Abstract: An improved method and apparatus for discriminating between currency bills of different denominations uses an optical sensing and correlation technique based on the sensing of bill reflectance characteristics obtained by illuminating and scanning a bill along its narrow dimension. A series of detected reflectance signals are obtained by sampling and digitally processing, under microprocessor control, the reflected light at a plurality of predefined sample points as a currency bill is moved across an illuminated strip with its narrow dimension parallel to the direction of transport of the bill. The sample data is subjected to digital processing, including a normalizing process, whereby the reflectance data represents a characteristic pattern that is unique for a given bill denomination and incorporates sufficient distinguishing features between characteristic patterns for discriminating between different currency denominations.

Abstract: A currency evaluation device for receiving a stack of currency bills and rapidly evaluating all the bills in the stack. The device comprises an input receptacle for receiving a stack of bills to be evaluated and a plurality of output receptacles for receiving the bills after they have been evaluated. A transport mechanism transports the bills, one at a time, from the input receptacle to one of the output receptacles along a transport path. A discriminating unit including a detector positioned along the transport path between the input receptacle and the output receptacle evaluates the bills. The discriminating unit counts and determines the denomination of the bills. A means for flagging bills meeting or failing to meet a certain criteria causes the transport mechanism to halt in response to a determination that a bill meets or fails to meet the criteria.

Abstract: A method and device for counting and discriminating documents including currency documents comprising a discriminating unit wherein the failure of a bill to be identified by the discriminating unit to causing the operation of the device to be suspended after the unidentified bill has been transported to an examining location for convenient examination by an operator. The device is provided with document-type selection elements. When an unidentified bill is found to be acceptable, an appropriate document-type selection element is chosen. The selection of a document-type selection element causes appropriate counters to incremented and the device to resume operation. The device is also provided with a continuation selection element. Alternatively, when an unidentified bill is found not be acceptable, the document is removed from the output receptacle and the continuation selection element is chosen.

Abstract: An improved method and apparatus for discriminating between currency bills of different denominations uses an optical sensing and correlation technique based on the sensing of bill reflectance characteristics obtained by illuminating and scanning a bill along its wide dimension. A series of detected reflectance signals are obtained by sampling and digitally processing, under microprocessor control, the reflected light at a plurality of predefined sample points as a currency bill is moved across an illuminated strip with its wide dimension parallel to the direction of transport of the bill. The sample data is subjected to digital processing, including a normalizing process, whereby the reflectance data represents a characteristic pattern that is unique for a given bill denomination and incorporates sufficient distinguishing features between characteristic patterns for discriminating between different currency denominations.
