Abstract

PURPOSE:To prevent increase in the variation of the stroke of an armature by tightly fixing on the attractint surface of a yoke a supporting member on which a reference surface is formed to determine the position of a stopper adapted to contact the armature. CONSTITUTION:Upon the excitation of a solenoid coil 2, an armature 7 turns fulcruming the circumference of the attracting surface of a yoke 1 to slide a needle 4 to print out, while with the return of the armature 7 by a spring 16, the needle 4 is put back by a spring 3. A supporting member 18 is tightly fixed on the attracting surface 6 with a reference surface 22 thereof pressing against the flat surface 23 an auxiliary member 24 while a stopper 20 is grasped between the extended surface of the flat surface 23 of the auxiliary member 24 and the armature so that one end thereof coincides with the reference surface. Therefore, the stroke of the armature is determined by the dimension obtained from the subtraction of the thickness of the stopper 20 and the armature 7 from a space between the attraction surface 6 and the reference surface 22. This enables accurate determination on the stroke of the armature 7.
