<P>PROBLEM TO BE SOLVED: To provide a game machine having a reduced load of control board processing, when a fraud is committed using a radio wave. <P>SOLUTION: Even when an unauthorized radio wave having repeated H and L signals with a short cycle length of 4ms, is applied, once a CPU of a main controller sends a fraud signal to a sub unified controller (fraud flag on), a fraud clear signal (fraud flag off) is not sent during a time T1, so that the load of processing the CPU of the main controller is reduced. The sub unified controller having received the fraud signal notifies of fraud once every time receiving one fraud signal, so that the load of processing a CPU of the sub unified controller is also reduced. Even when the fraud clear signal is received from the main controller, notification operation is extended until a time T2 elapses, and thus even when the unauthorized radio wave is applied for a short time (e.g. one second), the notification operation is executed longer than the length of the time T1 and the time T2, and notification effect is increased. <P>COPYRIGHT: (C)2012,JPO&INPIT |
