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 6):
The image-recording apparatus according to  claim 1 , wherein the second storage chamber is positioned further in the first direction relative to the nozzle,\n wherein the second storage chamber includes a liquid-storage space and an air-communication space, the liquid-storage space being defined as a space positioned below a maximum liquid level provided by a predetermined maximum amount of liquid that can be stored in the second storage chamber, the air-communication space being defined as a space positioned above the maximum liquid level; wherein the liquid inlet port and the liquid outlet port are in communication with the liquid-storage space; and wherein the air-communication space of the second storage chamber has a prescribed portion positioned further in a second direction opposite to the first direction relative to the liquid outlet port, the prescribed portion of the air-communication space of the second storage chamber having a volume greater than a sum of a volume of the lower space of the first storage chamber and a volume of a portion of the liquid-storage space positioned further in the first direction relative to the liquid outlet port.
