<p>PURPOSE: To enable the reduction of the number of components and to attain the reduction of the assembly man-hour by directly driving a reel base for the rotation in accordance with the required operation. CONSTITUTION: In the case of fast forward mode, a pawl 111 of a pulley 107 for the motive power interruption and a pawl 111 of the reel base 102 are moved in the direction E so as to be engaged with each other, and the rotational force of a capstan motor is transmitted to the pulley 107 and the reel base 102 in the manner of direct coupling. Whereas, the rotating direction of a pulley 106 becomes the direction of tape feeding rotation, and the pawl 111 of the pulley 107 and the pawl 111 of the reel base 102 are moved in the direction F so as to be away from each other, then the pulley 106 and a reel base 101 become independently rotatable and the rotational force of the motor is interrupted by the pulley 106, thereby the reel base 101 becomes the idling state and the fast feeding is made at high speed. In the case of rewinding mode, on the other hand, the rotating direction of the pulley 106 becomes the direction of tape taking up, and a pawl 111 of the pulley 106 and a pawl 111 of the reel base 101 are moved so as to be engaged with each other, then the pulley 106 and the base 101 become integrally rotatable, thereby the rotational force of the motor is transmitted to the pulley 106 and the base 101 in the manner of direct coupling.</p> |
