Abstract: A liquid container includes a lever having one end supported to an outer wall of a housing containing a liquid therein and the other end as a free end, the lever being elastically deformable. The liquid container further includes a projection provided in an area of the housing which is opposite to and away from the supported one end of the lever, the projection covering at least a part of a space between the free end of the lever and the housing in the above area. By virtue of the projection, the lever can be protected against accidental external forces. In a cap-equipped liquid container, a straight line connecting a projected end of the projection of the liquid container and a distal end of a tab of a cap is set to cross a movable range of the lever provided on the liquid container in which the lever is allowed to angularly move with elastic deformation thereof.

Abstract: An ink jet cartridge including a case, in which the bottom portion where an ink jet recording head is disposed projects, and a lid for covering the top surface thereof. In an ink containing chamber defined by the these case and the lid, there is provided an absorber. The lid is configured so that ribs provided directly over the projecting bottom are higher than the other ribs, and so that the lid can be used for different types of cartridge. In a black cartridge, the pertinent ribs perform the function of effectively bringing the absorber into pressure contact with an ink introducing section. In a color cartridge, the pertinent ribs perform the function of restraining the height of the top surface of the absorber disposed on the projecting bottom portion to a position lower than that of the top surface of each of the other absorbers.

Abstract: A digital signal transmission circuit which uses a MOS type LSI (1) or the like having, e.g., an FET (3), and which is so configured that a step waveform produced from a transmission terminal such as an FET output terminal (4) reaches a reception terminal such as an FET input terminal (5) via a signal line. A signal line is added with a resistance component in a distributed manner at part or whole thereof. The resistance component may have set therein in advance a voltage drop due to the transmission loss of a signal line so that the amplitude of a transmission signal is damped at a reception terminal to a specified percentage of that at a transmission terminal. For example, it is preferable that the wire and wire length of a signal line be properly selected to serve as an addition to a resistance component so that a voltage drop is almost equal to ½ the amplitude of a transmission signal.

Abstract: An ink jet cartridge and an ink tank are provided which can prevent an inappropriate ink tank from being mounted on the mounting portion of the tank holder. To this end, the tank holder has a tank mounting portion on which the ink tank is mounted. The tank mounting portion has a raised portion and the ink tank is formed with a notched portion. Moving the ink tank in a roughly pivotal motion by engaging the notched portion over the raised portion can connect the ink supply ports to the ink introduction portions. Now the mounting process is complete.
