ABSTRACT:
A device for displaying the definition of words listed alphabetically in sequence on a continuous roll of tape. The tape is rolled past a display window between two rollers each linked by a belt to a reversible motor. A cursor is externally slidably mounted on the housing so as to travel under manual pressure transversely to the direction of travel of the tape, with an electrical contact brush internally mounted to the cursor above the tape which makes contact with a metal idler roller under the tape when the cursor is positioned so that the brush passes through a hole in the tape. A hole is located in the tape at the beginning of each set of words of each letter of the alphabet, with the transverse location of such holes corresponding to markings on the housing to which the cursor may be aligned.
