PROBLEM TO BE SOLVED: To provide a game machine, improved in electric discharge efficiency, recycling property and flexibility for frame design. SOLUTION: This pachinko game machine is composed of an outer frame A, an intermediate frame (an intermediate frame b1 and a mechanism frame), and a front frame (a front frame c1 and a glass frame), and the intermediate frame b1 of them is manufactured by die-cast forming an aluminum alloy. As a result, the electric discharge area of the intermediate frame b1 having the mechanism frame provided with various processors and various passages can be secured. The intermediate frame b1 is taken out of a pachinko game machine removed from a game parlor to be reused as forming material for a new intermediate frame b1. Further, the rigidity and shock resistance of the intermediate frame b1 are improved, and the flexibility for frame design can be improved. COPYRIGHT: (C)2004,JPO
