Abstract
An optical position detecting apparatus that detects a position of a target object in a detection region, includes: a light source device for position detection that emits position detection light to the detection region and forms an intensity distribution of the position detection light in the detection region; plural photodetectors that direct incident angle ranges to regions not overlapping one another in the detection region; and a position detecting device that detects the position of the target object on the basis of results of detection by the photodetectors of the position detection light reflected on the target object.
