ABSTRACT:
In a copier, an original document feed moves two originals to be copied simultaneously onto a document glass. The document glass is 11 inches by 17 inches and accommodates two 81/2 by 11 inch documents side-by-side. The dual document feed is loaded sequentially with two originals and registers the two originals side-by-side to right and left corner references at an entry station. The entry station includes aligning rollers whereby the operator need only position the originals close to the correct position. The aligning rollers then corner-register the documents side-by-side. After the originals have been registered side-by-side in the entry station, they are automatically fed forward substantially simultaneously to be registered side-by-side on the document glass. Electronic control circuits are shown whereby the dual document feed apparatus may be controlled to feed either single or dual original documents.
