ABSTRACT:
A high torsional stiffness, low axial, angular and radial deflection stiffness tape drive coupling apparatus is used for driving a cassette reel with a drive motor. The apparatus includes a base which is attached to the drive motor, a compression spring disposed against the base, and a flexure member positioned adjacent the base. The flexure member includes a plurality of orthogonally extending flexible arms, at least two of the arms having a distal end connected with the base. A driver is engageable with the cassette reel and is connected with at least two of the flexible arms. An apparatus is provided for limiting axial separation of the base and driver while allowing radial and angular misalignment therebetween. Accordingly, the driver is movable axially and angularly with respect to the base by compression of the spring between the driver and base. The driver is movable radially with respect to the drive axis by flexion of at least two of the plurality of flexible arms. The driver is relatively torsionally rigid with respect to the base to facilitate rotational driving engagement of the cassette reel when there exists axial, radial, or angular misalignment between the driver and cassette reel.
