Disclosed is a document printer of the type suitable for imprinting messages upon individual documents fed into the apparatus (e.g., bank checks). The apparatus includes an internal printing station disposed along a document feed path. The path includes a feed slot in an exterior wall of the apparatus. The printing station includes both impact printer means and document drive means, the latter operative to move the document along the document path positioning different parts of the document adja...

This invention relates to the classification of a stream of documents, such as mixed mail pieces, into size and orientation of categories for subsequent processing. The apparatus includes a laser beam which scans a conveying belt upon which the documents are placed. Appropriate circuitry is provided so that a determination may be made as to the length and width of the document being conveyed across the belt. Downstream from the belt is a segregation system in which the various sizes of documents...

A novel loose-leaf holder is provided for binding documents such as multi-leaf computer printouts and mounting the same in a suspension-filing and/or storing system. The holder is of the type described in U.S. Pat. No. 4,056,296 and comprises a plastic body which is molded as an integral unit and comprises two side sections which are connected together by a hinge section so that they can be swung toward and away from one another. The improvement comprises document mounting pins carried by one si...

A binary sorting code is read from documents and transmitted to a sorting machine where the code for each document is decoded and used to direct the document to a specific stacker. Cycling of the sorter is controlled by a sequencer responsive to timing pulses from a shaft encoder. Each sequence cycle is initiated by a flip-flop circuit responsive to a document detector. An additional flip-flop provides for fault detection in the system.

A document file is disclosed having a quick release clamping mechanism. The mechanism includes a tube of resilient and flexible plastic having a central portion anchored in the file and two end portions onto which documents with punched holes can be threaded. The mechanism includes a clamping plate also to be threaded onto the two end portions and having clamping tongues under which the free end portions of the tube can be wedged after passing through holes in the clamping plate. Each clamping t...

A method of printing wherein magnetic particles dispersed in an ink are selectively orientated prior to printing onto a document where the particles are aligned on a carrier while the ink is in a low viscous state and the printing is effected when the ink is in a high viscous state. The method by which the viscosity is changed is the selective application of heat.

In order to removably yet reliably assemble the frame parts, endless belt and sprocket of a document tractor, holes are provided in the hub of one of the frame parts which provide a guide platform for the endless belt which has pins engageable with perforations on the document to be metered. Flexible rods in registry with these holes extend from the other frame part. Latches on the outer ends of these rods engage the outsides of the holes when the rods move into latching engagement as the frame ...

A document shredder which comprises a strip cutter to cut waste document into strips, a chip cutter to cut the strips into chips, and a minuting device disposed downstream of the chip cutters to cut the chips into pulp-like mass. The minuting device includes a housing having a conical surface formed with cutting teeth, and a conical rotary body formed with cutting teeth in engagement the cutting teeth of the housing.

The negotiable document which may be used, e.g. by airlines includes a cover sheet provided with a hot spot carbon or other image transfer medium and at least one underlying sheet fully or partly coated with microcapsules of a dye intensifier and attractor. When information is imprinted on the cover sheet, the microcapsules of the dye intensifier in the underlying sheet are burst to wet the sheet and, thus, allow impregnation of the image transferred by the hot spot carbon into the fibers of the...
