<p>PROBLEM TO BE SOLVED: To provide a door mechanism capable of smoothly inserting and ejecting a cassette by a simple structure. SOLUTION: Protruded parts 9 and 10 are provided on the inner sides of the doors 1 and 2, and only at the ejecting time, these protruded parts 9 and 10 and the doors 1 and 2 are brought into contact with each other to open the doors 1 and 2 more than horizontally. Since the doors 1 and 2 are opened more than horizontally, there are no obstructions of the doors 1 and 2 to the cassette to be taken out by the user. Alternatively, the two divided doors are connected up by a spring 13, and at the time of releasing the doors 1 and 2 from the cassette, the doors are closed.</p> |
