  • Patent number: 6876376
    Abstract: In a recording apparatus, a recording medium is fixed to a recording medium fixing member. To record a desired image, the recording medium is exposed to light containing image/character data, while the recording medium is moved in the main scan direction, and a plurality of spots arrayed on the recording medium are moved in a direction orthogonal to the main scan direction. In the recording apparatus, first and second exposure operations are performed. In the first exposure operation, the recording medium is exposed to the light containing image/character data, while forming pixel groups or island patterns each consisting of a predetermined number of pixels consecutively arrayed on the recording medium in the main and sub-scan directions. In a second exposure operation and the subsequent ones, the pixels in an unexposed area other than the island patterns on the recording medium are successively exposed to the light.

  • Patent number: 6873347
    Abstract: A transfer sheet separated from a support member is held and its recording position is detected, and the separated transfer sheet is returned and superposed on the recording surface of a support member which is then delivered in. Based on the result of the detection of the recording position, the returning position of the transfer sheet is changed or image data to be recorded are changed, thereby carrying out a recording operation over the support member by using an unrecorded section present between the recorded stripes of the transfer sheet. For example, the transfer sheet is returned to almost the same position as that set before the separation and the recording position is shifted at an arrangement pitch of a stripe corresponding to 1 to 1.5 pitches to carry out the recording operation. Thus, the recording operation is performed over the support member by using an unrecorded section.

  • Patent number: 6825908
    Abstract: Apparatus and method of forming a spacer for use in a liquid crystal panel are capable of economizing materials used for spacers for use in the liquid crystal panel and reducing a quantity of waste of the materials used, while being suitable for a large-scaled liquid crystal panel. A recording medium having an image forming layer is superposed on a substrate used to form a liquid crystal panel, then the recording medium is exposed through irradiation of a laser beam emitted from a recording head, and an image pattern of spacers is thereby recorded in the image forming layer. The image pattern of spacers thus recorded is then recorded on the substrate to be used as spacers for use in the liquid crystal panel by peeling off the recording medium from the substrate.

  • Patent number: 6816183
    Abstract: The package of recording media contains a set of recording media which are pre-stacked in a predetermined order is provided to a recording medium holding member so that immediately after the package is opened, the recording media are disposed in a recording apparatus at a time. This package, by avoiding a need of manual stacking of the recording media, lowers a possibility of each recording medium being contaminated with foreign particles so as to reduce resultant image defects. Further, a recording feed cassette stacking the recording media in said manner can achieve the same effect.

  • Patent number: 6801235
    Abstract: It is the purpose of the present invention to provide an image recording method and image recording apparatus for performing high-density recording without degrading the resolution. A desired image is recorded on a recording medium by exposing the image on the recording medium while moving the recording medium in the main scan direction where a toner layer of a transfer sheet is overlaid on an image reception layer of an image reception sheet as well as moving a plurality of laser beam spots arranged on the recording medium in the sub-scan direction orthogonal to the main scan direction. In this practice, a recording process on the transfer sheet is repeated a plurality of times to record a same image repeatedly with transfer sheets replaced after the transfer sheet has been exposed.

  • Publication number: 20040012666
    Abstract: A record head for applying laser light for drawing to a record medium and a record medium are supported so that they can be relatively moved in a main scanning direction and a sub scanning direction along the surface of the record medium through a move guide mechanism. The record head has a laser displacement sensor for detecting the distance to the light exposure position of the record medium in a noncontact manner. A record apparatus has an auto focus mechanism for correcting misregistration between the focus position of the laser light for drawing emitted from the record head and the record medium to a reference value based on the detection value of the laser displacement sensor, so that the focal distance between the record head and the record medium is held good regardless of deformation of a guide rail of the move guide mechanism, etc.
