An incremental encoder has a rotor provided with a plurality of indices and is capable of detecting a reference point or a zero point without turning the rotor one full turn. Graduation lines of a main scale are counted until a detector detects an index I.sub.1 and the next index I.sub.2, the angle or the distance between the reference point and the index I.sub.2 is determined on the basis of the counted number of graduation lines of the main scale, the angle or the distance between the position of the index I.sub.2 and an optional position is determined on the basis of the corresponding number of graduation lines of the main scale, and the angle or the distance between the reference point and the optional position is determined by adding the angle or the distance between the reference point and the position of the index I.sub.2 to the angle of the distance between the position of the index I.sub.2 and the optional position.

The present invention relates to a position measuring instrument for, for example, scanning a photoreceiver as a target to be measured, and more particularly to an automatic position detection instrument capable of emitting distance measuring light and tracking light while turning directions of the distance measuring light and the tracking light so that three-dimensional measurement of a light receiving position is performed, and further capable of transmitting measured data to a photoreceiver provided on a target. A light source unit emits measuring light, and then a light receiving unit receives its reflected light. A scanning means emits measuring light in a scanning direction, and leads its reflected light to the light receiving unit. An angle detector detects a rotational position of the scanning means. The measuring light includes distance measuring light expanding in a fan-shaped manner. Its reflected light can be used to measure a distance to a reflector.
