  • Publication number: 20110209335
    Abstract: A predetermined amount of an ink absorber, which is a fiber assembly in which intersections between fibers are not fused together, is charged into a compression and insertion apparatus. A rectangular parallelepiped-shaped insertion block is moved to an upper surface portion of the absorber, and one face of the ink absorber is pushed by a side plate. As such, a part excluding the part of the ink absorber which faces the side plate is compressed and surrounded. In this state, the ink absorber is compressed by the side plate. The ink absorber is inserted into a tank case by making a bottom plate slide, thereby opening the bottom face of the ink absorber and by moving down the insertion block.

  • Publication number: 20030043241
    Abstract: An ink absorbent is contained in the housing of an ink tank for storing ink in the interior thereof, which is provided with a supply port for leading out ink to the outside, and an atmospheric communication port to be communicated with the air outside, and the ink absorbent is formed by fiber material having the surface formed at least by thermoforming. For this ink absorbent, the face which faces the supply port on the inner face of the ink tank is a cut face. With the structure thus arranged, the ink absorbent is prepared to provide cut faces to make the fiber absorbent softer than the thermoformed surface. Then, with the deformability and resiliency of the ink absorbent itself thus obtained, the close contactness with the inner walls of the ink tank is enhanced to prevent not only the ink shortage and ink leakage due to the air pass, but also, prevent the ink absorbent from being deviated when installed.

  • Patent number: 6481825
    Abstract: Disclosed are a recording head cap to be mounted on a liquid-discharging recording head so as to protect an orifice-disposed face of the recording head, and a method and device for mounting the cap on the recording head. The recording head cap has a solid elastic member for pressing the orifice-disposed face when the cap is mounted on the recording head. The solid elastic member has an ultralow sponge hardness, and allows the orifice-disposed face of the recording head to be pressed with a substantially constant and uniform pressing force without being deformed, and to be thereby reliably protected during prolonged storage without causing ink leakage.
