Abstract

PURPOSE: To provide an optical detector, in which a passage signal of paper or the like by a photoelectric element is integrated and divided by the passing period so that the calulated result may be used as a detected output, thereby making it possible to correctly detect the reflected and transmitted light without any influence from the variation in the transfer speed of the paper.
