<p>PURPOSE:To inhibit a case where the 2nd cassette is inserted by a fixed extent or more and to protect the mechanism set at the inside of a cassette loading mechanism by adding a stopper to a cassette holder to prevent the insertion of a 2nd cassette when the cassette holder is kept at the cassette loading position. CONSTITUTION:A stopper 28 is added to a cassette holder 21 to hit a 2nd cassette and to prevent this cassette from being inserted by a fixed extent or more when the 2nd cassette different from a 1st cassette in the cassette holder is inserted into the cassette holder 21 which is kept at the cassette loading position. Thus the 2nd cassette is never inserted more than a fixed extent. As a result, the 2nd cassette can be taken out of a cassette slot and at the same time the mechanism set at the inside of a cassette loading device is protected.</p> |
