<p>PURPOSE:To enable the operation of a tension servo means to be performed according to the loading operation, by providing a loading means and tension servo means in such a way that they are latched on the way of the unloading operation and the loading starting position. CONSTITUTION:Accompanied with the movement of a loading pole 4 to the loading direction, the latch point of the pole 4 moves to the tip along a projected latch section 10a, a tension lever 10 gradually turns, and the tension lever 10 is turned to the operating position when the pole 4 moves to the position on the way of almost intermediate position, into latch, and the tension servo mechanism is converted into operating mode gradually accompanied with the loading operation. When the loading pole 4 furhter moves to the final position, the tension servo mechanism is in operating state and a back tension is given to the magnetic tape 21 with the operation of a hand brake 13.</p> |
