The credit display is subtracted every time the bet switch 23 is operated. Further, by operating the settlement switch 24, the credit display becomes “0” and the displayed number of game medals are paid out from the hopper to the medal tray 25.

(Medal insertion part 10)
Next, the medal insertion unit 10 will be described in detail.
As shown in FIGS. 1 and 2, the medal insertion portion 10 in the present embodiment is installed in a step portion 20B formed at the right end portion of the upper surface 20A of the operation portion 20. In addition, a fraud prevention device 14 is attached to the back surface of the insertion slot block 11 having the medal insertion slit 13 and the medal guiding recess 12 by welding or the like.
The medal guiding recess 12 is a recess having a substantially semicircular cross section provided from the front to the back of the insertion slot block 11, and its bottom 12a is formed to be slightly inclined upward from the front to the back. A plurality of game medals can be stacked in a standing state and placed in the recess. Further, as shown in FIGS. 1 and 3B, the left and right ridges of the medal guiding recess 12 are formed slightly lower in the front right ridge 11b than in the front left ridge 11a.

The medal insertion slit 13 is a horizontally long slit provided at the back end of the medal guiding recess 12 and is larger than the length of one game medal and the thickness of one game medal. The width is smaller than the thickness of the sheet. The medal insertion slit 13 communicates with a medal receiving port of a medal selector 40 provided below the medal insertion unit 10.
(Anti-fraud device 14)
As shown in FIGS. 1 and 3, the fraud preventing device 14 is a side inverted L-shaped angle member attached to the back surface of the insertion port block 11, and is a thin plate-like adhesive bonded to the back surface of the insertion port block 11. A standing piece 16 and a shielding plate 15 projecting horizontally from the upper end of the standing piece 16 to the near side are provided. The shielding plate 15 is for covering the medal insertion slit 13 from above, and the standing piece 16 is for fixing the shielding plate 15 at the position.

  Here, the shielding plate 15 has a lateral width W (see FIG. 3 (B)) that is substantially the same as the lateral width of the insertion port block 11, and a depth L (see FIG. 3 (C)) that is the same as that of the shielding plate 15 as viewed from above. The distance from the front end portion 15a to the medal insertion slit 13 is formed to have a length (see FIG. 3A) that is approximately the diameter of the game medal M. Further, from the lower surface of the shielding plate 15 to the center of the deepest part of the bottom 12a of the medal guiding recess 12, that is, the highest part of the bottom 12a and the lowest part of the concave medal insertion slit 13 having a substantially semicircular front sectional shape The height H (see FIG. 3B) is formed by adding a length that allows a human finger to enter the diameter of the game medal M. Specifically, when the diameter of the game medal is 24 mm, it is preferable that H is about 30 to 40 mm and L is about 20 to 30 mm.

In the example shown in the figure, the anti-fraud device 14 is attached to the back of the existing insertion slot block 11, so that a semicircular back plate 11c is formed on the back side of the medal insertion slit 13. When the mouth block 11 and the fraud prevention device 14 are integrally formed, the standing piece 16 may be used instead of the back plate. Although not particularly illustrated, if the corner portions of the shielding plate 15 are rounded, it is possible to prevent troubles such as hitting and damaging the hand when a medal is inserted.
When a game medal is inserted from the medal insertion part 10 formed in this way, if the game medal is appropriately placed in the medal guiding recess 12 and pressed in the back direction so as to sway the row of game medals, the tip The game medals are dropped one by one from the medal insertion slit 13 in order. At this time, the distance between the bottom 12a of the medal guiding recess 12 and the lower surface of the shielding plate 15 of the anti-fraud device 14 has a length that allows a finger to enter in addition to the diameter of the game medal. Sometimes the shielding plate 15 does not get in the way.

If two or three game medals are to be inserted, the game medals may be slid in from the right side of the medal insertion slit 13. At this time, since the right ridge 11b is formed low, it is easy to insert a medal from the side, and the shielding plate 15 and the standing piece 16 do not obstruct the insertion action.
On the other hand, in this medal insertion part 10, the shielding plate 15 of the anti-fraud device 14 covers the upper part of the medal insertion slit 13 completely, and the elevation of the step part 20B is on the left side of the front, as shown in FIG. Even if a curved goto tool 100 that matches the shape of the medal passage 40 of the medal selector 4 is inserted into the medal insertion slit 13, it cannot be easily inserted. Even if you can insert the goto tool 100 using a cell plate that is easy to bend, the shielding plate 15 is a hindrance to push until the light emitter 110 at the tip reaches the position of the medal sensor 41. is there. Therefore, it has the effect of preventing or suppressing malicious goto acts such as blinking the illuminant, pseudo-inserting a game medal, and adding the credit display to the maximum and pressing the settlement switch 24 to illegally pay out the game medal. I can expect.

As described above, according to the present embodiment, it is possible to provide the medal insertion unit 10 that does not interfere with the insertion of game medals and is unlikely to perform sexual acts using goto tools.

However, when the medal insertion section 10 is attached to the upper surface 20A of the operation section 20, FIG. As shown in FIG. 6, the insertion port block 11 and the fraud prevention device 14 can be separated and attached later.
That is, the fraud prevention device 14 shown in FIG. 4 (A) has the shielding plate 15 and the standing piece 16, and the installation plate 17 opposite to the shielding plate 15 is provided at the lower end of the standing piece 16. It is. The installation plate 17 is formed with an opening 18 having a width and depth larger than the width and depth of the existing inlet port block 11 ′. Then, if the installation plate 17 is placed so that the insertion slot block 11 ′ enters the opening 18, the shielding plate 15 is positioned above the medal insertion slit 13 ′ of the insertion slot block 11 ′. Is. The installation plate 17 may be formed of a thin metal plate or the like and fixed to the upper surface 20A of the operation unit 20 with an adhesive or the like.

Further, the fraud prevention device 14 shown in FIG. 4B is provided with a cap portion 19 that can be attached to the back plate 11c ′ of the insertion port block 11 ′ below the back side of the shielding plate 15. The cap portion 19 is a hollow thin tube having a lower opening, and can be fitted to the outside of the back plate 11c ′. When the cap portion 19 is attached to the back plate 11c ′, the shielding plate 15 is positioned above the medal insertion slit 13 ′ of the insertion port block 11 ′. The cap portion 19 may be fixed to the back plate 11c ′ with an adhesive, or may be fixed with a screw or the like.
By forming in this way, it is possible to quickly take measures against the goto without any modification to the current slot machine body.

  In addition to the above configuration, the retrofitting type anti-fraud device 14 is not particularly shown, but a hook-shaped shielding plate 15 protruding on the medal insertion slit 13 is attached to the front of the front door 2, A shielding plate 15 having legs may be attached to the upper surface 20A of the operation unit 20. In the latter case, the legs may be plate-shaped or columnar. The point is that the shielding plate 15 can be installed so as to cover the top of the medal insertion slit 13.
