LIQUID EJECTING APPARATUS

摘要

A liquid ejecting apparatus includes: an inflow channel to which liquid is supplied; an outflow channel communicated with a nozzle; a liquid chamber formed with a spiral flow channel having a substantially constant cross-sectional area between the inflow channel and the outflow channel and having a given volume; a volume changing portion configured to deform the liquid chamber so as to change the volume of the liquid chamber to a volume smaller than the given volume; and an ejection control unit configured to cause the liquid to be ejected from the nozzle in a pulsed manner by driving the volume changing portion in a state in which the liquid chamber is filled with the liquid.
