Go back and forth. The recording head 30 is a known laser light emitting means, such as that shown in FIGS. 11 and 12 described above, in which a laser light generator and an optical system are housed in a housing. A semiconductor laser element (not shown) that generates light and an optical system (not shown) are incorporated. The second drum 24 is rotatably supported by a supporting device (not shown) independently of the lead screw 26.

The semiconductor laser element built in the recording head 30 emits a laser beam L, and the optical system has an imaging lens. The laser beam L emitted from the semiconductor laser element is an ink on the second drum 24. It is configured to focus on the inside of the ribbon A. The recording head 30 is fixedly mounted so that the semiconductor laser device and the optical system are always oriented in the following directions. The direction means that the laser beam emitted from the semiconductor laser element is directed toward the contact point between the first drum 22 and the second drum 24 and inside the ink ribbon A located at the contact point between the first drum 22 and the second drum 24. It is the direction to focus on. As shown by arrow V in FIG.
When the first drum 22 around which the ink is wound is driven by a rotation driving device (not shown) to rotate, the second drum 24 around which the ink ribbon A is wound accordingly causes contact friction with the first drum 22 to cause the first drum 22 to move. It rotates in the direction opposite to the rotation direction (direction of arrow W).
