したもので、以下図面について詳細に説明する。The slip ring part of the slave is electrically connected,
Signal transmission was electrical. However, there is a lot of noise in the slip ring part, and electrical signals are easily affected by noise, making it difficult to transmit good signals. In order to solve these drawbacks, the present invention connects slip ring sections optically to perform optical signal transmission, and will be described in detail below with reference to the drawings.

。Light guide 1 is connected to light guide 2 on the stator side of the slip ring.
Each of the ring-shaped members on the rotor side is formed of a material capable of transmitting light and has a rectangular cross section, and is concentrically arranged with the rotation axis of the rotor as the central axis, and is arranged close to each other in the same plane.

ガイド２に入射する。Here, when the rotor is rotating and the rotor and stator are in an arbitrary positional relationship, a signal sent from the optical transmitter 3 on the stator side propagates through the optical fiber 4 and is sent to the light guide 1 via the lens 5. The light enters the light guide 1, exits from the side surface of the light guide 1, and enters the light guide 2.

and a reflecting surface 7 provided on the outer side of the light guide, and propagate through the light guides 1 and 2, and the rotor side is coupled to the light guide 2 with a lens 8. The light enters the optical fiber 9 and is transmitted to the optical receiver 10 on the rotor side. Conversely, when transmitting the title from the rotor side to the stator side, the transmission can be performed in the same manner as above. As described above, according to the present invention, since the signal transmission in the slip ring portion can be performed using an optical signal, there is an advantage that the signal transmission can be performed without being disturbed by noise.
