摘要： An ink chamber is formed with a vent port allowing atmospheric air to enter therein and an ink outlet from which ink is taken out. An optical member has an ink contact face capable of contacting with ink contained in the ink chamber. The ink contact face includes a detection face at which a remaining amount of ink in the ink chamber is optically detected in accordance with an amount of air entered into the ink chamber via the vent port. A first ink absorbing member is disposed in the vicinity of the ink contact face, and capable of absorbing the ink in the ink chamber.

摘要： A cartridge body is formed with a chamber storing ink and a recessed portion having an ink outlet port from which ink in the chamber flows out. An elastic gasket has a first through hole and is fitted into the recessed portion. A gasket stopper has a second through hole and is fitted into the recessed portion such that the gasket is pressed against an inner face of the recessed portion. A hollowed needle having a hole at a tip end thereof is inserted into the ink outlet port while passing through the first through hole and the second through hole and while enlarging the first through hole in order to supply the ink in the chamber to an ink jet recording head via the hole.

摘要： A printer and an ink tank for the printer capable of precisely detecting that ink has run out in a foam type ink tank. The ink chamber and an ink passage are formed in this order between the foam containing portion and the ink outlet of a foam-type ink tank. A first filter is installed between the foam containing portion and the ink passage and used to pass bubbles therethrough, whereas a second filter having a pore diameter smaller than the pore diameter of the first filter is installed between the ink chamber and the ink passage. A rectangular prism for detecting an ink end is formed on the side of the ink chamber. When the reflective surface of the rectangular prism is exposed from an ink liquid level as bubbles are gathered in the ink chamber with ink that is running short, light is reflected from the reflective surfaces and is detected by a reflection type optical sensor on the ink-jet printer side, so that the ink end can be determined. In a case where the capacity of the ink chamber is set sufficiently smaller, the ink end is detectable at a point of time when the ink has substantially run out.
