Claims

[Scope of utility model registration request]

One end of the magnetic path forming core around which the coil is wound, facing the attraction surface, is an attraction surface, and the other end is provided with a spacer that provides a predetermined gap between the attraction surface and the attraction surface of the core, and the other end is attached to the spacer. There is an armature that serves as a deformation fulcrum to be held, and the suction surface moves the predetermined distance and comes into close contact with the suction surface of the core, causing deformation along the entire length from the deformation fulcrum position to the suction surface, and the coil In a print head of a release type printer that prints by energizing a printing wire provided at the tip of the armature with a deformation recovery force released from attraction when energized, the armature holding surface of the spacer is notched. Printing characterized in that it has a structure in which a stepped portion is formed within the predetermined gap, and the front side of the stepped portion is extended toward the core and has a length extending into the armature deformed shape position. head.
