Patent ID: 8162475

Claim:
An inkjet recording apparatus, comprising: a feeder configured to contain a recording medium and configured to feed the recording medium to a conveyor, wherein the conveyor is configured to convey the recording medium fed by the feeder in a first direction; an inkjet head comprising an ejection face on which an ejection region is formed, the ejection region having a plurality of ink ejection openings arranged along a second direction perpendicular to the first direction, wherein the length of the ejection region in the second direction is greater than the length of the ejection region in the first direction; a detection unit configured to detect one end of the recording medium in the second direction; a mover configured to move the inkjet head in the second direction in accordance with the position of the one end of the recording medium detected by the detection unit, and a controller configured to control the feeder, the conveyor, the inkjet head, and the mover, wherein: the detection unit comprises a sensor moved along with the inkjet head by the mover, the sensor having a detection face which detects the recording medium; the controller is configured to control the mover to move the inkjet head and the sensor from a first position in which the detection face does not face the one end of the recording medium to a second position in which the detection face faces the one end of the recording medium, and to stop the inkjet head and the sensor at the second position; and the controller is configured to control the conveyor and the inkjet head, when the inkjet head and the sensor are stopped at the second position, such that ink is ejected from the ink ejection openings onto the recording medium when the recording medium is conveyed by the conveyor and passes through a recording position in which the recording medium faces the ejection face.
