<p>PURPOSE:To prevent an inner rid from being hooked and to miniaturize and simplify a device by pressing the opened inner rid from an upper part and sliding the inner rid into the lower side of a dust preventing door at the time of ejecting a cassette. CONSTITUTION:When the cassette 10 is loaded, a cassette holder is moved downward along guide grooves 3a-3c, and at the time of completing the loading, the inner rid 10b of a rid 10a is opened. At the time of ejecting the cassette, the cassette holder is moved upward and the inner rid 10b is pressed from the upper part by a guide plate 5 and slided into the lower side of the dust preventing door 9 simultaneously with the ejection of the cassette in the left direction. Thereby, the inner rid can be prevented from being hooked by the dust preventing door at the time of ejecting the cassette and only small pressing force for pressing the rid is required, so that the device can be miniaturized and simplified.</p> |
