Abstract

A position detecting apparatus includes a light-transmitting mirror that pivots around a pivot shaft and reflects measuring light from a light source; a light-receiving mirror that pivots around the pivot shaft and reflects returning light from an object; and a light-receiving element that receives the returning light from the light-receiving mirror. When the light-transmitting mirror and the light-receiving mirror are at rest, a first mirror angle between a mirror surface of the light-receiving mirror and a direction from the pivot shaft to the light-receiving element is larger than a second mirror angle between a mirror surface of the light-transmitting mirror and the direction.
