ABSTRACT:
An image input device including a rare gas cold cathode discharge tube is provided to read an irradiated picture image using a photoelectric transducer element. The rare gas cold cathode tub includes a linear tube including a main electrode, an auxiliary electrode and a conductive member connected to the auxiliary electrode for preventing deflections of a positive column formed along the auxiliary electrode. The tube is successively powered on and off. Three of such tubes of different colors may be provided and the irradiated picture image may be read by a storage type photoelectric transducer element.
