation plate 370 by a torsion coil spring or the like provided across the operation plate 370 and the cover panel 380. It is biased to the closed position to cover. As a result, even if a hole staff or the like forgets to place the cover panel 380 in the closed position, the cover panel 380 is located in the closed position due to the biasing force of a torsion coil spring (not shown), so that it is disposed on the operation plate 370. Unauthorized acts on each operation switch can be prevented.

  As shown in FIGS. 7, 8, and 11, the cover panel 380 is in contact with the stepped portion 377 a of the operation plate 370, and is fitted in a gap between the stepped portion 377 a and the outer rib 377 b. A peripheral rib 381 is formed. The peripheral rib 381 is formed so as to align with the gap between the stepped portion 377a and the stepped portion 377a and the outer rib 377b so as to be connected to the periphery of the cover panel 380 and project rearward of the slot machine 1. When 380 is positioned at the closed position, the cover panel 380 comes into contact with the stepped portion 154 and the outer rib 377b, and further covers the surface of the operation plate 370 while being accommodated in the gap between the stepped portion 377a and the outer rib 377b. Configured.

  Therefore, the stepped portion 377a makes it difficult for tools such as cells and wires to enter the surface of the operation plate 370 covered by the cover panel 380, and the outer ribs 377b guard the peripheral ribs 381 of the cover panel 380. The cover panel 380 is not hooked by the tool of this time and the cover panel 380 is not opened to some extent, and it becomes difficult for tools such as cells and wires to enter the surface of the operation plate 370 and disposed on the operation plate 370. It is possible to prevent an illegal act with respect to each of the operated switches.

  As shown in FIG. 8, a switch surrounding rib 384 a that contacts the peripheral portion of the setting switch 372 and a switch peripheral rib 384 b that contacts the peripheral portion of the reset button 373 are formed inside the cover panel 380. As shown in FIG. 11, these switch peripheral ribs 384a and 384b are formed so as to be aligned with the peripheral portions of the setting switch 372 and the reset button 373 so as to protrude to the rear of the slot machine 1, and the cover panel 380 When it is positioned at the closed position, it contacts the peripheral portions of the setting switch 372 and the reset button 373, and in this state, the surface side of the setting switch 372 and the reset button 373 is configured to be surrounded by the switch surrounding ribs 384a and 384b. For this reason, these switch peripheral ribs 384a and 384b make it difficult for tools such as cells and wires to enter the front side of the setting switch 372 and the reset button 373, so that it is possible to prevent an illegal act on the setting switch 372 and the reset button 373. .

  In addition, a lock piece operation portion 385 formed so as to be recessed toward the back side of the cover panel 380 is provided at the center of the right end of the cover panel 380. A lock piece insertion hole 385a into which the tip of the lock piece 376 of the operation plate 370 described above is inserted is formed at the right end of the lock piece operation portion 385. The lock piece insertion hole 385a is slightly tilted when the lock piece 376 is locked and unlocked, that is, the locking step 376b of the lock piece 376 is locked to the opening edge 385c on the surface side of the lock piece insertion hole 385a. Or a width that allows tilting associated with the release of the locking by the locking step 376b. In addition, a finger engagement piece 386 that protrudes toward the surface side of the cover panel 380 is formed at a position near the lock piece operation part 385 on the outer peripheral edge of the cover panel 380.

  Here, when the cover panel 380 is positioned at the closed position, when the right side of the cover panel 380 is pushed into the operation plate 370 side with the cover mounting portions 383a provided at the top and bottom of the left end of the cover panel 380 as fulcrums, The opening edge 385b on the back side of the lock piece insertion hole 385a of the lock piece operation portion 385 shown in FIG. 10 contacts the tapered portion 376a at the tip of the lock piece 376 of the operation plate 370. When the right side of the cover panel 380 is further pushed into the operation plate 370 in this state, the tip of the lock piece 376 slightly tilts to the right against its own elastic force, and when the cover panel 380 reaches the closed position, The distal end of the lock piece 376 is restored to its original position by the elastic force, and the locking step 376 b of the lock piece 376 is locked to the opening edge 385 c on the surface side of the lock piece insertion hole 385 a of the lock piece operating portion 385.

  At this time, the convex back surface portion 385d of the lock piece operating portion 385 is fitted into the fitting concave portion 375 of the operation plate 370 described above, and the cover panel 380 is locked in the closed position by the lock piece 376. In addition, the code | symbol 385e shown in FIG. 10 is an operation part rib provided when the lock piece insertion hole 385a was formed in the lock piece operation part 385, and the same line as the level | step-difference part 377a by the side of the operation plate 370 mentioned above. It fits inside the rib 377c formed.

  On the other hand, when releasing the lock by the lock piece 376, the thumb is engaged with the tip of the lock piece 376 engaged with the opening edge portion 385c on the surface side of the lock piece insertion hole 385a of the lock piece operation portion 385, and When the index finger is engaged with the finger engaging piece 386 and the tip of the lock piece 376 is pushed into the finger engaging piece 386 side with the thumb, the locking step portion 376b of the lock piece 376 is inserted into the lock piece operating portion 385. It is removed from the opening edge 385c on the surface side of the hole 385a. In this state, when the finger engaging piece 386 is pulled to the near side by the index finger, the cover panel 380 is rotated to the near side with the cover attaching portion 383a provided on the upper and lower left ends of the cover panel 380 as a fulcrum. 380 is opened.

  As described above, the cover panel 380 is opened by moving the tip of the lock piece 376 in the horizontal direction on the finger engagement piece 386 side to release the lock, and moving the cover panel 380 up and down the left end of the cover panel 380. An operation of rotating the cover panel 380 in the direction perpendicular to the direction of releasing the lock by the lock piece 376 on the front side is required with the cover mounting portion 383a provided on the fulcrum as a fulcrum.

  As a result, it is difficult to perform these two operations using a tool such as a cell or wire and open the cover panel 380. Therefore, the tool such as a cell or wire is used as the surface of the setting switch 372 and the reset button 373. It is difficult to enter the side, and illegal actions on the setting switch 372 and the reset button 373 can be prevented.

  The lock piece operation unit 385 is provided at the center of the right end of the cover panel 380, but is not limited thereto, and may be provided at the lower right end of the cover panel 380. In this case, the attachment position of the finger engagement piece 386 and the lock piece 376 on the operation plate 370 side may be changed according to the position of the lock piece operation portion 385. Further, the number of lock piece operation units 385 is not limited to one, and may be two or more. In this case, two or more lock pieces 376 on the operation plate 370 side may be provided.

  In this way, the cover panel 380 is locked and held in the closed position by the plurality of lock pieces 376, so that the cover panel 380 is prevented from being lifted, and an operation in which a tool such as a cell or wire is covered with the cover panel 380 is performed. Since it becomes more difficult to enter the surface of the plate 370, an illegal act with respect to each operation switch disposed on the operation plate 370 can be prevented.

  12-16 is a figure for demonstrating the detail of the structure in connection with attachment and removal of the operation board 370 mentioned above. Here, FIG. 12 is a perspective view showing the main power supply device 340 of FIG. 5, FIG. 13 is a perspective view for explaining details of the configuration relating to the attachment and detachment of the cover side plate 361 of the main power supply device 340 of FIG.
