<p>PURPOSE:To perform the loading without slackening and damage of a tape by changing revolving torque of a reel in the midst of moving guide posts from their 1st positions in a cassette opening part to 2nd positions of completing winding around a rotary drum. CONSTITUTION:When a cassette 1 is loaded, a reel motor 47 is electrified to be given prescribed back torque. Then, a loading motor 22 is electrified, and the tape 4 is drawn out of the cassette by the posts 5, 7, 9, 10, 15 and 16. In this case, the reel motor 47 is given the weakest possible back torque. The loading is progressed, and when a detecting member 27 is passed through a photo interruptor 25, the back torque given to the reel motor 47 is increased. On the other hand, the photo interruptor 25 is disposed in such a position that a position of each post prior to reaching its final position can be detected, thus enabling the loading without slackening and damage of the tape.</p> |
