Claims

[Claims for Utility Model Registration] 1. A registration roller for supplying paper between a platen roller and a recording head that are in pressure contact with each other is provided in the paper feed path, and the supplied paper is held between the platen roller and the recording head to produce the above-mentioned recording head. The operation of moving the paper forward a predetermined distance together with the ink ribbon by rotating the platen roller in the forward direction, and the operation of moving the paper back to the reverse feed path by a distance equal to the forward movement distance by rotating the platen roller in the opposite direction. In a thermal transfer recording device that performs transfer by performing the above steps multiple times, a pinch roller is provided on the downstream side of the recording head and presses against the platen roller when the platen roller rotates in the forward direction;
The reverse feed path is provided with a reverse feed roller that feeds the paper backwards, and an auxiliary roller is provided on the upstream side of the recording head, and this auxiliary roller is connected to the first roller that faces the paper feed path away from the platen roller. a second platen roller that presses against the platen roller so as to bias the paper in the tension direction between the registration roller and the pinch roller, and direct the paper to the reverse feeding path when the paper is fed backwards; 1. A paper transport mechanism in a thermal transfer recording apparatus, characterized in that the paper transport mechanism is configured to be movable between the first position and the second position, and is provided with a moving means for moving an auxiliary roller between the first position and the second position. 2. A paper transport mechanism in a thermal transfer recording apparatus according to claim 1, wherein the auxiliary roller is moved by swinging of an arm that pivotally supports both ends of the auxiliary roller.
