Abstract

PURPOSE:To cause no trouble although some power supply has no working in a system, by supplying the electric power to all electronic devices from the working electronic device and by the operation of one of plural electronic devices forming a system. CONSTITUTION:It is supposed with a communication system comprising plural electronic devices that a power supply device 21 of an electronic device becomes inactive to discontinue the supply of power via a feeder 25 to an input/output device 17 and a signal processor 18. In such case, the power supply is possible to the device 17 via a power supply bus 26 and a diode 24 as long as at least one of other power supply devices in the system is working. Thus the power is supplied to the device 17 although the device is inactive to continue the transmission of signals.
