<p>PURPOSE:To prevent larger friction than required, of a recording medium and an upper drum, and also to make the recording medium run stably by moderately energizing the recording medium to a guide body, by rotating the upper drum by frictional force against the recording medium. CONSTITUTION:A titled device consists of a rotating member 14 having a head 13, a fixed lower drum 12 holding a guide body 12a for guiding a recording medium, and an upper drum 11 rotating against the lower drum 12 by frictional force against the recording medium. By this constitution, when the recording medium is shifted along with the guide body 12a, the recording medium is energized to the guide body of the lower drum 12 by frictional force of the recording medium and the upper drum 11, and runs stably. Also, the upper drum 11 rotates at a speed being nearly equal to a shifting speed of the recording medium, therefore, no immoderate external force is put on the recording medium, and deterioration, etc. are not caused.</p> |
