<P>PROBLEM TO BE SOLVED: To facilitate changing of the number of types of liquid supplied by using a liquid supply device. <P>SOLUTION: The liquid supply device includes: a liquid supply unit; and a pressure pump. A liquid chamber to which an inflow passage and an outflow passage are connected, and an air chamber in contact with the liquid chamber via a flexible partition plate are formed in the liquid supply unit. When a positive pressure or negative pressure is introduced in the air chamber by the pressure pump, the partition plate is deformed, and the volume of the liquid chamber changes consequently. Additional installation of a liquid supply unit is enabled by connecting an air chamber of the new liquid supply unit to the air chamber of the liquid supply unit. A suitable liquid supply device is made by simply connecting the same liquid supply units according to the number of routes for supplying the liquid, and the number of routes for supplying the liquid can be easily changed by using the liquid supply device. <P>COPYRIGHT: (C)2012,JPO&INPIT |
