Abstract
PURPOSE:To decrease crosstalk between channels to the large extent, by providing a plurality of concentric grooves in the surfaces of two base boards which face each other and can achieve magnetic shielding, and embedding magnetic core assemblies in said grooves. CONSTITUTION:The base board 14 on the rotating side and the base board 15 on the stationary side are formed by the material which can achieve the magnetic shielding between the channels. In the surfaces of said base boards 14 and 15 which face each other, the concentric grooves 17-20 are carved with an axis 13 as the center. The first magnetic core assemblies 31 and 32 for the first channels are embeded in the grooves 17 and 18. The magnetic core assemblies 33 and 34 for the second channel are embeded in the grooves 1920. In this structure, the magnetic flux, which is generated when a signal current is flowed in the first channel coils 25 or 26, is only the magnetic flux phi11 which contributes to the signal transmission in the first channel. The generation of the magnetic flux which is interlinked with the second channel is approximately perfectly prevented.
