A document coder for selectively removing teeth projecting from the bottom edge of a card, thereby encoding the card, including an elongated horizontally disposed block having a slot in its upper surface for receiving and guiding the tooth-bearing edge of a card to be coded, and having a plurality of transverse horizontally disposed bores which communicate with both the exterior of the block and the card edge guide slot. Also included are a plurality of punch and die assemblies. Each assembly ha...

A device is disclosed for restraining the pages of a document. The device consists of a flat, horizontal base with a vertical member mounted at one side which projects upward and has disposed at its upper end an arm which extends out over the center of the base. Attached pivotally at about the end of the arm is a downward projecting rod-like member which swings in the plane of the arm but is restrained in its swing by elastic means mounted between the downward projecting member and the horizonta...

An image reading apparatus which reads book-like documents placed on a document platen in a face upward condition. A first detector detects the height of the document surface by the shape of a side surface of the document, and a second detector detects the height of the document by the shape of the document surface. A discrimination device detects abnormal height data detected by the detectors, and distortion of image data output from an imaging device is corrected using height data determined t...

A lead screw is provided to move two or more document scanning elements at separate and differing rates of speed. In a preferred embodiment the lead screw consists of two threaded segments, each segment having a length and pitch which provides a 2:1 ratio of travel to a scan element threadingly engaged therein.

Vacuum-operated document picking and transporting apparatus includes a moving belt formed with two rows of apertures therein extending in the length direction of the belt either row of which may be coupled to a vacuum source. Apertures in one row may be located at different positions than those in the other and the apertures in one row may be spaced apart different distances than those in the other. Then as a portion of the belt containing an aperture passes between a stack of documents and the ...

A document feeder having multiple feed members biased into contact with a document to be fed which members are mounted in a manner affording their independent angular adjustment with respect to each other and with respect to the document path, and affording an equalization of the total bias force exerted against the document amongst each of the feed members.

A Touch-tone coded credit card employing first and second code groups, the first group having four bit positions and the second group three bit positions, one of which is utilized in each group to identify a decimal digit. The card is provided with a non-coded area (used for a magnetic or signature stripe) which is positioned opposite the first code group, and is at least as wide. If the card is reversed side-to-side when positioned in a code reader, no output is derived from the first code grou...

A document comprising a sheet of material having a plurality of rectangular areas adapted to be written on and defined by lines and two triangular shaped non-mark areas formed in each of the rectangular areas, the triangular areas positioned within this area so that their apices generally point towards each other and spaced apart from each other by a land area within said rectangular areas.

A document feeder includes a rotating head for moving individual documents from a stack of documents to document receiving rollers. Four vacuum ports are formed in the head at spaced points about its periphery. The ports are connected to apertures positioned in a circle on the bottom of the head. A duct extends from a vacuum source to a point adjacent the circle. As the head rotates, the apertures cooperate with the duct to connect each port to the vacuum source during the movement of the port b...

A generally rectangular document holder comprising a pair of flexible film-like transparent sheets fixed along opposite sides to a pair of elongated magnetic strips. The document holder will receive and retain a document such as an automobile registration to permit displaying the document in a suitable location within the automobile.
