PROBLEM TO BE SOLVED: To prevent unexpected RAM clear due to erroneous operation of a RAM clear switch for clearing the RAM of a control board in a pinball game machine. SOLUTION: This pinball game machine includes: a clear allow switch 67; and a clear allow signal output means 674 for temporarily outputting a clear allow signal output in response to the on state of the clear allow switch 671 to allow clearing of the RAM when a RAM clear switch 676 is in the on state in advance at the output period of time. Thus, the period of time when the RAM clear switch 671 is effectively operated is limited in turning on the clear allow switch 671. COPYRIGHT: (C)2008,JPO&INPIT
