Abstract
Abstract An apparatus for storing papers ejected from a copying machine or the like and stapling them after alignment, comprises a contacting member which contacts each paper being transported into a stapling tray to urge the paper for alignment in a specified portion, and a plurality of pressing members for pressing the transported papers at the upper portion thereof against the tray, each of the pressing members is individually adapted correspondingly to the sizes of papers. The contact between the contacting member and the papers is relieved when the stapled papers are discharged from the tray. The pressing members are actuated in conjunction with the paper transporting operation correspondingly to the size of papers. The contacting member is arranged at a location less distant from transport rollers for transporting papers into the tray than the length of paper in the direction of transporting paper on the tray.
