Abstract

The mechanism shown is an automatic document feeding device for a copy machine. It is made up of the following elements: a rotary file 1 for the original documents, bins 3 in the file 1 to hold the documents, sheet picking roller 4, separator-restraint rollers 5, feed rollers 6, deflector gate 7, document glass 8 on a copier, document belt feed 9, return document paths 10 and 11, and feed forward path 12.

Recirculating Original Document Feed for Copier

The mechanism shown is an automatic document feeding device for a copy machine. It is made up of the following elements: a rotary file 1 for the original documents, bins 3 in the file 1 to hold the documents, sheet picking roller 4, separator-restraint rollers 5, feed rollers 6, deflector gate 7, document glass 8 on a copier, document belt feed 9, return document paths 10 and 11, and feed forward path 12.

Rotary file 1 is made up of multiple bins 3. The bins are grouped in pairs A and B. Each of the pairs will handle a copying job to be performed by the copying machine. For example, job No. 1 is loaded in the rotary file 1 by placing all of the originals sequentially into the A bin of job No. 1. Likewise, jobs No. 2 and No. 3 have their original documents sequentially placed face down in the A bins assigned to these jobs. Each job has an A and B bin.

After the pertinent control information for all jobs has been entered into the copier, bin A of job No. 1 is automatically rotated to the proper feed position. Picking roll 4 than drops under bin A to feed the pages sequentially out of bin A. Separator restraint rollers 5 insure that only one document at a time feeds forward on path 12 to the document glass 8. Documents are transported to the document glass area by feed roller 6. When documents are being fed onto the glass 8 the deflector gate 7 aligns with the forward feed path 12. Belt feeder 9 than carries the document onto the document glass 8 where it is copied.

After the proper number of copies have been made, belt feeder 9 returns the document back through the gate 7. At this time gate 7 is deflected to sen...
