A cassette loading mechanism of a magnetic recording and reproducing apparatus is capable of selectively loading a large-sized cassette and a small-sized cassette. A large-sized cassette insertion opening having a form corresponding to the large-sized cassette (3) is provided in a cassette control unit (K1). The inserted large-sized cassette (3) is supported by a slider (6). This slider (6) is movable between an insertion position (6S) and an operation position (6P). The small-sized cassette (1) is received in a housing (19) outside the cassette control unit (K1) through the large-sized cassette insertion opening and it is set and supported in an adapter chassis (14). The adapter chassis (14) is movable through a slide plate (30) between a retreat position (14S) enabling insertion of the large-sized cassette (3) and a setting position (14G), and between the setting position (14G) and an operation position (14D). The adapter chassis (14) can be attached to the slider (6) in the operation position (6P). |
