Problems solved by technology
A major obstacle implementing automated currency discrimination systems is obtaining an optimum compromise between the criteria used to adequately define the characteristic pattern for a particular currency denomination, the time required to analyze test data and compare it to predefined parameters in order to identify the currency bill under scrutiny, and the rate at which successive currency bills may be mechanically fed through and scanned.
Even with the use of microprocessors for processing the test data resulting from the scanning of a bill, a finite amount of time is required for acquiring samples and for the process of comparing the test data to stored parameters to identify the denomination of the bill.
Most of the optical scanning systems available today utilize complex algorithms for obtaining a large number of reflectance data samples as a currency bill is scanned by an optical scanhead and for subsequently comparing the data to corresponding stored parameters to identify the bill denomination.
The use of the large number of data samples slows do

Abstract
Abstract of the Disclosure
A currency evaluation device for receiving a stack of U.S. currency bills and rapidly evaluating all the bills in the stack comprises an input receptacle adapted to receive a stack of U.S. currency bills of a plurality of denominations to be evaluated. According to one embodiment, a transport mechanism transports the bills, one at a time, from the input receptacle along a transport path at a rate of at least about 800 bills per minute. A denomination discriminating unit which includes a detector positioned along the transport path evaluates the bills. The device comprises a single denominated bill output receptacle positioned to receive bills whose denomination have been determined by the discriminating unit including bills of a plurality of denominations. A separate stacker bin is provided and a diverter positioned along the transport path routes bills whose denomination cannot be determined to the separate stacker bin.
