Abstract

A text preparation system involving a packaging of the elements of a word processor in a typewriter-like configuration. The system includes a detachable keyboard positioned as in a conventional typewriter with the printer set on an angle so that the user can observe the positioning of the paper as is necessary when filling in preprinted forms. An electronic memory and video display unit are provided which allow text storage and editing prior to printing. The video display is supported by an articulated arm and the position and attitude of the video display can be locked using a single clamp.

Claims

1. In a text preparation system which includes a keyboard, electronic processing circuitry, a printer, and video display means, the improvement which comprises:

an enclosure for containing said electronic processing circuitry, said enclosure having a sloping top for holding said printer whereby an operator may view the printing function of said printer while seated in position to operate said keyboard, said enclosure having a keyboard support for supporting said keyboard at a predetermined height; and

means for movably supporting said video display means whereby said video display may be positioned at a convenient location and angle with respect to the operator comprising a vertical post mountable at any one of a plurality of positions adjacent said enclosure;

an arm rotatably mounted to the top of said post;

means for mounting said video display at the free end of said arm;

means limiting the rotation of said video display in a horizontal plane; and

means for rendering the limits of said rotation of said video display relative to said arm dependent on the position of said arm, said means for rendering the limits of rotation of said video display dependent on the position of said arm comprising a train of gears coupling said post to said rotation limiting means.

2. A text preparation system improvement as recited in claim 1 and further including clamping means for simultaneously preventing rotation of said video display and one of the gears in said term of gears relative to said arm.

3. A text preparation system as recited in claim 1 and further including locking means for preventing the rotation of one of the gears in said train of gears with respect to said arm whereby the rotation of said arm with respect to said base unit is prevented.

4. A text preparation system as recited in claim 3 where said locking means also prevents the rotation of said video display unit with respect to said arm.
