Abstract
Abstract A facsimile transceiver comprising a document/copy receiving drum, a motor for rotation of the drum about the drum axis and a read/write head mounted on a rotating shaft for linear movement in a direction parallel with the drum axis. When the transceiver is operating in the transmitting mode, the information of the original document is scanned by a reading fiber optic carried on the read/write head. Illumination of the document is provided by a light pipe or a plurality of fiber optics which substantially surround the reading fiber optic which extends from the base of a recess in an arcuate surface of the read/write head which rides on the document carried by the drum. The arcuate surface has a portion with a radius of curvature substantially equal to the radius of curvature of the drum in the vicinity of the reading fiber optic and portions spaced from the reading fiber optic with radii of curvature substantially larger so as to prevent undesirable bouncing of the head as a discontinuity in document thickness passes between the read/write head and the drum.
