An automatic document handler employing a bottom vacuum sheet separator in conjunction with an air knife, a single blower with a cyclically operated air valve being utilized to provide sub-atmospheric air for the separator and pressurized air for the air knife to provide enhanced feeder performance and automatically compensate for variable paper weights.

An optical character reader for conversion of information to a machine readable code from a strip of alpha-numeric characters on the face of a document. It includes an elongated document slot along which the document may be hand guided through a predetermined path. Optical viewing means is provided across a scan line intersecting the path of the alpha-numeric characters. A character scanning assembly electronically generates images of each character. Recognition processing means encodes these im...

A document feed mechanism for feeding original documents to a copier imaging station. A bottom feed shingler wheel generates a shingled stack of original documents in a tray having a crowned shape, the tray crest being located forward of the shingler wheel. The shingled stack is supplied to a nip formed by an intermittently operated feed roll and a restraint roll which is rearwardly biased via a magnetic hysteresis slip clutch. The normal force on a sheet in the nip and the rearward bias force o...

Two sheet elements are secured together along selected lines to form a pocket to adaptable to receive a document for machine processing.

A document carrier is described comprising a flat sheet of unfilled parchment having one side thereof coated with a cohesive material. The opposite side of the sheet is printed along at least one edge thereof with a filler material. An erroneously encoded magnetic ink character recognition document, or other document such as an erroneously encoded check, to be machine processed is positioned on the cohesive side of the translucent sheet and the latter is subsequently folded over the document wit...

A document imprinter, especially for labels, tickets, tags, and the like, having an elastomeric platen with an outermost thin sleeve which is harder than the underlying platen material thereby resulting in sharper printing. The sleeve is preferably of a material which is smooth and glossy and non-adherent to adhesives, thus minimizing undesired transfer to the platen of adhesive from the web to be imprinted.

A document inverter is disclosed which may be utilized in conjunction with a belt conveyor wherein the document is conveyed along a continuous path before and after being inverted. Means is provided for selectively determining whether the document should be inverted or allowed to continue along the path uninterrupted.

A document carrier is described comprising a flat sheet of unfilled parchment having one side thereof coated with a cohesive material. The opposite side of the sheet is printed along at least one edge thereof with a filler material. An erroneously encoded magnetic ink character recognition document, or other document such as a multilated check, to be machine processed is positioned on the cohesive side of the translucent sheet and the latter is subsequently folded over the document with the cohe...

A document holder for use with identification card imprinters for holding a card carrying an embossed message and the document to be imprinted with the message in a fixed, predetermined relationship so that the message is imprinted at a predetermined location on the document. The document holder is dimensioned to fit standard embossed card imprinters.

An apparatus for the registration of documents on the platen of a photocopier is disclosed. The apparatus is in the form of a registration edge against which an edge of a document may be positioned. The registration edge is formed by a generally channel-shaped member of resilient material extending along an edge of the platen and fitted over the platen edge with the sides thereof gripping the opposite faces of the platen.
