    • 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.
    • 本发明的目的是提供一种结构简单且不会导致检测精度下降的光传感器单元。 提供一种光传感器单元,其包括发光元件1和容纳在单元壳体3中的光接收元件2,并且被配置为接收从发光元件1发射到单元壳体3外部的检测光的反射光 与受光元件2一起反射的光从单元壳体3的外部反射。多个发光元件1配置在受光元件2的周围,单元壳体内的反射光的通过空间 3通过适当的隔壁4与单元壳体3内的检测光的通过空间分离。
