摘要： There is provided an inkjet printing head carrying a sub-tank from which accumulated gases can be easily discharged. The inkjet printing head includes a sub-tank which has a movable section constituted by a deformable film sheet, a spring for generating a negative pressure, and a supply/discharge channel for supplying ink and discharging accumulated gases. The sub-tank is intermittently supplied with ink from a main tank and reserving the ink. The supply/discharge channel is provided in a position where it does not interfere with the movable section and the spring, e.g., in a frame of the sub-tank. The supply/discharge channel is preferably formed in an upper part of the sub-tank, e.g., a ceiling section of the sub-tank.

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.
