Abstract

PURPOSE:To make a nozzle displacement caused by the warp of a pole screw smaller than the warp of the pole screw and thereby prevent deterioration of printing quality by shortening a distance from a reference guide member to a nozzle as compared to a distance between the reference guide member and the pole screw. CONSTITUTION:A reference guide member 8 is arranged in parallel with the rotational shaft of a drum 3 and contacts a pole bearing 11 without vibration. An auxiliary guide member 9 is approx. 0.4mm clear from the pole bearing 11 fixed on a head base 7, and arranged in parallel with a pole screw 10. Nozzles 6 are radially arranged on the head base 7. It is so constituted that a distance gammaA between a reference guide member 8 to the nozzle may by approx. 1/2 of a distance gammaB between the reference guide member 8 and the pole screw 10. Therefore, if any displacement generated in the pole screw fitting part of a printing head 20, even the maximum nozzle displacement approx. 25mum or a value equivalent to almost 1/6 of the usual displacement value. Consequently a displacement value in the deflection height of ink droplets is reduced to approx. 3mum, thus significantly improving a printing quality.
