PURPOSE:To enhance printing accuracy and elongate the service life of a thermal head by a method wherein a supporting member, to the basic end side of which a supporting part is provided and to the following end side of which a cleaning pad for cleaning the surface of ink ribbon is arranged, is provided. CONSTITUTION:A pad mounting plate 10, on which a cleaning pad 2 is installed, is arranged to one edge side of the outer periphery of the thermal head inserting port 119 of the ink ribbon cartridge casing 9a. Thus, simultaneously with the inserting movement of a thermal head 3 in the ink ribbon cartridge casing 9a, the cleaning pad 2 is turned about the supporting part 10a of the pad mounting plate 10 so as to be displaced in the ink ribbon cartridge 9a, resulting in realizing the constitution in order to clean ink ribbon 5 just before its contact with the thermal head 3. As a result, the ink ribbon 5 is brought into contact with the thermal head 3 under the condition that the dust and the like adhered to the surface of the ribbon is removed. Accordingly, the enhancement of printing accuracy and the longer service life of the thermal head 3 result. |
