<p>PURPOSE:To prevent a cassette mounting/dismounting mechanism from being deformed by providing a bearing support means in which at least either one side of the turning shaft of a cassette presser can be moved upward and downward. CONSTITUTION:The turning shaft 6 on one side formed at the side plane of the cassette presser 3 is supported with the elongated hole of a side chassis 10, and can be moved upward and downward. In case of applying a force P in a downward direction on a cassette holder 2 in the ejecting state of the cassette 3 or in a state where the cassette 3 is inserted to the cassette holder 2 insufficiently, the turning shaft 6 is moved upward, and at this time, an elastic body 20 pressing the turning shaft 6 downward is deformed. Thereby, no large force is applied on each mechanism parts of a cassette 31 mounting/dismounting device, then, no deformation of each mechanism parts is generated.</p> |
