Patent ID: 8020961

Claim:
An ink-jet recording apparatus comprising: an ink-jet head comprising an ejection face on which an ejection port that ejects ink is formed, a side face extending along a direction crossing the ejection face, and an ejection energy applier that applies ejection energy to ink thereby making ink ejected from the ejection port; an ejection control board that is fixed to the ink-jet head and electrically connected to the ejection energy applier; a head cover that is fixed to the ink-jet head so as to expose out the ejection face, and forms a container space that contains therein the ejection control board; an inflow port through which air passes into the container space; an outflow port through which air passes out of the container space; a filter that filters air; and an airflow generator that generates an airflow going into the container space through the inflow port and out of the container space through the outflow port, wherein the head cover comprises an open plane formed through an end thereof, through which open plane the ejection face of the ink-jet head is exposed to the outside of the head cover, wherein the outflow port is formed on the open plane between the ink-jet head and the head cover, wherein an airflow filtered by the filter goes out of the container space through the outflow port in a direction perpendicular to the ejection face and across a plane including the ejection face, and wherein: the container space is defined by the head cover, the ink-jet head, the inflow port, and the outflow port; and the filter is positioned near the outflow port.
