摘要： An improved print head for a dot matrix printer is provided. The printing is performed by wires projecting from said print head. The movement of the wires is controlled by the movement of armatures which contact an armature base. The construction of the base from a liquid crystal polymer or an aromatic series polyester resin results in improved vibration damping which in turn results in quieter printer operation.

The printing head includes an annular base which is provided with, at the outer portion thereof, a hammer mounting portion for securing a plurality of hammer base portions, at the inner portion thereof, a plurality of implanted columnar cores around which respective coils are wound, and a short-circuiting portion which constitutes the closed magnetic circuits of the respective coils in cooperation with respective hammers. The permanent magnet is attached to the outside of the short-circuiting portion and the hammer mounting portions at the outer periphery of the base. The printing head is sub-assembled before the attachment of the permanent magnet.
