STYLUS CONSTRUCTION

摘要

GASKILL, David M., Jr. D'AGOSTINO, Rudolph F. STYLUS CONSTRUCTION A stylus for the thermal recording of information on a heat sensitive recording medium which includes an electrically insulated member of low thermal conductivity which supports a pair of electrical conductor strips on the sides thereof so as to dispose such strips in opposed spaced relationship to each other. The conductor strips run along the length of the member and terminate at the lower end thereof. That end is also coated with an electrically resistive film which contacts the lower spaced ends of the conductor strips so as to form a current path therebetween. Electrical connections are attached to the upper ends of the strips for connecting the current path to a power source such that current passing through the path produces localized heat at the stylus tip.
