A roll connector is provided with: a light-emitting body and a light-receiving body, the roll connector communicates data between the fixed part and the rotating part by optical communication of the light-emitting body and the light-receiving body; angle sensors provided to the fixed part and/or the rotating part and detecting a relative rotation angle; and a control unit for determining, on the basis of a received optical signal, the data included in the received optical signal. The control unit executes at least one of: changing, according to the relative rotation angle, the data information compared with the received optical signal; correcting the quantity of radiated light according to the relative rotation angle so that the quantity of received light is constant; and correcting the signal level of the received optical signal according to the relative rotation angle so that the signal level of the received optical signal is constant.
