摘要：
A distance measuring device is disclosed. This device has light projecting means. Light is projected from this projecting means to a target, and the concurrently reflected light from the target is received by photoelectric light receiving means which is provided with a plurality of photosensitive elements independent of each other and arranged in such predetermined distances from the above described light projecting means as to correspond to individual object distances different from each other. From the concurrent state of output of said photoelectric light receiving means there can be detected a distance to the above described target.
