Photosensor unit with a condensing lens including a plurality of light-emitting convex lens
An object of the present invention is to provide a photosensor unit with a structure which is simple and also does not cause decrease in detection accuracy. Provided is a photosensor unit including a light emitting element 1 and a light receiving element 2 housed in a unit case 3, and configured such that reflected light of detection light emitted from the light emitting element 1 to the outside of the unit case 3 is received with the light receiving element 2, the reflected light being reflected from the outside of the unit case 3. A plurality of the light emitting elements 1 are disposed around the light receiving element 2, and a passage space for the reflected light inside the unit case 3 is separated from a passage space for the detection light inside the unit case 3 by an appropriate partition 4.
