A transmitter side terminal 5 is provided on the grip part, and an ID code memory 18 wherein a receiving side ID code S5 is memory-kept is provided on a receiver R. An ID code transmission circuit 19 is provided on the receiver R, and the receiving side ID code is outputted to an ID code receiving circuit 11 via a receiver side terminal 20 and the transmitter side terminal 5 by the ID code transmission circuit 19. A received receiving side ID code S5 is adopted as a transmission side ID code S1 to be stored in the ID code memory 8 by an ID code receiving circuit 11. |
