  • Patent number: 8020961
    Abstract: An ink-jet recording apparatus includes an ink-jet head formed with an ejection face, and an ejection control board fixed to the ink-jet head. A head cover forms a container space that contains therein the ejection control board. The container space has an air inflow port and an air outflow port. An airflow generator generates an airflow that goes into the container space through the inflow port and out of the container space through the outflow port. Through the outflow port, an airflow filtered by the filter goes out of the container space across a plane including the ejection face.
