PROBLEM TO BE SOLVED: To provide a game machine incapable of performing a game in an abnormal state. SOLUTION: The game machine is provided with an unlocking detection sensor for detecting the unlocking of a locking device and a door opening detection switch for detecting the opening of a front frame or an inner frame, and a main CPU judges whether or not it is fraudulent opening by the input order of an unlocking signal input from the unlocking detection sensor and an opening signal input from the door opening detection switch. In the case of judging that it is the fraudulent opening, the main CPU instructs to stop the putout of game balls by outputting an error signal to a putout control board. COPYRIGHT: (C)2008,JPO&INPIT
