摘要： An ink cartridge includes a cartridge body defining an ink chamber, an ink supply portion provided at the cartridge body, an air flow path provided in the cartridge body, a cover, and a memory chip disposed on the cover. The cartridge body has an outer surface oriented in a first direction and an air communication port opened on the outer surface. The air flow path communicates with the ink chamber through a communication hole and with ambient air through the air communication port to permit communication between the ink chamber and ambient air. The cover covers the outer surface of the cartridge body and has an opening at a position aligned with the air communication port in the first direction. The memory chip closes the opening and stores information. External access to the memory chip permits information to be electrically retrieved therefrom.

摘要： A volume of an ink-deliver chamber is efficiently utilized to dampen pressure changes of ink within the chamber, and prevent air bubbles produced in the chamber from flowing into an ink-jet recording head. In addition, an ink-jet recording apparatus having a plurality of ink-deliver chambers in a small space, is provided. Two ink cases are stacked on each other, which include two ink-deliver chambers that accommodate different inks. Open sides of the four ink-deliver chambers are closed by flexible films. An ink-deliver chamber has an ink-flow inlet through which ink is introduced, and an ink-flow outlet through which ink flows to the ink-jet recording head, and the ink-flow inlet and outlet are provided at respective positions that are substantially most distant from each other such that almost all portions of an inner space of the ink-deliver chamber, where ink flows, are located between the ink-flow inlet and outlet.

摘要： An ink-jet recording apparatus includes a recording head, an ink channel supplying the recording head with ink and a valve body controlling the supply of ink to the recording head in the ink channel. The ink channel has a valve accommodation room and a valve opening formed in a wall surface located at one end of the valve accommodation room. In an ordinary state the valve body is urged to be in contact with the wall surface and to close the valve opening. In that state, a first area of the valve body, on which a pressure in a direction of opening the valve body from the valve opening acts, is smaller than a second area of the valve body, which is on an opposite side to the first area and on which a pressure within the valve accommodation room acts.

摘要： A liquid jetting apparatus includes: a head; an ink storage chamber communicating with the head; a gas distributing chamber in which a gas introducing hole is formed; a buffer chamber in which a communicating hole for communicating with the gas distributing chamber, and an atmosphere opening hole for opening to the atmosphere are formed; a combination valve which is capable of opening and closing the gas introducing hole and the communicating hole; a gas introducing mechanism which introduces the compressed air through the gas introducing hole to the head to jet the ink forcibly, and a positive-pressure control valve which opens the atmosphere opening hole when a pressure in the buffer chamber exceeds a predetermined value. It is possible to operate a positive-pressure purge while suppressing an excessive increase in the pressure inside the liquid storage chamber, without increasing a size and a cost of the apparatus.

摘要： A print liquid cartridge comprises an ink chamber, a liquid supply portion, and a translucent portion. The ink chamber which accumulates ink therein is positioned between a front side in an insertion direction and a rear side in an opposite direction to the insertion direction. The liquid supply portion which supplies ink stored in the ink chamber to an exterior of the ink chamber is positioned at the front side. The translucent portion which is in fluid communication with an interior of the ink chamber is positioned at the front side. A light-transmitting state of the translucent portion changes in response to a change in the amount of the ink accumulated in the ink chamber. The ink supply portion projects farther forward from the rear side than the translucent portion.

摘要： An inkjet printer includes a recording head having nozzles to discharge ink and a storage chamber for storing the ink which is supplied to the nozzles from an ink source. The chamber includes an inlet to which the ink flows from the ink source and an outlet from which the ink flows out to the nozzles, two walls opposite to each other and parallel to a flow direction of the ink flowing to the outlet from the inlet, and an annular rim formed along edges of the two walls. The chamber includes a pair of ribs for adjusting an ink flow, which are provided in one of the walls, protrude from the one towards the other, and extend parallel to the flow direction apart from the other. The other wall has flexibility and the ribs are spaced from the rim inside the rim.

摘要： An ink storage chamber has a middle wall and a damper wall, which are in parallel to a flow direction of ink and which face each other vertically with a distance therebetween, and a surrounding wall surrounding a circumference of a space between the middle wall and the damper wall. On the middle wall, there is formed a pair of flow regulating ribs projecting toward the damper wall and extending substantially in parallel to the flow direction in a state of having a distance from the damper wall. A space sandwiched by the pair of flow regulating ribs is a main flow region, and spaces between the flow regulating ribs and the surrounding wall is sub-flow regions. A distance between the middle wall and the damper wall in the sub-flow regions is smaller than that in the main flow region. Accordingly, a wasted ink amount during purging can be reduced.
摘要翻译：墨水储存室具有中间壁和阻尼壁，该中间壁和阻尼壁平行于油墨的流动方向并且彼此垂直地彼此面对，并且围绕围绕中间壁和中间壁之间的空间的圆周的周围壁阻尼墙。在中间壁上形成有一对流向调节肋，该阻力壁在与阻尼壁相距一定距离的状态下大致平行于流动方向延伸。由一对流量调节肋夹持的空间是主流动区域，流动调节肋与周围壁之间的空间是副流路区域。在副流动区域中的中间壁和阻尼器壁之间的距离小于主流动区域中的距离。因此，可以减少清洗期间的浪费的墨水量。

摘要： A recording apparatus includes a recording head which discharges an ink onto a recording medium to form an image thereon; a sub tank which is movable together with the recording head and which stores the ink to be supplied to the recording head; an ink supplement section which supplements the sub tank with the ink; and a controller which controls the ink supplement section. The controller controls the ink supplement section to supplement the sub tank with the ink when a residual-ink amount of the ink contained in the sub tank is not more than a threshold value, and the controller is capable of changing the threshold value. Therefore, the number of times of the ink supplement operation is reduced as much as possible by flexibly changing the threshold value depending on the situation while avoiding the discontinuity of the recording operation.
