2. Description of the Related Art Generally, a circuit board mounted on a game machine includes a main electronic component such as a CPU and a ROM mounted thereon, as disclosed in, for example, Japanese Patent Application Laid-Open No. 7-88226.
Sealing paper indicating the manufacturer's model name and the approval of a third-party inspection organization is attached. In a board box including a cover member for accommodating the circuit board and a base member, a cover for facing an electronic component of the circuit board is provided so that unauthorized modification such as ROM replacement can be easily found from the outside. It has been practiced to provide a see-through window in a part of the member or to mold the cover member with a transparent or translucent synthetic resin so that the entire cover member can be made a see-through window.

In recent years, in a board box of a game machine, a plurality of joints are formed at portions where the cover member and the base member overlap each other in a closed state, and at least one of the joints is fastened by a fastening member. Inseparable sealing prevents unauthorized opening of the cover member and enables opening for inspection and repair.Since the joint is broken with opening, unauthorized opening can be easily confirmed. Various configurations have been proposed and put into practical use. For example, JP-A-10-286364
