Abstract
Abstract A photo-sensor array apparatus comprises an elongated photo-semiconductor substrate, a plurality of elongated upper electrodes arranged on the upper surface of the substrate in the direction of elongation which is identical with the longitudinal direction of the substrate, and a plurality of groups of transparent lower electrodes arranged on the lower surface of the substrate. The respective groups of lower electrodes are associated with the respective upper electrodes so as to be driven in a matrix fashion. Opposing ends of adjacent elongated upper electrodes are spaced a predetermined distance in the transverse direction of the substrate.
