Abstract

PURPOSE: To ensure a long life time for a luminous element as well as to achieve a digital signal transmission circuit which features an effective reduction of the mistaken information transmission by the circuit, by driving the luminous element with a pulse signal of a repeatitive cycle shorter than the time duration of transmitted pulses.
