Abstract
A position detection apparatus detects a position of a target object. One end of a swinging member contacts the target object, and the other end contacts a moving member. (M+1) pieces of sensors are arranged to output signals corresponding to a position of the moving member. Measured parts are disposed on the moving member along loci of measuring positions of the sensors. A detection unit detects the position of the target object based on the output signals of M pieces of sensors when the other sensor outputs a predetermined signal. The measured parts corresponding to the other sensor are provided in 2pieces of divided areas that are disposed along a locus corresponding to the other sensor. Each of the measured parts corresponding to the other sensor is disposed in a center portion except both ends in the moving direction in each of the divided areas.
