<p>PURPOSE:To surely prevent a magnetic tape from being broken by the movement of a cassette at the time of drawing out the magnetic tape by providing an engaging and disengaging means for performing the engaging and disengaging of a motor gear and a moving gear by inerlocking with the engaging and disengaging of 1st and 3rd levers. CONSTITUTION:After setting a cassette on a loading position, a cam gear 20 rotates in an A direction by rotating a driving motor and the 1st lever 24 turns clockwise centering around a supporting shaft 25. With the turning of the 1st lever 24, an engaging pin 52 is engaged with a release groove 51 and the 3rd lever 50 turns counterclockwise centering around a supporting shaft 41, so that the meshing of the motor gear 46 with the moving gear 42 is released. The pin 52 is completely separated from the groove 51 on this side where the lever 50 abuts on a stopper pin 45. With the rotation of the gear 20, the 2nd lever 30 turns counterclockwise centering around a supporting shaft 31 and a plate 34 moves in a B direction and the magnetic tape in the cassette is drawn out. Thus, the tape is surely prevented from being broken by moving cassette at the time of drawing out the tape.</p> |
