  • Patent number: 5193007
    Abstract: A heat transfer recording method of transferring the ink of an ink sheet to a recording medium to thereby effect recording of an image on the recording medium is characterized in that the ink sheet is conveyed in the direction opposite to the conveyance direction of the recording medium and recording of an image is effected on the recording medium.

  • Patent number: 5187494
    Abstract: There is disclosed a thermal transfer printer for image recording by ink transfer from an ink sheet onto a recording sheet, which is capable of stable sheet transportation and improvement in image quality. The printer has transport mechanisms for the ink sheet and the recording sheet, a thermal head for heating the ink sheet, and a controller. If a next recording operation is not instructed by the end of a preceding recording operation, the controller starts the transportation of the sheets and at the same time activates the thermal head with an energy smaller than in the ordinary image recording, thus effecting pre-heating of the thermal head prior to the start of the next recording operation.

  • Patent number: 5184151
    Abstract: A thermal transfer recording apparatus, which transfers ink contained on an ink sheet onto a recording medium to record images thereon, and comprises a means for conveying the ink sheet and recording medium; recording means for effecting the ink sheet to record the image on the recording medium; and adjusting means for adjusting the conveyance amount of the ink sheet against the recording medium at the time of starting the next recording action if the recording action is suspended after the unit of a predetermined amount of image data has been recorded by the above-mentioned recording means.

  • Patent number: 5179390
    Abstract: A thermal transfer recording apparatus for image recording on a recording medium by transfer of ink from an ink sheet is taught. This apparatus includes recording means for transferring ink from the ink sheet onto a recording medium to record, a rotary member capable of rotation for transporting the recording medium, and transporting means for transporting the ink sheet with a relative speed with respect to the recording medium, wherein the frictional force between the recording medium and the rotary member is made larger than the shearing force in the ink in the ink sheet during the recording operation.

  • Patent number: 5177499
    Abstract: A heat transfer recording apparatus of the present invention reliably separates an ink sheet and recording paper which have been joined at recording of immediately before from each other when ink of the ink sheet is transferred to recording paper to record an image. More concretely, when an ink sheet and recording paper are transported to record an image of a noticed line, a recording head is heated on the basis of the image data of the line recorded immediately before. As a result, the ink of the ink sheet is melted and therefore the sheet and the recording paper can be separated easily.
