PURPOSE:To confirm the relational dimension of an armature from the drilled opening part of a head body and to make the engaging operation of a printing element group and the armature easy and certain, by drilling the head body from a part of said head on the peripheral side thereof until reaching a center hole to form an opening part and inserting the printing element group in the head body from the aforementioned drilled opening part and engaging the leading end part of each armature with each engaging piece of each printing element. CONSTITUTION:An armature guide 1 and a yoke 2 are integrally adhered and an opening part 7 is formed to both of them toward center holes 6, 6 from the upper surfaces thereof. The relational position of armatures 4, 4... and magnets 3, 3... preliminarily incorporated in a head body can be easily confirmed from the drilled opening part of the head body. A printing element group 10 is inserted in the head body from the drilled opening part 7. Each of the leading end parts 4a, 4a... of the armatures 4, 4... preliminarily incorporated is provided to the center part of the head body in a protruded state and each of the engaging pieces 5a, 5a... of printing elements 5, 5... is brought into engagement with the corresponding leading end part of each of the armatures. |
