Cassette holder allowing large and small cassettes to be selectively loaded

摘要

A holder for the selected loading of a large or small cassette. A pair of positioning-restriction elements is provided inside the cassette holder at a distance enough for the small cassette to be loaded therebetween. A cassette detector detects the large cassette when it is loaded through the cassette opening. A drive mechanism moves the restriction elements from positions allowing the small cassette to be loaded to positions where the restriction elements allow the large cassette TO be loaded. A pair of flaps is positioned so that each flap is closer to the front-end section of the cassette opening than the positioning-restriction elements. The distance between the flaps allows the small cassette to be loaded therebetween. The flaps are opened so the large cassette can be loaded and they obstruct the small cassette from being loaded when at least either of the flaps is pushed by the small cassette.
