<p>PURPOSE:To prevent foreign matters such as dust from being invaded in the inside of the set via a cassette loading inlet by locking a shutter except when a cassette is ejected. CONSTITUTION:In loading a cassette 21, while a loading gear 32 is turned in the direction X6, a switching lever 38 is pushed by a switching roller 39 provided to the loading gear 32 and turned once in the direction X6 and restored in the direction X5 by spring (53) action. Thus, the shutter 24 closes automatically the cassette loading inlet. On the other hand, in ejecting the cassette 31, the converse operation to the loading is conducted and the loading gear 32 is turned in the direction X5. Thus, a cassette holder 27 is floated once in the vertical direction and carried horizontally in the direction X2.</p> |
