Combined Stop and Diskette Seating Mechanism

Diskettes are manually inserted into a drive unit, and after insertion a cover is closed to capture the diskette. If the diskette is not fully seated in the unit, any attempt to close the cover will damage the diskette.

Seating arm 10 (Fig. 1) lies in a horizontal position and prevents cover 15 from being pivoted to a closed position until diskette 20 is fully seated within drive unit 30. As diskette 20 is manually inserted into unit 30 it engages a pivotally mounted lever 11 and causes it to pivot counterclockwise. A link 12 is connected to lever 11 and to a crank 13. Crank 13 is mounted on a shaft 14 which also carries arm 10. Thus, as lever 11 pivots, crank 13 is also caused to pivot and thereby rotate arm 10 from the horizontal position toward a vertical position (Fig.
2). A torsion spring 16 (Figs. 3a and 3b), connected to arm 10, snaps arm 10 into the vertical position to fully seat diskette 20 in drive unit 30, as spring 16 passes over the center of mounting pin 17 during the rotation of arm 10.

With arm 10 in the vertical position and diskette 20 fully seated within drive unit 30, cover 15 is free to be pivoted to the close position, as shown in Fig. 2.
