<p>PURPOSE:To send and receive signals having no crosstalks irrespectively of the arraying interval of coils even when the number of coils concentrically installed to a rotary transformer is increased, by providing the rotary transformer at the outside of a cylinder. CONSTITUTION:When, for example, reproduced signals are fetched, head chips 36a-36d detect magnetic signals corresponding to prescribed azimuths and the magnetic signals are sent to corresponding coils on a rotor 38 by bundled lines through a repeater base board 35. Since four pieces of coils installed to a stator 52 are respectively electromagnetically coupled to the coils, the magnetic signals are converted into reproduced signal currents and further processed by appropriate reproducing electric circuits provided to a VTR main body by means of lead wires connected with the coils installed to the stator 52. Finally, the signals are sent out from the VTR as video signals. When a rotary transformer is provided at the outside of a cylinder in such a way, video signals can be sent and received without causing crosstalks irrespectively of the arraying interval of the coils.</p> |
