Patent number: 4515357Abstract: A friction retard feeder adapted to feed sheets from a stack into a paper path located in a horizontal plane includes a tray which holds a stack of sheets at an angle of between 15.degree. and 20.degree. with respect to the paper path. A paddle wheel having a plurality of blades is positioned a predetermined distance in front of sheets stacked in the tray so that as the paddle wheel is rotated the blades in a first position strike the top sheet in the stack in a plane parallel to the top of the stack and separates it from the remaining sheets in the stack. Continued rotation of the paddle wheel causes the blades to deflect downward in front of the stack and thereby inhibit movement of sheets other than the top sheet from the stack. The tray also includes a high friction surfaced pad that cooperates with the paddle wheel in order to enhance the feeding of sheets near the bottom of the tray.Type: GrantFiled: December 3, 1982Date of Patent: May 7, 1985Assignee: Xerox CorporationInventor: Thomas J.

Patent number: 4264187Abstract: An electrophotographic copier has an extended transport path, including a storage for duplex functions, for copying documents which may be reproduced, to a selectable number of copies, from a master. The master is positioned first at an imaging station, so that the desired number of image transfers to copies can be made. The master document transport system recirculates the imaged master, holding it at a storage station spaced apart from the image station, while a second master is positioned at the image station. The system need not be delayed by requiring that all of the copy documents reach an exit position before the second master is inserted. Moreover if a jam occurs in any of a number of modes of operation the system is able to recall one or two masters as needed to complete the run in most expeditious fashion.Type: GrantFiled: May 14, 1979Date of Patent: April 28, 1981Assignee: International Business Machines CorporationInventor: John H. Rhodes, Jr

Patent number: 4256298Abstract: A self-compensating registration mechanism for use with a sheet feeding apparatus for advancing sheets seriatim in a travel path subject to variation in dimension transverse to the direction of sheet travel in the path. The blocking means is movable relative to the path to a first position where it is engageable by an advanced sheet for registering such sheet, and a second position removed from the path so that the sheet can be advanced past the blocking means. The blocking means is urged toward its first position and movable to its second position against such urging by means including a coupling which compensates for variation in the dimension of the travel path so that the blocking means is movable to each of its positions for any dimension of the travel path.Type: GrantFiled: January 8, 1979Date of Patent: March 17, 1981Assignee: Eastman Kodak CompanyInventor: Douglas K. Ahern

Patent number: 4247095Abstract: A sheet feeding and registering apparatus includes a document platen, a single wide document transport belt and a sheet registration member. The sheet registration member is a linear member with a plurality of lower registration edges at a first level above the platen and a plurality of sheet stripping portions raised to a level above the first level and forming therewith a series of undulations. The raised sheet stripping portions are inclined to a direction opposite the direction of sheet transport and with the document platen form a small sheet corner capturing cavity. When feeding a slightly skewed sheet to the registration edge the lead corner is first stripped from the transport belt, then physically captured by the cavity and pivoted about its lead edge until it is fully registered against the registration member.Type: GrantFiled: December 21, 1979Date of Patent: January 27, 1981Assignee: Xerox CorporationInventor: Joseph N. May

Patent number: 4243316Abstract: A registration mechanism registers document sheets on a copier platen at an edge of the platen surface. The mechanism includes a unique gate member that moves relative to the platen edge to either register a document sheet or to permit the sheet to be driven past the edge and over a sheet deflector. For duplex copying, the deflector can be raised to guide the leading edge of the sheet over the platen edge as the sheet is returned to the platen for copying a second side of the sheet.Type: GrantFiled: July 25, 1979Date of Patent: January 6, 1981Assignee: Eastman Kodak CompanyInventor: Gary B.

Patent number: 4235431Abstract: A method and apparatus is disclosed for receiving and processing a stack of small documents, such as checks. The documents are stacked in front surface-to-back surface relationship and are singly fed from the stack automatically into a path. The advancement of every two documents is interrupted for a period of time at predetermined positions along the path to effect a selected spacing between the two documents and to align their leading edges. Subsequently, the interruption of the movement of the two documents is terminated to allow the documents to continue forward in a pair at the selected spaced apart distance. The apparatus for effecting this method comprises a document feeder apparatus, a conveyor apparatus defining the document path, and a pair of rotatable gate members which rotate into and out of the path for interrupting the advancement of the documents.Type: GrantFiled: December 4, 1978Date of Patent: November 25, 1980Assignee: AES Technology Systems, Inc.Inventors: Martin T. Abrams, John R. Sargis, Paul H. Seger, Albert Beitner, Clifton C. Bishop

Patent number: 4213603Abstract: A method and apparatus for locating sheets moving in a path at a registration position in the path. The sheets, moving seriatim in a path established by a guide and a platen of a reproduction apparatus, are pinched against the platen to decelerate the sheets as they approach the registration position for copying. The pinching action is accomplished by deflecting a resilient member into the path into juxtaposition with the platen. The member covers an opening in the guide and is deflected by a mechanism extensible through the opening. In its deflected position, the member exerts a deceleration force on the sheet to retard the sheet as it approaches the registration position. The deceleration force has a component that is substantially parallel to the surface of the sheet and a component that is substantially normal to the surface and of greater magnitude than the parallel component.Type: GrantFiled: June 15, 1978Date of Patent: July 22, 1980Assignee: Eastman Kodak CompanyInventors: Robert M. Peffer, Charles H. Braun

Patent number: 4211399Abstract: Multiple size plate registration system having a platen with a top planar surface. Channels are formed in the platen and open through the top planar surface. Parallel grooves are formed in the platen spaced transversely of the platen, extending longitudinally of the platen and opening through the top planar surface. Endless belts travel in the grooves and are used for advancing a plate onto the planar surface of the platen. First and second stop pins are mounted in the platen and are extendable above the top planar surface. Controls are provided for causing the stop pins to be selectably movable between retracted positions below the top planar surface and extended positions above the top planar surface. A guide is carried by the top surface of the platen and extends longitudinally of the platen on one side of the planar surface.Type: GrantFiled: June 9, 1978Date of Patent: July 8, 1980Assignee: Eocom CorporationInventor: Norman L.

Patent number: T102003Abstract: The method and apparatus aligns the leading edge of pliable sheet material such as paper, transverse to its intended direction of travel. Feed means positively advances the material between guide members towards an alignment member pivotally mounted but releasably secured by a latch means in the plane of the desired leading edge orientation for the sheet material. Position sensing means adjacent the alignment member senses proper leading edge orientation. The latch means responds to the position sensing means operation to release the alignment member and sheet material for movement towards transport means adapted to positively engage the sheet material leading edge to convey the properly orientated sheet material.In a typical configuration, the feed means is a set of feed rollers, the alignment member is a pivotally mounted mechanical gate assembly, and the leading edge alignment sensing means is a mechanical trigger member or photoelectric sensing means.Type: GrantFiled: March 26, 1981Date of Patent: July 6, 1982Inventor: Michael K.
