Abstract
An inkjet recording apparatus includes a cartridge-attachment portion and an ink cartridge attachable thereto. The ink cartridge includes: a main body formed with an opening; an ink chamber disposed in the main body; a first valve opening and closing the opening; and a first pressing surface. The cartridge-attachment portion includes: an ink supply member providing an ink passage formed with an inlet; a second valve opening and closing the inlet; and a second pressing surface. In the attachment process, the ink supply member enters the ink chamber through the opening, the first pressing surface moves the second valve to a position opening the inlet, and the second pressing surface moves the first valve to a position opening the opening. In an attached state, the inlet is opened and positioned in the ink chamber, and the ink passage is in communication with the ink chamber through the inlet.
