Patent number: 8276743Abstract: A method and an apparatus enable the reversal of direction in a transport of articles, in particular flat mail items. The length of the leading article is measured. The two articles are transported, with a gap between them, to a direction reversal device. The direction reversal device possesses a “head station” and transports the two articles over a transport path in a transport direction and, subsequently, over the same transport path in the opposite transport direction. If the measured length is greater than a stipulated standard maximum length, the leading article is additionally transported over an additional transport route which follows the transport path, specifically, first, in the transport direction and, subsequently, in the opposite transport direction. The two articles are subsequently transported away in succession.Type: GrantFiled: March 7, 2011Date of Patent: October 2, 2012Assignee: Siemens AktiengesellschaftInventor: Armin Zimmermann

Patent number: 8249494Abstract: An image forming apparatus capable of properly discharging a medium has a first medium stacking unit, a second medium stacking unit, and a guiding member for guiding the medium to the second medium stacking unit in a case that the second medium stacking unit is set in an opened state and guiding the medium to the first medium stacking unit in a case that the second medium stacking unit is set in a closed state. Since the guiding member guides the medium to the second medium stacking unit in a case that the second medium stacking unit is set in the opened state and guides medium to the first medium stacking unit in a case that the second medium stacking unit is set in the closed state, the medium can be discharged to the second medium stacking unit in a case that large normal curling occurs.Type: GrantFiled: July 27, 2006Date of Patent: August 21, 2012Assignee: Oki Data CorporationInventor: Takemasa Ishikuro

Patent number: 8235385Abstract: An image forming apparatus and a method of controlling the image forming apparatus are provided. When a finisher is installed onto the image forming apparatus and a communication failure between the finisher and the image forming apparatus is detected, the image forming apparatus causes both of a post processing operation and a double-sided printing operation to be unavailable for selection by a user.Type: GrantFiled: July 16, 2009Date of Patent: August 7, 2012Assignee: Ricoh Company, LimitedInventor: Kiichirou Shimizu

Patent number: 8235614Abstract: An image forming apparatus including an image forming portion that forms an image on a surface of a sheet, a feeding device that feeds the sheet in a sheet feeding direction, a sheet receiving portion, and an engagement portion selectively moves between a first position and a second position. When the engagement portion is in the first position, the engagement portion engages the leading end of the sheet. When the engagement portion is in the second position, the engagement portion does not engage the sheet. When the engagement portion is in the first position, the engagement portion engages a leading end of the sheet before a trailing end of the sheet passes the feeding device. The sheet receiving portion receives the sheet after the engagement portion engages the leading end of the sheet.Type: GrantFiled: March 27, 2009Date of Patent: August 7, 2012Assignee: Brother Kogyo Kabushiki KaishaInventors: Masayuki Takata, Yoshikazu Takahashi, Kazama Goto, Naoya Okazaki

Patent number: 8210526Abstract: A device for horizontally rotating flat articles supplied along a transport line (L) has a sliding plane (2) for restively receiving articles (F) in transit between the upstream and downstream branches (RM, RV). Two drawing groups are flanked and activated independently, each constituted by a lower roller (13, 14) and an upper roller (23, 24) rotating in an opposite direction, the rollers adheringly engaging with upper and lower surfaces of the flat articles (F). Command organs (10) activate the first and second drawing groups (3, 4), first in a same direction in phase relation with an entry of a flat article (F) arriving from the upstream branch (RM) and then in opposite directions in order to horizontally rotate the flat article (F) by a predetermined angle, and once more in a same direction for directing the rotated flat article (F) towards the downstream branch (RV) of the transport line (L), in a direction parallel to the entry direction.Type: GrantFiled: September 9, 2009Date of Patent: July 3, 2012Assignee: C.M.C. S.r.l.Inventor: Francesco Ponti

Patent number: 8208847Abstract: A sheet folding apparatus includes a fan folding unit that fan folds a folded-back sheet into a width or length of the regular size to file the sheet in the regular-size folder such that the sheet forms layers along a traveling direction of the sheet; first and second punching units that punch the filing hole in the sheet fan folded, respectively, into the width and the length of the regular size at the portion to be punched to file the sheet in the regular-size folder; and a sheet-processing setting unit that sets a fold mode of the fan fold and selects one of the first punching unit and the second punching unit for use in punching of the filing hole in the sheet based on a size and orientation of the delivered sheet.Type: GrantFiled: November 2, 2007Date of Patent: June 26, 2012Assignee: Ricoh Company, Ltd.Inventor: Yusuke Harasawa

Patent number: 8200139Abstract: A method and apparatus for efficiently scanning a duplex document in which a scan unit sequentially scans both sides of a sheet of a duplex document by moving the sheet across a reader, and a reverse output unit to output the sheet after turning over the sheet. Therefore, since the sheet of a document can be fed and scanned while the second side of the previous sheet of the document is scanned, scanning time can be reduced. Particularly, the reduction in scanning time is very useful when multiple sheets of a duplex document need to be scanned.Type: GrantFiled: October 11, 2007Date of Patent: June 12, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Sang-cheol Park, Yong-kon Jo

Patent number: 8172228Abstract: An integrated module for installation within a printer may include a module frame and a plurality of printer subsystem components. The module frame is configured to fit within a predetermined space within a printer and to connect to a printer frame positioned about the predetermined space. The plurality of printer subsystem components are configured to mount to the module frame. At least one printer subsystem component includes a default module media path and at least one diverter-directed module media path within the printer subsystem component. The at least one printer subsystem component is configured to connect to the module frame at a position that enables the default module media path and the at least one diverter-directed module media path to complete a printer media path through the predetermined space when the module frame having the printer subsystem component is connected to the printer frame.Type: GrantFiled: March 26, 2009Date of Patent: May 8, 2012Assignee: Xerox CorporationInventors: Rob Huala, Jos Jacobs, David B.

Patent number: 8172225Abstract: A feeding device has a conveying roller that rotates in a forward direction and a reverse direction, to selectively convey a sheet in a conveying direction and a reverse conveying direction. A particular guide member is positioned on an upstream side, guides the conveyed sheet toward the conveying roller, and has a stopper that contacts an end portion of the sheet, thereby stopping movement of the sheet in the reverse conveying direction. A control unit causes the conveying roller to rotate the conveying roller in the forward direction, such that the sheet is conveyed to a predetermined position, then to rotate the conveying roller in the reverse direction, wherein the end portion of the sheet contacts the stopper while the conveying roller rotates in the reverse direction, and then to again rotate the conveying roller in the forward direction, such that the sheet is conveyed toward the conveying roller.Type: GrantFiled: March 5, 2010Date of Patent: May 8, 2012Assignee: Brother Kogyo Kabushiki KaishaInventor: Naokazu Tanahashi
