Abstract
A distance measuring circuit controls in a given sequence a distance measuring operation in which a light beam is periodically projected to a target by means of a light projector and reflected light from the target is received by a light receiver, the output signal of which is utilized to determine the distance to the target. When the light projector is not energized, a capacitor is charged by a d.c. source, and discharges to drive the light projector when the light beam is to be projected.
