Claims

[Scope of utility model registration request]

A plunger hammer, which is always given a tendency to move backwards, is pressed against a stopper to position it, and when a signal is sent to a drive coil arranged around the outer periphery of the plunger hammer, the plunger hammer changes to the above-mentioned movement habit due to magnetic action. An impact printer that moves forward against resistance and strikes type to print on paper on a platen, characterized in that the stopper is movable in the front-back direction and the position of the plunger hammer is adjustable. Printer impression variable mechanism.
