2. Description of the Related Art In recent years, in a control board storage box of a pachinko game machine of this type, a special symbol display device is driven by detecting a safe ball generated on a game board surface of the pachinko game machine to display a special symbol. And a main board for paying out a predetermined number of prize balls in accordance with the type of winning is attached to the mechanism plate. A cover member is attached to this main substrate, and unauthorized opening is prohibited by a seal. As this seal, a type in which a predetermined mark is formed by a laser marker is also known.

[0003] Alternatively, a type in which a reverse screw is used to fix a screw is also known. In this reverse screw type, when turning the reverse screw to open the cover member illegally, the tip of the reverse screw, that is, the part of the screw that is exposed to the outside, can be removed, and the cover member can be opened. Is not possible.

[0004]

However, in the case of such a conventional pachinko gaming machine as in a control board storage box in which prohibition of unauthorized opening by a seal is prohibited, the seal can be easily removed without leaving any trace. Therefore, by performing an artificial operation such as opening the control circuit board storage case and attaching a back ROM, a large amount of prize balls are paid out to the player, and conversely, the prize balls are not paid out to the player. In order to do so, it was actually possible to make the fever state hardly occur and to hurt the player.

[0005] Therefore, if a large amount of prize balls are paid out due to the misconduct of the player, the pachinko dealer will suffer great damage. On the other hand, if the prize balls are not paid out at all due to the misconduct of the pachinko dealer, the player will only waste his money and cannot win. For this reason, there is a tendency that the player does not enjoy the game for a long time or the frequency of going to the game hall decreases.

Further, a pachinko parlor breaks the seal so that a large amount of prize balls are paid out only to a specific stand, and operates the stand, and makes an insider disguise a customer as a player and play the game. , While encouraging the gambling of the general player, the hope is that if another player breaks the seal and opens the case so that almost no prize balls will be dispensed, the player will eventually be able to win. In practice, it is also possible, in practice, to force the player to frequently go to a platform where they have no chance of winning, causing a loss. Such illegal use would hinder sound economic activities of the gaming industry.

Further, according to the above-described screw for preventing reverse rotation, if a special tool is used, the screw can be turned without breaking the screw. Can be opened for unauthorized use.

The problem to be solved by the present invention is to prevent a control board storage box, in which a control board provided on the back of a pachinko gaming machine main body or the back of a game board is stored, from being left without leaving a trace, An object of the present invention is to provide a control board storage box in a pachinko gaming machine that prevents unauthorized use of a pachinko gaming machine.
