。FIG. 4 shows a specific example of the ribbon cassette 5 described above, and the ink ribbon 6 stored in the ribbon cassette 5 has its intermediate portion externally exposed through the ribbon outlet 5A formed on the front surface of the ribbon cassette 5. The ink ribbon 6 located outside is drawn into the ribbon cassette 5 from the ribbon intake port 5B. The ink ribbon 6 is caused to travel by rotation of the rotary drum 15 in the direction of the arrow. Further, a recess 16 is formed in the ribbon cassette 5 on the back of the ink ribbon 6 facing the outside.1. The thermal head 8 faces into this recess 16. Furthermore, the carriage 4, which is moved by the wire 17 along the support shaft 3 in FIG. It moves toward and away from the platen 1 by the action of a spring 13 and a solenoid 14 shown in FIG.

As shown in Figure 2, polyethylene terephthalate (P
The ink layer 21 is laminated on a base layer 20 made of a material such as ETP, but the tensile force for peeling the ink ribbon 6 thus configured from the recording paper 19 is Since the ink ribbon 6 is not easily peeled off from the recording paper 19 due to only the winding force of the rotating drum 15 due to the movement of the carriage 4 along the shaft 3, the recording paper 19
The ink left on the ink and the ink layer 2 of the ink ribbon 6
There was a problem in that the ink running out between inks of No. 1 became poor, and good print quality could not be maintained.

字品質を維持することができる。According to the above-mentioned configuration, when the ink ribbon 6 is pressed against the recording paper 19 by the thermal head 8 so that the ink layer 21 thereof faces the surface of the recording paper 19, a heating element (not shown) is activated at a specific location of the thermal head 8. ), the ink in the ink layer 21 in the area facing the heated heating element becomes molten, increasing its adhesion to the recording paper, and the ink layer 2 in this molten state becomes molten.
The release layer 22 at the portion facing the ink No. 1 contracts due to the heat of the +IQ heating element. As a result, the ink in the molten ink layer 21 moves together with the contracted release layer 22 and is separated from the solid ink, which improves the separation between the molten ink and the solid ink. . Therefore, even if the ink ribbon 6 is wound up only by the ribbon cassette 50 and the rotating drum 15, the recording paper 19
The ink in the ink layer 21 of the ink ribbon 6 that has peeled off is drawn toward the recording wi 19 side. The @ condition can be avoided and good print quality can be maintained.
