Exothermic printing head

摘要

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.
