Claims

[Claims for Utility Model Registration] (1) A: A plurality of light-emitting elements having mutually different wavelength ranges and supported with their light-emitting surfaces facing the same direction, and B: Light of the wavelengths emitted by the plurality of light-emitting elements. A photoreflector comprising: a light-receiving element capable of receiving light and converting it into an electrical signal and supported with its light-receiving surface facing in the same direction as the light-emitting surface of the upper light-emitting element. (2) A: A plurality of light-emitting elements having mutually different wavelength ranges and supported with their light-emitting surfaces facing the same direction, and B: Each of the light-emitting elements receives light of a different wavelength and converts it into an electrical signal. A photoreflector comprising: a plurality of light-receiving elements;
