<P>PROBLEM TO BE SOLVED: To provide a game machine capable of making each part of the machine appropriately execute movements initially set while avoiding malfunction in energizing a machine power source. <P>SOLUTION: A main control part 21 for controlling game movements centrally and unitedly includes a backup function retaining memory contents of a RAM (Random-Access Memory) even after a cutoff of the power source and a watch dog timer circuit for forcibly resetting a CPU (Central Processing Unit) unless periodically not receiving clear pulses. The CPU of the main control part 21 executes a control program having a system reset processing energized from DC voltage supply and a timer interrupt processing energized in each predetermined time and activates the parts. The clear pulses are repeatedly output to the watch dog timer circuit until the initial processing, which is executed by a sub control part 23 from a start of the DC voltage supply, is completed. Thereby a holding processing ST 5 provided on the system reset processing of the main control part does not shift the movement to the next processing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
