    • The present invention has a configuration is one example in which a second body is connected to be rotatable around a rotational axis to a first body. A light emitting element that emits light and a first light guiding member, which propagates light emitted from the light emitting element as well as irradiating light from an irradiating unit, are housed in the first body. A light receiving element that receives light and a second light guiding member, which lets in light from the light collecting portion irradiated by the irradiating unit as well as propagates light in the light receiving element, are housed in the second body. Complimentary location regions of the irradiating units and light collecting portions are multiply provided between the first light guiding member and the second light guiding member, thereby multiply forming propagating paths of light from the irradiating units to the light collecting portions, respectively.
    • 本发明的结构是将第二主体连接成能够围绕旋转轴线旋转到第一主体的一个示例。 发射光的发光元件和传播从发光元件发出的光以及照射单元的光的第一导光构件被容纳在第一主体中。 接收光的光接收元件和第二导光元件容纳在第二主体中,该第二导光元件使来自照射单元照射的光收集部分的光以及在光接收元件中传播光。 在第一导光构件和第二导光构件之间乘以放射照射单元和光收集部分的免费位置区域,从而将来自照射单元的光的传播路径分别多路复用到聚光部分。
