PURPOSE:To simplify the assembling by making a connection pin formed at a lower face of a lower drum with a circuit pattern of the surface of the base conductive so as to connect the rotary drum electrically without using a cable. CONSTITUTION:Plural connection pins 16 are arranged radially to the rear face of the wiring board 15 mounted to the lower face of the lower drum 11 fitted with a motor 14. A radial circuit pattern 33 corresponding to the pins 16 is formed on a synthetic resin layer 32 on the surface of the chassis 30 and the lower drum 11 and the chassis 30 are coupled by a bolt 40 while clipping a sheet connector 20. The pins 16 and the pattern 30 are conductive and electronic parts such as a magnetic head 13 are connected to the chassis 30 without using any cable, the mounting of the rotary drum device 10 is simplified to constitute the titled device inexpensively. |
