ル印字装置。[Claims for Utility Model Registration] Printing is performed by moving the printing head together with the carriage while in contact with the printing paper via the thermal ribbon, and the thermal ribbon is moved in response to the movement of the carriage in the printing state. A thermal printing device that takes up the thermal ribbon includes a ribbon take-up member provided on a carriage to be engaged with a ribbon spool that takes up the thermal ribbon, and a ribbon take-up member provided on the carriage and connected to the ribbon take-up member directly or through an intermediate mechanism. , and a ribbon take-up motor connected in such a manner that rotational movement does not slip in the rotation transmission system, and the tensile force acting on the thermal ribbon due to winding by the ribbon take-up motor is applied in the printing state. The driving torque of the ribbon winding motor is set so that it is always smaller than the frictional force generated between the thermal ribbon and the printing paper, and larger than the force required to peel off the thermal ribbon from the printing paper after printing. A thermal printing device characterized by:
