There is provided a liquid container including: a pouch and a case. The pouch includes a flexible bag and a spout with a first opening. The case includes a tank to store a liquid flowed through the second opening. The spout is fitted into the case, and the bag is positioned in the tank.

Liquid container and liquid discharge apparatus

There is provided a liquid discharge apparatus including a head configured to eject a liquid from nozzles being open in a nozzle surface, a liquid absorbing wiper, and a support supporting the liquid absorbing wiper. The supporter is movable relative to the head, between a first position where the liquid absorbing wiper is in contact with the nozzle surface, and a second position where the liquid absorbing wiper is away from the nozzle surface, the supporter has a flow channel for a liquid cleaner to flow therethrough, and the liquid absorbing wiper sucks in the liquid cleaner from below by way of contact with the liquid cleaner flowing in the flow channel.

Liquid discharge apparatus

Aspects of a disclosure relates to a liquid discharge device enables previously disabled liquid discharge through a head after a cartridge including a first liquid chamber is replaced and before the liquid level in a second liquid chamber of a tank reaches a predetermined level or higher. Another aspect of the disclosure relates to a liquid discharge device that deactivates an alarm after a cartridge including a first liquid chamber is replaced and before the liquid level in a second liquid reaches a predetermined level or higher.

Liquid discharge device

There is provided a liquid discharge apparatus including: a head including a nozzle surface; a wiper including a blade and a blade holder; a posture changer configured to change a posture of the blade to a first posture in which the blade makes contact with the nozzle surface and to a second posture which is different from the first posture; and a cleaner including a cleaning surface intersecting the nozzle surface. The blade in the first posture is configured to move in a first sliding direction relatively with respect to the head in a state in which the blade makes contact with the nozzle surface. The blade in the second posture is configured to move in a second sliding direction intersecting the first sliding direction relatively with respect to the cleaner in a state in which the blade makes contact with the cleaning surface.

Aspects of a disclosure relates to a liquid discharge device enables previously disabled liquid discharge through a head after a cartridge including a first liquid chamber is replaced and before the liquid level in a second liquid chamber of a tank reaches a predetermined level or higher. Another aspects of the disclosure relates to a liquid discharge device that deactivates an alarm after a cartridge including a first liquid chamber is replaced and before the liquid level in a second liquid reaches a predetermined level or higher.

A liquid discharge apparatus is provided, which comprises a head, a maintenance mechanism which has a cap and which is movable to a maintenance position and a waiting position, a first support mechanism which supports the maintenance mechanism disposed at the maintenance position, and a second support mechanism which supports the maintenance mechanism disposed at the waiting position. One of the first and second support mechanisms is relatively movable to a first position and a second position with respect to the other. When the one of them is disposed at the first position, both of them is configured to support the maintenance mechanism simultaneously. When the one of them is disposed at the second position, the other of them is separated away from the maintenance mechanism.

A liquid discharge apparatus includes a case receiving a cartridge, a tank, a head, and a controller to: when the cartridge is installed in the case, calculate an outflow amount Qc based on heights Hc, Hs and flow path resistances; read the amounts Vc, Vs from a memory; subtract the outflow amount Qc from the read liquid amount Vc to calculate new liquid amount Vc; add the outflow amount Qc to the read liquid amount Vs to calculate new liquid amount Vs; store the calculated liquid amounts Vc, Vs in the memory; after a time period from at the time the calculated liquid amounts Vc, Vs stored elapses, again calculate the outflow amount Qc and the liquid amounts Vc, Vs and store the calculated liquid amounts Vc, Vs in the memory.

A liquid discharge apparatus is configured to activate a first notification in a case where a liquid level of a tank is less than a threshold. In a case where a cartridge is installed after activating the first notification, a controller determines outflow amount Vcs of the liquid flowing into the tank based on the liquid amount of the installed cartridge, and controls a notification device based on the determined outflow amount Vcs.

The liquid discharge device starts executing an initial process of discharging the liquid, based on determining that a low level signal is received after receiving a high level signal from an installation sensor and that a low level signal is received after receiving a high level signal from a liquid level sensor.

A liquid jetting apparatus includes: a head unit including nozzles; a cap which covers the nozzles in a state of being in contact with the head unit at a capping position; and a cap movement device including a cam having a slide surface and a cam follower which is slid on the slide surface. One of the cam and the cam follower is provided integrally with the cap, and the other of the cam and the cam follower is moved in a slide direction. The slide surface includes a first inclined surface inclined by a first angle relative to the slide direction and a second inclined surface inclined by a second angle greater than the first angle relative to the slide direction.

Liquid jetting apparatus

There is provided a liquid jetting apparatus including: a liquid jetting head which has a liquid jetting surface on which a plurality of nozzles are open to jet the liquid; a wiper which moves, relative to the liquid jetting surface, in a wiping direction along the liquid jetting surface, while being brought in contact with the liquid jetting surface, to wipe the liquid adhered on the liquid jetting surface; a wiper moving mechanism which moves the wiper in a direction orthogonal to the liquid jetting surface to approach to or separate from the ink jetting surface; a stopper which makes contact with the wiper which is separated from the ink jetting surface; and an impact-absorbing member which is formed in the wiper or the stopper and absorbs impact generated in a case that the wiper collides with the stopper.

A liquid discharge apparatus includes a case receiving a cartridge having a first chamber, a tank having a second chamber, a head, and a controller to: calculate outflow amount Qa flowed from the second chamber for a time period &#x394;t based on discharge amount Dh; calculate outflow amount Qc flowed from the first chamber toward the second chamber for the time period &#x394;t based on the outflow amount Qa and flow path resistances; read liquid amounts Vc and Vs of the first and second chambers from a memory; subtract the outflow amount Qc from the read liquid amount Vc to calculate new liquid amount Vc; subtract the outflow amount Qa from the read liquid amount Vs and add the outflow amount Qc to calculate new liquid amount Vs; and store the calculated liquid amounts Vc and Vs in the memory.

Liquid discharge apparatus and cartridge

The liquid discharge device determines a signal received from an installation sensor in response to receiving a discharge instruction, and when determined that a high level signal is received, control executing image recording in a first mode in which a waiting time Twis set, and control executing image recording in a second mode in which a waiting time Twis set.
