Abstract
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.
