Patent number: 10882325Abstract: A liquid supply unit includes a first chamber, a second chamber, an opening/closing member, a biasing member, a pressing member and a flexible film member. The first chamber communicates with a liquid storage container, and the second chamber communicates with a liquid injection head. The opening/closing member changes a posture between a closing posture for closing a communication opening and an opening posture for opening it. The biasing member biases the opening/closing member in a direction toward the closing posture. The pressing member presses the opening/closing member in a direction toward the opening posture. The flexible film member is displaced based on a negative pressure generated in the second chamber. When a pressure receiving portion of the pressing member receives the displacement force from the flexible film member, the pressing member rotates about a pivot point and presses the opening/closing member against a biasing force of the biasing member.Type: GrantFiled: March 25, 2019Date of Patent: January 5, 2021Assignee: KYOCERA Document Solutions Inc.Inventors: Daisuke Eto, Masaaki Maruta, Tomoya Hotani, Yuki Tamura, Ryo Matsuyama

Patent number: 10618298Abstract: A liquid supply unit includes a first chamber, a second chamber, a wall portion, an opening/closing member, a flexible film member and a transmitting member. The wall portion includes a communication opening allowing communication between the first chamber and the second chamber. The opening/closing member changes a posture between a closing posture for closing the communication opening from the second chamber side and an opening posture. The flexible film member is displaced based on a pressure change of the second chamber. The transmitting member transmits a displacement force to the opening/closing member to be the opening posture when the second chamber is set to a negative pressure exceeding a predetermined threshold value, and transmits the displacement force to the opening/closing member to be the closing posture according to a displacement of the flexible film member when the second chamber is pressurized.Type: GrantFiled: March 25, 2019Date of Patent: April 14, 2020Assignee: KYOCERA Document Solutions Inc.Inventors: Yuki Tamura, Masaaki Maruta, Tomoya Hotani, Daisuke Eto, Ryo Matsuyama
