<p>PURPOSE:To surely open a lid by operating an eject lever in a direction that it is detached from a front surface at the time of loading a cassette. CONSTITUTION:When the cassette 1 is inserted in a cassette holder 2, it advances while it contacts with a slider 56 and the holder 2 and slider releasing ribs 9 and 10 push up locking members 61 and 62. Then, the locking of the slider 56 is released. Slider locking parts 11 and 12 are started to abut on abutting parts 53 and 54 and the boss 13a of the eject lever 13 is started to abut on a cassette lid 55. When the cassette 1 is pushed in further, the slider 56 is stopped and only the cassette 1 advances. Then, the slider is perfectly opened. The lever 13 is turned anticlockwise because the boss 13a is pressed by the cassette lid 55. When the cassette 1 is pushed in further, the guide pin 13b of the lever 13 is moved to a start switch 26, the switch 26 is turned on and a motor 29 is rotated. Then, a worm wheel 31 is rotated. A turning arm 33 abuts on a loading finish switch 28, the motor 29 is stopped and the lid 55 is opened. In such a way, the lid is surely opened.</p> |
