Claims

[Claims for Utility Model Registration] 1. A current collector ring that rotates integrally with the rotating shaft, a brush that makes sliding contact with the outer peripheral surface of the current collector ring, and a terminal connected to one end of the brush that is fixed. In a slip ring that consists of a fixed case and continuously electrically connects a current collecting ring and a terminal, the rotating shaft is extended to the opposite side from the mounting side, and a position detection sensor is provided on this rotating shaft. A slip ring characterized by: 2. The position detection sensor is made up of a rotary plate with radial slits on the rotating shaft extending to the side opposite to the mounting side, a light emitting element fixed to the end face of the fixed case so as to sandwich the slit part of this fixed plate, a fixed plate, and a light receiver. 2. The slip ring according to claim 1, wherein the slip ring is constituted by an element. 3. Claim 1, wherein the position detection sensor is constituted by a magnetic recording rotating drum fixed to a rotating shaft extending to the side opposite to the mounting side, and a magnetoresistive element fixed to the end surface of the stationary case opposite to the mounting side. Slip ring as described.
