Abstract

A portable computer having a lid portion pivotally mounted to a body which includes an array of keys. A display section of the lid is aligned, for ease of viewing by an operator, with a subarray of the keys used to display ASCII characters on the display section. For a QWERTY arrangement of keys, a center line of the display section may be aligned, for example, with a line bisecting a row of keys which includes the A through L keys, midway between the F and J keys. The display section and subarray of keys are not aligned with center lines of the lid and body respectively, so that there is more space on one side of the lid adjacent to the display section available for mounting control hardware. The side with more space is used for mounting such hardware as rheostats for adjusting the brightness and contrast of an image on the display section, a back-light arrangement for the display section, an inverter for driving the back-light arrangement, and operation-related indicators.

Dependent claims

A portable computer comprising:

body bound by opposite body sides which are spaced from each other in a longitudinal direction, said body having an array of keys, said array of keys including a subarray of alphanumeric keys whose operation records alphanumeric American Standard Code for Information Exchange (ASCII) characters for display, wherein, for a subarray line perpendicular to said longitudinal direction and symmetrically bisecting said subarray, said subarray line is displaced in said longitudinal direction from a body line perpendicular to said longitudinal direction and symmetrically bisecting said body;
a lid including a display section for displaying the alphanumeric ASCII characters according to signals generated by operation of the keys of said array;
and
a hinge portion connecting said lid with said body for rotation of said lid about an axis which extends in the longitudinal direction, wherein said subarray line, and a display line which is perpendicular to said longitudinal direction and symmetrically bisects said display section, are located in a plane which is perpendicular to said axis, said array comprising a plurality of lines of keys, the lines extending in said longitudinal direction, said subarray consisting of a plurality of the keys in one of said lines, two keys in said one line of keys having position marks formed thereon, the subarray line being equidistantly spaced from said two keys.
