Abstract
There is provided an ink jet recording apparatus capable of preventing a user from erroneously performing an opening and closing operation of a valve in the supply of ink to a recording head from an ink tank. The ink jet recording apparatus includes a recording head configured to eject ink, an ink tank provided in an apparatus body, including an filling portion for filling ink to be supplied to the recording head, and configured to store the filled ink, a cover member configured to be movable to a position where the filling portion is not exposed and a second position where the filling portion is exposed, and a valve configured to be switchable between an opened state where ink can be supplied to the recording head from the ink tank and a closed state where the supply of ink to the recording head from the ink tank is blocked, wherein the valve operates interlocking with the movement of the cover member, and is in the opened state when the cover member is at the first position and in the closed state when the cover member is at the second position.
