  • Patent number: 9016842
    Abstract: A liquid container and an apparatus in which the liquid container is mountable are provided, the liquid container and the apparatus enabling the presence or absence of remaining liquid to be checked without the need for a power source and even after the liquid container is removed. The pressure in a communication path is maintained while ink in a containing section is not supplied to the exterior. Thus, the displacement state of a detection valve which is displaced depending on the pressure in the communication path can be maintained even after removal of an ink tank.

  • Patent number: 8770730
    Abstract: A liquid container enables a liquid contained in a liquid containing chamber to be supplied to an exterior through a supply port. The liquid container includes a first channel, a second channel, and a communication path. The first channel is in communication with a first opening which opens into the liquid containing chamber. The second channel is in communication with a second opening which opens into the liquid containing chamber, the second opening being positioned above the first opening in a direction of gravitational force. The communication path allows the first channel and the second channel to communicate with each other outside the liquid containing chamber to permit a flow of the liquid.

  • Patent number: 8205974
    Abstract: An ink tank with a high volume efficiency and a printing apparatus which are capable of completely using up ink stored in the ink tank. A meniscus holding force (Pm1) of a non-compressed portion (22b) of an ink guide member (22) is set higher than an initial ink-storage-portion negative pressure (P1), and lower than a used-up ink-storage-portion negative pressure (P2). In addition, a meniscus holding force (Pm2) caused under compression is set stronger than the used-up ink-storage-portion negative pressure (P2), and weaker than a meniscus holding force (Phf) of a head filter (50).

  • Patent number: 7950790
    Abstract: An ink container usable for recording heads different in flow rate without being affected by a pigment particle concentration of ink held in an ink supply portion is provided. In correspondence with a size of a filter of a recording head used, ink non-conducting areas are provided to a press-contact member, whereby movement of settled ink remaining in the press-contact member is blocked. As a result, common use of the ink container with respect to the recording heads different in flow rate is realized.

  • Patent number: 7832158
    Abstract: An inner area of a framing or framework is divided into a plurality of openings by metal frame bars arranged in a lattice pattern. Particular openings are closed by surface glass panes fitted therein, and the remaining openings by metal plates fitted therein. Spacers 10 softer than the surface glass panes and frame bars and capable of transmitting external forces through the frame bars and surface glass panes are mounted in the openings, between end surfaces extending along sides of the surface glass panes and the frame bars. The spacers not adhering to the surface glass panes are spaced from corners of the surface glass panes.
