<p>PURPOSE: To reduce the number of parts and to facilitate assembly also by using a single spring and pressing a tape guide pulling out a tape to a stopper. CONSTITUTION: A drive gear 8 is rotated by a motor, and an arm 19 is turned by the rotation through intermittent gears 8T, 19W, and the arm 20 is turned through gear parts 19t, 20t. By the turning of the arms 19, 20, tape guides 6, 7 are moved through joints 12, 16, and the tape is pulled out from a tape cassette by the movement of the tape guides 6, 7 to be wound round a head cylinder 5. By the turning of the drive gear 8, a torsion spring 18 is moved between the arms 19, 20 through a boss 17a fitted in a cam groove 8a and the arm 17, and the tape guides 6, 7 are press-fixed to the stopper 4 by pressing force of the spring 18.</p> |
