Abstract
A wire-dot printing head has a housing in which a plurality of actuator assemblies are accommodated to drive a plurality of wire elements. An annular hollow space is formed in a side wall of the housing surrounding the actuator assemblies, whereby noise and vibration produced during operation of the actuator assemblies can be effectively damped due to the formation of the annular hollow space. When an interior of the housing is partially charged with gel-like damping material for damping the noise and vibration, a hollow space is formed in the charged damping material, whereby the increase in the inertial mass of the printing head can be reduced.
