Publication number: 20030222389Abstract: An apparatus for processing, stacking and thereafter collecting printed forms, includes: a dual registering stacking interface, that stacks and accumulates forms in a stack or in a continuing feeding as separate forms; and, a sequencer merger that receives the forms from the dual registering stacking interface and directs the forms in a selected order to an output end. The output end communicates with an accumulator that feeds the forms to a folder. The folder thereafter feeds the forms to a collector to be held until called for by a subsequent downstream device, such as a mail inserter device. The resister, accumulator and collector are belt and/or roller driven devices, wherein the invention provides clutching assemblies for the transport belts and rollers in order to eliminate the streaking of the printed forms when idled forms are held stationary against the transport belts.Type: ApplicationFiled: February 6, 2003Publication date: December 4, 2003Inventors: Kenneth A. Stevens, Douglas A. Keller

Patent number: 6568676Abstract: A turnbar for use in a sheet accumulator having an accumulating assembly which causes sheets serially and separately entering an entry point to overlap each other to form a stack at an exit point. The turnbar is used to change the direction of the sheets at the entry point and the stack at the exit point. The turnbar can be disengaged from the accumulating assembly for jam clearance and maintenance purposes. Preferably, the turnbar has a securing mechanism for removably mounting the turnbar on the sheet accumulator.Type: GrantFiled: October 17, 2001Date of Patent: May 27, 2003Assignee: Pitney Bowes Inc.Inventors: Robert E.

Patent number: 6352253Abstract: A discharged sheet stacking apparatus includes a sheet feed-in device for pinching and feeding a sheet onto a sheet stacking portion on which a plurality of sheets are stacked and for causing a tip end of the sheet to abut against a sheet stopper. The sheet feed in device is disposed at a position spaced apart from the sheet stopper by a distance smaller than a length of the sheet. The sheet feed-in device continues the feeding operation while pinching a tail end of the sheet even after the tip end of the sheet abuts against the sheet stopper so that, after a loop is formed in the tail end of the sheet, the sheet is discharged onto the sheet stacking portion.Type: GrantFiled: February 17, 1999Date of Patent: March 5, 2002Assignee: Canon Kabushiki KaishaInventors: Yasuyoshi Hayakawa, Teruo Komatsu, Tsuyoshi Waragai, Atsushi Ogata

Patent number: 6332606Abstract: A finisher system for an image formed sheet transported from an image forming apparatus. A finisher finishes the image formed sheet. A direct sheet feeding path feeds the image formed sheet to a sheet stacker. The sheet finishing path is branched from the direct sheet path for transporting the image forming sheet to the sheet stacker by way of the finisher, and the sheet finishing path can include a turning point. A sheet piling system set in the sheet finishing path piles up the image formed sheets. Further, a stopper is set in the finishing path for temporarily trapping the image formed sheets. The sheet piling system can include plural sheet suspending paths which each suspend a transported sheet and which each include a sheet transport device, and such that the stopper is set between the turning point and the sheet transport devices. The direct sheet feeding path can also be straight and the stopper may be configured to be positioned into and out of the sheet finishing path.Type: GrantFiled: September 29, 2000Date of Patent: December 25, 2001Assignee: Ricoh Company, Ltd.Inventor: Nobuyoshi Seki

Patent number: 6325368Abstract: A sheet output device having a stack for storing sheets and a plurality of discharge bins includes a sheet transport device for transporting a discharged sheet from a discharge bin to the stack and an indicator for indicating that the sheet has been transported by the sheet transport device, so that the user can know where the job sheet is to be output. The sheet output device further includes a memory for storing information related to a sheet output for each of the discharge bins, and the indicator indicates information related to the sheet transported by the sheet transport device.Type: GrantFiled: October 8, 1999Date of Patent: December 4, 2001Assignee: Minolta Co., Ltd.Inventors: Hiroaki Ikeda, Akinori Yoshida, Motomi Takemoto

Patent number: 6273413Abstract: An automated banking machine (10) includes a user interface (12) including an opening (20) for users to deliver and receive individual sheets and stacks of sheets to and from the machine. The machine includes a sheet handling mechanism therein including a first transport path (46) and a second transport path (42). Various devices for dispensing and receiving sheets (30, 32, 34, 36, 38, 40) are positioned adjacent to the second transport path and dispense and/or receive sheets therefrom. The second transport path meets the first transport path at an intersection (60). The machine includes control circuitry (44) which controls the dispensing and movement of sheets along the sheet paths in response to inputs by customers. A sheet directing apparatus (110) is positioned adjacent to the intersection (60). The sheet directing apparatus (110) is selectively operative as a stack of sheets moves through the intersection to either add a sheet to the stack or to separate a sheet from the stack.Type: GrantFiled: November 28, 1997Date of Patent: August 14, 2001Assignee: Diebold, IncorporatedInventor: H.

Patent number: 6273419Abstract: A method and device for collating a number of sheets, serially and separately entering an entry point, into a stack at an exiting point without slowing down or pausing the sheets. The method and device, according to the present invention, provide a plurality of traveling paths with different path lengths to connect the entry point and exiting point, and use controlling devices to control the paths such that a sheet entering the entry point will travel a shorter path than the preceding sheet. It is preferred that the path length difference between any two adjacent paths is the same. The path length difference can be smaller than or equal to the length of the sheets. When the path length difference is equal to the sheet length, all sheets travel through different paths will arrive the exiting point concurrently.Type: GrantFiled: May 12, 1999Date of Patent: August 14, 2001Assignee: Pitney Bowes Inc.Inventors: Robert J. Allen, John W. Sussmeier, William J. Wright
