Patent ID: 7014286

Claim:
A liquid jetting apparatus comprising; a container-setting portion at which a liquid container is set, the liquid container having a liquid chamber that contains liquid, a head member having a nozzle, a liquid way that can communicate with the liquid chamber of the liquid container set at the container-setting portion and the nozzle, a liquid discharging unit that can cause the liquid to be discharged from the nozzle, and a liquid discharging controller that can control the liquid discharging unit based on information about sedimentation-property of the liquid in the liquid chamber and information about sedimentation-state of the liquid in the liquid chamber, a clock component that knows a present time, and a sedimentation-state acquiring unit that can acquire the information about sedimentation-state of the liquid in the liquid chamber, wherein the information about sedimentation-state of the liquid in the liquid chamber is information about a point of time that is a standard for judgement of the sedimentation-state, the liquid discharging controller has: a calculating part that can calculate a passed time until the present time based on the information about a point of time that is a standard for judgement of the sedimentation-state, and a main controlling part that can control the liquid discharging unit based on the passed time, wherein: a liquid-consumption totaling unit that can total a liquid consumption from the nozzle, and a liquid-end determining unit that can determine a liquid end based on the information about a point of time that is a standard for judgment of the sedimentation-state and the liquid consumption.
