Abstract

PURPOSE: To simplify the construction of a polarity-detecting circuit by connecting a luminous means of a photo coupler to a diode of polarity opposite thereto and applying a detection signal voltage of non-polarity to said means via a limiting resistance, whereby the polarity can be detected by the presence of the output of a receptor means of the photo coupler.
