Computer Assembly with cam member for locking components

摘要

A computer includes a base unit and an upper unit which encloses all electronic components of the computer, such as an LCD display, system board, various drives, sound card, speakers, and modem. The base unit has dimensions of only about 11 inches by 7 inches and can easily be placed in small areas. Unlike a typical desk-top computer which has external cords or cables connecting the display to a main casing, the computer only requires a single power cable and a telephone cord and has a light weight which permits the computer to be easily transported to different locations. The upper unit can pivot relative to the base unit by simply pulling or pushing the upper unit with one hand to the desired angle and then releasing the upper unit. The base unit frictionally engages the upper unit to maintain the upper unit at the desired angle. The computer has a unique configuration in which input/output connectors of a typical motherboard are placed on a separate riser board positioned perpendicular to the system board. The system board in the computer, consequently, is substantially reduced in size thereby allowing a reduction in the computer's overall size. A CD ROM drive and a floppy drive are installed on opposite sides of the computer and are biased flush against the housing of the computer through a cam assembly. The housing is formed of steel which protects the computer from damage and which also provides EMI shielding both inside and outside of the computer.
