<p>Provided is a projector that is able to detect the position of an object to be detected, while keeping the structure from becoming complex. The projector (100) is configured in such a manner that the optical axis of a visible light laser beam, which is emitted from first laser beam generation units (61a, 62a, 63a), and of a non-visible light laser beam that is emitted from a second laser beam generation unit (64a) substantially coincide.</p> |
