Abstract
Provided is an object detection device which unlikely causes vignetting of a beam reflected from a mirror surface during rotation, and fully ensures object detection performance A light projecting system and a light receiving system are disposed so that a larger one of the area of a region on a mirror surface occupied by a beam emitted from a semiconductor laser and the area of a region on the mirror surface occupied by a beam incident on a photodiode has a longer movement length on the mirror surface during rotation than a smaller one.
