Abstract

A temporary display is used in association with a word processing system to facilitate justification, decimal tab, centering and flush right functions. The temporary display provides sufficient visual feedback to the operator to perform the required function prior to printing out a correct copy, thereby eliminating the need to print a second correct copy.

Temporary Display for Word Processing System

A temporary display is used in association with a word processing system to facilitate justification, decimal tab, centering and flush right functions. The temporary display provides sufficient visual feedback to the operator to perform the required function prior to printing out a correct copy, thereby eliminating the need to print a second correct copy.

Various forms of temporary display can be utilized. For example, a continuously moving character tape 11 can be located immediately above the keyboard of the system. Tape 11 has a successive set of symbol representations 12 and a set of grating lines 13 thereon. Motor 15 effects motion of the tape.

The tape 11 moves within a channel defined by light support 17 and mask 19. A bank of light-emitting diodes 21 are located immediately behind tape 11 and are strobed with the appropriate grating signal so as to illuminate a selected character. The mask 19 is located in front of the moving tape so that the illuminated character appears in the window of the mask.

As each character is keyed, it is stored in a memory device. The memory device causes the character to be displayed on the temporary display. Once a line of characters has been keyed, and the appropriate decision has been made by operator indication of a line ending point, a signal may be transmitted to the word processor causing the word processor to appropriately justify, flush right, or center the text in a conven...
