A position measuring instrument according to the present invention comprises a turning unit and a fixed unit, irradiates a target to be measured with measuring light to determine a distance, a direction, and a position on the basis of its reflected light. A light source unit emits measuring light; a light receiving unit receives its reflected light; a radiating means radiates measuring light in a direction which can be set freely, and directs its reflected light to the light receiving unit; an angle detecting means detects a direction in which the radiating means radiates light; the light source unit and the light receiving unit are fixedly provided; the light source unit emits measuring light toward the radiating means; and the light receiving unit receives reflected light from the target to be measured.
