摘要： In the wire dot printer head of the present invention, there is provided an armature stopper against which an armature having pivoted from a printing position to a stand-by position comes into abutment, the armature stopper being formed by bonding an elastic plate and a hard plate with each other into an integral combination and thereafter punching the integral combination from the hard plate side. By this punching work the armature stopper is warped so that the hard plate side is convex in shape. With this warp, when the armature having pivoted to the stand-by position comes into abutment against the armature stopper, the armature stopper deflects in a direction to eliminate the warp. With this deflecting motion, an impact force induced upon mutual abutment of the armature and the armature stopper is diminished and deformation or chipping of the hard plate are suppressed, further, the durability of the armature stopper is improved and the printing accuracy is kept high over a long period.

摘要： The present invention is a wire dot printer head wherein a spacer is inserted between a yoke block and a head holder. The yoke block has yokes opposed to plural armatures, coils wound respectively round plural cores whose one ends are opposed to the armatures, and fulcrum portions which hold the armatures so that the armatures can rise and fall with respect to end faces of the cores. The spacer is adapted to move under the action of an external force, thereby changing the spacing between the yoke block and the head holder.

摘要： In the wire dot printer head of the present invention, an armature adapted to move pivotally between a printing position and a stand-by position is provided with a pivot shaft serving as a fulcrum, and the pivot shaft is pinched and supported by a pair of support members from both sides in the pivoting direction of the pivot shaft. In at least one support member is formed a concave support groove into which an outer periphery surface of the pivot shaft is inserted in a state of surface contact with the groove. When the armature moves pivotally in a printing operation, the surface of contact increases because the pivot shaft and the pivot groove are in surface contact with each other, thus preventing the occurrence of a local concentration of a strong force on the contact portion between the pivot shaft and the support groove. Besides, such a motion of the pivot shaft as being rubbed against the other support member is restricted by the aforesaid surface contact, whereby the wear between the pivot shaft and the other support member is also diminished. Consequently, wobbling of the pivot shaft during printing is prevented and variations in a wire tip position are also prevented, thus ensuring a high print quality.

摘要： In a wire dot printer head of the present invention, an armature is formed by coupling a magnetic circuit formation member having a supported piece with one end inserted into a cavity formed on a surface of a yoke to an arm coupled to a wire. The supported piece of the armature is rotatably supported by a support point, thereby a side surface of the cavity and a side surface of the supported piece, and a bottom surface of the cavity and an end surface of the supported piece can be set in the proximity. Accordingly, magnetic resistance between the magnetic circuit formation member and the yoke can be reduced.

摘要： In order to restrain the deterioration in assembling precision and prevent the formation of rust and deterioration in magnetic characteristics in a yoke to thereby obtain magnetic characteristics required for high-speed printing, a yoke having a core around which a coil is wound and a reference surface for assembly is made of permendur material, wherein the reference surface is polished so as to be flattened to complete the yoke. Accordingly, the reference surface of the yoke is precisely formed to be flat, thereby being capable of restraining the deterioration in assembling precision. The yoke is made of permendur material, so that the formation of rust on the yoke can be prevented. A plating layer that is a cause of magnetic resistance is not formed on the yoke, whereby the deterioration in magnetic characteristics at the yoke is prevented to thereby be capable of obtaining magnetic characteristics required for high-speed printing.
