<p>PURPOSE:To obtain a rotary transformer capble of signal transmission in various kinds of signal bands with one rotary transformer, in a rotary transformer to, be mounted as a signal transmission parts of a rotary head cylinder. CONSTITUTION:Inner side magnetic members 8a-8c and outer side magnetic members 9a-9c are constituted of magnetic materials suitable to the respective signal bands of the respective signal transmission systems, and shield rings 14, 15 are interposed between the magnetic members. The above magnetic members 8a-8c, 9a-9c are retained by retainers 16, 17 arranged on the sides opposite to the facing surfaces. By winding coils 12, 13 in winding grooves 10, 11, an excellent rotary transformer capable of various kinds of signal transmission free from signal band limitation is obtained.</p> |
