ABSTRACT:
The print head has armatures each provided with a holding part connected to one end of a spring plate. For avoiding concentration of a tensile stress on a brazed part between the holding part and the spring plate, part of the holding part extending contiguously to one side of the spring plate, subjected to a compressive stress when the spring is bent, is longer than the part of the holding part extending contiguously to the other side of the spring plate subjected to a tensile stress when the spring plate is bent.
