It becomes difficult to enter the inside, and illegal acts on the main power supply device 340 can be prevented.

  On the other hand, the opening for releasing the heat to the outside is formed on the bottom surface and the back surface of the cover main body 360. That is, the bottom surface opening 367a of the bottom surface of the cover body 360 extends downward from the bottom of the cover body 360 and is formed in a louver shape with the opening directed rearward, so that heat generated in the cover body 360 is generated. Heat is dissipated to the outside. As a result, the bottom opening 367a is directed to the bottom of the housing 2, and the opening is open toward the rear of the slot machine 1, that is, the opposite side to the player side (front side). It becomes difficult for a tool such as a wire or a wire to enter the inside of the cover main body 360 from the bottom surface opening 367a, and illegal acts on the main power supply device 340 can be prevented.

  Further, the back opening 367b on the back surface of the cover main body 360 is located on the farthest side from the player side (front side), which is the back of the slot machine 1, so that tools such as cells and wires can be attached to the cover main body 360. It becomes difficult to penetrate inside. Therefore, the back opening 367b can be formed, for example, in a circular shape in order to enhance the heat dissipation effect, weight reduction, and the like. Note that the back surface opening 367b is not limited to a circle, and may have another shape such as a triangle or a square, and may have a louver shape similar to that of the bottom surface opening 367a.

  The operation plate 370 has a plate-like form, and 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, or ABS resin. As a result, hall staff or the like can confirm the appearance of various components and circuits of the power board unit 350 in the cover main body 360 through the operation plate 370. Further, as shown in FIGS. 6 and 7, the operation plate 370 has an attachment hole 371 a for attaching a power switch 371 for operating the slot machine 1 and a setting switch 372 for setting a payout rate of the slot machine 1.

  Further, the operation plate 370 has an operation hole 374a for operating the stop switch 356 for setting the presence / absence of the above-described stop processing, and an automatic settlement switch 357 for setting the presence / absence of the above-mentioned automatic settlement processing. A fitting recess 375 is formed to fit the operation hole 374 b and a convex back surface portion 385 d of a lock piece operation portion 385 described later of the cover panel 380. Here, the stop switch 356 and the automatic settlement switch 357 are arranged so as to move up and down inside the operation holes 374a and 374b, and are configured not to protrude from these operation holes 374a and 374b. In addition, fraudulent acts on the stop switch 356 and the automatic checkout switch 357 with tools such as cells and wires can be prevented.

  Further, as shown in FIG. 11, a power cable 359 having a connection connector 359a is connected to the power switch 371 through a connector 371b. Note that an intermediate portion of the power cable 359 is fixed to the substrate 351 side by a holder 371c. The power switch 371 is connected to the stop switch 356 side via a connector 371d and a cable 371e.

Further, as shown in FIG. 10, a lock piece 376 having a tapered portion 376a and a locking step portion 376b at the tip is provided in a horizontal direction at a position close to the edge side of the operation plate 370 of the fitting recess 375 of the operation plate 370. A loose fitting hole 376c that can be slightly tilted is formed, and the tip of the lock piece 376 projects outside from the loose fitting hole 376c.

  In addition, mounting fixing portions 376d for attaching the operation plate 370 to the front surface side of the cover main body 360 are formed at the four peripheral portions of the operation plate 370 with fixing holes 376e, and the positions of the fixing holes 376e are defined. The operation plate 370 is fixed to the screw hole 362a by passing an operation plate attachment screw (not shown) through the fixing hole 376e in accordance with the screw hole 362a of the operation plate attachment portion 362 formed on the front surface side of the cover body 360. The cover body 360 is attached to the front side. Further, a stepped portion 377a is formed so as to be connected to the periphery of the operation plate 370, and the surface center side of the operation plate 370 is configured to protrude. 7 and 10 is a rib formed on the same line as the stepped portion 377a when the fitting recess 375 is formed.

  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.

  As described above, in this embodiment, the board 351 of the power board unit 350 on which components for generating power necessary for the operation of the slot machine 1 are mounted is used as the cover body 360 having the cover side plate 361 as a box body. An operation plate 370 having operation switches such as a power switch 371, a setting switch 372, a reset button 373 and the like is provided on the front side of the box body to allow the slot machine 1 to perform a predetermined operation. An outer rib 377b as a first rib band protruding toward the cover panel 380 is provided around the surface of the operation plate 370, and the surface of the operation panel 370 is provided around the cover panel 380. Is protruded toward the surface of the operation plate 370 and the inner side of the outer rib 377b at the closed position of the cover panel 380. It was provided around the rib 381 of the second rib zone abutting.

  Accordingly, since the periphery of the cover panel 380 is covered with the outer rib 377b at the closed position of the cover panel 380, the periphery of the cover panel 380 is isolated from the outside, and accordingly, cells and wires are surrounded around the cover panel 380. And the like, and the insertion of tools such as cells and wires into the surface of the operation plate 370 from the gap around the cover panel 380 is prevented. Cheating can be prevented more reliably.

  Further, in the present embodiment, a stepped portion 377a is formed on the inner side of the outer rib 377b of the operation plate 370 so that the center side of the surface of the operation plate 370 protrudes along the outer rib 377b. Since the peripheral rib 381 of the cover panel 380 is accommodated between the rib 377b, for example, a part of the outer rib 377b of the operation plate 370 may be broken by a tool such as a cell or a wire. However, the stepped portion 377a can prevent the insertion of a tool such as a cell or wire into the surface of the operation plate 370.

