Claims

[Claims for Utility Model Registration] Armatures 3 that hold a printing wire 4 at one end and are arranged radially; a leaf spring 5a that biases the armatures 3; a core 1 facing the armatures 3; and the core. 1, a permanent magnet 7 that attracts the armature 3 to the core 1 against the bias of the leaf spring 5a, and a permanent magnet 7 that cancels the magnetic flux of the permanent magnet 7 to release the armature 3. This is a spring-judge type printing head consisting of a coil 2 wound around the core 1, and the number of turns of each coil 2 is varied depending on the gap amount between the tip of the printing wire 4 and the cylindrical platen 10. A printing head characterized by being changed accordingly.
