A document feeder comprising a driven endless belt having resilient fingers on a portion of its outer periphery for frictionally engaging and advancing a single document at-a-time from a supply of documents positioned on edge. As the belt is driven through a feed cycle, the fingers engage the face of the document in the stack and advance the document through a gap to a transport station. The fingers remain in contact engagement with the document only during movement of the document to the transp...

Elongated rigid leg members are pivotally connected to one another at their ends and provided with oppositely facing magnetic elements for clamping opposite sides of a sheet of paper or the like. Two center members may be hinged together at one end with an additional member pivoted to the other end of each of the two center members to permit folding about mutually perpendicular axes. The device is used primarily to clamp open large documents such as blueprints and the like that are normally stor...

A document holder including a vertically shiftable support platform, a clamping arm overlying the platform, and springs yieldably urging the platform and arm toward each other. The clamping arm is shiftable laterally of the platform. Operator mechanism engaged by the platform when it is depressed shifts the arm laterally of the platform for insertion of a document. When the platform shifts back to its raised position the arm moves back over the platform to grip the document.

A document printer for automatically printing on a check or the like preselected data on a plurality of lines. A print head is controlled to traverse the face of a document for printing thereon. The print head is controlled to exactly duplicate the path of a path defining structure for carrying out the printing operations.

The cassette of the invention comprises a plastic tray having at one end an array of projecting curved fingers and an auxiliary member having an array of curved fingers, with the auxiliary member adapted to seat on the base so that the curved fingers of the base form a smooth curve with the curved fingers of the auxiliary member. Before the auxiliary member is seated on the base, a plurality of separator sheets to be carried thereby are secured to the base by means of holes which are threaded on...

A document hopper, loader and follower assembly is provided wherein documents are automatically loaded into a feed device from a hopper by a movable follower assembly. The follower assembly is so mounted as to allow documents to be added to the hopper while the loading operation is in progress.

Apparatus for feeding documents having an adhesive area thereon. An oscillatably mounted vacuum sucker has a curved surface and a slot. A rack holds a stack of documents in operative contact with the sucker. The sucker is oscillated to separate the closest document from said stack. Take-away roller means are connected to remove said document from said sucker. A mask is mounted on the bottom of said rack to cover said slot in one position of said slot whereby said adhesive areas do not come in co...

A gripper on endless chains is actuated by a sensor to latch over the leag edge of a document, such as a paper bill, upon insertion thereof into a machine, and simultaneously a magnetic scanning head is lowered against the bill to perform a magnetic ink test. Thereafter, the chains are operated so as to transport the document along a chain run to an inspection station where it pauses for photoelectric inspection at a number of key spots, whereby validity and denomination are determined. Thereaft...

A 90.degree. reflector scans a flat document to reflect an image of part of the document into a plane parallel to the document. Then a 180.degree. reflector reflects the image back toward a detection station. A transport made of a cable and pulleys moves the 180.degree. reflector at one-half the speed of the 90.degree. reflector so that the optical distance between the detection station and the document remains constant throughout the scan.

A document feeder for transferring original documents placed in a stack one at a time in succession into a copying position on an exposure platen of a copy machine includes an endless belt having a run parallel to a surface of the platen of the copy machine. The endless belt comprises a sheet of a thin, opaque flexible material formed in a continuous loop with a plurality of parallel ridges extending longitudinally of the belt around its outer surface for frictional engagement with an original d...
