Abstract
An ink jet recording apparatus includes a cap to cover the discharge ports for discharging ink. This cap includes an atmospheric conduction passage for conductively connecting the interior of the cap with the air outside, and an ink exhausting device for exhausting ink deposited in the interior of the cap to the outside preferably by utilizing the ink's own weight. With this cap structure, ink is exhausted outside the cap, thus reliably coping with ink leakage that might otherwise take place when ink tanks are replaced or the main body is vibrated. At the same time, it is made possible to maintain the atmospheric conduction passage in good condition at all times.
