A gatherer comprises a generally cylindrical bin drum having circumferentially thereon a plurality of inclined shelves spaced apart each other for receiving papers. The gatherer further comprises a paper-size changing body and a switching means for the changing body. The gatherer thus constructed has a number of advantages, such as convenient and rapid introduction and discharge of the papers, accurate alignment of the papers, convenient and simple control of the introduction and the discharge of the papers through rotation direction of the bin drum and applicability to any paper size, as well as high performance with compact and simple construction and so forth.
