Abstract
There is disclosed a thermal transfer recording apparatus utilizing an ink sheet and a recording sheet, provided with a thermal head, an ink sheet feeding mechanism, and a recording sheet feeding mechanism, in which, after the image recording, the ink sheet is fed at a speed lower than that of the recording sheet, thereby preventing the formation of creases or slack in the ink sheet.

A thermal transfer recording apparatus for image recording by transferring ink of an ink sheet to a recording medium, comprising:
- recording means for acting on said ink sheet thereby recording an image on said recording medium;
- ink sheet feed means for feeding said ink sheet;
- recording medium feed means for feeding said recording medium;
- and
- controlling means for controlling which cause said ink sheet to be conveyed at a speed lower than that of said recording medium in a predetermined direction when said recording medium is conveyed following image recording by said recording means.
A thermal transfer recording apparatus for image recording by transferring ink of an ink sheet to a recording medium, comprising:
- recording means for acting on said ink sheet thereby recording an image on said recording medium;
- ink sheet feed means for feeding said ink sheet;
- recording medium feed means for feeding said recording medium;
- and
- controlling means for controlling which cause said ink sheet to be conveyed at a speed higher than that of said recording medium in a predetermined direction when said recording medium is conveyed following image recording by said recording means.
A thermal transfer recording apparatus for image recording by transferring ink of an ink sheet to a recording medium, comprising:
- recording means for acting on said ink sheet thereby recording an image on said recording medium;
- ink sheet feed means for feeding said ink sheet;
- recording medium feed means for feeding said recording medium;
- and
- control means for feeding, during image recording with said recording means, said ink sheet with a speed equal to 1/n (n>1) of that of said recording medium, and, in a forward feeding of said recording medium in a forward direction toward a discharge end with a speed V.sub.PF after image recording, feeding said ink sheet with a speed V.sub.IF =V.sub.PF /n.sub.IF, wherein n.sub.IF is equal to n during the image recording.
A thermal transfer recording apparatus for image recording by transferring ink of an ink sheet to a recording medium, comprising:
- recording means for acting on said ink sheet thereby recording an image on said recording medium;
- ink sheet feed means for feeding said ink sheet;
- and
- recording medium feed means for feeding said recording medium;
- wherein said ink sheet is fed during image recording with said recording means, with a speed equal to 1/n (n>1) of that of said recording medium, and is fed, at the feeding of said recording medium with a speed V.sub.PF toward a discharge end after the image recording, with a speed V.sub.IF =V.sub.PF /n.sub.IF (n.sub.IF being larger than n during the image recording), in a direction opposite to a direction toward the discharge end.
A thermal transfer recording apparatus for image recording by transferring ink of an ink sheet to a recording medium, comprising:
- recording means for acting on said ink sheet thereby recording an image on said recording medium;
