Claims

[Scope of utility model registration request]

a light-emitting element, a lens that focuses light from the light-emitting element, a light-receiving element, a knife edge located immediately in front of the light-receiving element, and an optical axis of the light-emitting element and the lens that coincide with each other, A perpendicular to the light-receiving surface intersects with the optical axes of the light-emitting element and the lens, so that the knife edge is parallel to the light-receiving element, and the edge of the knife edge is parallel to a plane perpendicular to the optical axes of the light-emitting element and the lens. An optical distance sensor comprising: the light emitting element, the lens, the light receiving element, and a holding section that holds the knife edge.
