    • A liquid ejection apparatus comprises a liquid bag for containing liquid to be supplied to a liquid ejection head and is adapted to generate negative pressure in the liquid ejection head by a water head difference between the liquid ejection head and the liquid bag. The liquid bag is arranged so that, of two sides of the liquid bag having the largest areas, the side facing in a direction opposite to the direction of gravity is rigidly held at least partly and the other side is freely movable. The liquid bag is provided with a means for detecting an amount of liquid remaining in the liquid bag by reference to a position of the side facing in the direction of gravity, and the detecting means is adapted to move according to the amount of liquid contained in the liquid bag.
    • 液体喷射装置包括用于容纳供应到液体喷射头的液体的液体袋,并且适于在液体喷射头与液体袋之间的水头差产生液体喷射头中的负压。 液袋被布置成使得具有最大面积的液袋的两侧面向与重力方向相反的方向的侧面至少部分地刚性地保持,另一侧可自由移动。 该液体袋具有用于通过参照在重力方向上的一侧的位置来检测残留在液袋中的液体量的装置,并且该检测装置适于根据包含在液袋中的液体的量移动 液体袋。

    • A sheet conveying device includes an endless conveyor belt which has an electrode unit for retaining the sheet by using an electric force and which rotates while retaining the sheet so as to convey the sheet, a first electricity-supplying unit which applies a voltage to the electrode unit while it passes through a predetermined area, a second electricity-supplying unit which is disposed at a predetermined position which is upstream of the predetermined area and downstream of a position where the conveyor belt receives the sheet along a sheet-conveying path, and which applies another voltage to the electrode unit while it passes by the predetermined position, a detecting unit which detects a current or a voltage when the second electricity-supplying unit supplies electricity, and a determining unit which determines the state of the surface of the conveyor belt on the basis of the detected current or voltage.
