Thermal transfer color recording device

A thermal transfer color recording device comprising:

• a recording portion for effecting thermal transfer color recording, said recording portion including a platen roller and a thermal head, said thermal head having a plurality of rectilinear heating elements, means for moving said thermal head to selectively press said platen roller to clamp and convey an ink sheet, on which ink of two or more colors is applied respectively on areas nearly equal to or larger than desired recording areas, and a recording paper, between said thermal head and said platen roller;
• a grip roller and a resiliently biased pinch roller located downstream from the recording portion in the recording direction of the recording paper, said grip roller having minute projections on its surface for clamping and conveying the recording paper between the grip roller and the resiliently biased pinch roller;
• means for rotating the grip roller in a clockwise or counter-clockwise rotation, whereby counter-clockwise rotation of the grip roller conveys the recording paper in the recording direction;
• means for conveying said ink sheet between said thermal head and said platen roller so that ink of two or more colors can be applied to said recording paper as the recording paper is conveyed by the grip roller;
• an auxiliary roller located upstream from the recording portion in the recording direction of the recording paper for clamping and conveying the recording paper between the auxiliary roller and the platen roller;
• first transmitting means for transmitting the rotation of the grip roller to the auxiliary roller at a reduced rate in the recording direction of the recording paper;
• and
• second transmitting means for transmitting the rotation of the grip roller to the platen roller at an increased rate in the direction opposite the recording direction of the recording paper.
