Patent ID: 7101440

Claim:
An ejecting apparatus comprising: a plurality of liquid drop ejecting heads, each of the heads having a plurality of nozzles aligned with a same interval therebetween for ejecting a fluid liquid material to a substance to cause reception of the ejection, the plurality of nozzles being disposed in a plurality of arrays, each nozzle array having an end-array-nozzle group and a middle-array-nozzle group; a holding member for holding the plurality of liquid drop ejecting heads for ejecting the liquid material disposed in line so as to face a surface of the substance to cause reception of the ejection having a space between the surface which has the nozzles and the surface of the substance to cause reception of the ejection; a moving member that moves at least one of the holding member or the substance to cause reception of the ejection relatively such that the liquid drop ejecting heads are moved along the surface of the substance to cause reception of the ejection; an array of the nozzles being disposed on each of the liquid drop ejecting heads and being disposed in a direction which crosses the substance to cause reception of the ejection diagonally to a direction of relative movement to the substance to cause reception of the ejection, the, plurality of liquid drop ejecting heads being disposed in a staggered manner in a plurality of arrays so that the plurality of liquid drop ejecting heads are disposed in at least two head arrays, the nozzles in the end-array-nozzle group are disposed continuously over a longitudinal length of the head with respect to a direction of each head array, portions of the liquid drop ejecting heads overlap each other in a direction of the head array, and the ejection amount of each nozzle in the end-array-nozzle group, which if not controlled would be greater than an average ejection amount per nozzle by more than 10%, is controlled to be zero: and a controller having a delineating calculating section, the delineating calculating section having: a delineating starting position calculating section; a main scanning controlling calculating section; a sub-scanning control calculating section; and a nozzle ejection control calculating section, the nozzle ejection control calculating section performing calculations so as to control the ejection of the fluid liquid material by determining which nozzle to operate.
