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.

Head drum assembly for a tape recorder

A head drum assembly of a tape recorder in which an inner race and an outer race of an upper bearing are press-fitted onto a shaft and a rotary drum, respectively, thereby applying a preload. A resilient body, such as a compressed coil spring, is disposed between a lower bearing disposed between the rotary drum and the shaft and a stationary drum. The resilient body upwardly presses the inner race of the lower bearing, thereby applying a preload. Accordingly, the head drum assembly of the tape recorder provides enhanced assembling efficiency and reduced manufacturing costs.

A liquid crystal display module in which a series of overlying sheets can be prevented from wrinkling by fixing the sheets to a mold frame using a fixing member such as the positioner and the earth clips without using the fixing tape and the sheets are provided with an appropriate level of thermal expansion space, thereby eliminating wrinkling. As a result, displaying performance of the LCD device can be significantly enhanced.
