<p>PURPOSE:To attain smooth tape feed by providing an opening part for suction force adjustment, that communicates with a vacuum column adjoining to a take-up side reel, near the bottom part of a vacuum column adjoining to a supply side reel. CONSTITUTION:Opening 10 is provided that links vacuum columns 7 and 8 and adjusting opening width E equalize the internal pressure of the 1st vacuum column 7 to that of the 2nd vacuum column 8. Consequently, when magnetic tape 3 led out of supply side reel 1 is wound around take-up side reel 2 by way of magnetic head 6 following guide roller 4, tape 3 can smoothly be led in both the columns.</p> |
