Abstract

PURPOSE:To optimize printing conditions (printing pressure) corresponding to the type of printing medium by varying the distance between the hammer tip of a hammer magnet and a platen while the excitation of the magnet is adjusted according to said distance. CONSTITUTION:A type of a type wheel 18 which is guided with a guide shaft 13 and moves horizontally with the turning of a screw 12 is pressed on a printing medium 20 on a platen 11 with a hammer of a hammer magnet 19 to print. In said printer, a type on the type wheel 18 is moved in the directions of the arrows C and D by turning a lever 22 in the direction of the arrow through a guide shaft 13 integral with an eccentric section 13a, a carrier frame 14 and the like and positioned at an appropriate distance with respect to the printing medium 20. At the same time, a selector switch 23 (23a) works to output a signal to control an exciting current of the hammer magnet 19 whereby the printing condition will be optimized.
