Abstract:
1. An optical position detection device that detects a position of a object optically, comprising: a plurality of light source sections that emit detection light in an emission direction and are separated from each other in a direction crossing the emission direction; a light detecting section that receives the detection light reflected from the object; a light source driving section that turns on the light source sections; and a position detecting section that detects the position of the object on the basis of a light receiving result of the light detecting section, wherein each of the light source sections includes first to third light emitting elements for detection disposed on a straight line, and the position detecting section detects the position of the object using a first detection position, which is obtained when calculating the position of the object using the first and second light emitting elements, and a second detection position, which is obtained when calculating the position of the object using the first and third light emitting elements.
