Claims

[Scope of utility model registration request]

a core that forms part of a magnetic path with the yoke; an armature that is disposed opposite to the front end surface of the core;
A printing wire fixed to the armature,
a spring member that always applies a forward spring force to the armature; a magnet that forms a magnetic pole on the front end surface of the core for adhering the armature to overcome the spring force; and a magnet that is wound around the core and is in an energized state. and a coil that generates a magnetic flux that eliminates the adsorption force of the armature, and a rubber layer having a low elastic modulus is provided as a residual sheet on at least one of the facing surfaces of the armature and the core. Dot impact head.
