To enable a coupling terminal member of an ink cartridge and a coupling terminal of a printing apparatus to be in certain and increase a degree of freedom on installation position of a coupling terminal member of the cartridge, a cartridge installed in a printing apparatus for supplying the printing apparatus with ink includes an ink cartridge body for containing ink, an ink supply section on which an ink supply opening placed on or near a first sidewall of the ink cartridge body is formed, a memory for storing information on ink in the ink cartridge body, a contact terminal member on a second sidewall of the ink cartridge body coupled to the memory and a positioning member, which protrudes from the second sidewall, for positioning the ink cartridge properly with respect to the printing apparatus when the ink cartridge is installed in the printing apparatus.

Printing apparatus and ink cartridge therefor

Liquid packs provided with 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 and, 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 are arranged in a state in which 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. In this way, liquid flowing through 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.

Liquid container with structure for controlling leaked liquid

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 for a liquid ejection apparatus includes: a case having a liquid containing portion in its interior; a supply portion which is formed on a first side wall of the case, and through which a liquid in the liquid containing portion can flow to an exterior; a contact portion, which can contact a part of a slider of the liquid ejection apparatus to move the slider in a direction in which the liquid container is inserted; and an engagement portion, which is configured to engage a lock portion of the slider. The contact portion and the engagement portion are formed on a second side wall of the case, the second side wall intersecting the first side wall.

Liquid container

An ink cartridge having a container for storing ink therein and having an ink supply port formed at a leading end side in an insertion direction of the container, a memory device disposed on a first of two opposite surfaces parallel to the insertion direction of the container, the memory device having an electrode for electrical connection to the recording device; a retaining member disposed on the first surface and located at a trailing end side relative to the memory device in the insertion direction, the retaining member serving to selectively engage with the recording device; and another retaining member disposed on the second surface and which also serves to selectively engage with the recording device.

Ink cartridge

When ink is filled into an ink packincluding a bag partand an outlet part, firstly, air in the bagand outlet partis sucked by a suction pump Pprovided for an ink pouring apparatus. Further, by a first measuring pipe, ink supplied from a main tankis poured through the outlet partinto the bag part. Further, by a second measuring pipe, the ink poured into the bag partof the ink packis sucked and exhausted. Furthermore, the ink in the second measuring pipeis mixed into a mixing tankwith ink previously supplied to the mixing tankfrom the main tank. Next, the ink is supplied from the mixing tankto a third measuring pipe, and filled from the third measuring pipethrough the outlet partinto the bag part

An ink cartridge for an ink jet recording device, includes: a container having an ink supply port; at least two ink chambers partitioned in the container, one being located substantially in an upper section and the other being located substantially in a lower section; an ink suction passage connecting a bottom region of the lower section ink chamber to a bottom region of the upper section ink chamber; and a negative pressure generating mechanism provided to a flow passage connecting the upper section ink chamber to the ink supply port.

Ink cartridge for ink jet recording device

The ink cartridge includes an ink supply port formed at a position, offset to one side, of a wall configuring an ink container body; a positioning projecting portion, formed on one wall out of two opposing walls adjacent the wall, whose upper surface and side portion are regulated in position when the cartridge has been mounted on a recording apparatus; a lever, formed on the other wall out of the two walls, maintaining a normal hinged-open state and having a projection that is forcibly displaced outward when the cartridge is mounted on the recording apparatus; and electrodes that are connected to a memory unit storing information on the ink in an ink container and formed on the positioning projecting portion.

Ink cartridge and recording apparatus

An ink-jet recording device for supplying ink to a recording head from at least one ink cartridge having a bottom wall, and first and second side walls connected to each other through the bottom wall and facing each other, the ink cartridge further having an ink supply port at the bottom wall, a first retaining member extending from the first side wall and a recess provided in the vicinity of the second side wall, the retaining member having a first engagement portion displaceable toward and away from the first side wall. The recording device comprises a carriage having at least one ink cartridge mounting region adapted to receive the ink cartridge, a plurality of one identification members that are protruded from a bottom of the ink cartridge mounting region in a direction parallel to an insertion direction of the ink cartridge into the carriage, and that are positioned and configured so that the identification members are received by the recess of the ink cartridge when the ink cartridge is compatible to the ink cartridge mounting region; an ink supply needle positioned in the bottom of the ink cartridge storage region and configured for connection to the ink supply port of the ink cartridge, and a first engagement portion positioned and configured to engage the engagement portion of the ink cartridge.

Ink-jet recording device and ink cartridge

An ink cartridgeis detachably connected to a head of a record apparatus and has a container main bodyhaving an ink tank chamberopened to the atmosphere in a state in which the head and the cartridge are connected and a first openingthrough which ink can be injected into the ink tank chamber (second ink storage chamber, etc.,). Such an intermediate wallpartitioning the ink tank chamberinto two space partsandplaced side by side in an ink injection direction is disposed in the ink tank chamberand is formed with a through partthrough which ink can be injected.
