Patent number: 4949129Abstract: A transfer member, for example, a transfer drum utilizes a vacuum applied through vacuum holes to the drum surface for holding a receiving sheet. A toner image is transferred to the sheet under the urging of an electric field. To prevent non-transfer over the vacuum holes, the holes are filled or covered with a conductive material that is sufficiently conductive to maintain the electric field over the holes and sufficiently porous to maintain the vacuum at the surface. For example, a polyurethane foam material can be used for the material in or over the vacuum holes.Type: GrantFiled: July 3, 1989Date of Patent: August 14, 1990Assignee: Eastman Kodak CompanyInventors: William Y. Fowlkes, Bruce J. Rubin, Victor C. Solomon, William B. Vreeland

Patent number: 4947450Abstract: Apparatus for reading optically a scene made up of symbols on a transparent medium comprises a transparent flat plate on which the scene is supported. An illumination system on one side of this plate illuminates at least part of the scene. An optical reader device on the opposite side of the plate incorporates an optical sensor. A pneumatic skid is moved over the opposite side of the plate and has a recess in its surface facing the plate in which the sensor is accommodated. Thus the scene is scanned by the sensor as the skid is moved over the plate.Type: GrantFiled: September 8, 1987Date of Patent: August 7, 1990Assignee: UP SystemsInventors: Jean-Marie Billiotte, Thierry Bouin, Frederic Basset, Jacques Beauvois, Didier Primat

Patent number: 4931826Abstract: An apparatus 10 for printing and processing photographs is disclosed. The printer-processor has a printing unit 11 and a processing unit 12. A light source 18 directs light 64 toward light-sensitive photographic printing material 22. The negative 19 is held by a rotatable negative carrier 20. The optics 21 for the printer-processor 10 are mounted upon a rotatable lens carousel assembly 63 having a plurality of lens decks 65. The printing material 22 is supported by one or two platens 23, 96, each having a plurality of vacuum grooves 174 to hold the print material 22. A transport system 132 conveys the print material 22 from the platen 23, 96 to the entrance 29 of the processor 12. The transport system 132 includes a pre-accumulation conveyor system 147 and a post-accumulation conveyor system 149, between which is a holding area 40 and accumulation system 148 for accumulating exposed print material 22.Type: GrantFiled: December 1, 1988Date of Patent: June 5, 1990Assignee: Castle Rock Manufacturing, Inc.Inventors: Orren J.

Patent number: 4885606Abstract: A transport belt for an automatic camera vacuum feed and hold down system is provided. The movable, flexible opaque transport belt has a substantially uniform bottom surface facing the exposure platen and a top surface provided with at least one transverse resilient belt flexing member. The belt flexing member is preferably a curved plastic member having memory which assumes a first, curved position to create at least one air channel beneath the belt. The air channels reduce the length of time required to evacuate air beneath the belt. During vacuum hold down for exposure, the resilient belt flexing member assumes a second position, substantially parallel to the platen and the air channels are eliminated, such that the bottom belt surface presents a substantially flat uniform background surface during exposure.Type: GrantFiled: June 29, 1988Date of Patent: December 5, 1989Assignee: Itek Graphix Corp.Inventor: Daniel H. Robbins

Patent number: 4881711Abstract: A variable width transparent photographic film vacuum hold-down device. Two spaced parallel vacuum slits formed on a flat platen are connected by the longitudinal edges of the film, and when covered by a flexible cover sheet form two vacuum channels holding the film flat and unobscured to the extreme edges. Any film width not exceeding the length of the vacuum slits is held without any modification or adjustment to the device. Any length of film can be used.Type: GrantFiled: March 21, 1988Date of Patent: November 21, 1989Assignee: The Perkin-Elmer CorporationInventor: Joseph F. Vollaro

Patent number: 4814832Abstract: An automatic vacuum feed and hold down system is provided having a transport belt with vacuum grippers, a peripheral vacuum channel surrounding the platen, and a lead edge blow apparatus. In the preferred embodiment the transport belt consists of polyester fabric selectively coated with plastisol sealant to define a window area similarly shaped but smaller than the platen and suction grippers within the window area. In the preferred mode of operation a lifting apparatus raises the belt away from the exposed photosensitive sheet on the platen and the natural curl of the sheet, together with the lead edge blow, cause the sheet to release from the platen. The lifting apparatus then lowers the belt and suction is reapplied to the grippers, whereafter the belt and sheet are raised and advanced to deliver the exposed photosensitive sheet for processing.Type: GrantFiled: January 28, 1988Date of Patent: March 21, 1989Assignee: Itek Graphix Corp.Inventors: Juergen Lein, Michael Brookmire, Robert Powers, Joel Hotelling

Patent number: 4791456Abstract: A photographic printer apparatus is provided, with quick change self-threading magazines of photographic material which enables use of different widths and types of photographic material at the input of the printer apparatus. A cutter station is positioned within the printer console adjacent the magazine input, where roll material is pre-cut to the desired size of the photographic print to be made before being exposed. Transport systems are provided in the console for vacuum guidance and positioning of the photographic material while it is being cut and for accurately positioning the photographic material opposite a first exposure station for exposure, and for transporting the piece of photographic material to a second exposure station or for storage and subsequent processing or to a continuously running processor adapted to develop, and wash and dry the previously exposed photographic material.Type: GrantFiled: April 15, 1987Date of Patent: December 13, 1988Inventors: Henry F.
