ABSTRACT:
A liquid feeding apparatus quantitatively feeds a liquid by pressing and clogging an elastic tube between a press roller and an arc-shaped guide portion through rotational motion of the press roller. The liquid feeding apparatus includes a main unit in which the press roller is provided, and a liquid cassette which accommodates a liquid cartridge. One end of the elastic tube is connected to a reservoir for the liquid to be fed, and the other end is connected to a check valve. The liquid cassette is removably fitted to the liquid feeding apparatus so that the elastic tube is subject to pressing action of the press roller.
