Claims

[Scope of utility model registration request]

In the dot printer head where the printing wire is driven under the control of an electromagnet and performs printing, the printing wire is attracted by a plurality of electromagnets arranged on the substrate at intervals in the circumferential direction around the axis of the dot printer head, and the printing wire is attracted by the electromagnets. A flexible armature is mounted on the substrate surrounded by electromagnets so as to cover the coil lead-out part of the board and the coil lead-out wire of the electromagnet coil introduced into the coil lead-out part. A dot printer head characterized in that it is filled with a fixing member that is flexible and resistant to high and low temperatures, and an adhesive layer is formed so as to penetrate between the yoke of the electromagnet and the winding portion of the coil.
