PROBLEM TO BE SOLVED: To provide a game machine with a mechanism preventing fraudulent opening of a front frame. SOLUTION: A mounting board 15 erected with a support plate 16 is mounted on a free end side rear face of a middle frame. When a knob 51 is upward moved, a front frame locking rod pushing part 52 pushes down a projection part 26 of a front frame locking rod 20 to downward move front frame hook members 21a and 21b, and a front frame is opened from the middle frame. However, when a turning member 60 is positioned below a screw 69 while the middle frame and an outer frame are closed, when the knob 51 is upward moved, a pushing member 54 pushes out a pushed member 64 to turn the turning member 60, a stop member 62 abuts on an impediment wall, or the rear face of a notch in the outer frame to impede the turning of the turning member 60 and an operating member 50. The engagement between the front frame hook members 21a and 21b and the front frame is not released to prevent the opening of the front frame. However, when the turning member 60 is locked above the screw 69, even if the knob 51 moves upward, the pushing member 54 is prevented from abutting on the pushed member 64 and nothing abuts on the outer frame, so that the front frame is opened.
