Abstract

A method of evaluating a stack of currency bills using a currency evaluation device comprising receiving a stack of bills in an input receptacle of the evaluation device. The bills are transported, one at a time, from the input receptacle to one of two or more output receptacles of the currency evaluation device. The denomination of the bill is counted and determined utilizing a detector positioned along a transport path between the input receptacle and the output receptacles. A bill is flagged when the denomination of the bills is not determined and the flagging comprises halting the transporting when a bill is flagged. The bills that have been denominated including bills of a plurality of denominations are delivered to a first set of one or more of the output receptacles.

flagging a bill when the denomination of a bill is not determined;

wherein the act of flagging comprises halting the transporting when a bill is flagged; and

delivering bills that have been denominated including bills of a plurality of denominations to a first set of one or more of the output receptacles.

2. The method of claim 1 wherein the acts of counting and determining the denomination of the currency bills is performed independent of the size of the bills.

3. The method of claim 1 wherein the act of determining of the denomination of bills includes denominating currency bills of a plurality of denominations, bills of at least two of the denominations having the same dimensions.

4. The method of claim 1 wherein the detector includes a stationary optical scanning head, and further including the act of scanning at least a preselected segment of each bill transported between the input and output receptacles along the transport path by the stationary optical scanning head, the act of producing an output signal from the stationary optical scanning head representing the scanned image, and wherein the act of determining of the denomination of each scanned bill utilizes the output signal.

5. The method of claim 1 wherein the at least two output receptacles are exactly two output receptacles.

6. A method of evaluating a stack of U.S. currency bills using a currency evaluation device comprising the acts of:

receiving a stack of U.S. currency bills of a plurality of denominations in an input receptacle of the evaluation device;

transporting the U.S. currency bills, one at a time, from the input receptacle to one or more of at least two output receptacles of the currency evaluation device along a transport path;

counting and determining the denomination of the U.S. currency bills of a plurality of denominations, utilizing at least one detector positioned along a transport path between the input receptacle and the output receptacles;

generating a characteristic information output signal in response to detected characteristic information via the detector;

generating a denomination signal in response to the information output signal;

producing tracking signals in response to the physical movement of the bills;

generating a no call signal when the denomination of a bill is not determined;

generating a stopping signal in response to the no call signal;

stopping a transport drive motor in response to the stopping signal; and

directing the bills which have been denominated to a first set of one or more of the output receptacles.

7. The method of claim 6 wherein the acts of counting and determining the denomination of the currency bills is performed independent of the size of the bills.

8. The method of claim 6 further including the act of generating a scanned pattern from each of the bills based on the characteristic information output signal, the act of determining the denomination of a bill by comparing the scanned pattern generated from the bill with master patterns associated with different denominations of bills, the act of and storing the master patterns.

9. The method of claim 6 wherein the detector comprises an optical scanhead and wherein the scanned and master patterns comprise optical patterns.

10. The method of claim 9 further including the act of correlating the scanned pattern generated from the bill with master patterns associated with different denominations of bills and the act of determining the denomination of the bill if the scanned pattern sufficiently correlates with one of the master patterns.

11. The method of claim 6 wherein the act of determining of the denomination of bills includes denominating currency bills of a plurality of denominations, bills of at least two of the denominations having the same dimensions.

12. The method of claim 6 wherein the act of determining of the denomination of bills includes the act of denominating currency bills of a plurality of denominations, genuine bills of the plurality of denominations having a plurality of images associated therewith, the plurality of images defining the plurality of denominations, and further including the acts of scanning the image associated with each of the bills and distinguishing among the plurality of denominations using the scanned image.

13. The method of claim 6 wherein the at least two output receptacles are exactly two output receptacles.

14. A currency evaluation device for receiving a stack of U.S. currency bills and rapidly evaluating all the U.S. currency bills in the stack, the device comprising:

an input receptacle adapted to receive a stack of U.S. currency bills of a plurality of denominations to be evaluated;

at least two output receptacles adapted to receive the U.S. currency bills after the bills have been evaluated;

a transport mechanism adapted to transport the bills, one at a time, along a transport path from the input receptacle to the output receptacles;

a discriminating unit adapted to count and denominate the U.S. currency bills of a plurality of denominations including bills of a plurality of denominations, the discriminating unit including at least one detector positioned along the transport path between the input receptacle and the output receptacles; and

means for flagging a bill when the denomination of the bill is not determined by the discriminating unit, wherein the means for flagging is adapted to cause the transport mechanism to halt when a bill whose denomination has not been determined is encountered;

wherein the device is adapted to transport bills which have been denominated including bills of a plurality of denominations to a first set of one or more of the output receptacles.

15. The currency evaluation device of claim 14 wherein the discriminating unit is adapted to denominate the bills independent of the size of the bills.

16. The currency evaluation device of claim 14 wherein the currency bills of a plurality of denominations include bills of at least two of the denominations having the same dimensions.

17. The currency evaluation device of claim 14 wherein the detector of the discriminating unit includes a stationary optical scanning head adapted to scan at least a preselected segment of each bill transported between the input and output receptacles by the transport mechanism, and adapted to produce an output signal representing the scanned image and wherein the discriminating unit includes signal processing means adapted to receive the output signal and determine the denomination of each scanned bill.

18. The method of claim 14 wherein the at least two output receptacles are exactly two output receptacles.
