機構。 In a paper feeding means in a thermal transfer printer, etc., paper is fed by frictional drive between a drive roller and a pinch roller that is in pressure contact with the drive roller, and the pressing force of the pinch roller that is in pressure contact with the drive roller is printed as in the case of paper feed. In the paper feed mechanism, the pinch roller is separated from the drive roller after printing is completed in two stages: a state where the pinch roller is separated from the drive roller, a state where the pinch roller is lightly pressed against the drive roller, and a state where the pinch roller is lightly pressed against the drive roller. A paper characterized in that switching between the pressing force and the pressing state of the pinch roller is controlled by a detecting means for detecting three states in which the pinch roller is strongly pressed against the drive roller and a detecting means for detecting the end of the cutter operation. Feeding mechanism.
