Claims

[Scope of utility model registration request]

In a slip ring that exchanges power and electrical signals between the rotating side and the stationary side, the first one is in a relative rotational relationship.
and a second member, a plurality of ring-shaped energizing rings provided on the first member side and made of a conductive material, and a plurality of ring-shaped energizing rings having a larger diameter than the plurality of energizing rings and made of a non-conductor. , a ring-shaped insulating plate disposed on both sides of the energizing ring, the second member being pressed against the cylindrical surface of the energizing ring, and made of the same number of conductive materials as the energizing ring; a plurality of ring-shaped lights having a brush, a transmitting circuit that is provided on the first member side and generates a signal to be transmitted in response to an external input signal, and an optical output surface that outputs an optical signal in accordance with the transmitted signal; a signal generation ring; a ring-shaped tip plate larger than the diameter of the optical signal generation ring and disposed on both sides of the optical signal generation ring;
a number of light receiving elements equal to the number of the optical signal generating rings, which are provided on the second member side, facing the optical output surface of the optical signal generating ring, and arranged at a predetermined distance from the optical signal generating ring; and a receiving circuit that receives the optical signal and converts the output signal into a corresponding electrical signal, and the power is transferred through sliding contact between the current-carrying ring and the brush. A slip ring characterized in that, on the other hand, the transmission and reception of electrical signals is performed by converting the electrical signals into optical signals by the above-mentioned optical-related elements.
