Abstract
An electronic apparatus includes a light source that outputs a laser light; a scanning unit that scans the laser light; a reflective member having a reflective surface that reflects the laser light; a light-receiving unit that receives a first reflected light reflected by the reflective member; and a signal processing unit that calculates a distance from the light source to the reflective surface using the first reflected light and determines a direction in which the laser light is output using the distance.
