Abstract

PURPOSE:To reduce the driving electric power of an inputting circuit, by applying an input to a series circuit consisting of a capacitor and a light emission element, and turning on a photothyristor which has been photocoupled by an instantaneous light emission of the light emission element. CONSTITUTION:When an input signal Vi is applied to input terminals Ia, Ib, a charging current (i) of a capacitor C1 flows instantaneously to a circuit consisting of the capacitor C1, the first light emission element LED1, and a diode D1, and the first light emission element LED1 emits light. By this light emission, a photothyristor SCR is turned on. Subsequently, when the input signal Vi comes not to be inputted, the carging current of the capacitor C1 flows to the base of a transistor TR1 through a base resistance R1, and the transistor TR1 is turned on. When it is turned on, the second light emission element LED2 emits light, a phototransistor Ph is turned on, the gate of the photothyristor SCR, and the cathode are short-circuited, therefore, the photothyristor SCR is turned off.
