<p>PURPOSE:To use the width of a cassette effectively, by selecting the position of a tension post in the cassette so that the effect on the other post can be reduced in a home-use VTR. CONSTITUTION:In an unloading operation, a ring pin of the lower end of a loading ring 26 abut to a pin latch 46a formed to the tip of a tension release plate 46 having a curved part. When the loading ring 26 turns, the release plate 46 is depressed on a ring pin 51 and is turned against a release spring 48 and the plate 46 depresses a release pin 50. A tension lever 44 turns around a lever shaft 41 together with a lever 37. Since the lever 37 is latched with a stopper pin 52 of a base, the tension lever 44 turns against a spring 45 by taking a relay pin 43 as a center and then, the unloading is finally finished.</p> |
