Abstract
Abstract A copier capable of binding copy papers at their center or their edge as desired. A bookbinding device is operatively connected to a paper outlet of the copier. To bind the papers at their center, a folding mechanism of the bookbinding device is activated first in order to form a crease along the center of each copy paper. Then, a binding mechanism of the bookbinding device is activated to sequentially stack the papers in an upwardly convex form and such that the creases face upward in alignment and, then, stitch the papers together along the aligned creases by means of a staple or the like. The bound papers are discharged to a stacking mechanism of the bookbinding device in a developed position so as to be stacked there while being folded double in the creases. When it is desired to duplicate documents on papers which are equal to or double the size of the documents and bind the copies at the center, a positional relationship between the documents and the papers is set up by a unique method.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
207 words
A copying method for bookbinding which copies documents on papers each being double the size of the documents by means of a copier, comprising the steps of: (a) setting up a relation ##EQU5## where N is a total number of pages of documents and I is a number of papers necessary for copying the N documents pages, and, considering that a front face and a back face of one half of the paper are paged in this sequence, duplicating a page 2i-1 of the documents on a front face of one half of the i-th paper and a page 2i of the documents on a back face of the i-th paper; (b) copying a page 2I of the documents on a back face of one half of a last paper and a page 2I+1 of the documents on a back face of the other half of the last paper; and (c) considering that a back face and a front face of the other half of the paper are paged in this sequence toward the first paper, duplicating a page 4I-2I+1 on a back face of the other half of the i-th paper and a page 4I-2i+2 of the documents on a front face of the i-th paper.

A copying method for bookbinding which copies documents on papers each being double the size of the documents by means of a copier, comprising the steps of: (a) setting up a relation ##EQU5## where N is a total number of pages of documents and I is a number of papers necessary for copying the N documents pages, and, considering that a front face and a back face of one half of the paper are paged in this sequence, duplicating a page 2i-1 of the documents on a front face of one half of the i-th paper and a page 2i of the documents on a back face of the i-th paper; (b) copying a page 2I of the documents on a back face of one half of a last paper and a page 2I+1 of the documents on a back face of the other half of the last paper; and (c) considering that a back face and a front face of the other half of the paper are paged in this sequence toward the first paper, duplicating a page 4I-2I+1 on a back face of the other half of the i-th paper and a page 4I-2i+2 of the documents on a front face of the i-th paper.
Claim 3
Dependent Claim
41 words
A copying method as claimed in claim 1, wherein assuming information are printed horizontally on the documents, the documents are duplicated such that a right half of the paper constitutes the one half and a left half constitutes the other half.
Claim 4
Dependent Claim
41 words
A copying method as claimed in claim 1, wherein assuming information are printed vertically on the documents, the documents are duplicated such that a left half of the paper constitutes the one half and a right half constitutes the other half.
Claim 5
Dependent Claim
51 words
A copying method as claimed in claim 1, wherein documents with information printed vertically are loaded in a document tray of the copier in one top-bottom orientation and documents with information printed horizontally are loaded in the document tray in another top-bottom orientations which is opposite to the first-mentioned top-bottom orientation.
Claim 6
Independent Claim

A method of operating a copier for bookbinding to duplicate a plurality of documents onto a predetermined number of papers which are equal in size to the documents, such that when the papers are bound at a center thereof each of the documents is duplicated in two spread pages of the center-bound papers, said copying method comprising the steps of: feeding a blank paper i into the copier, where i represents one of the papers; duplicating one half of one of the documents d onto one half of a back face of the paper i, where d represents one of the documents; retaining the paper i in the copier; feeding a next paper i+1 into the copier; duplicating the other half of the document d onto one half of a front face of the paper i+1; feeding a last paper of the predetermined number of papers into the copier; duplicating opposite halves of one of the documents onto a back face of the last paper; passing the last paper from the copier; thereafter, duplicating one half of a document onto one half of a face of the retained paper i.
