Abstract
Abstract A copying apparatus wherein a document consisting of a first half side and a second half side can be scanned by a scanning member independently corresponding to the area of the first and second half sides. These copies are formed on the both sides of a copy paper or on two different copy papers selectively.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
84 words
A method of copying an original document wherein said original document, placed on an original glass plate, is optically scanned by a movable scanning means, said method comprising: optically scanning a first half side of the original document corresponding to the downstream side in said scanning direction, forming a copy of the first half side on a copy paper, and optically scanning the second half side of the original document independently of said scanning of said first half side to obtain a copy thereof.
Claim 2
Independent Claim
84 words
A method of copying an original document wherein said original document, placed on an original glass plate, is optically scanned by a movable scanning means, said method comprising: optically scanning a first half side of the original document corresponding to the downstream side in said scanning direction, forming a copy of the first half side on a copy paper, and optically scanning the second half side of the original document independently of said scanning of said first half side to obtain a copy thereof.
Claim 3
Dependent Claim
28 words
The method of claim 1, further comprising forming a copy of the second half side on the opposite surface of said copy paper from the first half side.
Claim 4
Dependent Claim
21 words
The method of claim 1, further comprising forming a copy of the second half side on another sheet of copy paper.
Claim 5
Dependent Claim
196 words
A copying apparatus comprising: an original glass plate for supporting an original document, optical scanning means for scanning said document in a scanning direction, a primary scanning mode wherein a second half side of the document corresponding to the upstream side relative to said scanning direction is scanned by said scanning means to obtain a copy of said second half side, and the first half side of the document is scanned by said scanning means which operates independently of the scanning operation for said second half side, to obtain a copy of said first half side after scanning said second half side, a secondary scanning mode wherein a first half side of the document corresponding to said upstream side is scanned by said scanning means to obtain a copy of said first half side, and the second half side of the document is scanned by said scanning means, which operates independently of the scanning operation for said first half side, for obtaining a copy of said second half side after scanning said first half side, and a scanning mode switching means by which one of the primary scanning mode and the secondary scanning mode is selected.
Claim 6
Dependent Claim
196 words
A copying apparatus comprising: an original glass plate for supporting an original document, optical scanning means for scanning said document in a scanning direction, a primary scanning mode wherein a second half side of the document corresponding to the upstream side relative to said scanning direction is scanned by said scanning means to obtain a copy of said second half side, and the first half side of the document is scanned by said scanning means which operates independently of the scanning operation for said second half side, to obtain a copy of said first half side after scanning said second half side, a secondary scanning mode wherein a first half side of the document corresponding to said upstream side is scanned by said scanning means to obtain a copy of said first half side, and the second half side of the document is scanned by said scanning means, which operates independently of the scanning operation for said first half side, for obtaining a copy of said second half side after scanning said first half side, and a scanning mode switching means by which one of the primary scanning mode and the secondary scanning mode is selected.
Claim 7
Dependent Claim
51 words
The apparatus of claim 4, further comprising a switching means for selecting between a whole size copying mode wherein the whole size of said document is copied on one side of a copy paper and a two-paper copying mode which consists of said primary scanning mode and said secondary scanning mode.
Claim 8
Dependent Claim
26 words
The apparatus of claim 5 wherein said copies of said first half side and said second half side are formed on different sheets of copy paper.
Claim 9
Dependent Claim
30 words
The apparatus of claim 5 wherein said copies of said first half side and said second half side are formed on both sides of a single sheet of copy paper.
Claim 10
Dependent Claim
69 words
The apparatus of claim 5, further comprising a copy mode switching means for selecting a primary copying mode wherein said copies of said first half side and said second half side are formed on different sheets of copy paper, and a secondary copying mode wherein said copies of said first half side and said second half side are formed on both sides of a single sheet of copy paper.
