PURPOSE:To obtain a titled printing head, wherein an auxiliary yoke is provided between neighboring printing mechanisms, an armature is not subjected to the effect of the magnetic flux of the neighboring printing mechanism, and stable high speed operation can be implemented. CONSTITUTION:The auxiliary yoke 34 is arranged between the neighboring printing mechanism. A loop (a), which is generated by a permanent magnet 28 of each printing mechanism, does not pass the armature 29 of the neighboring printing mechanism. An independent loop can be maintained by the auxiliary yoke 34. Even though the magnetic flux of the core 25 of cirtain printing mechanism is changed, the constant magnetic flux can be maintained all the time. |
