and an electromagnet 13 having a coil 12 and a leaf spring 1
The armature 15 is supported by the armature 4, a wire 16 connected to the armature, and a wire guide 17.When not printing, the armature 15 is attracted to the iron core 10 by the attractive force of the permanent magnet 11.
During printing, the attractive force of the permanent magnet 11 is canceled by energizing the coil 12, the armature 15 is released, and printing is performed using the wire 16. The relationship with the attraction force is that when the armature 15 is in the printing position, the permanent magnet 11 is larger, and the armature 15 is larger.
The open type print head is characterized in that the two stroke force curves are set to be equal when they are close to the iron core 10 and at a certain distance, and their stroke force curves intersect at that point.
