Abstract
A word processing system for displaying and reproducing a plurality of alphanumeric characters on a solid state display and capable of printing from that display consisting of a housing containing an electronic keyboard with indicia markings on the keys. There is provided at least one solid state display device disposed adjacent to the housing and having a multitude of segments for reproducing the indicia identified on the keyboard. A logic means is connected to the keyboard and the solid state display, and scans the keyboard upon the depression of one or more keys to find out the identity of the keys depressed. A solid state memory is also connected to the logic means and contains coded information concerning the keyboard indicia so that a character can be generated and reproduced on the solid state display responsive to the keyed indicia. There is also provided a data storage means for sequentially recording each of the keyed indicia responses provided by the keyboard and a means for printing the indicia displayed on the solid state screen. A plurality of pages of information can be stored in the system and sequentially reproduced by the printer from the electronic display.
