发明名称 PROJECTOR
摘要 A projector includes a light scanner, a light detector, a converging lens, and a light guide member. The light scanner is configured to scan light over a projection surface. The light detector is configured to detect reflected light of the light that has been reflected by a detection object. The converging lens is disposed between the projection surface and the light detector to guide the reflected light within a convergence range of the converging lens to the light detector. The light guide member is configured to refract or reflect at least the reflected light outside the convergence range of the converging lens in a widthwise direction parallel to the projection surface in plan view such that the reflected light within a detection range of the projector that is wider than the convergence range in the widthwise direction is guided to the light detector.
