Abstract
A video cassette recorder provided with a head drum assembly whose structure is modified to ensure an easy and simple placement of each head base having a through hole and a video head is disclosed. The structure is provided with a rotational drum having through holes, an integral base locating member for locating the head bases beneath the rotational drum, a rotor transformer, and connecting pins for connecting each of the head bases to the rotor transformer. The upper ends and the lower ends of the connecting pins come into contact with a printed circuit board fixed under the head base and electrical contacts on the rotor transformer, respectively.

7280318 - Head drum assembly for a tape recorder - Owned by Samsung Electronics Co., Ltd. (Suwon,KR)

A head drum assembly for a compact-size camcorder such as a digital video camera comprised of a drum cover, stationary and rotating drum, a subcircuit board, a stationary and rotating transformer and a motor stator and rotor. By forming the drum cover, which is attached to the shaft of the rotary drum above the rotary drum, with a conductive material such as an aluminum alloy, the need for a conductive bushing member and earthing plate for the insulating drum cover of the head drum assembly can be omitted, resulting in an overall simpler. As the number of components and manufacturing steps decreases, the manufacturing costs decrease and productivity increases.
