Abstract
Abstract A copying machine is disclosed which is capable of copying an original document having a page number by preliminarily erasing or correcting the page number portion of the image and by changing the order of the output images according to their respective page numbers or by changing the path for delivering the sheet of paper to be copied. A document page image read-in by a charge coupled device sensor is converted into digital signals which are corrected for shading and then binarized and stored in an image memory. This image data is transferred to a working memory wherein the page number shown on the document is read by a page number recognizing unit. The control unit checks the page number and allocates a binding margin on a suitable portion of the document's image. On the basis of the recognition of the page number on the document's image, it also decides to copy the document on one side of the sheet of paper and to deliver it out, or to copy the next document onto the other side of the sheet of paper.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
A copying machine which is capable of copying onto both faces of a paper sheet, comprising a page number recognizing unit for recognizing a page number on an original image, and a control unit which, prior to printing, and according to the recognition made by the page number recognizing unit, adjusts image positioning and thereby defines adequate respective side margins on a top face and a reverse face of each of a plurality of paper sheets to be printed on both faces with images of consecutive pages in such a way that those respective side margins on an even-numbered page and on an odd-numbered page of each paper sheet are arranged in aligned relation to each other, on opposing faces thereof.
Claim 2
Dependent Claim
121 words
A copying machine which is capable of copying onto both faces of a paper sheet, comprising a page number recognizing unit for recognizing a page number on an original image, and a control unit which, prior to printing, and according to the recognition made by the page number recognizing unit, adjusts image positioning and thereby defines adequate respective side margins on a top face and a reverse face of each of a plurality of paper sheets to be printed on both faces with images of consecutive pages in such a way that those respective side margins on an even-numbered page and on an odd-numbered page of each paper sheet are arranged in aligned relation to each other, on opposing faces thereof.
Claim 3
Dependent Claim
68 words
A copying machine which is capable of copying onto both sides of a paper sheet, comprising a page number recognizing unit for recognizing a page number on an original image and a control unit which changes at least one of: the order of the images to be copied and the path for delivering a sheet of paper, according to the recognition made by the page number recognizing unit.
Claim 4
Dependent Claim
68 words
A copying machine which is capable of copying onto both sides of a paper sheet, comprising a page number recognizing unit for recognizing a page number on an original image and a control unit which changes at least one of: the order of the images to be copied and the path for delivering a sheet of paper, according to the recognition made by the page number recognizing unit.
Claim 5
Dependent Claim
76 words
A copying machine as defined in claim 2, further comprising: a memory unit which stores page numbers recognized by the page number recognizing unit and an alarming unit generates an alarm signal when a currently scanned page number coincides with a page number already stored in the memory unit or sequentially scanned original images exceed a capacity of a changing unit for changing a sequence in which images to be copied are output onto said sheet.
Claim 6
Dependent Claim
48 words
A copying machine as defined in claim 2, characterized in that the page number recognizing unit identifies an area containing different color picture elements other than the background and recognizes a pattern of numerals, existing in a convex -bordered portion or an isolated portions as a page number.
Claim 7
Dependent Claim
41 words
A copying machine as defined in claim 2, characterized in that the page number recognizing unit recognizes a pattern of numerals, existing near a position of a signal inputted by an operator through a coordinate input device as a page number.
