Abstract
A liquid discharging apparatus includes: a liquid compartment; a flowing-in passage that is in communication with the liquid compartment through a flowing-in opening, the liquid flowing through the flowing-in passage into the liquid compartment; a nozzle that is in communication with the liquid compartment through a communication opening; a capacity changer that causes the liquid contained in the liquid compartment to be discharged from the nozzle by causing a displacement of an inner wall surface of the liquid component and changing capacity of the liquid compartment; and a flowing-in passage resistance changer that changes capacity of the flowing-in passage to change flow resistance of the flowing-in passage. In the liquid compartment, as viewed from the flowing-in opening, the communication opening is located in front of a center-of-displacement portion, an amount of the displacement of which is largest in the inner wall surface displaced by the capacity changer.
