Abstract
A magnetic tape drive device includes coils wound about a stator core secured to a base board; a rotor case containing a drive magnet secured to the inner surface thereof, the drive magnet being disposed facing the stator core; and a drive member for transmitting the rotation of rotor case to a roller, the drive member positioned on an outer peripheral surface of the rotor case.
Claims8
A drive device for driving a capstan roller for conveying a magnetic tape, comprising:
- a base;
- a stator core secured to said base and having coils wound therearound;
- a rotor case including a drive magnet secured to the inner surface of said rotor case, the drive magnet being disposed facing the stator core, said rotor case being rotatable with respect to said base when said coils are energized;
- and
- a drive member for transmitting the rotation of said rotor case to the capstan roller, the drive member being positioned on an outer peripheral surface of said rotor case.

A tape drive device for driving a capstan roller for conveying a magnetic tape, comprising:
- a base;
- a stator core secured to said base and having coils wound therearound;
- a rotor case rotatably supported with respect to said base and substantially circumscribing said stator core, said rotor case including a drive magnet secured to an inner surface thereof facing said stator core, said rotor case being rotatable in response to energization of said coils, wherein an outer surface of said rotor case frictionally contacts the capstan roller so as to drive the capstan roller.
