  • Patent number: 9511590
    Abstract: A liquid supply apparatus includes plural outlet flow paths respectively connected to the plural mounting units in which plural liquid storing bodies are respectively mounted, a supply flow path to which the plural outlet flow paths are connected, a switching unit capable of switching a communication status of each outlet flow path with the supply flow path, and a pressurizing and supplying unit that pressurizes and supplies liquid in the liquid storing bodies to the supply flow path. If the amount of liquid remaining in the liquid storing body communicating with one of the outlet flow paths is less than or equal to a second threshold greater than a first threshold, liquid in the liquid storing body communicating with another outlet flow path different from the one outlet flow path is made ready to be pressurized and supplied.
