Abstract: A finishing apparatus in a copying machine is disclosed, which can finish large sized papers without enlarging the size of a tray base. The finishing apparatus includes a jogging assembly 170 aligning papers in left and right directions, a paper contact plate 166 provided with a stapler 196, a paper roller 200 pushing the papers to a paper stacker 134, ends of the papers being positioned in the stapler, a tray base 10 moving in a direction opposite to the paper roller to guide alignment of a set of the papers, and an angle adjusting unit guiding the papers by adjusting a tilt angle of the papers in accordance with the size of the papers.

Abstract: An eject mechanism with a grip in a finisher is disclosed, in which papers ejected from a digital output device are temporarily stacked on a paper eject tray and exactly aligned so that the papers are gripped to move to a stacker tray without scattering. The eject mechanism with a grip in a finisher includes a paper eject tray that temporarily receives papers ejected from a digital output device, a paper moving means gripping the papers received in the paper eject tray to move them, and a stacker tray stacking the papers moved from the paper moving means, wherein the paper moving means includes a guide side plate provided with a rail groove circulating along the papers and a curved cam disposed near the rail groove, a paper grip means driven to grip the papers received in the paper eject tray when it is in contact with the curved cam while moving along the rail groove of the guide side plate, and a driving means that drives the paper grip means to circulate it along the rail groove.

Abstract: A tape feeder and a method of controlling the same are disclosed, in which an automatic feeding tape and a manual feeding tape are selectively fed to a binding device.

Abstract: A paper binding system of an image forming apparatus, such as a printer and a copier, and a method for controlling the same are disclosed, in which finishing processes such as stapling and folding are performed by exactly gripping papers ejected from the image forming apparatus without any scattering. The paper binding system of the image forming apparatus includes a paper moving means 150 moving papers ejected from the image forming apparatus, a paper positioning unit 88 temporarily receiving the papers moved from the paper moving means and positioning them, a stapler unit 84 stapling the papers received in the paper positioning unit, a folding means 151 folding the stapled papers, and an eject tray 135 receiving the papers finished through the stapler unit and/or the folding means.

Abstract: Disclosed is a paper processing unit for a binding device that can improve moving efficiency of a sheet of papers and prevent side binding error of the sheet of papers.

Abstract: A stapler moving guide device is disclosed, which can move regardless of a paper conveyer so as to enable multi-stapling at the end of papers and at the same time can move to a side portion at a tilt angle. The stapler moving guide device includes a stapler frame 131 provided with a stapler moving path 133 and a horizontal moving guide 52, a first moving plate 50 reciprocating along the horizontal moving guide, a second moving plate 51 reciprocating on the first moving plate in a direction perpendicular to the horizontal moving guide and moving in parallel with the first moving plate, and a stapler 124 fixed on the second moving plate.

Abstract: A sheet receiving sorting device or mailbox has a sheet infeed including a short, pivoted distributor to direct sheets from the infeed, selectively or in sequence, to the input ends of an array of sheet guides extending at angles radiating from the center of the infeed outwardly to the inlet ends of a vertical stack of trays. At the sheet infeed ends of the trays are drive rolls for carrying the sheets into the trays depending upon the positioning of the distributor with respect to the array of sheet guides. The frame structure enables removal of the guides for sheet jam removal.
