Document filing, updating and retrieval system
First Claim
1. A document storage and retrieval system for filing and updating source documents comprising:
- storage means having a plurality of storage locations, each storage location having first and second storage areas;
filing means for converting the images on a source document to an electronic image signal representative of said images on said source document;
means for generating electronic update signals representative of update information for source documents;
controller means for logically and selectively directing said image signals to said first areas of said storage locations and said update signals to said second areas of said storage locations, the update signals for a particular source document being stored in the same storage location as the image signal therefor;
output means for reproducing source documents from the image signals representative thereof;
means operatively controlled by said controller means for selectively conducting the image signals stored in any said first area of any said storage location to said output means; and
means operatively controlled by said controller means and responsive to said image signals from said conducting means and said update signals from said storage means for selectively mixing the update signals stored in said second area of the same said storage location with said image signals stored in said first area for conduction to said output means whereby said output means reproduces said source document with or without the update information represented by the update signals therefor.

Abstract
A system for filing, updating, and retrieving source documents comprising a video tape recorder; an electro-optic scanner for converting the images on source documents to video signals representative of such images; means for generating update signals representative of update information for source documents; a controller for selectively directing the video signals to first areas of defined storage locations in the video tape recorder and the update signals to second areas of the storage locations, the update signals for a particular source document being stored in the same storage location as the video signals therefor; a monitor for displaying source documents and update information, the controller selectively conducting the video signals stored in any storage location to the monitor; and means controlled by the controller for selectively mixing the update signals for the displayed source document with the video signals therefor for display therewith on the monitor.
