  • Thermal printer with means for reducing color shifts
    Patent number: 5526033
    Abstract: A thermal printer includes a memory for storing a correction for cancelling variations in a paper feed caused by a previously determined uneven paper feed, a first calculator for calculating an uneven paper feed in each of the lines to be printed, a second calculator for calculating a correction corresponding to the uneven paper feed calculated by the first calculator; and a control for controlling the paper feed in each of the lines according to the correction calculated by the second calculator.
    Type: Grant
    Filed: May 5, 1995
    Date of Patent: June 11, 1996
    Assignee: Mitsubishi Denki Kabushiki Kaisha
    Inventors: Kazuhiko Higashi, Kiyoshi Takakuwa, Kazuaki Arimoto, Kenichi Naruki, Hiroshi Fukumoto, Terumi Kuwada, Keisuke Oda

  • Color printer capable of utilizing a jointed color ink sheet
    Patent number: 5424762
    Abstract: The provision is made of a firmware (F/W: ROM, RAM) which enables an accurate indexing of an ink sheet so that printing is not performed at the joint portion when an ink sheet having a joint is used. Therefore, an ink sheet having a joint can be used, decreasing running cost of the printer.

  • Video signal brancher
    Patent number: 5287450
    Abstract: A video signal brancher is provided which facilitates printing of image data of video signals having dissimilar parameters. Image data is branched and sent to data output terminals. Synchronizing data signals are branched and sent to synchronizing signal output terminals. Parameters consisting of image data and synchronizing signals are stored and image data is printed based on the stored parameters.

  • Printer with dual color density regulation
    Patent number: 5189440
    Abstract: A printer for printing variable density, multiple color prints in response to commands for controlling parameters, such as color density of a printed image, and image data sent from a host computer includes a CPU responsive to commands from the host computer; a first variable density regulating circuit storing color density correction data, receiving image data from the host computer, and connected to and controlled by the CPU for totally regulating the color density of a color image to be printed and outputting totally regulated image data; a second variable density regulating circuit connected to the first variable density regulating circuit and to the CPU and storing a plurality of predetermined density regulating data for finely regulating the color density of the color image to be printed in response to the totally regulated image data received from the first variable density regulating circuit and one of the predetermined density regulating data selected by an operator through the CPU and outputting fin
