Electronic typewriter having an electronic display

Abstract

Abstract A word processing system for displaying and reproducing alphanumeric characters on a photocopy machine capable of scanning an original document, having a housing including an electronic keyboard with keys representing individual alphanumeric characters, the housing including a display for viewing a portion of the information keys, and a memory circuit coupled to said keyboard for storing and spacing the alphanumeric indicia in memory. A microprocessor circuit, having an algorythm circuit, is coupled to the memory circuit for converting the stored alphanumeric indicia from the memory to a line of dots by comparison with the algorythm circuit; and at least one elongated, solid state reflective display strip, having a single line of reflective dots defining its display screen, is disposed transversely to the scanning direction of the photocopy machine, the strip being coupled to the microprocessor, the microprocessor addressing the proper column of dots in a row to produce the top portion of a complete line of alphanumeric characters on the screen, addressing the same column of dots in the next sequential row, so that the top portion of the characters are shifted one space up to display the adjacent lower portion of the character line on the screen, so that, after a plurality of addressing cycles, the stored alphanumeric indicia, which are converted to a line of dots and reproduced on the screen, are scrolled synchronously in the same direction and at the same speed as the scanning speed of the photocopy machine.
