Abstract:
1. An inkjet recording apparatus comprising: a recording head that includes a sub-tank therein for storing ink and an ejection nozzle for conducting image recording on a recording medium by selectively ejecting the ink stored in the sub-tank therefrom, the sub-tank being provided with an air discharging unit having a communication hole that allows communication of an interior of the sub-tank with atmospheric air; a carriage that is equipped with the recording head and is capable of being reciprocated in a direction perpendicular to a conveyance direction of a recording medium; a movable body that includes a nozzle cap for covering a nozzle surface for the ejection nozzle of the recording head, the movable body being disposed so as to face the air discharging unit of the sub-tank and provided with an open-close switching member so as to switch a state of the communication hole between an open state and a close state corresponding to a change of a relative position of the nozzle surface with respect to the movable body; a moving mechanism that can change the relative position of the nozzle surface with respect to the movable body by moving the movable body; and a relative position controller that controls the moving mechanism for moving the movable body so as to change the relative position of the nozzle surface with respect to the movable body, the relative position controller switching a state of the inkjet recording apparatus into:
