<P>PROBLEM TO BE SOLVED: To provide a game machine for improving security strength. <P>SOLUTION: A main control unit includes: an output means of outputting a control command; a first generation means of outputting an error inspection value by using the last transmitted control command, on the basis of a generation system determined from among a plurality of generation systems according to the control command output on this time; and a first transmission means of adding the error inspection value output this time to the control command output this time for transmitting to a peripheral unit via an intermediate unit. The intermediate control unit includes: a second generation means of outputting the error inspection value by using the last transmitted control command on the basis of the generation system determined from among a plurality of generation systems according to the control command transmitted on this time; and an inspection means of inspecting validity of the control command transmitted this time by the error inspection value transmitted this time and the error inspection value that a second generation means output this time. <P>COPYRIGHT: (C)2012,JPO&INPIT |
