<p>PURPOSE:To pull out and store a cassette tape without generating unneeded tension and a sag by adjusting damping force to a supply reel turntable by controlling the turning of a tension lever according to the movement of tape pull-out pins. CONSTITUTION:As rotary ring 6 turns counterclockwise, tape pull-out pin tables 3a and 3b move to pull out a tape in a cassette by pull-out pins 4a and 5a, and 4b and 5b. Tension lever 7 whose lock has been released by this moving pin table 3a will not move by the lock of pin 27 and no damping force is applied to a supply reel turntable, so that the tape applied with no unneeded tension will smoothly be pulled out near a pull-out end adjacent position. Then, rotary cam 20 is turned by projection 30 of ring 6 to move pin 27 of cam 20, and arm 7 released from the lock turns to apply damping force from a tape-loading end adjacent point to the supply reel turntable, thereby pulling the tape out by adequate tension.</p> |
