1. A liquid discharging apparatus, comprising:
a head configured to discharge liquid;
a reservoir section, having:
a liquid reservoir chamber;
an air chamber connected with the liquid reservoir chamber;
an injection port connecting the liquid reservoir chamber and outside of the reservoir section, the injection port being configured to accept the liquid; and
an atmosphere communication path connecting the air chamber and the outside of the reservoir section,
a valve configured to open and close the atmosphere communication path;
a switching assembly configured to switch states of the valve between an opening state, in which the valve opens the atmosphere communication path, and a closing state, in which the valve closes the atmosphere communication path; and
a controller configured to
control the valve through the switching assembly to close the atmosphere communication path before the liquid is injected through the injection port;
control the valve through the switching assembly to open the atmosphere communication path after the liquid is injected through the injection port;
control the valve through the switching assembly to close the atmosphere communication path before discharging the liquid; and
control the head to discharge the liquid with the atmosphere communication path being closed.
