Claims

[Scope of utility model registration request]

A vibration damping device consisting of a printing hammer rotatably held by a cylindrical hammer pin, a coil spring that presses one end of the printing hammer via a cylindrical plunger, and an elastic body that locks the other end of the printing hammer. It consists of a stopper for the material, a coil that drives the printing hammer by attracting one end of the printing hammer, and a hammer support to which these are attached. In a hammer module of a printing device that press-fits and holds a convex part of a stopper having a protrusion arranged in a U groove of a hammer support,
A line printer printing mechanism characterized in that a recess is provided at the base of the projection of the stopper.
