Abstract
A table assembly supports a computer terminal and viewing screen, and keyboard, at a central location for optimum use by a number of users. Separate keyboard-supporting and terminal-supporting tables are independently vertically adjustable. Electrical switches on the keyboard-supporting table are actuated to effect operation of electric motors, which in turn rotate lead screws engaging nuts operatively attached to tubes supporting the tables, and thus effect reciprocation of the tables. The terminal-supporting table is pivoted about a horizontal axis so that the tilt thereof may be adjusted, and the keyboard-supporting table is slideable between detented positions to adjust the position of the keyboard with respect to the terminal and screen. At least one larger side panel, and a rear panel and other panels form the base of the assembly and allow it to be readily integrated with office furniture. Sufficient clearance is provided between all movable and stationary components so that the operator'"'"'s fingers cannot be pinched.
