Abstract

PURPOSE:To eliminate the need for an adjustment margin between supporters and to improve an arrangement density of nozzles, by a method wherein a horizontal divergency in the injection direction of ink drop is adjusted by spinning a head attached at a supporter and a vertical devergency by rotating the supporter. CONSTITUTION:In the case of ink drop being intected through a nozzle 1 toward a point (a) outside a tolerance range A of a reference point O, a head 4 is spinned around an axis thereof by unscrewing a screw 8, and with this the injection direction is moved from the point (a) to the junctions b and b' of a trace B and a vertical line Y to adjust the vertical divergency. The head 4 can be easily rotated with a jig inserted into holes 4a made in the circumference of the drum thereof. The supporter 7 and the head 4 are then revolved vertically centering aroung a pin 9a by adjusting a screwing depth of an adjustment screw 12, and with this the injection direction of the ink drop is vertically moved from the intersection points b and b' to the reference point 0.
