THERMAL PRINT HEAD AND METHOD OF REGULATING CHARACTERISTICS OF SAME

摘要

A thermal printhead is provided which includes a head substrate (11) made of an insulating material, a heating element (12) arranged along an edge of the substrate, drive ICs (13) for driving the heating element, a temperature sensor (18) mounted on the head substrate for temperature monitoring of the heating element, and a heat sink (20) attached to the head substrate. The heat sink has a first surface for attachment to the head substrate and a second surface corresponding in location to the temperature sensor. The second surface faces the head substrate but is spaced therefrom to define a heat-transfer adjusting region (22). The head substrate and the heat sink are attached together by an adhesive member having a desired heat conductivity. <IMAGE>
