DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board storage box for storing a control board for controlling a game machine such as a pachinko machine or a slot machine.

[0002]

2. Description of the Related Art In a gaming machine such as a pachinko machine or a slot machine, an RO mounted on a control board for controlling the gaming machine is used.
In order to prevent a semiconductor device such as M from being replaced with a semiconductor device such as an illegally modified ROM, various devices have been conventionally devised for a board storage box for storing a control board. In general, the board storage box includes a base on which the control board is mounted, and a lid covering the base. Further, the lid is sealed with respect to the base by sealing means having a required number of sealing portions. In this way, accidental opening of the cover is forbidden, and illegal acts such as unauthorized modification of the control board are prevented. If the lid is accidentally opened and a wrongdoing is performed on the control board, the fact that the sealing part of the sealing means has been damaged is confirmed by the fact that the wrongdoing was performed. Was able to recognize.

By the way, in a state in which the base body and the lid are closed and sealed by a predetermined number of sealing parts, between the base body and the lid, between the adjacent sealing parts. On the other hand, there is a case where a gap is formed between the base body and the lid body by inserting a driver, a metal plate, a wire, or the like, and the ROM is illegally replaced using a tool or the like from the gap. Such a problem is more likely to occur as the size of the substrate storage box increases. In consideration of such problems, the distance between the base body and the lid is reduced by reducing the distance between the adjacent seals and providing a large number of seals. Hard to make a gap in the ROM
It is conceivable to take countermeasures to prevent unauthorized exchange of the information. However, if a large number of sealing portions are arranged at a small interval with respect to the peripheral portion between the base body and the lid, the number of parts increases and the sealing operation becomes troublesome. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a substrate capable of holding a lid in a closed state with a simple structure without a gap with respect to a base body and reducing the number of sealing portions provided. To provide a storage box.
