Abstract: PURPOSE:To stabilize printing quality as compared with conventional one in a printer. CONSTITUTION:Tension adjusting mechanisms 33, 34 are provided between a cylindrical drum 10 and the supply device 31 of an ink ribbon 3. The tension of the ink ribbon 3 pressed to the cylindrical drum 10 can be kept constant by those tension adjusting mechanisms 33, 34. By this constitution, the friction force between the ink ribbon 3 and image receiving paper 4 is stabilized almost constant. As a result, shift becomes hard to generate between the ink ribbon 3 and the image receiving paper 4 and printing quality is stabilized.

Abstract: PURPOSE:To eliminate the necessity of loading time for an ink ribbon. of a laser sublimation type printer and remove the harmful transfer generated by the contact of an image receiving paper with the ink ribbon for a long time. CONSTITUTION:An ink ribbon 3 is wound on a bobbin 13A and an image receiving paper 4 is fitted on a drum 10. The ink ribbon 3 is pressed in the narrow width to the image receiving paper 4 on the rotating drum 10 by a press bar 14. Laser beam L is guided to the press bar 14 by a laser scanner and condensed on the ink ribbon 3, and printing is carried out on the image receiving paper by light and heat conversion. The time of printing one color image can be shortened by the arrangement, and an image receiving paper fitting mechanism of a drum can be simplified, and also harmful transfer is hard to generate on the image receiving paper, as the ink ribbon is not wound on the rotating drum nor the image receiving paper, and printing of high quality level can be achieved.
