<p>PURPOSE:To stop loading immediately by continuing loading while detecting an erroneous insertion lever and detecting an erroneous insertion by means of the same lever. CONSTITUTION:A cassette 8 is loaded on a tray 3 of a cassette holder 2. During sliding the holder 2, an abutting chip 53 of a slider opening lever 51 of a plate 63 is abutted on a cassette shell. The advance of the holder 2 rotates the lever 51 clockwise, and a detection chip 74 of an erroneous insertion detection lever 7 is entered into the hub. When the holder 2 is advanced further, an abutting chip 53 of the lever 51 is fallen into a ditch. The projection shaft of the erroneous insertion detection lever 7 is engaged with the cam groove of a slide plate 4 to move. The lever 7 rotates clockwise and a detection chip 74 is pulled out from hubs of the cassette 8. A plate 63 presses the cassette 8, and the tray 3 goes down to load the cassette on the reel table. In case of erroneous insertion, a projected shaft on a detection lever 7 blocks advance, resulting in preventing an erroneous insertion of the cassette 8.</p> |
