<p>PURPOSE: To prevent a loading fault by adequately setting the shape and arrangement of an elastic member for double-action operation of a loading mechanism and preventing this double action operation from being brought into action during the course of loading. CONSTITUTION: A loading lever 70 is rotated counterclockwise by rotation of a cam gear 80, and pins 74, 76 act on long holes 54a, 64a to rotate loading arms 54, 65 in arrow A, B directions around a supporting shaft 60 respectively. Pole bases 10, 20 move along curved long hole-like guide rails disposed at the chassis by receiving the movement of the loading arms 54, 64 via repeating arms 52, 62 and transfer the tape from a cassette to a head drum to execute loading. The pins 74, 76 are respectively mounted via double action levers 71, 72 at the loading lever 70 to have the double action operation executed in the last of the loading by their elasticity. The elasticity does not, however, act during the course of the loading on account of the reaction direction of the load.</p> |
