Floppy disk dive device

An electronic appliance having a floppy disk drive device for recording and reproducing information on a disk in a disk cartridge, the disk having a metal disk hub with a central hole and a drive hole partially offset from the central hole, said floppy disk drive comprising:

• a spindle mounted so as to engage the central hole of the disk;
• a spindle motor operatively coupled to said spindle, said spindle being rotatable thereof by the spindle motor;
• a rotary member fixed to said spindle and rotatable therewith;
• a chucking magnet positioned to attract the metal disk hub of the disk toward said rotary member;
• a chucking lever having first and second ends pivotally attached to said rotary member at essentially said first end;
• and
• a drive pin mounted at essentially said second end of said chucking lever and positioned for engagement by the drive hole of the disk when aligned therewith, wherein said chucking lever is movable radially towards and away from the spindle and does not include a radial biasing member independent from the chucking lever, said chucking lever being formed of an elastic material so that said chucking lever may swing within a predetermined angle by the force of said chucking magnet attracting the metal disk hub of the disk to bear bearing against said drive pin when disk chucking is not accomplished.

A computer having a floppy disk drive for recording and reproducing information on a disk in a disk cartridge, the disk having a metal disk hub with a central hole and a drive hole partially offset from the central hole, said floppy disk drive comprising:

• a spindle mounted so as to engage the central hole of the disk;
• a spindle motor operatively coupled to said spindle, said spindle being rotatable by said spindle motor;
• a rotary member fixed to said spindle and rotatable therewith;
• a chucking magnet positioned to attract the metal disk hub of the disk toward said rotary member;
• a chucking lever having at least a portion being movable radially towards and away from the spindle and not including a radial biasing member independent from the chucking lever, said chucking lever being resiliently bendable to enable the chucking lever to swing away from the rotary member within a predetermined angle;
• and
• a drive pin mounted near an end of said chucking lever and positioned for engagement by the drive hole of the disk when aligned therewith, wherein said chucking lever may swing within a predetermined angle by the metal disk hub bearing against said drive pin when disk chucking is not accomplished.
