Abstract
A fluid ejection device ejecting a fluid, the fluid ejection device includes: a fluid ejection unit, a main chassis case, a fluid-containing pack, and a container case. The fluid ejection unit ejects a fluid onto an ejection target. The main chassis case houses the fluid ejection unit. The fluid-containing pack contains a fluid for ejection. The container case houses the fluid-containing pack. The container case is pivotably attached to the main chassis case and openable by rotation about a rotation shaft. The fluid ejection device further comprises a fluid passage, including a delivery tube with a bent section, in which fluid flows from the fluid-containing tank to the fluid ejection unit through the container case. The shape of the bent section changes by the opening and closing of the container case.
