2. Description of the Related Art In recent years, in a control board storage box in a pachinko gaming machine of this type, a safe symbol generated on the game board surface of the pachinko gaming machine is detected to drive and control a special symbol display device to display a special symbol. A main board or the like is mounted on the mechanism board for controlling the setting switching of the game and paying out a predetermined number of prize balls according to the type of winning. A cover member is attached to the main substrate, and unsealing is prohibited by a seal certificate. As this seal, a type in which a predetermined mark is formed by a laser marker is also known.

Alternatively, a type in which a reverse screw is used for screwing is also known. With this reverse screw type, if you turn the reverse screw to open the cover member illegally, you can remove the tip of the reverse screw, that is, the part of the screw that is exposed to the outside, and open the cover member. You can't.

However, in the case of prohibiting the unauthorized opening by the seal stamp like the control board storage box in such a conventional pachinko gaming machine, the seal stamp can be easily removed without leaving a trace. Therefore, by opening the control circuit board storage case and performing an artificial operation such as attaching the back ROM, a large amount of prize balls are not 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 cause the player to lose by making the fever state hardly occur.

Therefore, if a large amount of prize balls are paid out by a player's cheating, a pachinko parlor will suffer great damage. On the other hand, if the prize balls are not paid out at all due to a fraudulent act on the pachinko parlor side, the player will only waste his money and cannot win. Therefore, 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.

[0006] Further, a pachinko parlor breaks the seal so that a large amount of prize balls can be paid out only to a specific table, and operates the table by pretending to be an insider as a customer. , While aspiring the euphoria of ordinary players, there is a hope that the player will eventually win if he breaks the seal and opens the case to operate so that prize balls are hardly paid out for other machines. While letting it happen, in practice it is possible to let the player go through a table that has no chance of winning at all to lose money. Such illegal use impedes sound economic activities of the gaming industry.

Further, according to the above-described screw for preventing reverse rotation, if the special tool is used, the screw can be turned without breaking the screw, and thus, like the above-mentioned case, no trace is left and the case is not left. It becomes possible to open and open for unauthorized use.

The problem to be solved by the present invention is to make it impossible to open the control board storage box for storing the control board provided on the back surface of the main body of the pachinko gaming machine or the back surface of the game board without leaving a trace, It is an object of the present invention to provide a control board storage box for a pachinko gaming machine that prevents unauthorized use of the pachinko gaming machine.

By inserting one of the insertion pin insertion portions of the cover body toward the other, the insertion pin member is locked by the pin locking member in a non-removable manner. Therefore, even if a person who intends to illegally use the pachinko game machine opens the control board storage box and tries to make a control board, the case body and the cover body are not opened by the sealing means, and thus the traces are left. It cannot be opened without leaving, and unauthorized use will be prevented. Also, by inserting the insertion pin member into the insertion pin insertion portion via the spring member, the insertion pin member is urged by the spring member while being locked by the pin locking member, and the insertion pin insertion The portion and the pin locking member are fixed by the insertion pin member without wobbling.

In this case, in the insertion pin insertion portion, the large-diameter cylindrical portion into which the head portion of the insertion pin member can be inserted and the pin body portion of the insertion pin member can be inserted, and the head portion cannot be inserted. It is preferable that it is composed of a small-diameter cylindrical portion. Then, the head of the insertion pin member is covered with the large-diameter cylindrical portion, and the spring member interposed between the head of the insertion pin member and the small-diameter cylindrical portion,
The insertion pin member is biased in the direction opposite to the insertion direction.

In this case, with the insertion pin member inserted from one of the case body and the cover body toward the other, a large-diameter ring for preventing removal from the pin body of the insertion pin member. You may interpose a member. that way,
At the stage where the insertion pin member is inserted from the insertion pin insertion portion of one of the case body and the cover body toward the other, if a large-diameter ring member is interposed in this insertion pin member, the insertion pin member will It is possible to prevent the pachinko game machine from falling out during the assembly process.
