Claims

[Scope of utility model registration request]

One end of a leaf spring is welded to the bottom of the armature to which the printing wire is attached, the other end of the leaf spring is fixed to the core, and one end of the core is intersected with the bottom of the armature through a small gap. A permanent magnet is inserted into the core to attract the armature to one end of the core against the elasticity of the leaf spring, and at the time of printing, the elasticity of the front leaf spring is used to offset the attraction force. A coil for causing a printing operation to be carried out by an armature is wound around the core, and the thickness of the flexible portion at the center of the leaf spring is thinner than other parts, and a through hole is provided in the flexible portion.
