摘要： According to a dot head of the invention, an armature structure for moving a printing needle forward and backward has the efficiency that the magnetic characteristics is excellent and mechanical intensity is high. The armature structure is manufactured in a manner that an arm member, which is formed by subjecting a plate-shaped material excellent in abrasion resistance performance and having a high intensity to a plating processing using born etc., is sandwiched at a portion thereof from both sides in a stacked manner by two armature members each of which is formed by subjecting a plate-shaped material excellent in magnetic characteristics to a plating processing using born etc. A pin formed by subjecting a piano wire to a plating processing using boron etc. is inserted with a small pressure into common through holes of the two armature members and the arm member thus stacked thereby to provisionally assemble them. A pair of electrodes are made in contact to the portions including the slightly-pressed-in pin near the pin of the provisionally assembled two armature members and the arm member, and a current is supplied to the electrodes in a state that the portions are sandwiched by the electrodes thereby to melt and harden the plated portions using boron etc. to integrate the two armature members and the arm member.

摘要： An armature structure according to the present invention is arranged in a manner that two armature members, in each of which a shear plane and a broken-out section are formed by a punching processing on an inner periphery of a through hole into which a fulcrum shaft fits, are joined integrally in a state of sandwiching an arm therebetween so as to position the broken-out sections of the armature members at the outer side. Thus, even by the rotation of the armature structure during a printing operation, there does not arise a problem that the armature structure inclines due to eccentric wear, so that a stable printing state can be obtained for a long term.

摘要： A print head for a dot printer of the present invention includes a plurality of armatures which support a print wire on one end. A back stopper is provided on the rear side of the armatures to stop the armature as the print wire retreats after a print strike. The back stopper is provided with openings so that when an armature strikes the back stopper, upon withdrawal from the print strike, the noise emanated from the back stopper is reduced. A sound dampening piece may be abutted to the rear of the back stopper to further reduce the noise.
