A liquid supply unit includes an outer shell, a liquid supply portion that is arranged in the outer shell and can supply a liquid to the liquid ejection apparatus, and an engaged structure including an engaged portion that can engage with the engagement portion of the liquid ejection apparatus, and a first opening that is formed in the outer shell and through which the engagement structure can be inserted. The engaged portion is arranged further inward than an outer surface of the outer shell.

Liquid supply unit

A liquid supply unit includes an outer shell; a contact portion that is disposed in the outer shell and that is configured to electronically connect to the apparatus-side terminal by making contact with the apparatus-side terminal; a liquid supply port that is disposed on the outer shell and used for inserting the liquid introducing portion; and a receiving portion that extends in a protruding direction in which the guide member protrudes outward in a mounting state in which the liquid supply unit is mounted onto the liquid ejection apparatus, and that is configured to receive the guide member. At least a part of the receiving portion is located between the liquid supply port and the contact portion in a predetermined direction orthogonal to a direction in which the receiving portion extends.

An object is to identify an abnormal mounted state of a liquid supply unit to a liquid ejection apparatus. There is provided a liquid supply unit configured to supply a liquid to a liquid ejection apparatus that comprises a first electrode assembly including a first electrode and a second electrode; an engagement structure; and a mounting structure which the liquid supply unit is mounted to. The liquid supply unit comprises a liquid supply portion; an engaged structure configured to be engaged with the engagement structure in a mounted state and thereby restrict a motion of the liquid supply unit in a first direction that is a direction of dismounting the liquid supply unit; and an electrically conductive portion provided in the engaged structure. The electrically conductive portion is configured to come into contact with the first electrode and the second electrode in an engaged state that the engaged structure is engaged with the engagement structure, so as to provide electrical continuity between the first electrode and the second electrode and cause the liquid ejection apparatus to detect mounting of the liquid supply unit to the liquid ejection apparatus.

A liquid supply unit that includes a liquid ejection apparatus and configured to be mounted onto a holder unit that has a liquid introducing needle that extends in a first direction includes an outer shell, a liquid supply port, and an engagement structure including a first engagement portion, in which the first engagement portion is disposed on a mounting direction side of the outer shell at a position that overlaps with the outer shell when the liquid supply unit is viewed from the demounting direction side.

An attachment is mountable on a carriage in place of a liquid container that contains liquid and that is mounted on the carriage having a liquid jet head for jetting liquid, so that the attachment can supply liquid introduced from outside to the liquid jet head. The attachment has a pressure control means provided in a flow passage which is formed in an attachment body and through which the liquid introduced from the outside is supplied to the liquid jet head.

Attachment and attachment system

A circuit board of an ink cartridge is provided with a plurality of terminals, with the contact portions of the plurality of terminals forming a plurality of lines. The contact portions of two terminals used for detecting installation are positioned in a first line, and the contact portion of a power terminal is positioned between the two terminals. The first line may be positioned to a leading side when the ink cartridge is moved in a prescribed direction to effect installation in a printer. Alternatively, the first line may be the line closest to an opening of an ink delivery port. Alternatively, the first line may be the line closest to an ink delivery needle.

Recording material delivery system for recording material-consuming apparatus; circuit board; structural body; and ink cartridge

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.

Liquid container, method of filling liquid into liquid container, and remanufacturing method of liquid container

A method of manufacturing a liquid container, the liquid container including a liquid containing chamber in which a liquid can be contained, an air communicating passage allowing the liquid containing chamber to communicate with the air, a liquid supply port for supplying the liquid contained in the liquid container to an outside, a liquid flow passage allowing the liquid container and the liquid supply port to communicate with each other, a valve accommodating chamber disposed in the liquid flow passage, a differential pressure valve which is disposed in the valve accommodating chamber, which is normally urged to a closed state, and which is changed from the closed state to an opened state when a differential pressure of a side of the liquid supply port and a side of the liquid containing chamber is equal to or more than a predetermined value, and a film member forming a part of the valve accommodating chamber, the method includes: pressing a valve body of the differential pressure valve in a direction in which the differential pressure valve is opened; and injecting the liquid from the liquid supply port to the liquid containing chamber via the liquid flow passage while maintaining the opened state of the differential pressure valve.

Method of manufacturing liquid container and liquid container

A method of injecting a liquid into a liquid container detachably mounted on a liquid consuming device, the liquid container including: a liquid containing chamber in which the liquid can be contained; a liquid supply hole connectable to the liquid consuming device; a liquid guide passage for guiding the liquid contained in the liquid containing chamber to the liquid supply hole; an air communicating passage communicating the liquid containing chamber with an air; and a liquid residual quantity sensor provided in the liquid guide passage and for outputting different signals between in a case where the liquid guide passage is filled with the liquid and in a case where the liquid guide passage includes air entered thereinto, wherein the liquid containing chamber including at least three liquid containing chambers, and wherein the liquid containing chambers are mutually connected so as to have a descending connection where a pair of the liquid containing chambers are mutually connected so that a liquid flow in the liquid guide passage is a descending flow from above to below and an ascending connection where a pair of the liquid containing chambers are mutually connected so that the liquid flow in the liquid guide passage is an ascending flow from below to above, the method includes: forming an injection port, which communicates with the liquid containing chamber, in the air communicating passage; injecting a predetermined amount of liquid through the injection port; and sealing the injection port after injecting the liquid.

Liquid injecting method and liquid container

A liquid container adapted for installation in a liquid jetting device includes an installation status notifier portion. The installation status notifier portion, in an installed state wherein the liquid container is installed in the liquid jetting device, is able to make the liquid jetting device determine that there exists the installed state, and alternatively to make the liquid jetting device determine, even in the installed state, that there exists a non-installed state wherein the liquid container is not installed in the liquid jetting device.
