  • Patent number: 10391778
    Abstract: A liquid cartridge includes: a casing including a liquid chamber; a liquid supply portion; a deformable member; a movable member; and an urging member. An internal pressure of the chamber is reduced as liquid flows out of the chamber. The deformable member protrudes from the casing in a cross direction crossing forward and rearward directions and has an internal space in communication with the chamber. The deformable member has such an elasticity that a dimension thereof in the cross direction becomes smaller as the internal pressure of the chamber is reduced. The movable member includes a detection portion, and a contact portion contacting the deformable member. The contact portion is in contact with the deformable member and disposed at one of positions further forward and further rearward relative to the deformable member. The urging member urges the movable member to move the contact portion toward the deformable member.

  • Patent number: 10384460
    Abstract: A liquid cartridge includes: a casing including a liquid chamber; a liquid supply portion; a deformable member; a movable member; and a support member. The liquid chamber is configured such that an internal pressure of the liquid chamber is reduced as liquid flows out of the liquid chamber. The liquid supply portion allows liquid in the liquid chamber to flow out of the liquid chamber. The deformable member protrudes further upward relative to an upper surface of the casing. The deformable member has an internal space in communication with the liquid chamber. The deformable member is elastically deformable such that a volume of the internal space is reduced as the internal pressure of the liquid chamber is reduced. The movable member includes a detection portion movable in upward and downward directions in accordance with the elastic deformation of the deformable member. The support member supports the movable member.
