Patent number: 7487965Abstract: An apparatus for fabricating a multi-sheet mailpiece including a compiler, and axial and radial deformation binding mechanisms. The compiler includes a sheet feeding apparatus and registration device for accepting multiple individual sheets. The sheet feeding apparatus lays the sheets onto a compiler tray to form a multi-sheet stack having face sheets and content sheets disposed therebetween. The registration device includes first and second registration gates for aligning the edges of the sheets, such that at least one edge of the content sheets is disposed inboard of the face sheets to define a peripheral edge. A controller positions the first and second registration gates from a registration position to a release position as the sheet material is laid upon the compiler tray. Finally, the multi-sheet stack is fed to the axial and radial deformation binding mechanisms to secure the peripheral edge of the multi-sheet stack to form mailpiece enclosure.Type: GrantFiled: July 22, 2005Date of Patent: February 10, 2009Assignee: Pitney Bowes Inc.Inventor: Denis J.

Patent number: 7481427Abstract: An automatic document feeder of the present invention is provided with a turning/discharging path in a reversing path in order to read images on both sides of documents in lengths less than the main size and discharge in a discharging tray. Further, an aligning wall is provided to bump ends of documents discharged from the turning/discharging path against it. Thus, the documents of which both sides are read are discharged in the sequentially collated state at a high-speed and the aligned state.Type: GrantFiled: March 9, 2005Date of Patent: January 27, 2009Assignees: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventor: Akihito Tokutsu

Patent number: 7475874Abstract: When a new paper sheet is supplied onto a compiling tray, a sub-paddle holds down paper sheets having already been stacked on the compiling tray until a leading edge of the new paper sheet S touches the stacked paper sheets. Thereafter, the sub-paddle gets apart from the sheets stacked on the compiling tray with timing, with which the rear edge of the new paper sheet falls on the compiling tray.Type: GrantFiled: October 11, 2006Date of Patent: January 13, 2009Assignee: Fuji Xerox Co., LtdInventor: Ryuichi Sato

Publication number: 20080185773Abstract: A sheet processing apparatus of the invention includes a post-processing unit that applies post-processing to sheets supplied from an image forming apparatus, a conveying tool that guides the sheets subjected to the post-processing to a discharge port, a sheet discharge tray that receives the sheets discharged from the discharge port, and a control unit that controls an operation of the conveying tool and stops a discharge operation for new sheets, when a quantity of the sheets stacked on the sheet discharge tray reaches a full state set in advance. The sheet processing apparatus further includes a pressing unit that temporarily prevents movement of the sheet on the conveying tool, when a sheet is present on the conveying tool in the full state.Type: ApplicationFiled: February 1, 2007Publication date: August 7, 2008Applicant: TOSHIBA TEC KABUSHIKI KAISHAInventor: Mikio Yamamoto

Patent number: 7370861Abstract: A detection sensor detects a position of a level detection lever that touches an uppermost sheet of sheets stacked on a holding tray, and a computing device counts the number of sheets that have been discharged to the holding tray. A judging device judges the amount of sheets stacked based on a sheet surface level detection signal from the detection sensor and a count value of the computing device. The apparatus accurately judges that the maximum amount of sheets have been stacked in the holding tray according to the position of the level detection lever and a count value for a number of sheets. Also, the apparatus selects one of a plurality of values for an offset sheet count, which corresponds to the operating conditions, namely the transporting speed of sheets, the intervals between sheets, and the length of the transport direction of the sheets.Type: GrantFiled: February 24, 2005Date of Patent: May 13, 2008Assignee: Nisca CorporationInventors: Tatsuzo Aoyagi, Tatsuya Niwa, Yoshihiko Minagawa

Patent number: 7333224Abstract: The present invention provides a system and method for managing printed documents. The method includes receiving a print request, assigning an identifier to a print job associated with the print request, and sending the print job to a printer for printing. Once the printer completes printing the print job, the identifier is added to an unretrieved print job queue. When a printed document associated with the print job is retrieved, the identifier associated with the printed document is scanned, such as with a bar code reader. Once the identifier is scanned, a retrieval confirmation is sent to indicate that the printed document has been retrieved. The identifier is then removed from the unretrieved print queue. Notification messages are sent to a notification recipient while the identifier is in the unretrieved print queue. The notification message includes an email message, a pop-up window, a pager message, and the like.Type: GrantFiled: June 5, 2002Date of Patent: February 19, 2008Assignee: Microsoft CorporationInventor: Michael D.
