<p>PURPOSE:To use large/small cassettes on market as they are by providing a couple of right/left guide rails in parallel on a bottom plate of a cassette holder and using them as a reference of positioning. CONSTITUTION:A couple of right/left synthetic resin made guide rails 23 are screwed to the upper part of a bottom plate 22 of a cassette holder 10 by plural screws 24 while being shared to the right/left at the center of the holder 10 in right/left directions in parallel. A couple of inner side faces of both rails 23 are used as positioning reference faces 25 of large/small cassettes. In loading the small cassette into the holder 10, the small cassette is loaded between the rails 23 and the right/left outer side faces of the small cassette are regulated by the reference face 25 to apply positioning. In loading a large cassette, the guide slot at the bottom of the large cassette is loaded to the rails 23 to apply positioning. Thus, no guide slot is required to the bottom of the small cassette and large/small cassettes on market are used without modification.</p> |
