Patent number: 7556260Abstract: An image forming apparatus includes a driving roller for transporting a medium; a follower roller disposed to face the driving roller for transporting the medium; a guide member for guiding the medium to change a transport direction thereof by an angle greater than 30°; and a rotational member disposed to be freely rotatable at a position corresponding to a side edge of the medium. Accordingly, after the driving roller and the follower roller transport the medium, when the medium contacts with the guide member, side edges of the medium contact with the guide member at an angle smaller than that of a center portion of the medium contacting with the guide member.Type: GrantFiled: September 27, 2007Date of Patent: July 7, 2009Assignee: Oki Data CorporationInventors: Satoshi Yoshimoto, Takahiro Sunohara

Publication number: 20090121414Abstract: An image forming device, which is configured to form an image on a sheet, includes a main body casing, a catch tray provided on the main body casing to be loaded with the sheet discharged in a first direction with the image formed thereon, and a cover configured to cover a downstream-side face of the main body casing in the first direction in an openable and closable manner. The catch tray is disposed such that a downstream-side end thereof in the first direction faces an upstream-side end of the cover in the first direction. The downstream-side end of the catch tray and the upstream-side end of the cover are configured to mutually overlap when viewed in a second direction perpendicular to the first direction and a vertical direction.Type: ApplicationFiled: November 6, 2008Publication date: May 14, 2009Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventor: Sakae ITO

Patent number: 7494121Abstract: A system and method of stacking printed sheets with sheet curl stacking problems in an automatically variable configuration stacking system having a spaced array of repositionable initial sheet supporting surfaces providing a generally planar initial stack supporting configuration on which a limited amount of sheets initially stack, and then, in response to stacking additional sheets in said system, the stacking system automatically changes to a different, arcuate, stack supporting configuration by automatically lowering at least some of the spaced array of initial sheet supporting surfaces to arcuately bend the curled sheets in an arcuate direction transverse the sheet curl direction on a fixed stacking surface that is arcuate transversely of the sheet curl direction.Type: GrantFiled: March 7, 2006Date of Patent: February 24, 2009Assignee: Xerox CorporationInventors: Douglas K. Herrmann, Richard P. Ficarra, Tina M. Burns, Bruce D. Caryl, Robert F. Rubscha

Patent number: 7484729Abstract: An image forming apparatus includes a loading portion that is capable of receiving a recording sheet. The loading portion includes a correction member which has a bending portion, wherein the bending portion selectively moves between a first position and a second position, the second position being located higher than the first position, and a stopper that selectively moves between a closed position and an open position in which the stopper extends upward at a predetermined angle with respect to a horizontal surface when the stopper is at the open position.Type: GrantFiled: December 7, 2004Date of Patent: February 3, 2009Assignee: Brother Kogyo Kabushiki KaishaInventors: Akehiro Ono, Masahiro Kamimura

Patent number: 7464925Abstract: According to an aspect of the invention an adjustable sheet feeder for use in an apparatus for feeding sheets from the top of a sheet supply stack is shown. The sheet supply stack has a center and marginal edges, each having a top. The adjustable sheet feeder comprises a sheet supply stack support, a sheet feed head assembly, a curl sensing device which senses the position of the stack edges relative to the position of the stack center top and provides feedback, an adjustment device, and a feed back display which displays the curl sensing device feedback. The adjustment device adjusts the position of the stack center top relative to the position of the stack marginal edges top based on the curl sensing device feedback.Type: GrantFiled: February 11, 2005Date of Patent: December 16, 2008Assignee: Eastman Kodak CompanyInventors: Michael T. Dobbertin, Alan E. Rapkin

Patent number: 7461841Abstract: Disclosed is a sheet discharging apparatus in which an apparatus main body portion is provided with plural discharging rollers for discharging sheets by rotation, and a shaft coaxially fixed to the discharging rollers. The shaft has an outer diameter smaller than an outer diameter of the discharging roller. At the discharging roller side of the shaft is provided a small-diameter portion, with the outer diameter of the small-diameter portion smaller than the outer diameter of another portion. A projection projects from a portion of the apparatus main body portion, a tip end of the projection being disposed in a step between the small-diameter portion and the other portion of the shaft. Also disclosed is an image forming apparatus having the sheet discharging apparatus, in which an image is formed on a sheet, and the sheet on which the image is formed is discharged by the sheet discharging apparatus.Type: GrantFiled: June 5, 2006Date of Patent: December 9, 2008Assignee: Fuji Xerox Co., Ltd.Inventors: Yasuki Tanaka, Keiji Sanekata

Patent number: 7451979Abstract: An improved sheet accumulator for stacking serially fed sheets transported on a paper path. The accumulator includes a guide deck. Above the guide deck, a plurality of parallel belts are positioned to provide a driving force for sheets on the deck. Within the accumulator, a ramp apparatus is positioned across the paper path whereby sheets driven by the belts on an upstream portion of the accumulator deck are driven over the ramp apparatus and deposited in an accumulating region of the accumulator deck on a downstream side of the ramp apparatus. Preferably, snap-down belts are provided between ramp structures snap transported sheets quickly into place on the stack and to hold them there. Sheets are stopped by an accumulator stop mechanism located at a downstream end of the accumulating region that prevents movement of sheets by the belts while sheets for an accumulation are being collected.Type: GrantFiled: September 22, 2006Date of Patent: November 18, 2008Assignee: Pitney Bowes Inc.Inventors: John R. Masotta, William J. Wright, Robert E. Manna, Charles C Fuller, John W. Sussmeier

Patent number: 7429038Abstract: A finisher for an image forming apparatus includes a pair of rotatable downstream rollers and a pair of rotatable upstream roller between which a path on which an imaged medium travels. The finisher determines when a trailing edge of the medium is about to leave a nip of the upstream rollers and then stops a leading edge of the medium. By stopping the leading edge of the medium, the medium buckles and the trailing edge registers against the upstream nip line. A finishing device performs a hole punch, staple, or other finishing operation to the medium when the trailing edge registers against the upstream nip line. The finishing operation is performed at a speed equal to or greater than a speed at which the image forming apparatus forms the image on the medium and outputs the medium to the finisher.Type: GrantFiled: July 17, 2006Date of Patent: September 30, 2008Assignee: Xerox CorporationInventors: Raymond Matthew Ruthenberg, Joseph Andre Michel Loiselle, Robert Hugh Brown
