Abstract
Abstract A system in which a video camera scans one or more documents and generates analog electrical signals representative of the information on the documents. The signals may be converted to digital signals and stored in a suitable memory from which they may be recalled or they can be used to drive a microfilm or other printer which serves to print a representation of the document. The printer may be controlled so that the new document contains updated information as required, which information can be derived from another document being scanned by an additional video camera or from storage. The stored signals can be selectively recalled from storage, electronically manipulated and applied to the printer to provide a microfilm or print which may include updated information or be in a new format.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
87 words
A document scanning and printing system for producing a printed document having updated information from documents containing information including at least one video camera for viewing the documents containing information and generating an electrical signal representative of the information, means for presenting the documents containing information to said video camera whereby said camera generates said electrical signal, means for processing said electrical signal to generate a new signal having updated information and means responsive to said new signal for producing a printed document having the updated information.
Claim 2
Dependent Claim
87 words
A document scanning and printing system for producing a printed document having updated information from documents containing information including at least one video camera for viewing the documents containing information and generating an electrical signal representative of the information, means for presenting the documents containing information to said video camera whereby said camera generates said electrical signal, means for processing said electrical signal to generate a new signal having updated information and means responsive to said new signal for producing a printed document having the updated information.
Claim 3
Dependent Claim
56 words
A document scanning and printing system as in claim 1 in which said electrical signals and analog signals including an analog to digital converter for receiving said analog signal and generating a digital representation thereof, means for storing said digital representation, and means for receiving from storage selected stored digital representation to form said new signal.
Claim 4
Dependent Claim
21 words
A document scanning and printing system as in claim 2 in which said processing means serve to manipulate said digital signals.
Claim 5
Dependent Claim
29 words
A document scanning and printing system as in claim 2 wherein said new signal includes portions of signals directly from said video camera and portions from said storage means.
Claim 6
Dependent Claim
63 words
A document scanning and printing system as in claim 1 including a plurality of video cameras and a plurality of documents each video camera generating electrical signals representative of the corresponding document and a switching means serving to selectively apply electrical signals from individual cameras to said document producing means whereby to provide said new signal for producing a document including updated information.
