In an optical encoder, an output signal of the encoder and a signal inverted from the output signal are respectively inputted to one input terminal and the other input terminal of a comparator constituting a circuit for electrically decomposing the output signal of the encoder, whereby it is possible to obtain a highly accurate electrical division circuit which is capable of removing the hysteresis of a comparator, noises and D.C. offset.
