Claims (1)

[Claims for Utility Model Registration] 1. A thermal head, a head mounting member to which the thermal head is attached, and a platen roller for sandwiching and pressing supplied paper and ink ribbon with the thermal head to perform thermal transfer. , comprising a transfer path for transferring the thermally transferred paper, and an ink ribbon take-up roller for separating, transferring and winding the ink ribbon after the thermal transfer in contact with an ink ribbon separating member in a direction different from the paper transfer direction. In a thermal transfer printer, the ink ribbon separation member is in the form of a plate that is long in the width direction of the ink ribbon, and is attached to the head mounting member so as to be rotatable in the winding direction of the ink ribbon, so that one long side is A separation plate that applies tension to the ink ribbon by sliding across the ink ribbon after thermal transfer, and a separation plate that is bent integrally from one long side of the separation plate to the winding side of the ink ribbon. When the winding force of the ink ribbon is weak and the rotation angle of the separating plate is small, the ink ribbon is slidably pressed by a bent piece. A thermal transfer printer comprising a tension applying section having a larger pressing area on both sides in the width direction than the center part and capable of applying tension to both sides in the width direction of an ink ribbon. 2. A thermal head, a head mounting member to which it is attached, a platen roller for sandwiching and pressing the supplied paper and ink ribbon with the thermal head to perform thermal transfer, and for transporting the thermally transferred paper. In a thermal transfer printer equipped with a transfer path and an ink ribbon take-up roller that separates, transfers and winds the ink ribbon after thermal transfer in a direction different from the paper transfer direction in contact with an ink ribbon separating member, the ink ribbon is separated. The member has a plate shape that is long in the width direction of the ink ribbon, and is attached to the head mounting member so that it can rotate in the winding direction of the ink ribbon, so that one long side holds the ink ribbon after thermal transfer horizontally. A separation plate that is cut and slidably pressed to apply tension to the ink ribbon; and a separation plate that is bent and extends from one long side of the separation plate to the ink ribbon winding side, and is used for winding the ink ribbon. When the force is weak and the rotation angle of the separation plate is small, the ink ribbon is slidably pressed by a bent piece. It has a tension adding part that has a larger pressing area than the ink ribbon and can add tension to both sides of the ink ribbon in the width direction, and a tension adding part that is attached to the head attachment member and that is attached to the head mounting member and that is moved in the opposite direction to the winding direction of the ink ribbon. and a spring that presses one long side of the separation plate against the ink ribbon after thermal transfer so as to be able to slide across the ink ribbon and to change the pressing angle, thereby tensioning the ink ribbon. A thermal transfer printer.
