<p>PURPOSE:To simplify a constitution, to ensure cassette loading operation and to improve the reliability for a cassette loading mechanism, by moving a cassette holder by opening/closing a front door to operate a double speed mechanism. CONSTITUTION:A cassette is put into a cassette holder 7, and a front door 14 is turned counterclockwise while stretching a spring 16. Thus a rotary arm 11 is also turned by a driving pin 15 loose fitted into a slit 13, and a cassette holder 7 is guided by pins 9 and 10 loose fitted into guide holes 3 and 4 of a chassis 1 and shifted to the left by a pin 8. Then the pin 8 is put into a guide hole 2. In this case, the holder 7 is accelerated double and moved faster than the door 14. Furthermore the holder 7 goes down along the holes 3 and 4 after moving to the left. A hook member 5 is turned clockwise by a pin 10 while stretching a spring 6. When the pin 10 passes through a hook part, the pin 10 is locked to hold the holder 7 at the cassette loading position. At the same time, the door 14 is closed.</p> |
