Abstract
Abstract A document processor for transporting documents through a path, detecting flaws thereon by electronically scanning each side of the document, printing selectable indicia only on unflawed documents, and sorting and storing separately the flawed and unflawed documents. The electronically scanned information is compared with a master document stored in a computer memory. As a result of this comparison, outputs are provided from the computer which are indicative of a favorable or unfavorable comparison for controlling the printing and sorting functions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
153 words
A document processor, comprising in combination; transport means for moving documents serially along a path including, an impression drum, a transfer drum having a portion of its periphery contiguous to a portion of the periphery of said impression drum, motor means for rotating said impression drum in the clockwise direction and said transfer drum in the counterclockwise direction, singler means for feeding documents serially onto said transfer drum, means for retaining documents on said transfer drum and said impression drum over a portion of their peripheries and for transferring documents from said transfer drum to said impression drum in the contiguous area of their peripheries, flaw detection means disposed adjacent said path for detecting flaws in said documents, printing means disposed adjacent said path for printing selectable indicia on said documents, control means connected to said printing means responsive to said flaw detection means preventing said printing means from printing on flawed documents.
Claim 2
Dependent Claim
153 words
A document processor, comprising in combination; transport means for moving documents serially along a path including, an impression drum, a transfer drum having a portion of its periphery contiguous to a portion of the periphery of said impression drum, motor means for rotating said impression drum in the clockwise direction and said transfer drum in the counterclockwise direction, singler means for feeding documents serially onto said transfer drum, means for retaining documents on said transfer drum and said impression drum over a portion of their peripheries and for transferring documents from said transfer drum to said impression drum in the contiguous area of their peripheries, flaw detection means disposed adjacent said path for detecting flaws in said documents, printing means disposed adjacent said path for printing selectable indicia on said documents, control means connected to said printing means responsive to said flaw detection means preventing said printing means from printing on flawed documents.
Claim 3
Dependent Claim
62 words
A document processor according to claim 1 wherein said flaw detection means comprises; first scanning means disposed adjacent the document path on the periphery of said transfer drum for detecting flaws on one side of said document, second scanning means disposed adjacent the document path on the periphery of said impression drum for detecting flaws on the other side of said document.
Claim 4
Dependent Claim
46 words
A document processor according to claim 2 wherein said printing means comprises; at least one printer disposed adjacent the document path on the periphery of said impression drum at a point on said path after said second scanning means for printing serialized numbers on each document.
Claim 5
Dependent Claim
73 words
A document processor according to claim 3 wherein said control means comprises; edge detector means disposed adjacent the document path on the periphery of said impression drum between said second scanning means and said printer, printer control means, AND circuit means having an output connected to said printer control means and an input from said flaw detection means and said edge detector means for causing said printer to print only on unflawed documents.
Claim 6
Dependent Claim
77 words
A document processor according to claim 4 wherein said printer comprises a drum having a plurality of equally spaced print cylinders disposed about its periphery and, said printer control means includes indexer means for indexing said printer for causing a next print cylinder to be moved into printing position with said impression drum at the same peripheral speed of said impression drum and in synchronism with a document on said impression drum moving into said printing position.
