Abstract

A system for sorting documents is provided. The system first automatically determines the physical orientation of each document. Each document may have one of the following four orientations: face-forward and right-side-up, face-forward and up-side-down, face-backward and right-side-up and face-backward and up-side-down. Once the physical orientation of each document is determined, each document is sorted by orientation to one of four document bins corresponding to each of the four orientations described above. Preferably, a digital image of each document is captured before being sorted to the appropriate bin, and most preferably, the digital image of each document is automatically oriented to a preferred orientation. Preferably, each document includes visually readable markings, and the physical orientation of each document is automatically determined based upon the visually readable markings. Alternately, it is preferable that each document includes magnetically readable markings, and the physical orientation of each document is automatically determined based upon the magnetically readable markings. The method is particularly well suited to be used with checks and bill heads. In such a case, the physical orientation of the check is determined, and then the check is sorted to an appropriate bin based upon this orientation. The bill head accompanying the check is also sorted to an appropriate bin based upon the check'"'"'s orientation.

Claims

1. A method for sorting documents comprising the steps of:

automatically determining the physical orientation of each document, the physical orientation of each document selected from the group comprising face-forward and right-side-up, face-forward and up-side-down, face-backward and right-side-up and face-backward and up-side-down;

automatically sorting each document by orientation to a document bin selected from the group comprising bin for documents which are face-forward and right-side-up, bin for documents which are face-forward and up-side-down, bin for documents which are face-backward and right-side-up and bin for documents which are face-backward and up-side-down;

capturing a digital image of each document; and

automatically orienting the digital image of each document from a position selected from the group comprising face-forward and right-side-up, face-forward and up-side-down, face-backward and right-side-up and face-backward and up-side-down to a preferred orientation.

2. The method of claim 1 wherein each document includes visually readable markings, and wherein the physical orientation of each document is automatically determined based upon the visually readable markings.

3. The method of claim 1 wherein each document includes magnetically readable markings, and wherein the physical orientation of each document is automatically determined based upon the magnetically readable markings.

4. A method for sorting checks and accompanying bill heads comprising the steps of:

automatically determining the physical orientation of each check, the physical orientation of each check selected from the group comprising face-forward and right-side-up, face-forward and up-side-down, face-backward and right-side-up and face-backward and up-side-down;

automatically sorting each check by orientation to a check bin selected from the group comprising bin for checks which are face-forward and right-side-up, bin for checks which are face-forward and up-side-down, bin for checks which are face-backward and right-side-up and bin for checks which are face-backward and up-side-down;

automatically sorting each bill head by orientation of the check which it accompanies to a bill head bin selected from the group comprising bin for bill heads accompanying checks which are face-forward and right-side-up, bin for bill heads accompanying checks which are face-forward and up-side-down, bin for bill heads accompanying checks which are face-backward and right-side-up and bin for bill heads accompanying checks which are face-backward and up-side-down;

capturing a digital image of each check and accompanying bill head; and

automatically orienting the digital image of each check and accompanying bill head from a position selected from the group comprising face-forward and right-side-up, face-forward and up-side-down, face-backward and right-side-up, and face-backward and up-side-down to a preferred orientation.

5. The method of claim 4 wherein each check includes visually readable markings, and wherein the physical orientation of each check is automatically determined based upon the visually readable markings.

6. The method of claim 4 wherein each check includes magnetically readable markings, and wherein the physical orientation of each check is automatically determined based upon the magnetically readable markings.

7. A method for automatically processing mail, the mail comprising an envelope with a document therein, the method comprising the steps of:

automatically opening the envelope along at least one edge to provide access to the document;

automatically extracting the document from the envelope;

automatically determining the physical orientation of the document, the physical orientation of the document selected from the group comprising face-forward and right-side-up, face-forward and up-side-down, face-backward and right-side-up and face-backward and up-side-down;

automatically sorting the document by orientation to a document bin selected from the group comprising bin for documents which are face-forward and right-side-up, bin for documents which are face-forward and up-side-down, bin for documents which are face-backward and right-side-up and bin for documents which are face-backward and up-side-down;

capturing a digital image of the document; and

automatically orienting the digital image of the document from a position selected from the group comprising face-forward and right-side-up, face-forward and up-side-down, face-backward and right-side-up and face-backward and up-side-down to a preferred orientation.

8. The method of claim 7 wherein the document includes visually readable markings, and wherein the physical orientation of the document is automatically determined based upon the visually readable markings.

9. The method of claim 7 wherein the document includes magnetically readable markings, and wherein the physical orientation of the document is automatically determined based upon the magnetically readable markings.

10. A method for processing mail, the mail comprising an envelope having a check and an accompanying bill head therein, the method comprising the steps of:

automatically opening the envelope along at least one edge to provide access to the check and bill head;

automatically extracting the check and bill head from the envelope;

automatically singulating the check from the bill head;

automatically determining the physical orientation of the check, the physical orientation of the check selected from the group comprising face-forward and right-side-up, face-forward and up-side-down, face-backward and right-side-up and face-backward and up-side-down;

automatically sorting the check by orientation to a check bin selected from the group comprising bin for checks which are face-forward and right-side-up, bin for checks which are face-forward and up-side-down, bin for checks which are face-backward and right-side-up and bin for checks which are face-backward and up-side-down;

automatically sorting the bill head by orientation of the check which it accompanies to a bill head bin selected from the group comprising bin for bill heads accompanying checks which are face-forward and right-side-up, bin for bill heads accompanying checks which are face-forward and up-side-down, bin for bill heads accompanying checks which are face-backward and right-side-up and bin for bill heads accompanying checks which are face-backward and up-side-down;

capturing a digital image of the check and accompanying bill head; and

automatically orienting the digital image of each check and accompanying bill head from a position selected from the group comprising face-forward and right-side-up, face-forward and up-side-down, face-backward and right-side-up, and face-backward and up-side-down to a preferred orientation.

11. The method of claim 10 wherein the check includes visually readable markings, and wherein the physical orientation of the check is automatically determined based upon the visually readable markings.

12. The method of claim 10 wherein the check includes magnetically readable markings, and wherein the physical orientation of the check is magnetically readable markings.
