Abstract

There is shown and described label bars for use with keyboards when an extended character set (ECS) is available. On printers with this capability, the number of characters far exceeds the number of identification spaces on the key buttons. Fig. 1 is a schematic illustration of the placement of a label bar between rows of key buttons. In one implementation of this concept, depressing a control key and the "F" key causes the printer to print the symbol associated with *2. Fig. 2 is a cross-sectional view of a label bar in position between two rows of keys. The label bar is triangular in cross-section and rests below the surface of the key buttons. This spatial relationship assures that the key bars do not interfere with normal keying action since there is no bind between keys and bars.
