Abstract
An exothermic type printing head is provided including a substrate, and electric conductors and exothermic elements mounted on the substrate. At least one common electric conductor is mounted on the substrate. Each common conductor has a plurality of branches extending therefrom. A corresponding plurality of discrete electrically conductive elements are also mounted on the substrate. Each of the electrically conductive elements is longitudinally arranged between a pair of branches extending from the common conductor. At least one integral exothermic element of predetermined width is mounted on the substrate overlying the discrete electrically conductive elements and branches of each common conductor. Signals are supplied to the common conductors from a common source.
Claims9
An improved exothermic printing head for thermally recording a printing character on a thermally sensitive medium comprising a substrate, a first conductor means mounted on said substrate, said first conductor means including at least one pair of commonly referenced conductors, second conductor means mounted on said substrate and including a second conductor disposed intermediate each pair of commonly referenced first conductors, and exothermic means overlying each said first pair of conductors and second conductor disposed intermediate said pair of first conductors, said exothermic means being adapted to be activated to produce a pair of dots on said thermal sensitive medium in response to said second conductor means being referenced to a potential different than the potential at which said first pairs of conductors are commonly referenced.
An improved exothermic type printing head for thermally recording a printing character on a thermally sensitive medium as claimed in claim 6, wherein said first conductor means includes at least two pairs of longitudinally arranged conductors.
