Abstract

A pivot link assembly for a finger which separates the remainder of original documents in a recirculating document feed from those documents which have been fed and returned. The pivot link is arranged so that upon completion of feeding of the original stack, the link withdraws the finger from the stack area and places it at the opposite side of the new stack of fed and returned documents.

Recirculating Feed Stack Position Indicator

A pivot link assembly for a finger which separates the remainder of original documents in a recirculating document feed from those documents which have been fed and returned. The pivot link is arranged so that upon completion of feeding of the original stack, the link withdraws the finger from the stack area and places it at the opposite side of the new stack of fed and returned documents.

In Fig. 1, an original stack of documents 10, from document 1 to document N is placed in a feeder having a plate 11. A finger 12 is under the stack. The finger is attached to pivot link 14 by pivot 15 and supported and urged upwardly by tension spring 16. The pivot link is mounted on pivot 17 and can be rotated about pivot 17 by arm 18 of solenoid 19.

In Fig. 2, a number of documents 20 have been fed from the top of original stack 10 and have been returned to the feeder below finger 12 which has been urged upwardly by spring 16.

In Fig. 3, all of the sheets from original stack 10 have been fed and returned as stack 21. With no sheets to hold finger 12 down, it is moved upward by spring 16 into contact with sensor 22.

In Fig. 4, the sensor 22 has initiated operation of solenoid 19 to retract arm 18 and pivot the pivot link 14 about pivot 17. This withdraws finger 12 from the feeder and compresses the spring, thereby forcing the finger to the bottom of the feeder. Subsequent release of the solenoid returns the pivot link to the position...
