PROBLEM TO BE SOLVED: To provide a rotary connector capable of saving power by suppressing power consumption.SOLUTION: A rotary connector 1 performs communication between a fixed body 8 and a turning body 9 through optical communication making a light-receiving element 22 at a fixed body 8 side receive light from a plurality of light-emitting elements 21 provided around an axis of the turning body 9. The rotary connector 1 obtains rotation speed and a rotation angle of the turning body 9 on the basis of an angle detection signal Sθ output from an angle detection unit 18 and selectively drives the light-emitting element 21 to be driven according to the rotation speed and the rotation angle.SELECTED DRAWING: Figure 1

    【課題】消費電力を抑制して省電力化することができる回転コネクタを提供する。【解決手段】回転コネクタ1は、回動体9の軸回りに複数設けられた発光素子21の光を、固定体8側の受光素子22に受光させる光通信を通じて、固定体8及び回動体9の間の通信を実行する。回転コネクタ1は、角度検出部18から出力される角度検出信号Sθを基に回動体9の回転速度及び回転角を求め、この回転速度及び回転角に応じて、駆動する発光素子21を選択駆動する。【選択図】図1
