[0002]

2. Description of the Related Art For example, in ball-and-ball game machines such as pachinko machines,
On the game board, game parts such as starting means, winning means, variable symbol display means, big winning means are arranged, while electronic parts including CPU, ROM, RAM and the like are mounted on the main control board in the board case, An electronic control system is used in which a game operation by each game component is controlled by an electronic component such as a ROM on the main control board.

In this type of ball-and-ball game machine, electronic parts such as a ROM mounted on a main control board are prevented from being tampered with, and at the time of inspection by a regulatory agency, the main control board is easily removed from the board case. Must be removable.

Therefore, conventionally, the entire board case is made of a transparent synthetic resin material through which the inside main control board can be seen, and a sealing means that leaves a trace of unsealing when opened is provided on the board case. We take various measures to prevent wrongdoing.

[0005]

In the conventional countermeasures against wrongdoing, the sealing means is released and the board case is opened so that no trace of opening is left. In the case of improper operation such as mounting a so-called back ROM that has been tampered with, the improper discovery of the improper operation can be made even if the electronic means on the main control board side in the board case is viewed from the outside. Have difficulty.

In particular, when the back ROM is mounted on the back side of the electronic component, since the electronic component is mounted on the main control board via the socket, the main control board is in the way and the back side of the electronic component is confirmed. There is a drawback that it is not possible and its discovery is very difficult.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a gaming machine control device capable of easily detecting an illegal operation when an illegal operation is performed on the back side of an electronic component.

That is, the main control board 22 is provided with the perforated portion 60, and the perforated portion 60 is provided with the lens portion 63 for enlargement. The lens unit 63 is configured by a convex lens or the like so that the focal point is on the back surface side of the integrated circuit device 51.
When the integrated circuit device 51 is long, the lens unit 63 may be formed along the longitudinal direction of the integrated circuit device 51.
Further, the lens unit 63 may be provided with a Fresnel lens instead of the convex lens. Other configurations are the same as those of the first embodiment.

By providing the lens portion 63 in the perforated portion 60 of the main control board 22 in this way, even if the integrated circuit device 51 is small, the back side of the integrated circuit device 51 can be seen through in an enlarged state,
The back side of the integrated circuit device 51 can be easily confirmed through the small perforated portion 60 of the main control board 22, and even a small illegal operation can be easily found. Further, the perforated portion 60 can be closed by the lens portion 63.

FIG. 9 illustrates a third embodiment of the present invention,
In the board case 8, the perforated part 60 (the see-through part 59) of the main control board 22 is provided.
In response to this, a lens unit 63 for enlargement is provided as an integral or separate structure. That is, the case body 15 of the substrate case 8 is provided with a lens portion 63 such as a convex lens so that the focal point is on the back side of the integrated circuit device 51. Also in this case, if the integrated circuit device 51 is long, the lens unit 63 may be formed along the longitudinal direction of the integrated circuit device 51. Also lens section
The 63 may be provided with a Fresnel lens instead of the convex lens. Other configurations are the same as those of the first embodiment.

As described above, the main control board 22 is mounted on the board case 8.

The back side of the integrated circuit device 51 can be easily confirmed via the small perforated portion 60 of 22 and even a small unauthorized manipulation can be easily found. The lens unit 63 may be provided in both the perforated portion 60 on the main control board 22 side and the board case 8 by using the second embodiment and the third embodiment together.

FIG. 10 exemplifies a fourth embodiment of the present invention, in which the socket 54 is formed in a frame shape so that substantially the whole of the integrated circuit device 51 including the central portion on the back side can be seen through from the back side.
The inside of the socket 54 is made into one perspective window 55, and the main control board
The twenty-four see-through portions 59 are constituted by one perforated portion 60 having a size corresponding to the see-through portion 55. In this case, substantially the entirety including the central portion of the integrated circuit device 51 can be seen through from the back side from the see-through portion 55 side.

FIG. 11 illustrates a fifth embodiment of the present invention, in which an electronic component 64 and a main control board, which are liable to be tampered with.
The electronic component 64 is mounted on the main control board 22 via a lead terminal 53 or the like at a predetermined distance from the main control board 22, and a hole is formed in the main control board 22 so that the back side of the electronic component 64 can be seen through. 60
Is formed. The perforated portion 60 is provided at a position outside a range facing the back surface of the electronic component 64 and at a position where the back side of the electronic component 64 can be seen through.

In this case, when viewed obliquely (in the direction indicated by the arrow) through the perforated portion 60, the back side of the electronic component 64 can be seen through. As described above, the perforated portion 60 can be provided at a position outside the range facing the back surface of the electronic component 64 as long as the position can be seen through the back side of the electronic component 64. Therefore, the interval between the lead terminals 53 of the electronic component 64 is small,
If the perforated portion 60 cannot be perforated in a range facing the back surface of the 64, the perforated portion 60 can be provided outside the range.

In this case, a lens unit 63 may be provided on the main control board 22 and / or the board case 8 as in the second and third embodiments.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments.
