摘要

As emission state of the liquid drop is made to stabilize with pressure state as uniform without receiving the restriction of liquid kind, easily various liquid kinds offer the emission method and liquid storage unit of the liquid drop which uses the liquid drop emission device and the liquid drop emission device which can modify and use. As the discharge head 10, the liquid drop from nozzle 13 with the drive of electric drive element 12 and the liquid is stored it has with the liquid storage unit 20 which is supplied to head 10. Liquid storage unit 20 was arranged has had long passage 40 almost horizontally.
