An ink cartridge 1 attachable to an ink jet printer, includes a liquid chamber 5 for accommodating an ink liquid 4, a liquid supply port 7 to be connected to a liquid receiving portion 2a on the ink jet printer side, a liquid passage 9 for causing the liquid chamber 5 to communicate with the liquid supply port 7, and an ink end sensor 13 forming a part of the liquid passage 9 and serving to detect a presence or absence of the ink liquid 4 in the liquid chamber 5, The liquid passage 9 on a downstream of the ink end sensor 13 is provided with a buffer chamber 15 capable of storing the ink liquid 4 to be supplied to the liquid supply port 7 and supplying the ink liquid in a constant amount after the ink end sensor 13 detects that the liquid is not present. An amount of storage of the liquid in the buffer chamber 15 is set to be substantially 10% of an effective amount of the ink liquid to be accommodated in the liquid cartridge 1.

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.

The invention provides a liquid consumption apparatus including a liquid consumption unit, a counting unit that counts the amount of the liquid consumed by the liquid consumption unit as a liquid consumption amount, a reception unit that receives a detection signal indicating that the amount of the liquid contained in the liquid container is not more than a predetermined amount; a detection-time liquid amount memory unit that memorizes the liquid consumption amount at the time of reception of the detection signal as a detection-time liquid consumption amount, and a judgment unit that judges that the liquid container is empty when the amount of difference between the liquid consumption amount and the detection-time liquid consumption amount is not more than a specified amount.

According to one aspect of the invention, a remanufacturing method of a liquid container forms an inlet in a certain area, for example, a buffer chamber, other than a specific section including liquid reservoirs and flow paths adjoining to and directly communicating with a bubble trap flow path in the liquid container. In the state of closing a liquid feeder and opening an air open structure, the remanufacturing method injects a liquid through the inlet to fill a space in the upstream of the inlet with the liquid. In the state of opening the liquid feeder and closing the air open structure, the remanufacturing method injects the liquid through the inlet to fill a space in the downstream of the inlet with the liquid. The remanufacturing process seals the inlet after completion of the injection of the liquid. This arrangement enables the liquid to be refilled into the liquid container without damaging the functions of the liquid container.

A liquid storage container prevents sucking of air bubbles into a liquid guide path, even when the amount of liquid remaining in the liquid storage chamber is reduced. The amount of liquid discarded, without being used, is reduced. A liquid storage container includes liquid storage chambers from which liquid is guided to a liquid-supplying unit through a liquid guide path and a liquid remaining-amount sensor for detecting the presence/absence of the liquid on the basis of variation in residual vibration that occurs when air bubbles enter the liquid guide path. The liquid storage chambers have concavities in the bottom walls thereof. Liquid outlets that communicate with the liquid guide path are formed at the bottom of the concavities, respectively. Therefore, air layers in the liquid storage chambers are prevented from coming into contact with the liquid outlets, respectively, before the remaining liquid does.

Liquid packs provided with the liquid leading members are stored in a container case that is constituted by fitting a case main body portion and a lid case in fitting portions, support portions, which positions the liquid leading members so as to be opposed to liquid introducing members attached to a cartridge inserting portion, are provided on a front surface of the container case, the fitting portions traverses the support portions, and space portions having a gap larger than a gap formed in the fitting portions are formed near the support portions in the fitting portions due to the capillarity is retained by the space portions and never flows to the fitting portions further extending from the space portions.

A liquid container includes a container body formed with a liquid supply port, and a container-side fixing structure which releasably regulates movement of the liquid container in an outward pulling direction in cooperation with apparatus-side fixing structure provided for the container mounting part in a state where the liquid container is mounted onto the container mounting part. The container-side fixing structure has a guide groove into which a fixing pin of the apparatus-side fixing structure can be inserted, and which guides the fixing pin in mounting and removal operations of the liquid container to and from the container mounting part. The guide groove includes a fixing part which engages the fixing pin to regulate the movement of the liquid container in the pulling direction in the state where the liquid container is mounted to the container mounting part. A slanted entrance surface is located at an entrance part of the guide groove, which slanted entrance surface slants so that a groove depth decreases in the movement direction of the fixing pin that relatively moves in association with an inserting operation of the liquid container into the container mounting part.

A high-performance liquid-supplying system is provided in which cost reduction can be achieved with a simple system configuration and accuracy in detecting the residual amount of liquid is high. An ink-supplying system 1 supplies liquid reserved in a main tank 14 to a recording head 3 through a subtank 16 mounted on a carriage 6. The main tank 14 has a structure opened to the atmosphere, and the subtank 16 has a sealed structure. The subtank 16 has liquid-detecting means 21 including a vibrating plate 31 as a part of a liquid supply channel 18 or a temporary reservoir 16a and a piezoelectric actuator 32 provided on the vibrating plate 31.
