Abstract:
An image-recording apparatus includes: a cartridge including a first storage chamber and a supply port; a tank including a second storage chamber and an inlet port; a connecting portion including a liquid channel providing communication between the supply port and the inlet port; and a detector for detecting whether a liquid level in the second storage chamber is at a prescribed position. The first storage chamber includes an upper space and a lower space partitioned by a wall formed with a communication opening. An inequality of Pm<ρ·Hs·g−Ic·Rn is satisfied, where: Pm: withstand pressure of meniscus formed at the communication opening; P: density of liquid; Hs: vertical length between the prescribed position and the communication opening; g: gravitational acceleration; Ic: flow rate of liquid from the first storage chamber to the second storage chamber; and Rn: passage resistance at the liquid channel.

Claim (Index 1):
An image-recording apparatus comprising:\n a cartridge comprising:\n a first storage chamber storing liquid; \n a liquid supply port through which the liquid in the first storage chamber is allowed to be supplied; and \n a first air communication portion configured to allow the first storage chamber to communicate with an atmosphere; \n a tank comprising:\n a liquid inlet port in communication with the first storage chamber through the liquid supply port; \n a second storage chamber in communication with the liquid inlet port and configured to store the liquid supplied from the first storage chamber through the liquid inlet port; \n a liquid outlet port allowing the liquid stored in the second storage chamber to be discharged therefrom; and \n a second air communication portion configured to allow the second storage chamber to communicate with the atmosphere; \n a connecting portion comprising a first liquid channel allowing the liquid to circulate between the liquid supply port and the liquid inlet port; a recording head in communication with the liquid outlet port through a second liquid channel, the recording head comprising a nozzle configured to eject the liquid supplied from the liquid outlet port through the second liquid channel; and a detector configured to detect whether or not a level of the liquid stored in the second storage chamber comes to a prescribed position, wherein the first storage chamber is defined by inner surfaces including an inner partitioning surface positioned close to the tank, the first storage chamber being partitioned by a wall portion into an upper space above the wall portion and a lower space below the wall portion, the wall portion extending from the inner partitioning surface in a first direction away from the tank, the wall portion being formed with a communication opening through which the upper space and the lower space communicate with each other; wherein the liquid supply port is in communication with the lower space of the first storage chamber; wherein the prescribed position of the liquid to be detected by the detector is positioned between the communication opening and the liquid supply port in a vertical direction; and wherein a following inequality (1) is satisfied:\n Pm<\u03c1\u00b7Hs\u00b7g\u2212Ic\u00b7Rn \u2003\u2003inequality (1), \n in which: Pm: withstand pressure of a meniscus of the liquid formed at the communication opening; P: density of the liquid; Hs: length in the vertical direction between the prescribed position of the liquid level detected by the detector and the communication opening; g: gravitational acceleration; Ic: flow rate of the liquid flowing from the first storage chamber to the second storage chamber when a level of the liquid in the first storage chamber is at the communication opening and the level of the liquid in the second storage chamber is at the prescribed position; and Rn: passage resistance at the first liquid channel.
