<p>PURPOSE:To prevent the damage of a tape or the like for loading/unloading operation of standard and small-sized cassettes by providing a first door for standard cassette and a second door for small-sized cassette in a cassette insertion hole and providing lock members in both ends of the first door and turning both doors at the time of inserting a standard cassette and turning only the second door at the time of inserting a small-sized cassette. CONSTITUTION:When a cassette is not inserted, both end parts in the breadth wise direction of a first door 210 are locked by lock members 241 to stop turning of the first door 210, and a second door 220 can be always turned to the first door 210. When the standard cassette is inserted, taper parts 245 of both lock members 241 in the breadthwise direction are pressed by the inserted standard cassette to release lock of the first door 210 by both lock members 241; and when the small-sized cassette is inserted, the second turnable door 220 is pressed, and the cassette is inserted while being guided by a notched part of the first lock door. Consequently, not only the standard cassette but also the small-sized cassette can be inserted to a regular position and is set to a prescribed load position in a holder 300. Thus, the damage of a tape or the like for loading/unloading operation of standard and small-sized cassettes is prevented.</p> |
