  • Patent number: 6360657
    Abstract: A printer is capable of stably feeding even a thin recording medium to a printing section and obtaining good print quality similar to that obtainable in the case of a thick recording medium. The printer comprises a first supply path for supplying a first recording medium, a second supply path for supplying a second recording medium thicker than the first recording medium, a printing section for printing on a recording medium supplied from the first supply path or the second supply path, and a delivery section for delivering the recording medium printed in the printing section. A guide spring member which is movable up and down is projected upstream of the printing section and in a meeting portion of the first supply path and the second supply path. This guide spring member serves to support a top surface of the first recording medium at a predetermined height.

  • Patent number: 6341906
    Abstract: A tape cassette is set in a cassette accommodating section of a tape printer. A magnetically affixable printing tape is fed out from a holding reel along with an ink ribbon having a non-magnetic ink layer formed thereon across a cut in the tape cassette and conveyed through between a thermal head and a platen roller while being pressed by those elements. The printing tape comprises a printing layer and a magnetic layer pasted to the printing layer. The magnetic layer is magnetized such that S and N poles are alternately arranged longitudinally of the tape to thereby prevent turns of the tape roll from shifting widthwise. The magnetic layer has a coated fluorine layer formed thereon or has wrinkles formed thereon to thereby prevent blocking from occurring on a printing face of the tape due to its winding. Thus, the printing tape is conveyed in a correct attitude to enable a high quality image to be printed thereon.

  • Patent number: 6341859
    Abstract: Ink jet printing apparatus is disclosed for forming ink images on a receiver and for treating the ink images formed on the receiver in response to one or more digital image file(s) each including at least one digital image. At least one ink jet print head delivers ink to the receiver, which moves along a first receiver path past the ink jet print head. A receiver cutter is actuatable to cut the receiver across the first receiver path. The receiver is moved along a second receiver path that is perpendicular to the first receiver path and a receiver finisher provided adjacent to the second receiver path treats the ink images formed on the receiver for enhancing the durability and the stability of such ink images. Control circuitry is responsive to one or more digital image files for actuating the ink jet print head to form a plurality of ink images on the receiver, and for actuating the receiver cutter and the receiver finisher in a time sequence so as to automatically produce prints of stable ink images.

  • Patent number: 6334677
    Abstract: Ink jet printing apparatus for forming a plurality of ink images on receivers in response to one or more digital image file(s) each including at least one or more digital images and information indicating the number of ink images to be made. The ink jet printing apparatus includes at least one ink jet print head adapted to deliver ink to the receiver and at least two receiver webs. The ink jet printing apparatus selectively moves one or more receiver webs along a receiver path past the ink jet print head. A control circuitry responsive to the digital image file(s) determines the locations of the ink images to be formed on the two receiver webs in such a manner that minimizes receiver waste. The ink jet printing apparatus actuates the ink jet print head(s) to form ink images on the receiver webs, whereby receiver waste is minimized.

  • Patent number: 6330857
    Abstract: The printing machine is designed to print different polygraphic matter without replacement of the printing form upon transition from printing one publication to another. The machine includes a printing form in the form of a mesh, and operates by filling all of the mesh cells with ink and forcing the ink through selected mesh cells by the light-hydraulic effect, which is to heat part of the ink volume in a cell with a laser beam pulse which in turn ejects all of the ink from the cell toward a receiving medium.

  • Patent number: 6318854
    Abstract: Accurate advance of a media sheet is achieved by carrying the media sheet on a belt loop. An upstream pinch roller holds the media sheet to the belt upstream of the print zone. A downstream pinch roller holds the media sheet to the belt downstream of the print zone. A guide shim extends along the media path from a position upstream of the upstream pinch roller, passed the upstream pinch roller toward the print zone. The guide shim advances with the bottom edge of the media sheet into the print zone to stabilize the trailing edge so as to allow for a smaller minimum bottom margin.
