ABSTRACT:
A banner display device where a plurality of banners are mounted end-to-end to form a scroll which is wound on a pair of parallel and spaced-apart rollers, each driven by a motor. Pulse code modulated drive voltages are produced by microprocessor based command and control circuitry to accurately and efficiently turn the motors at speeds which impart proper tensioning of the scroll during winding.
