Patent number: 8079682Abstract: An inkjet recording device has an ink tank, a reservoir and an ink head, forms an ink supplying system by connecting with a path between the ink tank and the reservoir and between the reservoir and the ink head respectively, and forms a meniscus by generating a negative pressure on an ink discharging plane of the ink head by opening the reservoir to atmosphere. The inkjet recording device includes control electromagnetic valves to open or interrupt paths of the ink supplying system and valve switching control means for controlling opening/closing of the control electromagnetic valves, and controls the valve to be closed by the valve switching control means when the device vibrates. As a result, even if an ink liquid level in the reservoir changes when the device vibrates, transmission of this change to the meniscus of the ink discharging plane is prevented or suppressed.Type: GrantFiled: March 31, 2009Date of Patent: December 20, 2011Assignee: Riso Kagaku CorporationInventors: Asayo Nishimura, Masato Hirai, Hitoshi Arai
