  • Patent number: 10792924
    Abstract: A liquid supplying system includes a cartridge having a first storage chamber, a tube to which the cartridge is connectable, a tank having a second storage chamber, and a detector. The liquid stored in the first storage chamber of the cartridge connected to the tube is introduced through an opening of the tube. The liquid introduced through the opening flows through a liquid passage of the tube. The tank includes an inlet port for introducing the liquid flowing through the liquid passage into the second storage chamber. The detector detects whether a level of liquid in the second storage chamber is at a predetermined position that is below the opening and above the inlet port. The second storage chamber has a horizontal cross-sectional area greater than a horizontal cross-sectional area of the liquid passage in a region above the predetermined position and below the opening in a vertical direction.

  • Patent number: 10780704
    Abstract: A print head assembly for an ink-jet printer operable with a continuous ink supply system is disclosed, with an ink compartment, a foam insert, an ink fill port, and a spacer. The ink fill port receives ink fed from an external supply and to be printed by the print head assembly. The ink compartment stores the ink to be printed. The foam insert is in the ink compartment and takes up the ink to be stored. The spacer extends into the ink compartment, provides for the formation of a clearance between the foam insert and the ink fill port and surrounds the ink fill port either completely or with one or more gaps having a gap width. The gap width of none of the gaps presents an aperture angle of more than 25% of 36° with respect to a center of the ink fill port.

  • Patent number: 10773525
    Abstract: A liquid cartridge configured to be inserted into a cartridge-attachment section in an insertion direction includes a casing, and a lever supported by the casing. The lever is pivotable about a pivot axis between a first position and a second position. The lever includes a light-blocking portion configured to block or attenuate light traveling in a widthwise direction crossing the insertion direction and a gravitational direction, and a force-receiving portion positioned closer to a front wall of the casing than the light-blocking portion is to the front wall in the insertion direction. The light-blocking portion is positioned lower at the second position than at the first position. The pivot axis is positioned frontward of the light-blocking portion and rearward of the force-receiving portion in the insertion direction. The lever pivots from the second position to the first position upon application of an external force to the force-receiving portion.
