Abstract

PROBLEM TO BE SOLVED: To prevent a ROM from being pulled out by being caught by a projection part in trying to pull it out and prevent a dishonest act by forming the projecting part on a front cover body in a position matched with right above the ROM. SOLUTION: A figure A is an prospective view of a control box 1 having a partial cutaway view and a projection part 100 is formed on a front cover body 10 in a position matched with right above a ROM 101 installed on a control substrate 12. When the control box 1 is assembled, (cf. figure B) the projection part 100 may be in contact with the ROM 101, however, it is preferable to form a clearance impossible of pulling out the ROM 101 by taking account of the heat radiation. When the projection part 100 is formed in this way, the ROM 101 is prevented from being pulled out by drawing out a pin from a socket in a state of having no clearance right above. This constitution eliminates any possibility of exchanging the ROM with a false one. The formation of such a projection part 100 allows an air hole 102 to be formed right above the ROM so as to radiate the heat.

Is mounted, and a game ball launching device 91 is provided at the lower left, so that each ball can be launched.

FIG. 2 is an exploded view of parts of the control box 1. The control box 1 has a box-shaped front cover body 10 and a back cover body 11,
It comprises a control board 12 to which a control element (not shown) is attached and a chassis 13 to which the control board is fixed. The rear cover 11 has a protruding plate 105a erected, while the chassis 13 has an insertion hole 1 at a position corresponding to the protruding plate 105a.
05b is open. Then, when the control box 1 is assembled, as shown in FIG.
a is substantially inserted into the control board 12 through the insertion hole 105b, and the gap 58b formed in the related art is eliminated.
The front cover body 10 is also formed longer than in the past, and the gap 58a formed in the past between the front cover body 10 and the control board 12 is eliminated. By forming the control box 1 in this way,
Even if the front cover 10 made of synthetic resin is deformed,
Because it is not possible to form a gap for discharging
Even if the ROM 101 is removed, it cannot be ejected, making it impossible to exchange the ROM with an unauthorized ROM, thereby preventing an illegal act.

FIG. 3A is a perspective view in which a part of the control box 1 is cut away. The front cover body 10 has a position corresponding to the upper surface of the “ROM 101” installed on the control board 12. A protruding portion 100 is formed at the bottom. The protrusion 100
When the control box 1 is assembled (see the cross-sectional view of FIG. 3B), it may be in a state of contacting the “ROM 101”, but it is impossible to remove the ROM 101 in consideration of heat radiation. It is desirable to make a gap. Thus, the ROM 10
When the protrusion 100 is formed on the upper surface of the ROM 1, the pin is removed from the socket and the ROM 1
01 cannot be removed.

As described above, the protruding portion 1 is attached to the front cover body 10.
When 00 is formed, the ROM 101 cannot be pulled out,
Exchange with an unauthorized ROM becomes impossible. When the protrusion 100 is formed in this manner, the air hole 102a is
It can also be formed directly above 1 to dissipate heat and cannot be pulled out from the air hole 102a via a wire or the like. Also, as shown in FIG.
By providing the skirt portion 100a with the “0” further extended around the ROM 101, it is further difficult to remove the ROM 101. In this case, the air holes 10 for heat radiation are used.
Even if the protrusions 2a and 102b are provided on the protruding portion 100 and the skirt portion 100a, the ROM 101 cannot be removed, and the heat radiation function can be performed together.

In the control box 1 of the present embodiment, the front cover body 10 and the back cover body 11 are prevented from tampering through fastening members A and B instead of sticking a sealing paper. I have. That is,
When the fastening members A and B are mounted, they are fixed via locking claws (not shown), and the front cover body 10 and the back cover body 11 cannot be opened unless the fastening members A and B are cut. Therefore, the control box 1 cannot be opened by the fastening members A and B, and the "ROM 101" cannot be pulled out by the protruding portion 100 formed on the front cover body 10, so that illegal acts can be prevented.

(Second Embodiment) Next, another measure for preventing fraud will be described with reference to FIG. 4A is a plan view of the front cover body 10, FIG. 4B is an enlarged view of a cutaway section of the recess 110, and FIG. 4C is an overall perspective view of the control box. A plurality of rectangular recesses 110 are formed in the front cover body 10 at appropriate positions for heat dissipation, and air holes 111 for heat dissipation are formed on the side surfaces of the recesses 110 other than the bottom 110a (FIG. 4 (B)). Therefore, when a wire is inserted into the air hole 111, the wire cannot be inserted in the vertical direction as in the related art,
Since the wire is inserted in the horizontal direction, it becomes difficult to pull out the ROM 101.

After assembling the front cover body 10 with the back cover body 11 and assembling the chassis 13 and the like and then assembling a seal paper 56 over the front cover body 10 and the back cover body 11, the seal paper 56 Unless it is broken, the front cover 10 cannot be opened, and it becomes difficult to insert the wire vertically, and it is difficult to pull out the ROM 101. still,
When the air holes 111 are formed in this manner, the air holes 111 can be formed directly above the “ROM 101” as in the conventional case, and a heat radiation effect can be achieved.

(Third Embodiment) This embodiment is similar to FIG.
5A is a component diagram, FIG. 5B is a plan view of a control box, and FIG. 5C is a cross-sectional view of the control box. The control box according to the present embodiment includes a plurality of (two) front cover bodies 10a,
b, and the heat-dissipating air holes 120a drilled in the front cover body 10a are formed at positions where they do not communicate with the heat-dissipating air holes 120b drilled in the front cover body 10b. I have. When the control box is formed with the chassis 13 by superimposing the plurality of front cover bodies 10a and 10b, a space 122 is formed between the front cover bodies 10a and 10b to radiate heat as shown in FIG. In addition to the function, even if a wire is inserted through the air hole for heat radiation 120a, the wire is not communicated with the air hole for heat radiation 120b, so that the ROM 101 cannot be removed properly. As described above, the control box is formed by the plurality of front cover bodies 10a and 10b, and by forming the control box in a position where the formed air holes 120a and 120b do not communicate with each other, fraudulent acts can be prevented. By forming the air holes 120a and 120b in the above, the positions of the air holes 120a and 120b may be directly above the ROM 101, and can be arbitrarily formed.

(Fourth Embodiment) This embodiment can be easily constructed, and the front cover 10 is provided with a ROM.
An air hole is not formed immediately above the position 101, and is different from the position directly above the ROM 101, that is, a position where the ROM 101 cannot be pulled out easily with an inclined wire inserted from the air hole (not shown). Forming an air hole at such a position is simple and effective means against fraud.

Although the above-described arrangement is intended to prevent the ROM 101 from being pulled out, it is possible to prevent improper operation by taking the same measures for other control elements.

[0017]

According to the present invention, a protrusion is formed on the front cover body, an air hole is formed on a side surface other than the bottom of the concave portion, or air is pierced through a plurality of front cover bodies. By providing a hole at a position where it does not communicate or forming an air hole at a position other than the portion corresponding to the upper surface of the ROM, it becomes difficult to pull out the ROM or the like, thereby preventing fraud.
