<p>PURPOSE:To enable a loading by releasing the brake applied to a feeding reel base and drawing out a tape from the feeding reel side, when the tape is not being wound to the take-up reel side at the loading time. CONSTITUTION:A rotary head drum 5 is freely rotatably mounted on a fixed chassis 2. The feeding reel base 8 and the take-up reel base 9 are freely rotatably mounted on a movable chassis 3 moving back and forth against the fixed chassis 2. These feeding reel base 8 and take-up reel base 9 are rotated by an oscillating gear 19 which is made so as freely to rock on the fixed chassis 2. The tooth part 34b of a brake arm 34 applying or releasing the brake for the feeding reel base 8 is provided on a gear 81 at the input side of the feeding reel base 8, and a pawl part 34c of the brake arm 34 is provided on a ratchet gear 83 of the feeding reel base 8, so as to freely engage and disengage respectively. A driving lever 31 to return the brake arm 34 back to the initial state is provided at the side of the movable chassis 3.</p> |
