Abstract

PURPOSE:To enhance printing quality by certainly adhering ink to a paper, by mounting a head provided with a heat generator imparting heat to an ink ribbon and a roller for pressing the ink ribbon so as to contact the same with the paper at a position separated by a release distance from said head. CONSTITUTION:A head 2 and a roller 3 are mounted on a carrier 6 and an ink ribbon 1 is allowed to run while pressed to the paper 5 on a platen 4 by the edge (position A) of the head 2 and the roller 3 (position B). The carrier 6 moves left and right along the platen 4 in matching relation to the printing request from a control part. The ink ribbon 1 receives heat from the heat generator provided to the leading end of the head 2 and adheres molten ink to the paper 5 during the movement up to the position B where the ink ribbon is pressed by the roller 3. Since the distance C between the positions A, B becomes a release distance, by properly setting the position of the roller 3, the release distance C can be adjusted freely. For example, when the ink adhering time of the ink ribbon 1 is long, the release distance C is made long to make it possible to obtain good printing quality.

[Problems to be Solved by the Invention] Conventional thermal printers have an ink ribbon.
After heat is applied to the paper 5, the ink ribbon 1 and the paper 5 are
Since there is not a sufficient peeling distance until the ink ribbon separates, there is a drawback that, depending on the performance of the ink ribbon 1, printing quality may deteriorate. This depends on the time required for the ink on the ink ribbon 1 to firmly adhere to the paper 5 after being melted by heat. Due to this drawback, in the conventional thermal printer described above, an ink ribbon having a short ink adhesion time had to be selected.

FIG. 1 shows a schematic front view of an embodiment of the present invention. The head 2 and rollers 3 are attached to the carrier 6, and the ink ribbon 1 is pressed against the paper 5 on the platen 4 by the edge (position, to) of the head 2 and the roller 3 (position B) and runs. The carrier 6 moves left and right along the platen 4 in response to a printing request from a control unit (not shown). The ink ribbon 1 is heated by a heating element at the tip of the head 2, and causes melted ink to adhere to the paper 5 while moving to a position B where it is held by a roller 3.
