PROBLEM TO BE SOLVED: To provide a game machine effectively prevented from being fraudulently played. SOLUTION: The game machine has a main controlling section 21 and a power source section 20, and a back-up function which keeps the storage content of the volatile memory of the computer circuit for the main controlling section even after the external power supply stops for the game machine. The power source section 20 forms a system resetting signal SYS indicating the receipt of the external power supply, and a voltage falling signal ANB indicating the falling of the external power supply, and feeds them to the computer circuit. In the meantime, the main controlling section 20 forms a clearing signal CLR corresponding to the ON operation of an initialization switch. In the main controlling section 21, the fact that the initialization switch is under the ON operated state after the storage content of the volatile memory is deleted is determined based on the clearing signal.
