。 A recess is formed in the outer circumferential surface of a printer head assembly in which a coil core support member, a permanent magnet, and a yoke member are laminated in the axial direction in order to attract the spring member supporting the wire against its elasticity when the wire is not energized, in correspondence with the coil core. At the same time, a magnetic attraction force adjustment device for a spring charge type printer head is characterized in that a magnetic member whose magnetic resistance can be adjusted and which allows magnetic flux branched from a permanent magnet to flow is positioned and fixed in the recess.
