发明名称 Optical position detection device and equipment with position detection function
摘要 An optical position detection device includes a first detection light source unit that outputs a detection light from one side to the other side in a first direction, a second detection light source unit that is separated from the first detection light source unit along a second direction crossing the first direction, and outputs a detection light from the one side to the other side in the first direction, a light detection unit having sensitivity toward the other side in the first direction, and a position detection unit that detects the position of the object based on the light reception in the light detection unit.