  Further, in this embodiment, a coil that attaches a cover opening / closing support portion 378a that supports the cover panel 380 so as to be freely opened on one side and a torsion coil spring that urges the cover panel 380 to the closed position is provided on one end of the operation plate 370. A spring mounting portion 378b is provided, and a lock piece 376 for locking the opening of the cover panel 380 is disposed at the other end of the operation plate 370 so as to be tiltable in a direction orthogonal to the opening / closing direction of the cover panel 380. The lock can now be released by tilting.

  Thereby, in order to open the cover panel 380, the tip of the lock piece 376 is moved in the horizontal direction on the finger engagement piece 386 side to release the lock, and the cover panel 380 is moved up and down on the left end portion of the cover panel 380. An operation of rotating the cover panel 380 in the direction orthogonal to the unlocking direction by the lock piece 376 on the front side with the provided cover attaching portion 383a as a fulcrum is required.

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

  In the present embodiment, the operation panel 370 and the cover panel 380 are formed by a molding means such as injection molding using a transparent resin material such as polycarbonate, methacrylic resin, and ABS resin. The state of each operation switch and the like disposed on the operation plate 370 can be confirmed through the surface portion 382 in a state where the surface of the cover body 360 is covered, and the power supply in the cover main body 360 can be confirmed through the surface portion 382 of the cover panel 380 and the operation plate 370 The appearance of various components and circuits of the board unit 350 can be confirmed.

  In the present embodiment, in order to release heat generated inside the cover main body 360 to the outside, a bottom opening 367a is provided on the bottom surface of the cover main body 360, and a back opening 367b is provided on the back surface of the cover main body 360. did. Thereby, even if the upper surface and the side surface of the cover main body 360 and the cover side plate 361 are not formed with openings for releasing the heat generated inside the cover main body 360 to the outside, the bottom opening 367a and the rear opening 367b Heat can be released to the outside.

  Further, the upper surface and the side surface of the cover main body 360 and the cover side plate 361 are not formed with an opening for releasing heat generated inside the cover main body 360 to the outside, and the back opening 367b on the back surface of the cover main body 360 is Since it is located farthest from the player side (front side), which is behind the slot machine 1, it is possible to make it difficult for tools such as cells and wires to enter the inside of the cover main body 360.

  In this embodiment, for example, as shown in FIG. 10, the locking step portion is formed by the lock piece 376 on the operation plate 370 side inserted from the lock piece insertion hole 385 a of the lock piece operation portion 385 of the cover panel 380. Although the case where the opening of the cover panel 380 is locked by the 376b being engaged with the opening edge portion 385c on the surface side of the lock piece insertion hole 385a has been described, the present invention is not limited to this example, and is shown in FIGS. By using such a cover member 390, it is possible to more firmly prevent an illegal act with respect to each operation switch disposed on the operation plate 370.

  That is, the cover member 390 has substantially the same thickness as the gap of the lock piece insertion hole 385a formed when the lock piece 376 is inserted into the lock piece insertion hole 385a and the opening of the cover panel 380 is locked. The leg portion 391, the crown portion 392 to be crowned on the finger engagement piece 386, the engagement protrusion 393 with which the finger or the like is engaged when removing the cover member 390, and the displacement of the cover member 390 are prevented. It has the latching protrusion 394, and these are formed integrally. In addition, a locking hole 386 a is formed in the finger engaging piece 386 in accordance with the locking protrusion 394 provided on the cover member 390.

  Further, like the operation plate 370 and the cover panel 380, such a cover member 390 is integrally formed into a shape shown in the figure by a molding means such as injection molding using a transparent resin material such as polycarbonate, methacrylic resin, or ABS resin. Formed.

  Then, after the cover panel 380 is locked by the lock piece 376 and positioned at the closed position, as shown in FIG. 12, the leg portion 391 of the cover member 390 is inserted into the lock piece insertion hole 385a, and further on the operation plate 370 side. When pushed toward the loose fitting hole 376c, as shown in FIG. 13, the crowned portion 392 is crowned on the finger engaging piece 386, and the locking projection 394 is locked in the locking hole 386a of the finger engaging piece 386. Is done. On the other hand, when removing the cover member 390, if the finger or the like is engaged with the engaging portion 393 and pulled, the locking protrusion 394 is detached from the locking hole 386a of the finger engaging piece 386, and the cover member 390 can be pulled out. it can.

  By doing so, the gap of the lock piece insertion hole 385a formed when the lock piece 376 is inserted into the lock piece insertion hole 385a and the opening of the cover panel 380 is locked is formed by the leg portion 391 of the cover member 390. Since it is buried, tilting of the lock piece 376 necessary for unlocking by the lock piece 376 is prevented, and an unauthorized act of opening the cover panel 380 using a tool such as a wire can be further prevented.

  The cover panel 380 can be 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 by moving the cover panel 380 up and down the left end of the cover panel 380. In addition to the operation of rotating the cover panel 380 in the direction orthogonal to the unlocking direction by the lock piece 376 on the front side with the cover mounting portion 383a provided on the fulcrum as a fulcrum, the operation of removing the cover member 390 Is required. For this reason, it is extremely difficult to open the cover panel 380 by performing these three operations using a tool such as a wire. Therefore, tools such as a cell and a wire enter the front side of the setting switch 372 and the reset button 373. It becomes difficult, and the illegal act with respect to the setting switch 372, the reset button 373, etc. can be prevented more firmly.
