Abstract

Magnetic recording diskettes are fed, one at a time, from the bottom of a stack of such diskettes. Fig. 1 shows a stack of diskettes 10 which are held in an aligned, downwardly sloping, stack by wire forms 11. The two side-disposed wire forms (only one of which is shown) slidably carry a weight 12 which biases the stack toward a lower guide block 13. At this position the lowermost diskette encounters feeder finger 14, and surfaces 15 and 16 which are integral with the guide block which supports the stack of diskettes. Finger 14 is shown in detail in Figs. 2 and 3. Reciprocating movement of finger 14, to first move the lowermost diskette to a utilization position 17 (where the diskette is used by a device not shown), and to then return to the pickup position shown in Fig.

Diskette Feeder

Magnetic recording diskettes are fed, one at a time, from the bottom of a stack of such diskettes. Fig. 1 shows a stack of diskettes 10 which are held in an aligned, downwardly sloping, stack by wire forms 11. The two side-disposed wire forms (only one of which is shown) slidably carry a weight 12 which biases the stack toward a lower guide block 13. At this position the lowermost diskette encounters feeder finger 14, and surfaces 15 and 16 which are integral with the guide block which supports the stack of diskettes. Finger 14 is shown in detail in Figs. 2 and 3. Reciprocating movement of finger 14, to first move the lowermost diskette to a utilization position 17 (where the diskette is used by a device not shown), and to then return to the pickup position shown in Fig. 1, is controlled by stepper motor 18, belt 19 and idler pulley 20. The enlarged view of Fig. 2 shows the pushing surface of finger 14. This surface includes a wedge portion 21 which operates to separate the lowermost diskette 22 from the adjacent diskette 23, as the finger moves to position diskette 22 at position 17 (Fig. 1). This wedge operates to move diskette 22 forward, away from diskette 23, before sliding movement occurs between the two diskettes. When finger 14 reaches position 17, a cam (not shown) cooperates with roller 40 and forces finger 14 to the dotted line position shown in Fig. 3. The finger now returns to its Fig. 1 position. During this return movement, finger s...
