Abstract

Keyboard key buttons are often used for dual purposes. The primary purpose is to cause display of the graphic symbols representing the characters denoted by the specific key button, for example, the upper and lower case designations of an alphabetic character. A secondary purpose of the key button may be to cause a function such as automatic word underscoring to be performed by the system, when the key button is depressed after depression of a keyboard mode changing key button.

Dual Keyboard Graphics

Keyboard key buttons are often used for dual purposes. The primary purpose is to cause display of the graphic symbols representing the characters denoted by the specific key button, for example, the upper and lower case designations of an alphabetic character. A secondary purpose of the key button may be to cause a function such as automatic word underscoring to be performed by the system, when the key button is depressed after depression of a keyboard mode changing key button.

On key buttons 10 and 20 in Figs. 1 and 2, respectively, transparent caps 1 and 2 having primary graphics engraved thereon are attached to the tops of opaque base portions 11 and 21 of key buttons 10 and 20, respectively. Secondary graphics are engraved atop portions 11 and 21 of key buttons 10 and 20, respectively.

In the Fig. 1 embodiment the secondary graphics are engraved on a slanted area of portion 11, while in Fig. 2 the primary and secondary graphics of key button 21 lie in substantially parallel planes. The engraving for the primary and secondary graphics is filled with differing opaque colors to aid the operator in distinguishing the primary and secondary functions of the keys.
