PURPOSE:To perform power supply to an input-output device installed to a remote place from the main body of an electronic computer, by installing a no- break power supplying means, such as a battery, etc., to the connecting device of optical fibers. CONSTITUTION:The main body 1 of an electronic computer is connected to a connecting device 6 through another connecting device 4 and an optical fiber transmission line 5. Only a circuit of the connecting device 6 which receives signals from the transmission line 5 and detects whether an optical signal exists or not, is always set to an operable condition by means of a battery 7. If the connecting device 6 detects an optical signal coming from the transmission line 5 when input-output devices 8a-8n and the connecting device 6 are set to a condition where the AC power supply is cut off, the connecting device 6 performs its own AC power supply and succeedingly issues a turning-on command of AC power supply to the input/output devices 8a-8n. Therefore, power supply to an input/output device installed to a remote place from the main body of an electronic computer can be performed. |
