PURPOSE:To scale up the shape of the mounting section of a nose sufficiently without being limited by the form of the nose by superposing and fixing both a front yoke and a leaf spring and both the leaf spring and an armature. CONSTITUTION:An armature 30 is inserted into the slit 25 of a front yoke 24 while a leaf spring 26 and a spacer 28 are stacked to the front yoke 24. The front yoke 24, the leaf spring 26 and the spacer 26 and both the armature 30 and the leaf spring 26 are superposed and fastened through welding. A printing wire 32 is inserted into the guide holes 36 of a guide member 37, and the front yoke 24, the leaf spring 26, the spacer 28 and a nose member 33 are assembled while a rear yoke 13 is assembled so as to be oppositely faced to the armature 30. Consequently, a through-hole for electron beam welding need not be formed to the nose member 33. Accordingly, the degree of freedom of the shape of the nose member 33 is improved, thus preventing limitation on the shape of a mounting section 38. |
