Abstract
Abstract A finisher for an image forming apparatus for stapling or otherwise finishing paper sheets which are sequentially driven out of an image forming apparatus such as a copier or a printer. The finisher is capable of stapling a stack of paper sheets at any desired position or positions of the sack. A pair of reference fences and a pair of jogger fences are provided on a paper receiver for positioning paper sheets in an intended direction of paper transport and a direction perpendicular thereto, respectively. The reference fences and the jogger fences are reciprocatingly movable in a predetermined direction independently of each other, and each is movable in a symmetrical relation. The jogger fences move independently of a stapler, while the reference fences move along with the stapler by being connected to latter.
