  • Facsimile transceiving apparatus
    Patent number: 3990694
    Abstract: A facsimile transceiver apparatus is described which includes means for advancing a document to a station at which location the document is line scanned by a laser light beam. A video signal thus formed is transmitted to a remote facsimile apparatus for reproduction of the document. The transceiver further includes an electrostatographic printing station at which station a latent electrostatic image is formed by line scanning a laser light beam over a uniformly charged photoreceptor surface. A means for line scanning at the document scanning station and at the photoreceptor surface includes a laser light source and means for alternatively sweeping the laser light beam across the document at the scanning station or across a charged image retention surface at the printing station. Means are also described for enhancing document feed, resolution, and speed of reproduction.
