<p>PURPOSE:To reduce wow and flutter and to improve the quality of a reproduced sound in a reproducing mode, by driving a take-up reel by a rotary wheel which turns while sliding with a capstan. CONSTITUTION:A spring is hooked between levers 7 and 8, and these levers are sprung to increase the included angle of them. Therefore a floating wheel 6 is pressed light to the outer circumference of a rotary wheel 4 unified with a pulley 4b and a reel drive disk 3a respectively. When a capstan 10 is turned counterclockwise, the pulley 4b and the wheel 4 are turned also in the same direction. As the wheel 6 is connected frictionally to the lever 7, the wheel 6 is shifted to the right and touches the outer circumference of the disk 3a to drive it counterclockwise. The hub of a cassette is fitted to reels 2 and 2a and then driven to take up a magnetic tape.</p> |
