Tape drive device
 A tape drive device in which a cavity is formed in a reel hub provided for supplying or taking up a tape-shaped information recording and reproducing medium such as a magnetic tape or a film. A motor including a rotor unit and a stator unit is partly or wholly received within the cavity of the reel hub, and the rotating force generated by the rotor part of the motor is transmitted directly or through a reduction gearing to the reel hub to cause rotation of the reel hub.
