ABSTRACT:
A photosensor comprises a first conductive layer formed on a given substrate, a one-dimensional array of a plurality of unit picture elements formed on the first conductive layer to extend in the longitudinal direction thereof, each unit picture element having a photodiode and a blocking diode connected in series with the photodiode in a relationship of reversed rectifying direction therewith, a second conductive layer for connecting together, at one end, respective unit picture elements belonging to each of at least two unit picture element groups having each at least two of adjacent unit picture elements, and a third conductive layer for connecting together, at the other end, corresponding unit picture elements in the respective groups, the set of the photodiode and blocking diode in the respective groups being made of the same semiconductor material. Dispersion of outputs from the respective unit picture elements can be minimized.
