Abstract:
1. An optical position detecting apparatus that optically detects a position of a target object in a detection region, the optical position detecting apparatus comprising: a light source device that emits position detection light to the detection region and forms an intensity distribution of the position detection light in the detection region; a photodetector that receives the position detection light reflected on the target object; and a position detecting device that detects the position of the target object on the basis of a light reception result in the photodetector, wherein the light source device includes: wherein the linear light source unit includes: each of the first light guide member and the second light guide member includes: the first light guide member and the second light guide member are arranged to face to directions opposite to each other in an extending direction of the linear light source unit and in parallel in a direction orthogonal to the extending direction.
