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.
