<P>PROBLEM TO BE SOLVED: To provide a game machine for improving security strength. <P>SOLUTION: A main control part includes: an output means for outputting a control command; a first generation means for generating an error inspection value to inspect validity of the control command; a first determination means for determining, in response to an error inspection value to be transmitted this time, which one of the error inspection values generated by using a control command output last time or a control command output before last time is added to a control command to be transmitted next time; and a transmission means for adding the error inspection value corresponding to the determination of the first determination means to the control command output this time and transmitting them to a peripheral part. The peripheral part includes: a second generation means for generating an error inspection value; a second determination means for determining which one of the error inspection values generated by using the control command received last time or the control command received before last time is used for the next error inspection; and an inspection means for inspecting the validity of the control command transmitted this time through the use of the error inspection value transmitted this time and the error inspection value corresponding to the determination of the second determination means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
