Claims

[Claims for Utility Model Registration] A yoke member 1 consisting of an inner yoke 1b and an outer yoke 1c arranged annularly along the outer periphery of the inner yoke 1b; an armature holding member 3 for holding a plurality of armatures 4 arranged radially around the center; an elastic body 5 for urging each armature 4; and a plurality of prints driven by each armature 4. In a print head configured by stacking and fixing a front frame 6 having a guide portion 6d for slidingly guiding a wire 7, the armature holding member 3 is formed by an annular outer peripheral portion 3a,
An intermediate portion 3b extends from the outer peripheral portion 3a to the center through between the armatures 4, and a bridge that extends to bridge the center side end of the intermediate portion 3b and is fitable to the end of the inner yoke 1b. 3C, and the bridge part 3C is used as a swinging fulcrum 3d of the armature 4.
