The light is input to the light receiving side of the light receiving unit 6. Further, the light emitted from the transmission side of the partner light emitting/light receiving unit 6 passes through the transparent cover 11 as parallel light, and passes through the condensing lens 10'.
The light is collected by the light receiving element 8 and received by the light receiving element 8. Note that the driving circuit for the light emitting element 7 and the amplification circuit for the light receiving element 8 may be added to the light emitting/light receiving unit 6 itself, or may be configured as a circuit on the plug-in unit 2.
