20090015642 | Liquid Storage Container and Liquid Filling Method and Liquid Refilling Method Using the Same - A liquid storage container includes a liquid containing body that is formed of a flexible film and contains liquid therein; a liquid lead-out member connected to the liquid containing body; and a spacer member disposed in the liquid containing body. The liquid containing body deforms in a direction in which inner wall surfaces of the flexible film facing each other are brought into contact with each other at the time of reduction in the remaining amount of the liquid as the inside liquid is taken out through the liquid lead-out member, and the spacer member regulates contact between parts of the inner wall surfaces of the flexible film facing each other at the time of reduction in the remaining amount of the liquid to thereby form a remaining liquid space where liquid remains. | 01-15-2009 |
20090219336 | LIQUID EJECTING APPARATUS - A liquid ejecting apparatus includes: a sub-tank which stores a certain volume of liquid; a liquid ejecting head which ejects the liquid supplied from the sub-tank; a sheet feeding drum which feeds an ejection target medium to be ejected with the liquid by rotation; a liquid container which stores the liquid to be supplied to the sub-tank; and a supply passage which connects the sub-tank to the liquid container so that the liquid is supplied from the liquid container to the sub-tank. The sheet feeding drum includes a liquid container receiving chamber receiving the liquid container and the liquid container receiving chamber communicates with the supply passage. | 09-03-2009 |
20090244224 | LIQUID JETTING SYSTEM, LIQUID CONTAINER, HOLDER, AND LIQUID JETTING APPARATUS HAVING HOLDER - A liquid jetting system includes a liquid container including a front wall, and a side wall having a bias-force receiving part, and a liquid jetting apparatus including a holder that receives installation of the liquid container through insertion of the liquid container in a prescribed insertion direction with the front wall facing forward. The holder further includes a liquid feed needle that receives feed of liquid from the liquid container when the liquid container has been installed, a holder-side electrode situated to a upper side from the liquid feed needle and adapted to electrically connect with the liquid container when the liquid container has been installed, and bias force part situated to a lower side from the liquid feed needle and adapted to exert a bias force on the bias-force receiving part of the liquid container in a prescribed biasing direction when the liquid container has been installed. The liquid container further includes a feed part having a liquid feed port that opens onto the front wall and that receives insertion of the liquid feed needle when the liquid container has been installed in the holder, and a container-side electrode that is to be secured at such a location as to electrically connect with the holder-side electrode when the liquid container has been installed in the holder. The biasing direction is established such that an extended line extending in the biasing direction from the bias-force receiving part is offset from the container-side electrode towards the side wall side. | 10-01-2009 |
20090251517 | LIQUID STORAGE DEVICE AND LIQUID PRESENCE DETERMINING METHOD - A liquid storage device includes a storage portion that is configured to store liquid therein, a rotating member that is provided in a bottom portion at inside of the storage portion so as to be capable of rotating, a driving member that is provided at outside of the storage portion in a non-contact state with respect to the rotating member so as to drive the rotating member by magnetic force, the driving member rotating to allow the rotating member to rotate, a detecting portion that is capable of detecting a degree of rotation of the rotating member, and a determining portion that is capable of acquiring difference information of rotation between the rotating member and the driving member on the basis of a detection result by the detecting portion and determining presence of liquid in the storage portion on the basis of the difference information. | 10-08-2009 |
20120125481 | LIQUID FILL CONTAINER - There is provided a liquid fill container that is used to fill a liquid reservoir supplying a liquid to a liquid ejecting apparatus, with the liquid. The container includes a containing unit that contains the fill liquid; a filling port that is inserted into an inlet of the liquid reservoir, and that allows the liquid contained in the containing unit to flow therethrough to fill the liquid reservoir; and a positioning member that maintains the position of the filling port and the position of the liquid reservoir with respect to each other in the direction in which the filling port is inserted into the liquid reservoir during liquid filling of the liquid reservoir. | 05-24-2012 |
20120194608 | LIQUID EJECTING APPARATUS - A liquid ejecting apparatus includes a pressure control unit provided in a liquid flow path so as to control pressure. The pressure control unit includes a liquid introduction unit, a liquid chamber having a diaphragm, a communication hole that allows communication between the liquid introduction unit and the liquid chamber, and a wall portion provided on the side of the liquid chamber, so as to switch between a first mode in which the wall portion forms a first flow path for the liquid flowing through the communication hole toward the liquid outlet without contacting the diaphragm in accordance with a pressure in the liquid chamber, and a second mode in which the wall portion forms a second flow path different from the first flow path, in contact with the diaphragm. | 08-02-2012 |
20120194620 | LIQUID EJECTING APPARATUS - A liquid ejecting apparatus includes a pressure control unit provided in a liquid flow path so as to control pressure. The pressure control unit includes a liquid introduction unit, a liquid chamber having a diaphragm, a communication hole that allows communication between the liquid introduction unit and the liquid chamber, a movable member including an opposing surface disposed on the side of the liquid chamber so as to oppose the communication hole, the movable member being disposed so as to move in response to the displacement of the diaphragm unit, and a displacement member that displaces the opposing surface between a first posture of opposing the communication hole and a second posture in which the opposing surface is tilted with respect to the communication hole in an angle different from the first posture. | 08-02-2012 |
20150191016 | DROPLET EJECTING APPARATUS - A droplet ejecting apparatus includes a droplet ejecting unit provided with ejecting ports capable of ejecting a solution onto a medium as droplets; a cap portion which performs capping in which a region to which the ejecting ports are open is set to a closed space; a gas supply portion capable of supplying a humidified gas to the closed space; and a liquid supply portion capable of supplying a liquid for humidifying the closed space. | 07-09-2015 |
20150191022 | LIQUID EJECTING APPARATUS - A liquid ejecting apparatus includes a liquid flow path connecting a liquid containing unit that contains a liquid to a liquid ejecting unit that ejects the liquid. The liquid flow path includes a supply flow path which connects the liquid containing unit to the liquid ejecting unit and a return flow path which connects the liquid ejecting unit to the liquid containing unit. When the liquid is not ejected by the liquid ejecting unit, the liquid contained in the liquid containing unit is circulated between the liquid containing unit and the liquid flow path by allowing the liquid to flow in order of the supply flow path, the liquid ejecting unit, and the return flow path. When the liquid is ejected, the liquid contained in the liquid containing unit is supplied to the common liquid chamber via both of the supply flow path and the return flow path. | 07-09-2015 |
