<p>PURPOSE:To improve the space factor and to promote the dust proof effect during the recording and reproducing and also to display the operation state on the back by providing a mechanism for closing a door after turning inside out by moving a rotary shaft of the door from a top end to a bottom end at the time of loading a cassette. CONSTITUTION:When the cassette 16 is inserted, driving pins 15a and 15b of a loading mechanism are positioned at a'-c' relative to right and left saucer arms 12 and R9 respectively. When the cassette is detected at a', the mechanism 15 is automatically operated to move the cassette to a loading point e'. By turning the arm R9 between b' and c', a reversing spring 11 is changed in its action in the direction from C to E, and the door 1 which has been raised up to a door guide 14 around a bearing 1a is revolved around a rotary shaft of door arms 3 and 4 to turn inside out and then operate to close a cassette window 2a via the arm 12, an arm 7 and a lever 13, etc., during a positional variation absorbing period of c' and d' and until e'.</p> |
