Abstract

This mechanism consists of (a) a unit member serving the function of an eject slider/interposer, (b) an eject spring, and (c) a collet pin. Figs. 1 and 2 show the eject mechanism in the latched and unlatched positions. As the diskette is inserted (see arrow 30, Fig. 1), the front of the diskette contacts diskette stop 11 on eject slider 10. As the operator continues to insert the diskette, eject slider 10 is forced to slide backwards, as it is guided by a slot in upper plate 12. Eject spring 13 applies a force opposing this action, and the combination of forces from the diskette and the spring apply a moment on the slider that forces the front of the slider downward against the upper plate. As the slider moves toward the rear of the disk drive (i.e.

Diskette Eject Mechanism

This mechanism consists of (a) a unit member serving the function of an eject slider/interposer, (b) an eject spring, and (c) a collet pin. Figs. 1 and 2 show the eject mechanism in the latched and unlatched positions. As the diskette is inserted (see arrow 30, Fig. 1), the front of the diskette contacts diskette stop 11 on eject slider 10. As the operator continues to insert the diskette, eject slider 10 is forced to slide backwards, as it is guided by a slot in upper plate 12. Eject spring 13 applies a force opposing this action, and the combination of forces from the diskette and the spring apply a moment on the slider that forces the front of the slider downward against the upper plate. As the slider moves toward the rear of the disk drive (i.e., in the direction of arrow 30), the front leg 32 of the slider interferes with collet pin 14. This causes the leg of the slider to deflect, as shown in Fig. 1. When the operator pushes the diskette fully in, the slider's front stop 31 drops back of stop 15 on the upper plate. The eject mechanism is then in the latched position with the front leg of the slider still in the deflected position. When the operator turns handle 20, the action of cam 21 and collet load spring 22 causes collet pin 14 to drop. When the collet pin drops below the slider, the front leg 32 of the slider is free to return to an undeflected position. The leg of the slider is now in the same vertical plane as the collet pin....
