1. A graphics entry apparatus comprising:
- a case assembly, the case assembly including;
a case top having two spaced-apart apertures; and
a case bottom fixed to the case top to form anenclosure therewith;
a carriage assembly positioned on the case top over a first aperture, the carriage assembly including a graphics entry aperture of predetermined shape which is substantially aligned with the first aperture;
a hand grip mounted to the case top over a second aperture;
means for slideably retaining the carriage assembly on the case top for movement substantially toward and away from the hand grip;
a stylus with a tip;
means acting between the case assembly and the graphics entry aperture for retaining the stylus in the case assembly for sliding two-dimensional movement within the graphics entry aperture;
a first flat, substantially two-dimensional sensing means enclosed in the case assembly for generating graphics input signals in response to movement of the stylus tip, the graphics input signals being indicative of a trace of the movement of the stylus tip on the first sensing means; and
the means for retaining further for retaining the stylus tip in sliding two-dimensional contact with the first sensing means;
second flat, substantially two-dimensional sensing means in the case assembly in contact with the hand grip through the second aperture for generating aperture relocation signals in response to pressure on the hand grip.

Abstract
A graphics input device for use with a graphics processing system includes a stylus which can be manually manipulated by a user to generate graphics input signals representative of a graphics object to be drawn in a circumscribed area on a display device controlled by the graphics processing system. The graphics input device also includes a grip which can be manually manipulated by the user to generate positioning signals for repositioning the circumscribed area on the display.
