Abstract
A cassette loading/unloading apparatus enables a magnetic recording and reproducing device to be used with both a standard-type tape cassette and a miniature tape cassette without a cassette adapter. When the miniature tape cassette is used, a holding mechanism for the standard-type tape cassette is located at a position where it does not hinder the loading of the miniature tape cassette. When the standard-type tape cassette is used, a holding mechanism for holding the miniature tape cassette is located at a position where it does not hinder the loading of the standard-type tape cassette. Further, only one tape extraction mechanism and only one detection unit for detecting an anti-erasure claw are provided for extracting a magnetic tape from either of the standard type tape cassette and the miniature-tape cassette and for detecting the presence of the anti-erasure claw of either of the two types of tape cassettes.
