Claims

[Scope of utility model registration request]

It has an interrupter in which light transmitting parts and non-transmitting parts are arranged alternately, a light source provided on one side of the interrupter, and a pair of light receiving elements provided on the other side of the interrupter. The pair of light-receiving elements are arranged in such a way that when the light-receiving element on the -f side faces the transmission part of the interrupter, the n-side light-receiving element faces the non-transmission part, and the next stage of the light-receiving element is the can light-receiving element. The d-force voltage from the element is input, and the two voltages are compared to output signal 4.
A rotation detector equipped with a voltage comparator.
