Patent number: 4500086Abstract: A rotating inverter mechanism includes a drive shaft and dual primary and secondary rollers mounted within a set of collars such that the drive shaft is adapted to provide rotation to the primary rollers in a clockwise direction while the secondary rollers which are initially in an out of sheet contact position are driven by the primary rollers in a counterclockwise direction. A sheet passing through the inverter in a clockwise direction actuates a first sensor which in turn actuates a solenoid linked to one of the collars. The solenoid pulls the collar through a predetermined angle and thereby places the corresponding secondary roller in contact with the sheet. Since the secondary roller is rotating in a direction opposite to the incoming sheet direction and opposite to the other primary roller, the sheet will be rotated. A chute is positioned to deflect the sheet downward as it is rotated so that the rotation can be accomplished in a distance no wider than the width of the sheet.Type: GrantFiled: December 1, 1982Date of Patent: February 19, 1985Assignee: Xerox CorporationInventor: Gerald M.

Patent number: RE32284Abstract: A system for presenting documents to a slit-scan xerographic exposure station includes a fluidic storage station having a housing in which a rack for storing documents is located. The rack includes a plurality of pockets in each of which a document may be stored, the rack being movable in a vertical direction so that any one of its pockets may be aligned with an opening in the housing. A fluid stream is used to move a document in a pocket aligned with the opening out of the storage apparatus and into engagement with transport apparatus. The transport apparatus includes a vacuum document drum which moves a document past the exposure station and, in one mode of operation, inverts the document prior to its return to a pocket at the station. In another mode of operation, the direction of travel of the drum is reversed after the document has been exposed and the document is returned without inversion.Type: GrantFiled: July 2, 1979Date of Patent: November 11, 1986Assignee: Xerox CorporationInventors: Klaus K. Stange, Richard E. Smith, Thomas J. Hamlin, James R. Cassano

Patent number: RE32541Abstract: A system wherein documents are presented to an exposure station of reproduction apparatus includes a housing in which a rack for storing documents is located. The rack includes a plurality of pockets in each of which a document may be stored, the rack being movable in a vertical direction so that any one of its pockets may be aligned with an opening in the housing. Fluid streams are used to either move a document in an aligned pocket through the opening and to the exposure station or from the exposure station into the pocket. Copies of documents presented to the exposure station are made by the reproduction apparatus. Adjacent the housing there is located an inverter into which documents from the rack are fluidically fed as desired. Inverted documents are returned to the rack with the assistance of a fluid stream. Inverted documents may be fed to the exposure station to provide duplex copies.Type: GrantFiled: July 7, 1981Date of Patent: November 10, 1987Assignee: Xerox CorporationInventors: Klaus K.
