<p>PURPOSE:To prevent information to be stored and IC elements from being affected by electrostatic destruction. CONSTITUTION:The title device is constructed of an optical input part 4 to which optical signals from each of terminal devices are inputted, an electric signal converter 6 that converts the inputted optical signals into electric signals, an information processing part 7 that processes the inputted electric signals, an optical signal converter 8 that converts the electric signals into optical signals, an optical output part 5 that outputs the optical signals to each of the terminal devices, and an electric power source 9 that supplies electric power to each of the above-mentioned parts.</p> |
