<p>PURPOSE:To make multi-channel available, by providing a rotor and a stator of magnetic material facing each other through a ring-type toothed surfaces wherein projection parts and recess parts are formed on each peripheral part. CONSTITUTION:When a current corresponding to an information signal to be transmitted to conductors 19 and 20 flows, a magnetic field corresponding to the current is formed by a relation between a rotor 11 and a stator 15 of magnetic material, and a voltage is induced in conductors 22 and 20. Thus the information signal is transmitted between the rotor 11 and the stator 15. The rotor 11 and the stator 15 are arranged in the manner in which a ring-type toothed surfaces (f1) and (f2) are facing. Thus the facing area between the rotor 11 and the stator 15 becomes large, so that multi-channel is available by arranging many conductor on the facing parts.</p> |
