DESCRIPTION OF THE PREFERRED EMBODIMENTS A pachinko machine will be described as an example of a gaming machine. The pachinko machine is advantageous to a player through a payout of a prize ball or a symbol display when a game ball wins in a specific place. Dispense a large amount of prize balls by generating a big jackpot. In order to control the game such as payout of a prize ball or a prize ball, a control element 3 such as a CPU with a built-in ROM or RAM,
A control board case 1 in which a control board 12 on which other components are mounted and fixed by screws or the like is mounted.

FIG. 1 is a rear view of a well-known pachinko machine. In the center of the rear surface, game balls that have won prizes in a prize port or the like provided on the front side of the game board are collected, and the prize ball processing device 62 collects them. A winning ball collecting gutter 61 to be separated for each ball is provided.
A control board case 1 for accommodating the control board 12 is attached to the lower left of the winning ball collecting gutter 61.

A storage tank 63 for storing game balls before discharge is provided at the upper part of the pachinko machine. From the storage tank 63, the game balls are arranged in two rows to reach a game ball discharge device 65. An alignment gutter 64 for guiding is provided. This alignment gutter 64 has a ball conditioner 6 for preventing game balls from overlapping.
6 is swingably provided vertically. The game ball discharging device 65
The game balls discharged from are discharged to the upper plate via the downflow gutter 67. A terminal board 69 is provided on the upper right side of the pachinko machine.
Is attached, and a game ball launching device 70 is provided at the lower left, so that each ball can be launched.

(First Embodiment) FIG. 2A is a perspective view of the control board case 1 with a partial cutout, FIG. 2B is a rear perspective view of the cover body 10, and FIG. FIG. 3B is a plan view of the substrate case 1, FIG. 3B is a cross-sectional view of A to A, and FIG.
It is sectional drawing.

The control board case 1 comprises a control board 12 on which the control element 3 and the like are mounted, a chassis 13 for fixing the control board 12 with screws 13a, and a box-shaped cover 10 covering the chassis 13. It is. Also, cover 1
Reference numeral 0 denotes a box formed of a transparent resin so that the inside can be seen, and a large number of air holes 11a are formed on the surface thereof for heat radiation, and screws are attached to the side of the chassis 13 by screws. A screw hole 11b for fixing is formed.

In addition, at a position corresponding to the control element (the element to be replaced and subjected to wrongdoing) 3 of the cover body 10,
The protruding body 18 is formed in a box shape having a bottom plate 18a of a length and a height which, when attached to the cover body 10, makes contact with the control element 3 or forms a slight gap. A cross-shaped reinforcing rib 20 joined to the side plate 18b is integrally formed on the bottom plate 18a (inside the protruding body 18).

Next, a description will be given of the prevention of unauthorized use of the control board case 1 having the above-mentioned structure.
3 and the chassis 13 is screwed with the cover body 10. Then, the cover body 10 cannot be opened unless the sealing paper 22 is adhered to the side surface between the cover body 10 and the chassis 13 and the sealing paper 22 is peeled off.

The control element 3 is in contact with the bottom plate 18a of the protrusion 18 formed integrally with the cover body 10 or with a slight gap. Inside the protrusion 18, the bottom plate 18a and the side plate are provided. Cross-shaped reinforcing rib 20 joined to 18b
Are integrally formed. For this reason, it is difficult to cut out the boundary (conventional outline B) of the bottom plate 18a of the protruding body 18 with a knife or the like, and when cut off, the trace remains, so that the control element 3 cannot be replaced. Fraud can be prevented.

(Second Embodiment) In this embodiment, a perspective view of a partially cut-out portion of a control board case 1 (FIG. 4A) and a rear perspective view of a cover body 10 (FIG. 4B) , A plan view of the control board case 1 (FIG. 5A), and a cross-sectional view of C to C (FIG. 5A).
(B)), as shown in the D-D cross-sectional view (FIG. 5 (C)),
The reinforcing rib 20 formed in the first embodiment is further provided with a reinforcing rib 20A having a different shape from the forming location.

The reinforcing ribs 20A extend outside the protruding body 18, ie, between the side plate 18b and the cover body 3.
Since the reinforcing ribs 20A are formed integrally in a square shape,
This can prevent the entire protruding body 18 (conventional contour line A) from being cut off. Also, protrusion 1
Since the side plate 18b of the control element 8 is extended so as to be in contact with the control board 12 or to have a slight gap, the control element 3
Is surrounded, making replacement from the side difficult.

Therefore, the bottom plate 18a is provided by the reinforcing ribs 20.
It is not easy to cut off the protruding body 18 with the reinforcing rib 20A from the boundary line (conventional contour B) of FIG.
Replacement becomes impossible and fraudulent acts can be prevented.
Needless to say, the shapes of the reinforcing ribs 20 and 20A are appropriately selected.

(Third Embodiment) This embodiment differs from the second embodiment in that a cross-shaped reinforcing rib 20B is formed integrally with the cover body 10, as shown in FIG. This is a shape in which the bottom plate 18a of the protrusion 18 is omitted. That is, the cover body 10 is formed integrally with the protruding body 18 via a side plate 18b that surrounds the control element 3 and substantially abuts the control board 12, and a cross-shaped reinforcing rib is provided on the back side of the canopy of the cover body 10. 20B are integrally formed, and similarly to the second embodiment, the reinforcing ribs 20A are formed integrally in a triangular shape outside the projecting body 18, that is, over the side plate 18b and the cover body 10. is there.

Therefore, these reinforcing ribs 20A, 20A
It is not easy to cut the protruding body 18 (conventional contours A and B) by B, and directly by the side plate 18b.
Since the control element 3 cannot be replaced by touching it, fraudulent acts can be prevented.

In forming the protrusion 18 for preventing fraud, the protrusion 18 is brought into contact with the control element 3 in consideration of the material (metal or synthetic resin) of the protrusion 18 as a measure against heat generation of the control element 3. It is desirable to form it with a gap or to consider the usefulness of forming the air hole.

For example, when the material of the protruding body 18 is a material having poor heat conductivity such as a synthetic resin, the bottom plate 18a is desirably formed so as to have a gap between the bottom plate 18a and the control element 3. Air holes are formed in 18a (and / or side plate 18b) to radiate heat. If the protruding body 18 is made of a metal material having good heat conductivity, it is preferable that the protruding body 18 is formed in contact with the base plate 18a, since it is preferable in terms of heat radiation that an air hole is not necessarily formed.

Although the control element 3 prevents the ROM from being pulled out, it goes without saying that the improper operation can be prevented by taking the same measures for the other control elements.

[0022]

According to the first aspect of the present invention, since the control board case is formed with a protrusion just above or surrounding the control element to be fraudulent, and a reinforcing rib is formed on the protrusion, the control board case is simple. Not only is it impossible to cut it off, but when it is cut off, its traces remain, so that cheating can be found.
