A document handling system is configured for processing a variety of different documents. The system includes an input receptacle for receiving a stack of documents, a standard sensor for scanning at least one non-color characteristic of the bills in the stack, a color sensor for scanning the color characteristics of the bills, and an output receptacle for receiving the bills after they have been processed. A transport mechanism is included for transporting bills, one at a time, from the input receptacle past the sensors to the output receptacle. An operator interface is provided for displaying information to an operator and inputting information to the system. A processor is also included for processing the data gathered from the sensors to evaluate the bills. |

DETAILED DESCRIPTION In accordance with one aspect of the present invention, there is provided a currency scanning system that uses full color scanning to discriminate and/or authenticate a variety of different currencies, including different denominations within a currency set.
In accordance with another aspect of this invention, there is provided such a currency scanning system utilizing color sensors that eliminate the need for lenses to focus light, thus reducing the cost and size of the system.
In one embodiment, the system of the invention automatically learns the characteristics of authentic currency from a variety of different currency systems.
In accordance with another aspect of this invention, there is provided a document handling system for processing documents, the system comprising a first sensor for scanning at least one characteristic of a document other than color, a full color sensor for scanning color characteristics of the document, and a processor for processing data corresponding to the characteristics scanned from one or more documents with the first sensor and the color sensor and for using the data to evaluate one or more document.
In accordance with another aspect of this invention, there is provided a document scanning system comprising a first scanhead assembly for scanning a first side of a document, said first scanhead assembly including at least one optical sensor for scanning optical characteristics of a document and size sensors comprising a pair of laterally spaced apart linear optical arrays extending a predetermined distance oppositely laterally outwardly for detecting opposite side edges of a document, for determining the length of a document in a direction transverse to a path of travel of a document past said scanhead.
In accordance with another aspect of this invention, there is provided a document handling method for processing documents, the method comprising the steps of scanning at least one characteristic of a document other than color, scanning full color characteristics of the document, processing data corresponding to the color and other characteristics scanned from one or more documents, and using the data to evaluate one or more documents
