PURPOSE:To decrease the overall size of the device by making the starting power source capacity at initialization time small and making a cable thin. CONSTITUTION:Each subordinate device is equipped with an electric power supply device 1 consisting of a communication address storage means 3 which stores addresses for communication, a ROM/RAM check means 2 which checks whether or not a ROM and a RAM are normal, a wait time calculating means 4 which calculates a wait time by reading a address for communication out of the communication address storage means 3 according to the check end signal from the ROM/RAM check means 2, a timer means 5 which inputs the wait time from the wait time calculating means 4 and processes the wait time, a mechanism part check means 6 which supplies electric power from a power source part 9 of a main body device 8 to a mechanism part to drive it once a time-out signal is inputted from the timer means 5, checks whether or not the mechanism part is in normal operation, and outputs an initialization end signal to the main body device 8 when the operation is normal, and an alarm means 7 which inputs an abnormality signal from the ROM/RAM check means 2 or mechanism check means 6 and outputs an alarm. |
