PROBLEM TO BE SOLVED: To provide a compact device performing energy transmission and data transmission, in non-contact, between two objects rotating relatively around the axis of rotation, and strong to noise.SOLUTION: A device includes circular or arcuate first and second coils 14, 114 facing each other in the axial direction of the axis of rotation A, and performing energy transmission by induction coupling, and circular or arcuate first and second conductors 12, 112 provided coaxially with the first and second coils 14, 114, and facing each other while separated in the axial direction, and performing data transmission by electrical coupling. The carriers of the first coil 14 and first conductor 12 and of the second coil 114 and second conductor 112 are constituted, respectively, as integral wiring boards 10, 110. Between the first coil 14 and conductor 12 and/or between the second coil 114 and conductor 112, placement products 18, 118 composed of a conductive material are installed, and through holes 20, 120 formed in the wiring boards 10, 110 are filled with a conductive material.SELECTED DRAWING: Figure 1 |
