Abstract: A film loader (16), loads a planar film sheet (58), such as a microfiche, onto a vacuum head (54) associated with an X/Y positioner (56). The film sheet is edge supported between slots (106) in two side plates (36, 38), and is transported along the path defined by these slots by driven rollers (40, 110). The vacuum head (54) is positioned at a location transversely adjacent and partially intruding into this film path. Stop pins (62) block the movement of the film sheet beyond this location so that the film sheet comes to stop with an edge (68) resting on the vacuum head. Guide pins (64) are inserted into the film path upstream of this location, and are moved downstream so as to confine the film sheet to a well defined position between the guide pins (64) and the stop pins (62). An actuator (70) forces the film sheet transversely against locator pins (66) which protrude from the vacuum head (54), thus precisely aligning the film sheet (58) onto the vacuum head (54).

Abstract: A paper feed device to forward documents to be copied across a document glass utilizing foraminous rollers positioned above the glass at a slight angle to the direction of document movement to move the side of the document into sliding relationship with a reference edge during the forwarding operation. The angle is produced by a curved drive shaft and rollers at opposite ends of the drive shaft are at different angles to the direction of paper movement. The rollers and drive train are rigidly mounted on a plate which is nonrigidly carried in a frame which pivots about a hinge at one end of the document glass. The plate rests on the top surface of front and rear reference edges when the frame is closed to assure accurate positioning of the rollers in relation to the document glass. After completing the forward feeding of a document, it is reversed a slight distance to a registration position for the copying operation.

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.
