摘要： An apparatus (10) for currency discriminating comprising first and second stationary scanheads (18a, 18b), disposed on opposite sides of a bill transport path, for scanning respective first and second opposing surfaces of a bill (17) traveling along the bill transport path and for producing respective output signals. The bill (17) travels along the transport path in the direction of a predetermined dimension of the bill. A memory (34) stores master characteristic patterns corresponding to associated predetermined surfaces of a plurality of denominations of genuine bills. Sampling circuitry (28) samples the output signals associated with the respective first and second opposing surfaces of the scanned bill (17). A signal processor (30) is programmed to determine which one of the first and second opposing surfaces corresponds to the associated predetermined surfaces of the plurality of denominations of genuine bills. The processor (30) then correlates the output signal associated with one of the first and second opposing surfaces corresponding to the associated predetermined surfaces with the master characteristic patterns to identify the denomination of the scanned bill (17).
