A device wherein object images are formed on photoelectric converter means arranged in the form of a row by a pair of imaging optical systems fixedly disposed with a base line length therebetween and the spacing between the two images is electrically detected to thereby determine the distance to the object, includes a mechanism with which the two images formed by the pair of optical systems can be relatively displaced and regulated in three directions perpendicular to one another and the row-like photoelectric converter means is rotatable about the optical axis of one of the pair of imaging optical systems and in a plane perpendicular to said optical axis. The entire range finding optical mechanism is rotatable about two axes orthogonal to each other.
