Claims

[Scope of utility model registration request]

A permanent magnet is attached to the annular outer wall of the core part, and a magnetic coil is wound around a columnar body implanted inside the core part to constitute an electromagnet, and further, a magnetic circuit is formed in cooperation with the core part. A leaf spring with an armature fixed at the tip is attached to the armature holder to be formed using a mounting member, the armature is attracted to the columnar body by the permanent magnet, and the permanent magnet is energized by exciting the magnet coil. In a spring-release type print head of a wire dot printer, the mounting member is divided into a plurality of divided parts. The plate spring is made of a magnetic material and is screwed from the armature holder side to sandwich the leaf spring between the armature holder and the mounting member, and the mounting member is attached to the core portion. 1. A print head, wherein the mounting member is included in a part of the magnetic circuit, and the mounting member is disposed so as to be in contact with the magnetic circuit.
