A cassette loading mechanism for a magnetic recording/reproducing device is disclosed, in which two different cassettes can be loaded selectively. Two inserting openings, profiled to conform to a large size cassette (3) and a small size cassette (1), are provided in a cassette control unit (K1). The large size cassette (3), when introduced, is held by a slider (6). This slider (6) is movable between a position of insertion (6S) and a position of recording and/or reproduction (6P). The small size cassette (1) inserted into the unit (K1) is held by an adapter chassis (14). This adapter chassis (14) is movable, by the medium of the loading chassis (25), between a position of insertion (14S) and a position of recording/reproduction (14Q). The adapter chassis (14) may be attached to the slider (6). A lid (28) is mounted to the unit (K1) for rotation for opening or closing the inserting opening for the large size cassette. Locking levers (34L, 34R) for engaging with the lid (28) are provided at both end edge portions of the lid (28). This locking lever (34) releases the locking of the lid (28) only when the large size cassette (3) is introduced. The lid (28) is opened only when the large size cassette (3) is introduced via the inserting opening for the large size cassette. |
