<p>PURPOSE:To improve the running efficiency of a tape by driving a pair of reel stands for feeding and winding by a driving roller, which is provided separately in stead of the fly-wheel of a capstan, and causing the capstan unit to run the tape only in a fixed speed. CONSTITUTION:Driving rotor 13 having gears 19, 21 and 23 inside is arranged between reel stands 1 and 2 so that driving rotor 13 can be rotated by axis 14. Gears 19, 21 and 23 are supported rotatably on the arm of rotary material 18 which is supported rotatably on axis 14. In the neutral position of the figure, gear 23 is geared with axial gear 13d of rotor 13 and gear part 6a of reel stand 2; and when rotor 13 is rotated in the left direction by belt 17 from motor 15, reel stand 2 is decelerated and rotated in the left direction, and tape 9 fed from capstan 11 and pinchroller 12 is wound. When operation part 18a is rotated in the right direction, gear 21 rotates reel stand 2 in a high speed in the left direction through gear part 6a and gear 19, and the tape is wound in a high speed. When operation part 18a is rotated in the left direction, gear 19 is geared with gear part 16 of reel stand 1 to rotate reel stand 1 in a high speed in the right direction, and the tape is rewound.</p> |
