Abstract
Abstract A system for scanning a moving document and displaying a still image of the document without physically impeding the travel of the moving document. The documents, which may contain humanreadable information thereon, are caused to be successively transported past a television camera positioned in a darkened chamber, with the document side containing the readable information oriented towards the television camera. Timed control pulses cause flash lamps, also housed in the darkened chamber, to be momentarily energized, thus bathing the document in a bright flash of light at a time when the document is positioned within the television camera'' s field of view. The light image formed by the document is stored in the form of charged picture elements on the television camera''s light-sensitive screen. These charged picture elements are then electronically scanned for generating video signals, which are stored in a storage device. The stored video signals are subsequently displayed on one of a plurality of television display monitors on a first-in, first-out basis. The readable information is then read by human operators who determine the final disposition of the documents whose image is being currently displayed on a television monitor.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
254 words
A document scanning and display system for presenting images of serially moving documents on a display means and for controlling the disposition of said documents to a document utilization device comprising: an enclosure; an image-capturing device positioned within said enclosure; conveying means for transporting said documents in a direction which traverses the field of view of said image-capturing device while within said enclosure; means for initiating the operation of said image-capturing device, at a time when one of said documents is within the field of view of said device, so that an image of said document is captured by said device; means for generating video signals in accordance with the image captured by said device; storage means for storing said video signals; a plurality of display monitors to receive said video signals and to display thereon the image corresponding to said documents; each said monitor having a keyboard means associated therewith; director control means to route the video signals for a particular document from said storage means to one of said display monitors on a first in - first out basis to enable an operator to indicate on the associated keyboard means, said disposition to be made of the displayed document by depressing a key on the keyboard means to produce a logic signal indicative of that disposition; said director control means having circuit means to receive said logic signal and to switch the video signals for the remaining earliest recorded image from said storage means to an available one of said display monitors.
Claim 2
Dependent Claim
254 words
A document scanning and display system for presenting images of serially moving documents on a display means and for controlling the disposition of said documents to a document utilization device comprising: an enclosure; an image-capturing device positioned within said enclosure; conveying means for transporting said documents in a direction which traverses the field of view of said image-capturing device while within said enclosure; means for initiating the operation of said image-capturing device, at a time when one of said documents is within the field of view of said device, so that an image of said document is captured by said device; means for generating video signals in accordance with the image captured by said device; storage means for storing said video signals; a plurality of display monitors to receive said video signals and to display thereon the image corresponding to said documents; each said monitor having a keyboard means associated therewith; director control means to route the video signals for a particular document from said storage means to one of said display monitors on a first in - first out basis to enable an operator to indicate on the associated keyboard means, said disposition to be made of the displayed document by depressing a key on the keyboard means to produce a logic signal indicative of that disposition; said director control means having circuit means to receive said logic signal and to switch the video signals for the remaining earliest recorded image from said storage means to an available one of said display monitors.
Claim 3
Dependent Claim
49 words
The system as claimed in claim 1 in which said image capturing device is an electronic camera device having a light sensitive screen, and said storage means is a rotating magnetic disc storage means having a plurality of recording channels thereon for storing the video signals of said images.
Claim 4
Dependent Claim
159 words
The system as claimed in claim 2 in which said director control means also comprises: second circuit means for producing a second logic signal indicative of the position of the particular document among said moving documents and for producing a display signal corresponding to the particular one of said display monitors to which the video signals corresponding to the particular document will be sent; and transit memory circuit means; said first named logic signal from said keyboard means and said display signal being used by said director control means to extract from the appropriate channel of said storage means the corresponding video signals and to make the resulting cleared channel available for the entry of video signals of another document; and said first named logic signal and its corresponding second logic signal being transferred to said transit memory means by said directoR control means to provide a bookkeeping track of each document scanned for use by said utilization device.
