PROBLEM TO BE SOLVED: To provide a game machine which securely detects and prevents a fraud accompanying the opening of a front door. SOLUTION: A blocker device is composed of a door side plate 278 and a case side plate 351 which pass each other when a front door 2 is in a closed state, and a direct acting actuator 352 which penetrates the moving space of the door side plate 278 and can move a movable rod forward to a position where it is sheared by each plate. When the front door is once open the movable rod is moved forward to block the front door closing again. COPYRIGHT: (C)2007,JPO&INPIT
