<p>PURPOSE:To make a device small-sized, and also to execute easily an installing work of a rotary drum by connecting a winding of a magnetic head and a winding of a rotor side transformer through a conductive member inserted into plural insulators having rigidity, which is installed to a ring member installed to a rotary part. CONSTITUTION:A repeating substrate 16 fixed to the upper face of a rotor side transformer 7a connects a wire end of a winding of the transformer 7a. A repeating member 17 for connecting a winding of a rotary magnetic head and the transformer 7a is constituted of a columnar insulator 17a having rigidity, which is placed in a hole 18 pierced on a rotary drum 2, a pin 17b which has bent a thin wire made of a metal (copper, etc.) being a conductive member inserted into this insulator 17a, and a thin and cylindrical fitting member (a ring member) 17c which arranges and connects columnary each pin 17b inserted into this insulator 17a and is fitted to a rotary disk 6. When installing the rotary drum 2, the insulator 17a which has a suitable rigidity and also has inserted the pin 17b whose phase relation is determined is made to pass through easily into a prescribed hole 18 of the rotary drum 2.</p> |
