Abstract

PURPOSE:To prevent the production of malfunction due to external noise and to increase the reliability of power supply operation, by commonly using an optical fiber cable for information transmission for the power supply operation of a terminal device. CONSTITUTION:In a computer system in which a main body device (a) and terminal devices (b1)...(bn) are connected with an optical fiber cable (c), the terminal devices (b1)...(bn) are provided with an optical relay device (d), which photoelectric- converts incoming light and transmits it to a power supply unit (e). The unit (e) closes the switch means of the unit (e) while light is incoming and opens the siwtch means when no light is incoming.
