ABSTRACT:
A photoelectric information input apparatus has a photoelectric converting unit including a photoelectric converting layer provided between a linear array of picture element electrodes in a number n and a counter electrode provided in facing relationship to said array and composed of a charge generating portion provided at the side of an electrode transparent to the incident light and of a charge transporting portion for effectively transporting the charge generated in said charge generating portion, said photoelectric converting layer having thickness monotonously changing from an end to the other of said counter electrode. An insulating layer is provided between said photoelectric converting layer and said counter electrode or/and picture element electrodes. There are generated control signals for controlling said photoelectric converting unit so as to obtain electric signals corresponding to the optical signals received by said photoelectric converting portion.
