ROTARY HEAD DEVICE

摘要

A rotary head device capable of realizing the highly reliable electrical connection of a rotary transformer with a magnetic head and the installation of the rotary transformer by a simple structure and an easy operation, wherein the communication of signals of the magnetic head (21) installed on a rotary drum (2) supported rotatably on a fixed drum (1) is performed through a rotary transformer rotating side winding (17) installed on the rotary drum (2) and a rotary transformer fixed side winding (18) installed on the fixed drum (1), a circuit board (16) is fixed to the rotary transformer rotating side winding (17) and a holdingly insulated electric conductor (15) is installed on the rotary drum (2), and the electric conductor (15) forms, on one end thereof, a connection piece (15b) allowed to abut on the wiring pattern (22) of the circuit board (16) and energizing the rotary transformer rotating side winding (17) in the direction to press the winding against the installation surface (2a) of the rotary drum (2) and forms, on the other end, a connection piece (15a) allowed to abut on an electrode installed on the magnetic head (21).
