PROBLEM TO BE SOLVED: To provide a game machine which facilitates the detection of a fraudulent act and can improve the crime preventing nature. SOLUTION: A lock shaft 13b of a lock lever 13 is pressed to a tooth profile surface of a groove 11b of a hinge member 10 by a coil spring 14 from a closed situation of an inner frame 3 to an outer frame 2 (refer to Fig. 3(a)) to the situation before reaching an opened situation for a certain amount. Even when the inner frame 3 is tried to be closed, the opposed teeth are engaged with each other and the movement of the inner frame 3 in the direction of closing is restricted through the lock lever 13. When the amount of opening of the inner frame 3 reaches the certain amount or more and the direction to apply the reinforcement force to the lock lever 13 by the coil spring 14 is turned around, the engagement of the teeth is lost and the movement restriction of the inner frame 3 to the closing direction is released. Even when the inner frame 3 is tried to be little opened or closed for the fraudulent purpose, the inner frame 3 can be once opened widely without fail and the detection of the fraudulent act can be facilitated.
