Abstract

A plurality of freely rotatable plastic disks are located under a combing wheel sheet feeder and operate to aid in feeding of the last few sheets of a stack of sheets. The placement of the disks relative to the combing wheel's zone of contact operates to control the direction of sheet feeding.

Disk Type Bottom of the Bin Pad

A plurality of freely rotatable plastic disks are located under a combing wheel sheet feeder and operate to aid in feeding of the last few sheets of a stack of sheets. The placement of the disks relative to the combing wheel's zone of contact operates to control the direction of sheet feeding.

U.S. Patent 4,089,516 describes a cut-sheet xerographic copier having a resilient combing wheel paper feeder, wherein the paper bins include a resilient bottom of the bin pad which operates to simulate a continuing stack of paper, when in fact the combing wheel is feeding the last twenty or less sheets of the stack. Fig. 1 shows such a pad 10 and combing wheel 11.

Fig. 2 shows three flat, resilient plastic disks 12-14 which are mounted to the bottom 15 of the paper bin. These disks are free to rotate about axis 16. The disks lie one on top of the other, and bottom disk 14 lies on top of pad 10. Fig. 2 shows them spaced only for purposes of clarity.

Fig. 3 is a top view of the disks. Dotted lines 17 and 18 divide the disks into four quadrants, labeled A, B, C and D. The intersection of lines 17 and 18 is the axis of rotation 16. The underlying pad is shown by dotted outline 10, and the combing wheel's zone of contact to the sheets within the bin is shown as dotted outline 19. By moving disk axis of rotation 16 relative 19, the direction of paper feeding, of at least the last few sheets of the stack, can be controlled.

In all disk quadrants A-D...
