PROBLEM TO BE SOLVED: To provide a game machine capable of externally reporting fraudulent replacement of a main control unit.SOLUTION: When power is supplied to a slot machine 10, an opening/closing frequency command showing the number of opening/closing times of a front door 12 is transmitted from a main control device 131 to a display control device 111. In the display control device 111, it is determined whether the number of opening/closing times stored in an opening/closing frequency counter 186g and that shown by the opening/closing frequency command are the same or not and also whether the opening/closing frequency command can be received or not. In a case when the main control device 131 is replaced by an illegal one and the number of opening/closing times shown by the opening/closing frequency command is different or when the opening/closing frequency command cannot be received, error notification is set. Thus, a possibility of illegal replacement of the main control device 131 can be notified. |
