Claims

[Scope of utility model registration request]

(1) In a wire dot head that biases a leaf spring using a permanent magnet, and cancels the magnetic field of the permanent magnet by excitation of a magnet coil to release the biased leaf spring and drive the printing wire, the printing wire is placed at the tip of the wire dot head. The number of elements consisting of an armature supported by an armature and a plate spring whose one end is connected to the rear end of the armature and which supports the armature are arranged centripetally on the same surface of the spacer yoke in equal numbers to the number of printing wires. Features a wire dot head.

(2) The wire dot head according to claim 1, which has a welding recessed hole near the other end of the leaf spring.
