<p>PURPOSE:To stick by pressure a slider onto a catcher with high accuracy by constituting the loading device of a VTR with a tape extraction post arranged respectively to two loading rings. CONSTITUTION:When the loading of the magnetic tape to the VTR is started, a loading gear 11 is turned in the direction of arrow A and a loading ring 9 is turned in the direction of arrow B. An auxiliary gear 15 and a small diameter gear 16 start meshing with each other and the meshing between the outer diameter gear 9a of the loading ring 9 and the loading gear 11 is released. In this case, the meshing deviation between the small diameter gear 16 and the auxiliary gear 15 is absorbed by a spring 17 and the gear reduction ratio is changed to slow down the turning speed of the loading ring 9, the torque is increased and the sliders 3, 4 are pressed onto the catcher by a large force. In this case, since the sliders 3, 4 are fixed respectively to the loading rings 8, 9, they are pushed with equal force. Thus, the slider is fixed onto the catcher with high accuracy and large pressing force.</p> |
