ABSTRACT:
A magnetic tape container for use in combination with a magnetic tape duplicating apparatus in which a long, endless, master magnetic tape is circulated to produce many duplicates of the master magnetic tape. The magnetic tape container has most of the long, endless, master magnetic tape in a zigzag fashion for circulating the master magnetic tape through the magnetic tape duplicating apparatus. The magnetic tape container is comprised of a tape case, a feed mechanism having a capstan disposed near the entrance of the tape case, a pinch roller mounted for free rotation on a swing lever being brought into contact with the capstan or retracted from the capstan, provided with at least one annular air guide groove in the circumference thereof. A first tape guide is disposed near the capstan, and a second tape guide is disposed near the pinch roller opposite to the first tape guide to form a gap between the first tape guide and the second tape guide. An air blowing member is disposed near the pinch roller to blow air toward a gap between the second tape guide and the pinch roller so that air blown by the air blowing member flows through the gap between the pinch roller and the second guide and through the annular air guide groove of the pinch roller to impinge on the magnetic tape to separate it from the pinch roller, so that the surface of the magnetic tape facing the pinch roller is not abraded by the pinch roller.
