Abstract
PURPOSE:To always obtain the same capacitive coupling state contactlessly by arranging plural pairs of capacitive coupling plates capable of being turned mutually coaxially and transmitting/receiving an electric signal by each couple of capacitive coupling plates. CONSTITUTION:Plural cylindrical capacitive coupling plates 13-10-13-1n are arranged along the center shaft O on the inner circumferential face of the 1st rotary coupler main body 11-1 and plural cylindrical capacitive coupling plates 13-20-13-2n are arranged to the outer circumferential face of the 2nd rotary coupler main body 11-2 at a position opposed to the said capacitive coupling plates 13-10-13-1n. The capacitive couling plates 13-10 and 13-20, 13-11 and 13-21-13-1n and 13-2n are coaxially in pairs to form capacitors. Thus, the same capacitive coupling state is always obtained.
