Abstract

PURPOSE:To reduce the running load, by forming the suction hole in the fixed guide so that the air suctioned through the suction hole can be discharged from the gap between the fixed guide and the rotating guide. CONSTITUTION:When the upper cylinder 20 is turned, the air present in the gap between upper and lower cylinders 20 and 14 is discharged with the centrifugal force by the revolution of the upper cylinder. But, the suction hole 29 of the suction control plate 28 provided under the lower cylinder 14 and the hole 27 formed at the lower cylinder 14 always make suction, the air discharge is always kept from the gap between the upper cylinder 20 and the lower cylinder 14, resulting that the force floating the tape from the cylinder external circumference can keep at all times. That is, the air is subject to centrifugal force through the revolution of the upper cylinder 20, and the upper cylinder 20 and the head disc 19 make fan operation, allowing to suction from the suction hole 29 toward the arrows (a) and (b), and to deliver from the part between the lower cylinder 14 and the upper cylinder 20 toward the arrows (a) and (b).
