ABSTRACT:
A sheet dispenser for selectively dispensing predetermined numbers of paper currency of different denominations and having plural stations each receiving a stack of bills. The dispenser includes a feed roller with a pair of flanges. The high friction surface portion of the feed roller flanges engage a bottom sheet and feed it between the feed roller and a stripper shoe to assure single sheet feeding. Elongated acceleration pinch wheels each form a nip with the belt for accelerating a sheet entering the nip. A curved resilient guide cooperates with each feed roller to guide sheets toward its associated nip. The sheets pass along the acceleration belt to an outfeed stacker including a stacker wheel. Sensors detect the entry of a sheet into each acceleration nip and control positioning of the feed roller. Notches in the flanges of each feed roller assure movement of the leading edge of the sheet into the feed nip. Each feed roller rotates one revolution for each sheet to be dispensed. A microprocessor-based electronic control operates the motors to dispense a mix of denominations to preferably minimize the number of bills dispensed. An override is provided to alter the mix of the denominations. In the event that a sensor fails to detect the delivery of a bill to its associated acceleration nip the dispensing operation is automatically repeated at least once.
