摘要

A currency evaluating device for receiving a stack of currency bills, rapid ly discriminating the bills in the stack, and then re-stacking the bills. The device includes an input receptacle adapted to receive the stack of currency bills to be discriminated, and a transport mechanism adapted to transport the bills in the direction of a narrow dimension of the bills, one at a time, from the input receptacle to a plurality of output receptacles, at a rate in excess of about 800 bills per minute. A discriminating unit is adapted to determine the denomination of each of the bills at a rate in excess of about 800 bills per minute; the discriminating unit including a detector positioned along a transport mechanism path between the input receptacle and one of the plurality of outp ut receptacles adapted to receive and re-stack the bills after being discriminated by the discriminating unit. A method of evaluating currency bills of different denominations using a currency evaluation device comprises receiving a stack of bills to b e evaluated in an input receptacle of the evaluation device; transporting, under control of the evaluation device at a rate in excess of about 800 bills per minute, the bills along a transport mechanism in the direction of a narrow dimension of the bills, one at a time , from the input receptacle to a plurality of output receptacles; and determining the denomination of the bills under control of the evaluation device using a denomination- discriminating unit at a rate in excess of about 800 bills per minute, the discriminating unit including a detector positioned along a transport mechanism path between the input receptacle and one of the plurality of output receptacles adapted to receive and re-stack the bills after being discriminated by the discriminating unit.
