  • Patent number: 4909648
    Abstract: A multi-format document printer and processor has a plurality of data writing and reading means for data in different formats, disposed along a transport path. Forms are separated from a continuous perforated form supply and advanced along the transport path. Bidirectional drive rollers disposed along the path advance the documents and reverse them for reprocessing as necessary. At the end of the transport path, the documents are routed to an exit hopper or a reject hopper and a sensor at the exit detects already-issued forms manually loaded by an operator, which already-issued forms can be likewise bidirectionally processed for reading, verification, modification and the like. The processor is preferably embodied for transportation tickets and boarding passes, having: optical character recognition (OCR) write and read devices, magnetic strip write and read devices and a dot matrix printer having an array of print heads operable to print a document in one pass.
    Type: Grant

  • Patent number: 4461465
    Abstract: A facsimile apparatus with a sheet feeding capability to supply sheets of documents and/or copy paper to a rotatable scanning drum. Rollers advance these sheets on a sheet-by-sheet basis along the transport path which includes a plurality of sensors. The drum is positioned so as to receive the sheets prior to scanning and subsequently repositioned after scanning so as to permit these sheets to be removed from the drum.
