Abstract
Abstract An improved banknote stacker is described which achieves reduced levels of jamming and improper stacking. A banknote is directed to a prestorage compartment using a pulley, belt and roller drive assembly. During a pusher cycle, a pusher plate drives the banknote from the prestorage compartment into a banknote storage magazine, and then the pusher plate returns to its original position. Just prior to the pusher cycle, rollers in the roller drive assembly are retracted to release the banknote. The pusher plate is specially designed to prevent banknote slippage, and it is preferably driven by the same drive mechanism which retracts the rollers to insure that a pusher cycle will follow shortly after the retraction of the rollers.
