<p>PURPOSE:To easily load and unload a cassette with a simple constitution by constituting such that due to the turning of a cassette lid opening link engaged with a cam a flat spring is operated with respect to the cassette after and before a slide plate moves. CONSTITUTION:When a cassette holder 2 is inserted to advance the slide plate, its cam 9 pushes the roller 11 of the holder to drop the holder. An opening cam 10 pushes the projection 13 of the lid opening link 12, which rotates counterclockwise with a shaft 8b as a center. A pressing part 13 pushes the projection 17 of the flat spring 15, and the top of the part 14 pushed the cassette, thereby preventing a unnecessary oscillation. When the cassette is ejected, the pressing of the spring 15 is eliminated due to the retreat of the slide late. The cassette is ejected with a slight force. The simple constitution minimizes the oscillation when the cassette is loaded and lightens force when the cassette is ejected.</p> |
