摘要： A liquid container has a movable member which defines a liquid containing space and which is displaced as the liquid is supplied, a valve for allowing a gas to be introduced into the containing space from the outside and for preventing the liquid from being extracted from the containing space to the outside, and an introduction channel for coupling the valve and the containing space to guide the introduced gas into the containing space. An intake port of the introduction channel located on the containing space side is positioned in an upper part of the containing space in an orientation in use. A negative pressure is kept substantially constant to consume the liquid completely. Since the air introduction for keeping the negative pressure at an adequate value is carried out in a region in a gaseous phase in the container, no leakage of ink occurs, and air is reliably introduced.

摘要： In a structure of an ink tank having a deformable sheet that constitutes the tank and a spring for imparting a negative pressure, unstableness of the negative pressure attributable to the deformation of the sheet as a result of ink consumption is prevented. For this purpose, a plate-like member is joined to a top section of the sheet formed in a convex shape, and the spring for generating the negative pressure in the tank is mounted to the same member. This makes it possible to maintain a high volume ratio of the ink tank and to achieve stableness of the negative pressure by adequately regulating the deformation of the sheet when the sheet is displaced in the direction of retracting toward the interior of the tank as a result of a reduction of the amount of ink in the tank.

摘要： A liquid (ink) supply system having a closed structure with respect to an inkjet recording head is configured such that a gas hindering a recording operation and a liquid supply operation can be rapidly and smoothly eliminated from a liquid supply system without involving any complication in structure. An ink tank (10) and a liquid chamber (50) for leading ink supplied to the recording head (20) are brought into fluid communication via two communication channels (53 and 54). Thus, in the state where the gas exists inside the liquid chamber, the ink is moved from the ink tank (10) via one communication channel (53), while the gas is transferred to the ink tank (10) via the other communication channel (54).

摘要： In the printing apparatus, the printing region, the paper-conveying roller region and the ink (printing agent) region are arranged on a straight line generally parallel to the plane containing the printing region. Thereby, it is possible to accommodate the increase in the printing region or the ink (printing agent) region in an area on the straight line. Accordingly, the reduction of the running cost is realized by a printing agent container of a large capacity, while enabling the high-speed printing by ensuring the large printing region surface in the thin and small-sized printing apparatus.

摘要： In an ink storing container, movable members are properly constructed by molding sheet material into a convex form and are properly welded to a frame. The ink storing container is provided with an air passage section in which an ink meniscus is formed correspondingly to pressure relative to the atmosphere and through which the interior of an ink storing space is in communication with the atmosphere via an air path having a predetermined length. Thus, when negative pressure in the storing space increases, an air is introduced into the space via the air passage section. On the other hand, when the gas in the ink storing section expands to push the ink in the storing space, the ink can be kept in the path. As a result, the interior of the ink storing space is maintained at appropriate negative pressure for ink supply.
