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 roomthat ejects an ink column, charging electrodesA andB that charge ink dropletsgenerated from the ink column, and deflection electrodesA andB that deflect charged ink dropletsA; and a cover partthat has an ink droplet passing holethrough which the ink dropletsA deflected by the deflection electrodesA andB pass and covers the recording mechanism. The inkjet recording device causes the ink dropletsA to land onto a recording objectthat moves relative to a recording headto perform recording. A vent holeis provided in a lateral surface of the cover part
