ABSTRACT:
A line-type liquid ejecting head includes an ejection unit group constituted by a plurality of ejection units each including a plurality of nozzle openings through which droplets of liquid are ejected, a pressure chamber communicating with the nozzle openings, and a pressure generator capable of generating a pressure change in the liquid in the pressure chamber, the liquid being supplied from a liquid source through a liquid supply channel to the pressure chambers and being ejected through the nozzle openings in a form of droplets by the pressure generators. The ejection unit group is sectioned into a plurality of unit blocks each constituted by a plurality of sets of the ejection units. Each of the unit blocks is provided with a block common channel, a distribution channel communicating with the liquid supply channel and the block common channel, and individual supply channels extending from the block common channel to the pressure chambers of the ejection units. The liquid supplied through the liquid supply channel is distributed through the distribution channels to the block common channels and is further supplied from the block common channels through the individual supply channels to the ejection units in the unit blocks. Droplets of the liquid are simultaneously ejected through the nozzle openings provided in the pressure chamber in each ejection unit upon driving of the corresponding pressure generator.
