離測定装置。 A light projecting means for projecting a light beam onto an object to be measured; a light receiving means disposed at a predetermined interval on the side of the light projecting means for receiving reflected light from the object to be measured; It consists of a distance measurement circuit that measures the distance to the object to be measured based on the position of the detected light spot, and a received light level judgment circuit that determines whether the amount of received light is too high or too low. In an optical distance measuring device that outputs an abnormality determination signal output from a signal and received light level determination circuit via an output terminal, a common output terminal is provided to output the distance measurement signal and an abnormality determination signal, and the received light level A signal switching circuit is provided that stops outputting the ranging signal and outputs the abnormality determination signal when the abnormality determination signal is output from the determination circuit,
An optical distance measuring device characterized in that the abnormality determination signal is set to a predetermined voltage outside the voltage level fluctuation range of the distance measuring signal.
