Abstract

This article describes a keyboard having compact size while maintaining the G-type layout. The G keyboard is illustrated in Fig. 1. The keyboard disclosed herein is a compact keyboard, which is a subset of the G keyboard. The compact layout offers small size for systems which require an integrated keyboard or small footprint. The keyboard of this disclosure is shown in Fig. 2. It consists of 85 keys and is capable of generating all of the scan codes of a G keyboard. The keys which are represented are that of a G keyboard without the numeric pad. The Numlock key is added so that the numeric pad functions may be overlaid and used on the compact keyboard. The core of the G keyboard is unchanged, and keys have been grouped and positioned strategically so as to keep it as close to the G layout as possible.

Compact Keyboard Based on "G" Layout

This article describes a keyboard having compact size while maintaining the G- type layout. The G keyboard is illustrated in Fig. 1. The keyboard disclosed herein is a compact keyboard, which is a subset of the G keyboard. The compact layout offers small size for systems which require an integrated keyboard or small footprint. The keyboard of this disclosure is shown in Fig. 2. It consists of 85 keys and is capable of generating all of the scan codes of a G keyboard. The keys which are represented are that of a G keyboard without the numeric pad. The Numlock key is added so that the numeric pad functions may be overlaid and used on the compact keyboard. The core of the G keyboard is unchanged, and keys have been grouped and positioned strategically so as to keep it as close to the G layout as possible.

The compact keyboard is designed for use in a system where the width of the box limits the packaged width of the keyboard to approximately 13 inches in the horizontal dimension. In the vertical, the dimension from the bottom row of keys to the top row of keys is the same as the G keyboard. The keys are standard, and spacing is the standard 19 mm, both horizontally and vertically. The Numlock, Scroll Lock and Caps Lock Keys can have lights in the keys for indicators. The ESC key has a half-high key cap to maintain its remoteness. This will not affect travel or tactile feel. The key labels and graphic symbols are t...
