Abstract
A thermal transfer type printing apparatus includes a monochromatic printing section and multi-color printing section. The monochromatic printing section includes a thermal head unit for thermally transferring an ink layer of a black ink ribbon onto a paper sheet according to a black image signal. The multi-color printing section includes a thermal head unit for successively transferring cyan, magenta and yellow layers of a multi-color ink ribbon in an overlap state onto the paper sheet according to image signals for the respective colors.
Claims5
A thermal transfer type printing apparatus comprising:
- means for transporting a paper sheet along a transport path;
- a mono-color printing section disposed on said transport path and including a plurality of first heating elements selectively energized according to a first color image signal in a state urging a monochromatic ink ribbon having a one color ink layer against said paper sheet, the ink layer of said ink ribbon being thereby transferred onto said paper sheet according ro selective energization of said first heating elements;
- and
- a multi-color printing section disposed on said transport path after said mono-color printing section and including a plurality of second heating elements selectively energized according ro each of a plurality of second image signals for respective different colors in a state contacting a portion of multi-color ink ribbon having color ink layers of said different colors which are arranged in a predetermined order, on said paper sheet passed through said mono-color printing section, the color ink layers of said multi-color ink ribbon being successively transferred in a overlap state onto said paper sheet according to selective energization of said second heating elements.
