PROBLEM TO BE SOLVED: To provide a game machine and the like in which a sub-substrate immediately allows an error indication to be displayed and an alarm to be sounded to notify people of a fraud act in a hall when a radio fraud act is performed.SOLUTION: In a game machine, a sub control unit receives an internal state signal that is cyclically transmitted, and starts a second timer when receiving the beginning of the internal state signal (or E0H), however, start timing of the second timer is not limited to the time when receiving the beginning of the internal state signal, that is, after the internal state signal is received, the second timer may be started at predetermined timing. If the sub control part receives the internal state signal by time-up (count-down or count-up) of the second timer, it determines that the game machine is normal in order to continue a game, however, if it receives no internal state signal by the time-up, it determines that the game machine is abnormal in order to perform error processing. |
