GAME MACHINE

PROBLEM TO BE SOLVED: To provide a game machine preventing manufacturing costs from increasing even if a back side of a board case is made visible.SOLUTION: By separating an edge 30A far from a rotation center of a front door 3 in a sub-board case 30 from a board case mount part 3B much more than an edge 30B close to the rotation center of the front door 3 and fixing the edge, the sub-board case 30 is obliquely mounted to the board case mount part 3B, and by opening the front door 3, a back 31 of the sub-board case 30 is made visible, and further a back 8B of a sub-control board 8 provided inside the sub-board case 30 is also made visible. In this case, mount structure for mounting the sub-board case 30 to the board case mount part 3B becomes simple, such that manufacturing costs of a slot machine 1 cannot be increased at all even if the back side of the sub-board case 30 is made visible.
