Computer terminal including multi-position attached keyboard
First Claim
1. A computer terminal, comprising:
- a frame;
a keyboard; and
support means for supporting the keyboard for movement relative to the frame including rotational movement about an axis which is transversely movable in a direction perpendicular to itself;
including;
a shaft which rotatably supports the keyboard coaxially with said axis and has opposite end portions which extend from the keyboard; and
a pair of guide units for rotatably supporting and guiding said end portions of the shaft respectively for transverse movement in said direction, each of the guide units including;
a rack which extends in said direction and has a toothed surface;
two pinion gears which are spaced from each other in said direction and mesh with said toothed surface of the rack;
a carrier which is rotatably supported by the pinion gears and rotatably supports one of said end portions of the shaft; and
a gear which is fixed to said one of said end portions of the shaft end meshes with one of said pinion gears.

Abstract
An upright wall mountable or portable computer terminal (10) includes a keyboard (16) which can be moved to a number of locked positions, including stowed (flat) for fingerpoking, extended out in a typing position, lowered, angled and flipped over with the keyboard (16) inside. The keyboard (16) is supported by a mechanism (20) which extends from a frame (22) of the terminal (10) and includes a shaft (40) which rotatably supports an upper edge portion of the keyboard (16). Rack and pinion units (24) rotatably support the ends (40a) of the shaft (40) and enable rotation and up and down movement of the shaft (40) and thereby the keyboard (16) without skewing. A spring loaded latch (70) enables the keyboard (16) to be locked in a desired position with overforce breakaway.
