とするドツトインパクトヘツド。 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 residual sheet provided on at least one of the facing surfaces of the armature and the core, and a base material made of a synthetic resin film and What is claimed is: 1. A dot impact head comprising a rubber layer having a low elastic modulus attached to at least the surface side.
