<P>PROBLEM TO BE SOLVED: To provide a game machine capable of effectively excluding an illegal game, and of accommodating abnormality of a random number generation circuit properly and rapidly. <P>SOLUTION: A watchdog timer 63 includes: a self-propelled oscillation part outputting an alarm pulse at a prescribed period in a self-propelled state; and an avoidance input part returning the operation of the self-propelled state of the self-propelled oscillation part to an initial state when receiving an avoidance signal from the MSB of a counter before the output timing of the alarm pulse. A reset circuit includes a logic circuit receiving the alarm pulse of the watchdog timer 63 and a permission signal CTL indicating whether or not it is in a reset permission state, and outputting the alarm pulse as a reset signal when it is in the reset permission state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
