Abstract
An object of the present invention is to provide a photosensor lens which, in the case of using a plurality of light emitting elements to form a reflective photosensor, can maximize the efficiency of light irradiation of the light emitting elements with a simple structure. Provided is a photosensor lens configured to condense irradiation light from a plurality of light emitting elementshoused in a unit casein a detection regionoutside the unit case, and to condense reflected light from the detection regionat a light receiving elementin the unit case. A single convex lens surfaceis formed on one side of the photosensor lens, and a light-receiving convex lens surfacesharing an optical axis with the single convex lens surface, and a plurality of light-emitting convex lens surfaceseach having an optical axis in parallel with the optical axis of the light-receiving convex lens surfaceare integrally formed on the opposite side of the photosensor lens.
