PURPOSE:To prevent accidents such as the malfunction and destruction of a system without entering dielectric noises into a signal line by making the signal lines between respective devices into optical fiber. CONSTITUTION:An optoelectric input/output device 7 housing an O/E circuit 9 and an E/O circuit 10 in a case is provided on the input or output side of a general purpose processor, a host device, and output equipment. Therefore, the signal lines of the entire device can be made into optical fiber only when the E/O circuit 10 is connected to the output side and O/E circuit 9 is connected to the input side of respective devices. The optical signal can be made into a continuous signal or a pulse signal by a signal conversion circuit 11. Thus, the dielectric noise is not entered into the signal line, and the accidents such as the malfunction of the output equipment, the malfunction or destruction of the host device can be eliminated. |
