PROBLEM TO BE SOLVED: To provide a game machine for preventing erroneous insertion of an outside transparent plate and an inside transparent plate. SOLUTION: Since the size of an outside glass pane 52 and an inside glass pane 56 is made different, the outside glass pane 52 and the inside glass pane 56 can be distinguished at the first glance so that the erroneous insertion of the respective glass panes can be prevented. Thus, the antibacterial treatment- applied outside glass pane 52 is not inserted inside so that excess work such as reinserting the once inserted glass pane can be eliminated. COPYRIGHT: (C)2003,JPO
