Liquid packs 34 provided with liquid leading members 42 are stored in a container case 31 that is constituted by fitting a case main body portion 32 and a lid case 33 in fitting portions 27 and 28, support portions 13, which positions the liquid leading members 42 so as to be opposed to liquid introducing members 71 attached to a cartridge inserting portion 13, are provided on a front surface 32a of the container case 31, the fitting portions 27 and 28 are arranged in a state in which the fitting portions 27 and 28 traverses the support portions 43, and space portions 29 and 30 having a gap larger than a gap formed in the fitting portions 27 and 28 are formed near the support portions 43 in the fitting portions 27 and 28. In this way, liquid flowing through the fitting portions 27 and 28 due to the capillarity is retained by the space portions 29 and 30 and never flows to the fitting portions 27 and 28 further extending from the space portions 29 and 30.

The printer 10 executes an ink end detection process A while a print job is underway and an ink end detection process B when a print job has been completed. In the ink end detection process A, the printer 10 applies a first drive signal to detect that the amount of ink housed in the ink cartridge CA is equal to or less than a prescribed amount. In the ink end detection process B, the printer 10 applies a second drive signal to detect that the amount of ink housed in the ink cartridge CA exceeds the prescribed amount.

An ink cartridge in which on one surface of a cartridge case, there are provided a positioning means used in case that the ink cartridge is attached to a recording apparatus, an ink outlet port from an ink pack, an inlet port of the pressurized air and a connection terminal of a circuit board having a data storage means that stores ink information of the cartridge therein, and an ink jet recording apparatus provided with its ink cartridge are provided. According to the ink cartridge of this mode, since the cartridge is exactly positioned and fixed to a holder three-dimentionally by the positioning means, mechanical positional adjustment and electrical connection can be exactly performed, so that operation reliability of the recording apparatus can be improved. Further, in the recording apparatus of this mode, in a state where the cartridge has been mounted on the recording apparatus by the positioning means, the connection terminal of the board is located at the upper portion of the ink outlet port. Hereby, even if ink leaks from the ink outlet port, the connection terminal can be prevented from being stained with the ink.

A liquid cartridge is provided that supplies liquid to a liquid ejecting apparatus by being mounted in the liquid ejecting apparatus. The liquid cartridge includes a cartridge body having a side face in which an opening is formed; and a flexible film for forming an ink accommodating chamber that is a closed space for accommodating the liquid, with the cartridge body by covering the opening of the cartridge body. The flexible film is caused to deform toward the ink accommodating chamber by atmospheric pressure that acts on the flexible film when the liquid cartridge is got out from a vacuum bag in which the liquid cartridge is packaged, thereby increasing the pressure in the ink accommodating chamber.

An ink cartridge comprises an upper cover, and the inside of an inner frame portion of the upper cover is partitioned into a groove and a waste ink storing portion by a wall portion. A waste ink absorber is accommodated in the waste ink storing portion, and the inner frame portion is sealed with a film in this state so that a passage and a waste ink storing chamber are formed. The opening of a lower cover accommodating an ink pack therein is sealed with the upper cover thus constituted so that the ink cartridge is formed. Even if the ink cartridge is turned in various directions such that any surface of the lower cover acts as a lower surface, the position of the ink pack in the ink cartridge is always set to be higher than the liquid level of the ink in an ink bag.
