Patent number: 4972208Abstract: Image frame length control apparatus and methods are disclosed which have particular utility in a printing or reproduction apparatus that writes one or more images on a transported photosensitive media such as a photoconducting drum or continuous-loop web. When an electronic writing system or optical exposure system is used to expose a driven media on a line-by-line basis, a variation in media thickness causes the latent image frame to be written with an inaccurate frame length. Consequently, a degraded print is produced.The latent image frame length is corrected during exposure, by adding or omitting one or more lines in the image frame. Alternatively, the exposure of an image is offet by an interval corresponding to one-half of the total length discrepancy between the uncorrected image frame length and the image frame length that would be written if the media surface speed was at a median level.Type: GrantFiled: August 28, 1989Date of Patent: November 20, 1990Assignee: Eastman Kodak CompanyInventors: Timothy Young, David J.

Patent number: 4843338Abstract: Several problems of alignment associated with ink-jet printers are alleviated by four aspects. In the first, a reverse bow (B) in the paper (12) is created for printing on single sheets of paper. The reverse bow, which in the transverse axis of the paper, forces the paper flat against the platen (14) by using the paper's own stiffness.In the second aspect, the paper and the carriage (30) are referenced to the same part (the carriage guide (10)). In this configuration, the paper is urged against the underside of the carriage guide off of drive rollers (18), through the reverse bow, and onto the platen, where it is printed. The carriage is referenced to the carriage guide through a slider bump by means of a carriage shaft and gravity.The carraige guide comprises stiff thin sheet metal, which is closely-toleranced and has well-controlled dimensions. Thus, this part is good to reference to, rather than molded-in parts, which are not stiff enough at the required thickness.Type: GrantFiled: October 23, 1987Date of Patent: June 27, 1989Assignee: Hewlett-Packard CompanyInventors: Steve O.

Patent number: 4833487Abstract: An image is recorded on an elongate image recording medium by feeding the image recording medium in an auxiliary scanning direction from a loading unit and applying a light beam to the image recording medium in a main scanning direction transverse to the auxiliary scanning direction. A loose loop is formed out of the image recording medium between the loading unit and an image scanning recording unit. Guide plates are angularly displaced to allow the image recording medium to hang by gravity with the image recording medium with the image recorded thereon having a free distal end. The hanging image recording medium is moved back toward the image scanning recording unit after the image has been recorded. The guide plates are displaced back to deliver the image recording medium to a next process.Type: GrantFiled: December 3, 1987Date of Patent: May 23, 1989Assignee: Fuji Photo Film Co., Ltd.Inventors: Yoshihiro Koyanagi, Takashi Imamura, Gen Sasaki

Patent number: 4827292Abstract: A system includes a work table having a flat surface which supports a first and a second sheet material during a work operation and has a carriage carrying an instrument to enable it to perform work operations on the first and second sheet materials. The first material is advanced by a first material advancing means that moves the first sheet material in a first flow direction which is coincident with the direction of movement of the carriage. A second material advancing means moves the second sheet material over the support surface and underneath the first sheet material. Guide means are oriented at each opposite end of the table to permit indexing of the sheet materials across the table. The guide means which position the second material on the surface of the work table are skewed at an angle relative to a coordinate direction which is orthogonal to the direction of movement of the carriage.Type: GrantFiled: June 3, 1988Date of Patent: May 2, 1989Assignee: Gerber Garment Technology, Inc.Inventor: Richard Kuchta

Patent number: 4791433Abstract: In a line scan fiber optic cathode ray graphic recorder a continuous sheet of light sensitive paper is drawn perpendicularly before a regularly timed intensity modulated beam from the cathode ray tube. Due to gearing inaccuracies and anomalies, the velocity at which the paper is drawn past the beam varies cyclically resulting in a variation in the spacing between each recorded data line on the paper. For higher paper velocities, the recorded lines are closer together, and for lower paper velocities, the recorded lines are farther apart. The closer lines create a darker image band on the paper and the more distant lines create a lighter image band on the paper. The present invention includes paper velocity monitoring means which provides an input signal to a compensation circuit for inversely varying the intensity information of each pixel dot as a function of the paper velocity.Type: GrantFiled: February 2, 1983Date of Patent: December 13, 1988Assignee: Tektronix, Inc.Inventor: Samuel W.
