Abstract
A facsimile stylus assembly comprises one or more electrical conductors which are completely enshrouded by an electrically insulating sheath except for one end of the conductors which terminates in an uninsulated surface so as to form an output electrode. In one specific embodiment, the sheath comprises an electrically insulating cable having opposed flat surfaces and a plurality of spring wires which are situated within the cable. The spring wires are parallel to and insulated from the conductors. The spring wires are curved to bias the stylus assembly against the document upon which the facsimile recording is to be made.
