<p>PURPOSE:To obtain a high negative pressure even with a blower of small capacity, by providing a shield body being an enclosed construction except a tape passing section for the surrounding of a takeup reel winding a tape with a negative air pressure. CONSTITUTION:The takeup reel 12 is fitted to a shaft of a motor 15 and provided with a housing 3 with slits 10 and a reel plate 4, and the shield body 5 having a tape port 6 on which the tape 2 passes is fitted to the surrounding of the plate 4 by leaving a minute gap 7 and the blower is provided at the tip of the arrow 14. When the blower is operated, air almost flows from the port 6 because of the narrow gap 7 and the magnetic tape 2 is wound by being introduced on the housing 3 along this air flow. Since the shield body 5 is provided, the amount of flowing air is very less and a high negative pressure is obtained for the reel 12 even with the blower of a small capacity.</p> |
