Claims

[Scope of utility model registration request]

an armature having a printing wire at one end and supported by a drive spring; an electromagnet provided opposite to the armature and causing the printing wire to drive printing by intermittent a magnetic field with the armature as a magnetic path; When the electromagnet is not excited, a permanent magnet that creates a magnetic field that attracts the armature to the electromagnet against the elasticity of the drive spring, and a plurality of pairs of the electromagnet and the armature are housed, and a magnetic bypass of the permanent magnet is provided. and a magnetic path part forming a magnet base having a member, the release type print head excites the electromagnet to eliminate the attraction force of the attracted armature, and drives the printing wire by the restoring force of the drive spring. The print head is characterized in that the magnetic bypass member is separated from the magnet base and has a configuration that allows its position to be adjusted.
