說明書
The four connectors JF1 to JF4 are respective provided with light receivers R1 to R4, each constituted as an RGB color sensor including photodetectors for red (R), green (G), and blue (B). For example, the light receiver R1 is located at a position on the outer circumferential portion of the connector JF1, so as to oppose the light emitter T1 of the connector receiver JM1 when the connector receiver JM1 and the connector JF1 are connected to each other, and configured to receive the yellow light from the light emitter T1. The light receivers R2 to R4 are also located in the same way as the light receiver R1. The light receiver R2 receives the blue light from the light emitter T2, the light receiver R3 receives the red light from the light emitter T3, and the light receiver R4 receives the purple light from the light emitter T4. Hereinafter, the light receivers R1 to R4 may be unspecifically referred to as light receiver R.
