<p>PURPOSE:To simplify the support structure and also facilitate an easy setting of the shift stroke for an auto-stop sensor, by supporting the auto-stop sensor to a support shaft different from that for a reel drive disk in such way as always to secure a rotation and rocking. CONSTITUTION:The plural positions having different relative distances to an auto- stop sensor 7 are set for a working gear 10 which is driven by a motor 14. A rotary rocking can be given to the sensor 7 with a rocking cam 10a and the pushing projections 11d and 11d during a rotation of a reel drive disk 11a in a range during which no function force is given to the means to be actuated and regardless of the position of the gear 10. In addition, if the rotation of the disk 11a is stopped at the termination of a tape, the tape is pushed back toward the disk 11a with the cam 10a. After this, the function force is given to the means to be actuated.</p> |
