LIQUID SUPPLYING SYSTEM HAVING SENSOR FOR SENSING LIQUID LEVEL IN TANK STORING LIQUID FOR SUPPLYING TO HEAD

摘要

A liquid supplying system includes a cartridge, a tank, and a detecting portion. The liquid stored in a first storage chamber of the cartridge is flowed into a second storage chamber of the tank through an inlet opening. The liquid stored in the second storage chamber is discharged through an outlet opening. The second storage chamber includes a first portion, a second portion, and a third portion. The second portion is positioned below the first portion and has a horizontal cross-sectional area greater than a horizontal cross-sectional area of the first portion. The third portion is positioned above the first portion and has a horizontal cross-sectional area greater than a horizontal cross-sectional area of the first portion. The outlet opening is in communication with the second portion. The detecting portion is configured to detect the level of liquid stored in the first portion.
