Color printer

Abstract

Abstract PURPOSE: To reduce consumption of a ribbon, by a method wherein a ribbon is encased in a cassette with a mark for detecting a color demarcation provided for the ribbon, and a reel in the cassette is driven by a signal of detecting the mark and a signal of detecting the rotational position of a platen. CONSTITUTION: When a motor 9 is driven, the platen 2 starts to be rotated in the direction of the arrow by a belt 10, and a picture signal is simultaneously impressed on a thermal head 3. When the platen 2 is rotated and a printing paper 14 strikes against the thermal head 3, the ribbon 4 contained in the cassette 5 is pressed between the head 3 and the paper 14 wound around the platen 2, so that the ribbon 4 is let off from a supply reel 5a and taken up by a take- up reel 5b concurrently with the rotation of the platen 2. When the tip of the head 3 is heated by a voltage impressed in correspondence to the picture signal, a sublimable dye in the ribbon 4 is sublimed, is deposited on the paper 14 and dispersed to perform transfer.
