Abstract
The purpose of the present invention is to prevent the flow of air flowing from the outside of a cover part into the cover part via an ink droplet passing hole as air accompanying printing droplets outflows. An inkjet recording device is provided with: a recording mechanism (printing mechanism) having an ink room 101 that ejects an ink column 107, charging electrodes 103A and 103B that charge ink droplets 106 generated from the ink column 107, and deflection electrodes 105A and 105B that deflect charged ink droplets 106A; and a cover part 118 that has an ink droplet passing hole 117 through which the ink droplets 106A deflected by the deflection electrodes 105A and 105B pass and covers the recording mechanism. The inkjet recording device causes the ink droplets 106A to land onto a recording object 116 that moves relative to a recording head 100 to perform recording. A vent hole 130 is provided in a lateral surface of the cover part 118.
