ABSTRACT:
A wire dot matrix print head suitable for a low cost computer printer is described. The print head incorporates a one piece armature constructed of thin high strength sheet metal. The armature has a plurality of rigid radial arms radiating inwardly from a torsionally flexible periphery. Each of the rigid radial arms has an integral pair of flanges for adding rigidity, and an attached moving core of magnetically permeable material. Each of the rigid radial arms is connected to the periphery at an arm base. Each of the rigid radial arm bases is provided with a slight bend. The combination of torsional action of the flexible periphery acting at the bend and a fixed clamping action of a cap at intermediate portion of the flexible periphery provides a biasing force to each of the radial arms.
