PURPOSE:To attain small size and light weight by delivering a motor torque driving a magnetic disc to the drive shaft of other magnetic disc via a power transmission means so as to use one motor and drive the other magnetic disc. CONSTITUTION:When an electric power is turned on, a current flows to a coil 65, a rotor 58 is driven via a magnet 59 and a motor shaft 51 is driven via a disc 57 fixed to the rotor 58. The other motor shaft 50 is driven via a belt 62 belted to rotors 58 and 62. A cassette is loaded to both cassette guides 67 in this state. The center boss of the magnetic disc is fitted to the motor shaft 50, adsorbed with a magnetic force with a cup-shaped member 51 and the magnetic disc is driven. Thus, one motor comprised of the rotor 58 and the coil 65 drives two discs. |
