Abstract
A partition plate includes a material that blocks transmission of light and partitions an internal space of an enclosure into a light-projecting space where a light projector is disposed and a light-receiving space where a light receiver is disposed. A light shielding plate is configured by a material that blocks transmission of light, is provided between a light-projecting deflector, which is a portion of a deflecting mirror used for light projection, and a light-receiving deflector, which is a portion of the deflecting mirror used for light reception, and integrally rotates with the deflecting mirror. Further, the partition plate has, with respect to at least a part of a peripheral portion of the light shielding plate, an overlap portion where a plate surface of the partition plate and a plate surface of the light shielding plate overlap without being in contact with each other.
