[Claims for Utility Model Registration] (1) A comb-shaped hammer spring 1 having an appropriate number of leaf spring parts each having a printing pin 2 and having different lengths provided at predetermined intervals along a printing line, and each of the leaf spring parts. A spacer 7 with a step that backs up the base of the leaf spring part in order to make the natural frequency of the leaf spring substantially uniform, a permanent magnet 5 for attraction, a back plate 6, and a spacer 7 facing the ends of each of the leaf spring parts. A comb-like pole core 3 equipped with a releasing coil 4 is provided, and the end of the plate spring portion is attracted to the pole core 3 by the attractive force of a permanent magnet 5, and by energizing the releasing coil 4, the permanent magnet 5 is attracted. In the printing hammer of the line dot impact printer, which uses the restoring force of the leaf spring part to offset the force, the line dot impact printer is characterized by changing the position of the suction surface of the pole core in accordance with the change in the position of the printing pin. Printing hammer for printers. (2) In the printing hammer, each pole core that attracts the leaf spring part is arranged on the same line, and the end is notched so that the position of the attraction surface of the pole core changes in accordance with the change in the position of the printing pin. Characteristic printing hammer for line dot impact printers.
