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.

摘要： A projector system includes a projector including a light projection portion projecting an image and a control portion and a light reflector including a mirror portion reflecting light constituting the image projected by the projector to a prescribed region, a drive portion moving the mirror portion, and a position detecting portion capable of detecting the position of the mirror portion. The control portion of the projector is configured to acquire positional information of the mirror portion from the light reflector and switch the image projected by the projector on the basis of the positional information of the mirror portion.

摘要： A position sensing device includes at least one light receiver, and a processor. The light receiver receives lights that are emitted from a plurality of light exit positions of a scanning light source component to scan a predetermined area and are reflected by a sensing object within the predetermined area. The processor controls the scanning light source component, and senses position of the sensing object based on a light reception signal of the light receiver. The processor further determines from which of the scanning lights the light reception signal is obtained, and senses the position of the sensing object based on optical paths of the scanning lights.
