<P>PROBLEM TO BE SOLVED: To improve security strength by a simple means, and also to reduce a processing load on a main control part. <P>SOLUTION: A game machine 1 includes an intermediate control part 180 arranged between the main control part 110 and a peripheral part 300. The main control part 110 includes a transmission part 500 for generating an error inspection value, adding it to a command, and transmitting the resultant command to the intermediate control part 180. The transmission part 500 includes a plurality of error inspection value addition procedures. A main CPU 110 sets a specified procedure among the plurality of addition procedures to the transmission part 500 in booting processing. The transmission part 500 generates the error inspection value of the command generated in the past, and adds the value to the command by the set procedure. Besides, the transmission part 500 changes the procedure when the added error inspection value is a predetermined value. The intermediate control part 180 previously stores the error inspection value for verification, inspects validness of the received command, and then, makes the peripheral part 300 perform processing corresponding to the inspection result. <P>COPYRIGHT: (C)2012,JPO&INPIT |
