Abstract
Abstract An area of an original document sheet is to be selected for special treatment during reproduction say by an electrophotographic reproduction apparatus. Prior to selecting the area, a copy of the document is made using one type of toner and an image of a grid or other coded pattern is superimposed on this copy using the same or a second type or toner. The second pattern serves as a digitizing grid for use in identifying the area for selective treatment. In one embodiment, the pattern is formed with magnetic toner while the image of the original is reproduced with nonmagnetic toner. Alternatively, the pattern may be formed with operator readable grid coordinates allowing the operator to review the reproduction while away from the copier to determine digitizing inputs that may be manually input. In a second alternative embodiment, the pattern is formed with a different colored toner or a fluorescent toner. A hand held wand is moved over the copy and points identified through pulses generated by displacement of the wand from an edge of the copy or by reading an optical code that is imprinted into the pattern. The wand includes switches allowing the operator to identify types of special treatment etc. as well as memory for storing the points selected. After digitizing of the document is completed, the wand is plugged into the copier and downloaded into the copier's logic and control unit for processing for copying of the original with selective area treatment.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
123 words
In a method of reproducing documents employing a reproduction apparatus, having a function for selective area treatment, by digitizing a document to identify areas thereof for selective treatment by said apparatus, said method comprising the steps of: placing the original to be reproduced upon a support of said apparatus; exposing the original to form a latent image thereof upon a recording element; toning the image to develop the latent image into a visible copy image reproduction of the original; transferring the copy image to a receiver sheet, and characterized by forming a second toner image upon the receiver sheet in register with the copy image, the second toner image defining a pattern for use in digitizing the copy image for selective area treatment.
Claim 2
Dependent Claim
123 words
In a method of reproducing documents employing a reproduction apparatus, having a function for selective area treatment, by digitizing a document to identify areas thereof for selective treatment by said apparatus, said method comprising the steps of: placing the original to be reproduced upon a support of said apparatus; exposing the original to form a latent image thereof upon a recording element; toning the image to develop the latent image into a visible copy image reproduction of the original; transferring the copy image to a receiver sheet, and characterized by forming a second toner image upon the receiver sheet in register with the copy image, the second toner image defining a pattern for use in digitizing the copy image for selective area treatment.
Claim 3
Dependent Claim
54 words
The method of claim 1 and further characterized by the steps of moving a wand over the area of the pattern, the wand creating signal pulses corresponding with movement or the position location over said pattern, and in response to said signal pulses generating data signals indicative of the area selected for special treatment.
Claim 4
Dependent Claim
78 words
The method of claim 2 and wherein the original is placed upon the support, the original is again exposed to form a latent image on the recording element of at least a portion of the image upon the original, and in response to said data signals a selective area treatment is provided during this reproduction of the original and the image of the reproduction is produced with a selective area treatment to differentiate this reproduction from the original.
Claim 5
Dependent Claim
74 words
The method of claim 2 and wherein in the steps of exposing electronic image signals are generated related to image content of at least portions of the original, said image signals are stored in memory and wherein in response to said image signals stored in memory and data signals a latent image of at least a portion of the image of the original is made and a reproduction produced with a selective area treatment.
Claim 6
Independent Claim
23 words
The method of claims 1, 2, 3 or 4 and wherein the selective area treatment comprises erasing a portion of the original image.
Claim 7
Dependent Claim
16 words
The method of claim 5 and wherein the second toner image is formed with magnetic toner.
Claim 8
Dependent Claim
19 words
The method of claim 5 and wherein the second toner image is spectrally distinguishable from the first toner image.
Claim 9
Independent Claim
29 words
The method of claims 1, 2, 3 or 4, and wherein the selective area treatment comprises coloring a portion of the reproduction with a different color than the original.
Claim 10
Dependent Claim
19 words
The method of claim 8 and wherein the second toner image is spectrally distinguishable from the first toner image.
Claim 11
Independent Claim
36 words
The method of claims 1, 2, 3 or 4 and wherein the second toner image is in coded form so that a reading of any point on the pattern itself defines the location of that point.
Claim 12
Dependent Claim
41 words
The method of claim 2 and wherein the wand is unconnected from other devices and stores the data signals in its own memory, the wand thereafter being connected to the reproduction apparatus for downloading the data signals to the reproduction apparatus.
Claim 13
Dependent Claim
90 words
In an apparatus for reproducing documents with selective area treatment; said apparatus comprising: means for reproducing an original document having information thereon with a machine readable pattern in addition to the information present on the original document; means for reading the pattern on the reproduction to define an area selected for special treatment and generating signals in response to said reading; and means responsive to said signals for producing the further reproduction of the original document with the further reproduction differing from the original in accordance with the selected treatment.
Claim 14
Dependent Claim
90 words
In an apparatus for reproducing documents with selective area treatment; said apparatus comprising: means for reproducing an original document having information thereon with a machine readable pattern in addition to the information present on the original document; means for reading the pattern on the reproduction to define an area selected for special treatment and generating signals in response to said reading; and means responsive to said signals for producing the further reproduction of the original document with the further reproduction differing from the original in accordance with the selected treatment.
Claim 15
Dependent Claim
93 words
In an apparatus for reproducing documents with selective area treatment; said apparatus comprising: means for exposing an original to form a latent image thereof upon a recording element; means for toning the image to develop the latent image into a visible copy image reproduction of the original; means for transferring the copy image to a receiver sheet, and characterized by forming a second toner image upon the receiver sheet in register with the copy image, the second toner image defining a pattern for use in digitizing the copy image for selecting area treatment.
Claim 16
Dependent Claim
93 words
In an apparatus for reproducing documents with selective area treatment; said apparatus comprising: means for exposing an original to form a latent image thereof upon a recording element; means for toning the image to develop the latent image into a visible copy image reproduction of the original; means for transferring the copy image to a receiver sheet, and characterized by forming a second toner image upon the receiver sheet in register with the copy image, the second toner image defining a pattern for use in digitizing the copy image for selecting area treatment.
