Abstract

A document feeder comprises an input hopper (1) into which batches of documents with interleaved separators (24, 25) are loaded in use, each separator carrying data related to the associated batch. A feed system (9, 10) withdraws documents and separators singly from the input hopper. A sensing system (7) obtains information about the documents and separators. The sensing system includes a data sensor (7) located so as to read separator data while the separator (24, 25) is in the input hopper (1).

Claims

1. A method of supplying documents from a stack of documents at a storage location, comprising:

stacking a plurality of documents and separators at the storage location with a separator located between successive document batches, each separator carrying data related to the associated batch;

supplying the documents and separators singly from the storage location; and

obtaining information about the documents and separators, including detecting and reading separator data for each separator while the separator is in the storage location.

2. A method according to claim 1, wherein the separator is stationary when the data is read.

3. A method according to claim 1, wherein the documents are supplied from the bottom of the storage location, the separator data being read from underneath the storage location.

4. A method according to claim 1, wherein the separator data is read more than once.

5. A method according to claim 4, wherein the separator data is read at more than one lateral position.

6. A method according to claim 1, wherein the separator data comprises a bar code.

7. A method according to claim 1, wherein the separator data defines a batch number.

8. A method according to claim 1, wherein the information obtained about the documents comprises one or more of authenticity, identification, and size information.

9. A method according to claim 1, further comprising supplying the documents and separators to one of a number of output locations depending on the information obtained about each document and separator.

10. A method according to claim 1, further comprising supplying the documents and separators to the same output location.

11. A method according to claim 1, wherein the documents comprise banknotes or similar documents of value.

12. A method of feeding documents from a stack of documents at a storage location, the method comprising:

detecting one or more characteristics of the document to be fed while the document is in the storage location, the detected characteristic(s) relating to one or more of the authenticity, condition, fitness and denomination or other predetermined pattern of the document; and

supplying the document to a feed system capable of receiving documents only from said stack and in a manner determined in accordance with the detected characteristic(s), the feed system selectively supplying a document to an output stack in accordance with the detected characteristic(s), or each output stack being capable of receiving documents only via the feed system.

13. A method according to claim 12, wherein the document is stationary in the storage location when the characteristic(s) is sensed.

14. A method according to claim 12, wherein the supplying step comprises supplying the document to one of a number of destinations in accordance with the detected characteristic(s).

15. A method according to claim 12, wherein the documents are fed to one of a plurality of output locations selected in accordance with the detected characteristic(s).

16. A method according to claim 12, wherein the documents comprise banknotes or similar documents of value.

17. A document feeder comprising:

a storage location into which batches of documents with interleaved separators are loaded in use, each separator carrying data related to the associated batch;

a feed system for withdrawing documents and separators singly from the storage location; and

a sensing system for obtaining information about the documents and separators, the sensing system including a data sensor located so as to detect and read separator data for each separator while the separator is in the storage location.

18. A feeder according to claim 17, wherein the feed system withdraws documents and separators from the bottom of the storage location, the data sensor being positioned to read separator data when each separator is at the bottom of the storage location.

19. A feeder according to claim 17, wherein the data sensor comprises a scanning beam and a reflectance detector.

20. A feeder according to claim 19, wherein the data sensor scans separator data at more than one lateral position.

21. A feeder according to claim 17, wherein the data sensor comprises an illumination means and a CCD array.

22. A feeder according to claim 17, further comprising a plurality of output locations, the feed system being adapted to feed documents and separators to an appropriate one of the output locations depending on the information obtained by the sensing system.

23. A feeder according to claim 17, further comprising a single output location to which the documents and separators are fed.

24. A document feeder according to claim 17, the feeder forming part of a document counter, sorting assembly or acceptor.

25. A document supply apparatus comprising:

a single storage location for holding a stack of documents;

a feed system for feeding documents only from said single storage location; and

a detector for detecting one or more characteristics of a document, the feed system feeding the document in accordance with the detected characteristic,

wherein the detected characteristic(s) relate to one or more of authenticity, condition, fitness, and denomination or other predetermined pattern of the document, and

wherein the detector includes a sensor located so as to sense the document characteristic(s) while the document is in the storage location.

26. Apparatus according to claim 25, wherein the feed system is adapted to feed documents to one of a number of different destinations chosen in accordance with the detected characteristic(s).

27. Apparatus according to claim 25, wherein the sensor is located so as to view documents through a floor of the storage location.
