<p>PROBLEM TO BE SOLVED: To provide a game machine for effectively eliminating a fraudulent game.SOLUTION: The game machine has a main control part 21 and a power supply part 20, and includes a backup function for maintaining storage contents of a volatile memory of a computer circuit of the main control part even after external power stops. The power supply part 20 generates a system reset signal SYS showing that the external power is received, and a voltage drop signal ABN showing that the external power drops, and supplies the system reset signal and the voltage drop signal to the computer circuit. On the other hand, the main control part 20 generates a clear signal CLR in accordance with an ON operation of an initialization switch. The main control part 21 determines that the initialization switch is in an ON operation state on the basis of the clear signal after erasing the storage contents of the volatile memory.</p> |
