PROBLEM TO BE SOLVED: To satisfactorily release static electricity which is transmitted to a game machine via a metal portion exposed on its front face. SOLUTION: A conductive member 12 is provided at a position where a lock mechanism 30 for regulating opening/closing of a holding frame 3 is engaged with a main frame 2. A top of a connecting part 123 of the conductive member 12 is abutted to a metallic outer frame. In the state of closing the holding frame 3, the lock mechanism 30 is conductively connected to an outer frame via the conductive member 12. When the static electricity is transmitted to the game machine from the lock mechanism 30 by touching the relevant lock mechanism 30 with a hand of a player or a clerk of a game parlor, the static electricity is released from the neighborhood of the lock mechanism 30 to the outer frame.
