<p>PURPOSE:To remarkably reduce the number of components of a mechanism, by driving a tape with one motorm and switching a route for transmitting rotation with a power source of a solenoid and the switching of the direction of rotation of the motor. CONSTITUTION:A torque of a belt pulley 19 is delivered to a winding pulley 22, this torque is delivered with friction through felt washers 25, 26, and a pressing plate 28, a spring 28, and a stripper 29 to a gear pulley 24, and further to a changeover pulley 31 with a gear idler gear 30. Thus, the pulley 31 is rotated and an idler arm 11 is also rotated with a friction torque. An idler 12 abuts on an outer circumference of a reel stand 3 and the idler 12 turns the reel stand 3. In this case, a tape is wound with a winding pulley 23 and the felt washers 25 and 26 while being slipped always. Thus, recording or reproduction can be attained.</p> |
