Abstract

PURPOSE:To obtain a printing head which is easily assembled whose electromagnetic devices are positively operated, in assembling the printing head for a dot printer, by utilizing an attracting force of a magnet and a force imparting action of an elastomer in assembling and fixing said head without using a bolt, a nut or the like. CONSTITUTION:A permanent magnet 14, an armature support member 15 and a magnetic ring 16 preliminarily arranged on a rail-like assembling jig 31 are attracted by a magnetic force of said permanent magnet 14 to assemble an armature driving assemblage 20. Subsequently, a lid body 21 to which a nose member 24 is fixed by a pin 23 is arranged in front of a surface thereof and a joint member 26 is inlaid from its rear side to press an elastic tongue segment 27 to a rear surface of the magnetic ring 6. Then, the joint member 26 and an outer periphery of the lid body 21 are fixed by welding. In this case, by a force imparting action of the elastic tongue segment 27, the armature driving assemblage 20 is pressed to the lid body 21 to be firmly assembled thereto. Because a bolt or the like is not used in this assemblage, there exists no adverse affect to magnetic flux of the permanent magnet 14.
