ABSTRACT:
A changeable printed alphanumeric display module is disclosed for displaying one character at a time in a viewing window. Each tape of a set of tapes is printed on both front and back surfaces with character segments and is connected between a driving roller and a driven roller in a manner to display one front surface segment and one back surface segment at a time. The tape segments which carry the respective character segments are progressively longer from one end of the tape to the other and the set of tape segments which are displayed together in the window all bear different character segments of the same character so that an entire character is displayed. All tapes in the set are driven in unison to successively present the character segments of each tape in registry with respective window segments.
