Patent number: 6009302Abstract: An automatic document feeder mounted removably to a computer input device having a medium receiving and supporting surface includes a plurality of interconnectable modular assemblies for defining a medium path that extends from a medium input tray to a medium output tray via the medium receiving and supporting surface of the computer input device. One of the modular assemblies is a main chassis assembly includes an integrally formed main chassis shell having a substantially planar base. The input tray extends upwardly from the base and has a document receiving surface with a concave shape in both the vertical and horizontal planes to help facilitate proper sheet stiffening and alignment for sheet loading purposes onto the receiving and supporting surface of the computer input device. A paper pick and transport mechanism is housed in the main chassis and protrudes through a set of apertures in the output tray.Type: GrantFiled: October 28, 1998Date of Patent: December 28, 1999Assignee: Hewlett-Packard CompanyInventors: A.

Patent number: 6007959Abstract: An image forming material which comprises fine resin particles and a recording component held inside the fine resin particles. The recording component comprises a colorant and water, and the fine resin particles can, when supplied with an electric energy, release the recording component held inside. The image forming material is brought into contact with a latent image holding body on which a latent image has been formed. Then an image is produced by applying an electric energy on the image forming material for the liquefaction thereof to wet and develop the latent image on the latent image holding body with the recording component contained in the image forming material.Type: GrantFiled: October 22, 1996Date of Patent: December 28, 1999Assignee: Fuji Xerox Co., Ltd.Inventors: Hirotaka Matsuoka, JongWon Lee

Patent number: 6002419Abstract: The present invention is for an imaging processing apparatus (10) for thermal print medium. The image processor apparatus (10) comprises a vacuum imaging drum (300) for holding thermal print media(32) and donor sheets (36) in registration on the vacuum imaging drum (300). A printhead (500) moves along a line parallel to a longitudinal axis X of the imaging drum (300) as the imaging drum (300) rotates. The printhead (500) receives information signals and produces radiation which is directed to the donor (36) which causes color to transfer from the donor (36) to the thermal print media (32). At least part of a surface of the vacuum imaging drum (300) has micropaths over at least a portion of a surface of the vacuum imaging drum (300). In one embodiment the micropaths are produced by sandblasting (330). At least one vacuum hole or slot is located on the surface of the vacuum imaging drum (300), connecting to the micropaths.Type: GrantFiled: January 21, 1997Date of Patent: December 14, 1999Assignee: Eastman Kodak CompanyInventors: Roger S. Kerr, Dean L. Smith, Douglas A. Hons

Patent number: 5982410Abstract: An improved method and apparatus to record picture information on recording material in the form of single sheets. The picture information to be recorded for each sheet is present in electronically stored pixel form and is recorded pixel by pixel onto the recording material. The sheets of the recording material are transported through a paper stage of a printer in at least two adjacent tracks, and the stored picture information belonging to the respective sheets located in the recording station is recorded onto the sheets located in the adjacent tracks. Because the sheets are transported in a plurality of tracks through the recording station, a higher throughput can be attained even if smaller sheet sizes are being processed.Type: GrantFiled: April 3, 1998Date of Patent: November 9, 1999Assignee: Gretag Imaging AgInventor: Beat Frick

Patent number: 5973715Abstract: Image processing equipment (10) having an image processor housing (20) and a transport roller assemblage (100) for transporting a web (116) of donor dye material (44) arranged in the housing. The transport roller assemblage (100) has at least one of either the first and second rollers (112, 114) comprising a composite mixture of polymer and inorganic particulate materials (172). Alternatively, a hard coating (182, 184) is applied on a polymeric roller comprising primarily hard inorganic particles.Type: GrantFiled: June 4, 1998Date of Patent: October 26, 1999Assignee: Eastman Kodak CompanyInventors: Syamal K. Ghosh, Edward P. Furlani, Dilip K. Chatterjee

Patent number: 5973721Abstract: A method of printing image information on a receiving material, two sides of which are provided with a binding portion for collecting a plurality of receiving materials into a booklet, the image information of at least two images being printed next to one another on the receiving material such that the images situated next to one another are printed with reading orientations rotated 180.degree. relative to one another and forming a right angle with the sides of the receiving material that are provided with the binding portion. To rotate the images, a fast method of rotating digital images is described which requires minimal memory space. Furthermore, the rotation method is particularly applicable to rotating a series of images and includes the capability of rotating each image in the series differently while utilizing minimal memory space and processor time.Type: GrantFiled: March 21, 1997Date of Patent: October 26, 1999Assignee: Oce-Technologies B.V.Inventors: Jacques J. H. Bergmans, Gerardus G. J. C. Kessels, Theodrikus H. I. E. van Gasteren, Eduardus J. W. van Vliembergen, Antonius H. J. G. Lommen

Patent number: 5970597Abstract: According to a precision assembly technique, a first subassembly is precisely aligned relative to a plurality of alignment features in an alignment fixture and at least three non-coplanar flexures having complementary alignment features are located with respect to corresponding alignment features on the alignment fixture and mechanically attached to the first subassembly. The first subassembly with the attached flexure sheets is removed from the alignment fixture and located with respect to a second subassembly having a plurality of alignment features identical to the alignment features in the alignment fixture using the alignment features on the second subassembly and the complementary alignment features on the flexure sheets to precisely align the first subassembly with the complementary alignment features on the second subassembly. The flexure sheets are then mechanically attached to the second subassembly, whereby the first and second subassemblies are aligned and rigidly connected to one another.Type: GrantFiled: May 13, 1998Date of Patent: October 26, 1999Assignee: Eastman Kodak CompanyInventors: Mark D.
