Abstract
A location detection apparatus is disclosed that includes: a light source; a light output side reflector having a reflecting surface for reflecting light from the light source to a space; a rotation mechanism for rotating the light output side reflector; a first light receiving element for receiving the light reflected from an object existing in the space; a light reception side reflector for reflecting the light from the object to the first light receiving element; a second light receiving element for receiving the light from the light output side reflector; a light conductor for conducting the light reflected from or transmitted through the reflecting surface toward the second light receiving element when the light output side reflector is in a predetermined position; and a rotational position detector that detects rotational position of the light output side reflector based on a detection result of the second light receiving element.
