摘要： An ink cartridge is partitioned into a negative pressure generator chamber containing a negative pressure generator and a storage chamber containing an ink bag. The ink bag stores ink and supplies the ink to the negative pressure generator chamber through an ink port. The negative pressure generator absorbs and holds the ink by its capillary force, to keep pressure inside nozzles of a recording head negative to atmospheric pressure. Through a first air introduction hole, the air is introduced into the negative pressure generator chamber as the ink in the negative pressure generator chamber decreases. Through a second air introduction hole, the air is introduced into the storage chamber as the ink in the ink bag decreases. So variations in pressure inside the nozzles are suppressed, which makes ink discharge from the nozzles stable.
摘要翻译：墨盒被分隔成负压发生器室，该负压发生器容纳有负压发生器和容纳墨袋的储存室。墨水袋存储墨水并通过墨水口将墨水供应到负压发生器室。负压发生器通过其毛细管力吸收和保持墨水，以将记录头的喷嘴内的压力保持为大气压力。通过第一空气引入孔，当负压发生器室中的墨水减少时，空气被引入负压发生器室。通过第二空气引入孔，当墨袋中的墨水减少时，空气被引入储存室。因此，抑制了喷嘴内的压力变化，这使得喷嘴的墨水排出稳定。
