Abstract

PURPOSE: To prevent deterioration of a printing quality due to loosening of a bullet and to enable an improved printing, by a method wherein, in a free flight type printing hammer, the bullet id formed as a magnetic substance, and a magnet system is mounted at a bullet guide member.
CONSTITUTION: A hammer arm 7 hits on a rear end of a bullet 4 resulting from the derive of a printing drive device, and as a result, the bullet 4 guided by means of a bullet guide member 5 against the action of a return spring 8 strikes on a wheel type 2. The bullet 4 is, thereupon, pulled to one side by means of a permanent magnet 9 located at the inside of the bullet guide member 5, and thereby it is prevented from loosening at the inside of a guide hole and moves straight on. Restoring of the bullet 4 is performed by means of a spring 8, and the utilization of a suction force of the magnet 9 also permits the restoring of the bullet 4.
