Claims

[Claims for Utility Model Registration] (1) A platen rotatably supported by a pair of left and right fixed frames, a thermal head pressed against the platen, and a thermal head rotated around the fixed frame so as to open the upper part of the platen. A pair of left and right movable frames are provided to be freely movable, a head unit that is rotatably supported by the movable frames and holds the thermal head, a spring member that biases the head unit toward the platen, and a rotatable head unit that is rotatably supported by the movable frames. a camshaft supported by the camshaft, a cam attached to the camshaft, a head up roller that is provided on the rotational track of the cam and pushes up the thermal head that is in pressure contact with the platen together with the head unit; a paper rewind roller rotatably supported by a fixed frame; a pair of left and right paper rewind arms rotatably provided on the fixed frame; and a pair of left and right paper rewind arms rotatably supported by the arms and pressed against the paper rewind roller. and a separation roller that is rotatably provided on the paper rewind arm and separates the pinch roller from the paper rewind roller by engaging with the cam. printer. (2) The thermal transfer printer according to claim 1, wherein the thermal head is a line thermal head with a long printing width.
