PROBLEM TO BE SOLVED: To provide a game machine for raising crime-preventing performance by facilitating the detection of an illegal action. SOLUTION: The lock axis 13b of a lock lever 13 is pressurized onto the tooth-shape surface of a groove 11b in a hinge member 10 by a coil spring 14 in a state before the closed state of an inner frame 3 with respect to an outer frame 2 (refer to Figure 3(a)) becomes an opening state by fixed amount. Even when the inner frame 3 is desired to be closed, the opposing teeth are engaged, so that the movement of the inner frame 3 in a closing direction is suppressed via the lock lever 13. When the amount of opening of the inner frame 3 becomes not less than the fixed amount and the direction for giving an energizing force to the lock lever 13 is inverted by the coil spring 14, the teeth are disengaged, so as to release suppression with respect to the movement of the inner frame 3 in the closing direction. Even when the inner frame 3 is desired to be opened/closed a little for illegal purpose, the illegal action is easily detected by enabling the inner frame 3 to be temporarily largely opened.
