<p>PURPOSE:To miniaturize the entire device and to attain the light weight by using a cam so as to drive a pinch roller arm. CONSTITUTION:In loading a cassette, the loading is sensed by a cassette sensing switch and a mode motor control circuit drives a mode motor forward. The cam 2 is driven in the direction of arrow A by the forward drive and a Geneva gear engaged with the cam 2 drives a tape drawing member stored in the inside of the cassette and a gear 3 to wound the tape on a cylinder thereby positioning the tape lead member. The gear 3 is driven in the direction of arrow B, a gear 6 is driven in the direction of arrow C via engaged gears 4, 5, one end of a tape drawing pin 6-1 provided incorporatedly with the gear 6 is engaged with a cam 8-2 of the pinch roller arm 8 to drive the arm 8 thereby moving the pinch roller 7 provided freely turnably to one end of the arm 8 in the vicinity of the capstan and the loading is finished.</p> |
