Abstract
An optically reading type photo-sensor for reading out an information signal of a signal light with a signal reading light includes a first photoconductor (101) and a second photoconductor (102) interposed between two electrodes (104 and 105); an intermediate region (103) disposed between those two photoconductors for storing and recombining carriers; and an optical source (107) for emitting a signal reading light for uninformalizing the potential in said second photoconductor (102), whereby a successive signal reading can be accomplished without any special preparations for the incidence of the signal light. The photo-sensor can be applied to a variety of imaging devices.
