Abstract
Proposed is a dye-sublimation printer, and more particularly to a dye-sublimation printer that can systematically control upward and downward movements of a pick-up roller, upward and downward movements of a platen roller, and driving of a take-up reel gear according to forward and backward movements of a slide plate.
Claims10
A dye-sublimation printer, comprising:
- a feed roller including one side combined with a feed gear;
- a swing lever combined with the feed roller so as to swing in two directions, and having a swing control groove formed horizontally;
- a take-up reel gear combined with a winding reel on which a ribbon is wound;
- a swing gear combined with the swing lever so as to engage with the feed gear, and configured to engage with or disengage with the take-up reel gear selectively according to the two swing directions of the swing lever;
- and
- a swing controller configured to control the swing lever,
- wherein the swing controller includes a projection disposed at a front end of a discharge side and an escape groove disposed apart from a supply side, and
- wherein the swing control groove is configured to catch the projection.

A rewinding correction method used in a dye-sublimation printer configured to form an image on a recording medium using a ribbon and configured to relocate a starting point of the recording medium and the ribbon, the method comprising:
- step 1) moving a platen roller downward so to be spaced apart from a head;
- step 2) reversely rotating a feed roller so that the recording medium moves backward through a space between the platen roller and the head, thereby being transferred to a starting point of printing;
- step 3) rotating the feed roller, with the platen roller and the head spaced apart, so that the ribbon is wound and the recording medium moves forward toward a discharge side;
- step 4) reversely rotating the feed roller, with the ribbon being in a static state, so that the recording medium moves backward toward the discharge side, thereby being retransferred to the starting point of printing;
- and
- step 5) winding the ribbon and performing printing, with the platen roller being in a state of coming into contact with the head after moving upward, while the recording medium is moving forward toward the discharge side.
