Abstract

PURPOSE:To securely detect paper, etc., by eliminating the influence of outer disturbing electric noise while reducing size by integrally installing a photodetecting element, an amplifier and a binary-coded circuit in a storage body. CONSTITUTION:At a prescribed right-side position on a printed wiring board 11, a photodiode 12 as a photodetecting element is provided. On the right-hand side on the board 11 and around the photodiode 12, an electric circuit 13 which outputs the result of discrimination between light and dark in the form of a binary- coded signal according to the output of the photodiode 12 is incorporated. At the left end part on the board 11, a variable resistor 15 for varying the amplification factor of an amplifier in the electric circuit 13 is provided. The parts of the photodiode 12 and electric circuit 13 on the board 11 are installed in cases 17 and 18 respectively.
