Abstract: The present invention relates to an alphanumeric display unit means for improving the identification quantities at selected key buttons of a computer-linked typewriter console through usage of light-emitting indentification indicia attached adjacent to or at the selected key buttons. Each light-emitting display is in matrix format consisting of a set of fiber optic members arranged in orthogonal rows and columns. Encoding is via cooperative drum means including a plurality of rotatable light-emitting diodes (LED's) columnarly aligned at the interior of the drum means for generating a series of light signals for transmission along each set of fiber optic members.
