Abstract

PURPOSE:To reduce size, eliminate the influence of an outer disturbing electric noise and further obtain an abnormal signal, by installing a photodetecting element, an amplifier, a binary-coding circuit, and a comparator integrally in a storage body. CONSTITUTION:At a prescribed right-side position on a printed 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. On a left-end part on the board, on the other hand, a variable resistor 15 for varying the amplification factor of an amplifier in the electric circuit 13 is provided. In the electric circuit 13, a comparator for detecting abnormality of a device is provided. An light emitting diode 23 is provided for observing the output state of a binary-coding circuit in the electric circuit 13, and a light emitting diode 24 is for giving the information that the device becomes abnormal.
