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 for linear movement in a direction parallel with the drum axis. When the transceiver is operating in the receive mode, the copy medium having adhesive along at least one edge circumscribes the drum in a closed loop so as to eliminate the necessity for transmitter-receiver angular synchronizing signals which would otherwise be required for locating the copy margin adjacent the edge of the copy paper. After completion of a transmission, the copy medium is severed along a line so as to provide an appropriate margin for the copied information content. In one embodiment of the invention, the closed loop is formed from a single sheet having adhesive along one edge for purposes of forming a bond between opposite edges of the sheet when the sheet is applied to the drum. The read/write head includes a cutting wheel which is adapted to sever the sheet along the appropriate line when the head is moved in a cutting stroke along the length of the drum with the cutter wheel in contact with the sheet. In another embodiment, the copy paper includes tear strings displaced along its back surface running parallel to the axis of the drum and of sufficient number so that a tear string for shearing the copy paper loop is likely to be near the margin of the copy.
