PROBLEM TO BE SOLVED: To provide a drive unit which can rationally supply power to a fed part provided in a rotator. SOLUTION: It is equipped with rotators 210 and 220, a driving means 300 which rotates the rotators, fed parts 410 and 420 which are provided in the rotators, a ring-shaped coil 500 on the transmission side which is provided in the driving means, ring-shaped coils 510 and 520 on the reception side which are provide in the rotators, and an electric circuit 600 which energizes the coils on the transmission side. The coil on the transmission side and the coil on the reception side are arranged so that the centers may accord with the axis L of rotation of the rotators. It generates induced electromotive force in the coil on the reception side by energizing the coil on the transmission side, and supplies the fed part with the induced electromotive force of the coil on the reception side.
