PURPOSE:To improve the operability of a magnetic recording and reproducing device, by incorporating an adaptor for small-sized tape cassette and providing a moving means for mounting the adaptor on the device and another moving means which mounts a standard type tape cassette. CONSTITUTION:When a standard type tape cassette 25 is inserted into a device 1 from an inserting port 3 and a standard type tape cassette holder 8 is pressed, a sliding arm 21 turns counterclockwise around a shaft 24 and the tape cassette 25 is loaded into the device 1. When a small-sized tape cassette is loaded into the device 1 another sliding arm 15 is turned clockwise around a shaft 18 after the standard type tape cassette 25 is taken out and an adaptor holder 6 and part of an adaptor 7 are projected from an entrance 4. When the small-sized tape cassette is mounted on the adaptor 7 and the arm 15 is turned counterclockwise around the shaft 18 thereafter, the holder 6 and adaptor 7 are guided to the positions shown by the broken line through the positions shown by the alternate long and two short dashes line and the cassette is loaded into the device 1.
