Patent number: 10029474Abstract: A liquid storage unit including a first liquid storage chamber having a constant volume and being capable of holding liquid supplied from a liquid tank; a second liquid storage chamber communicating with the first liquid storage chamber; a pressure control chamber configured to change a pressure of the pressure control chamber through actuation of a pressure control unit; and an elastic member being configured to tightly partition the second liquid storage chamber and the pressure control chamber from each other and being deformable so as to increase and decrease a volume of the second liquid storage chamber in accordance with the pressure of the pressure control chamber. The elastic member is capable of removing bubbles in the first liquid storage chamber by increasing and decreasing the volume of the second liquid storage chamber through the deformation.Type: GrantFiled: May 18, 2015Date of Patent: July 24, 2018Assignee: CANON KABUSHIKI KAISHAInventors: Hitoshi Takada, Yasuo Kotaki, Tetsuya Ohashi, Ryoji Inoue, Takatoshi Kitagawa, Hironori Murakami, Takeho Miyashita, Hiroki Hayashi, Hironori Fukuchi, Norihiro Ikebe, Takashi Fukushima
