ことを特徴とする物体検出装置。[Claims for Utility Model Registration] A light emitting element that projects a light beam, an object that reflects the light beam at the predetermined position by moving to a predetermined position, and a light emitting element that reflects the light beam from the object at the predetermined position. In an object detection device comprising a light receiving element that detects that the object is located at the predetermined position, a concave mirror surface that re-reflects the first reflected light beam from the object at the predetermined position is provided; An object detection device characterized in that the light receiving element is provided substantially coaxially with the light emitting element, facing oppositely to each other, and substantially at the focal point of the concave mirror surface so as to receive the second reflected light beam. .
