Abstract

PURPOSE:To realize a new and low-cost circuit which can reduce the number of the optical ccoupling element in case more than four units of the coupling element have to be sued in teh conventional way and more than two units of the elements are not actuated in a time, by giving some contrivance to the control circuit.
