PROBLEM TO BE SOLVED: To provide a game machine, capable of transmitting data from a peripheral substrate to a subsidiary control part in a serial communication path having chain structure, and detecting malfunction such as wire breakage easily and at low cost. SOLUTION: A serial communication part, a first peripheral substrate, a second peripheral substrate, and the serial communication part are loopback-connected. Serial data transmitted are output data including abnormality conforming data, output data, and input blank data. Serial data returned to the serial communication part are abnormality confirming data, output data, and input values. The serial communication part compares the returned abnormality confirming data with the transmitted abnormality confirming data to detect malfunction in a transmission system. By taking out the input values, values transmitted by the second peripheral substrate can be obtained. COPYRIGHT: (C)2011,JPO&INPIT |
