Claims (1)

[Claims for Utility Model Registration] 1. A thermal head that selectively applies heat pulses to an ink donor film as a thermal transfer recording medium fed out from a supply roll, and a thermal head that presses the ink donor film and paper in a superimposed state against the thermal head. , a platen roll for transferring the ink applied to the ink donor film in the area heated by the thermal head onto paper, and a winder for winding up the ink donor film after passing between the thermal head and the platen roll. 1. A thermal transfer recording apparatus comprising: a taking mechanism; and a tension applying means for applying a different tension to the ends of the ink donor film compared to the center thereof. 2. Utility model registration claim 1, characterized in that the tension applying means applies stronger tension to both sides of the ink donor film existing between the platen roll and the winding mechanism than to the center part. The thermal transfer recording device described in Section 1. 3. The thermal transfer recording device according to claim 2, wherein the tension applying means is a peeling member for peeling the ink donor film from the paper. 4. A utility model registration claim characterized in that the tension applying means applies stronger tension to the center of the ink donor film existing between the platen roll and the ink donor film supply mechanism than to both sides thereof. The thermal transfer recording device according to scope 1.
