Abstract
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.
