Document Type and Number:
Japanese Patent JP4379465
Kind Code:
B2
Abstract:
A liquid ejection apparatus includes a liquid ejection head that ejects a liquid and a switching device. The switching device includes a first ON-OFF valve that selectively opens and closes a first supply passage at a position upstream from the joining point, and a second ON-OFF valve that selectively opens and closes a second supply passage at a position upstream from the joining point. When the first ON-OFF valve is open and the second ON-OFF valve is closed, the liquid guide portion divides the first liquid into a first liquid flow proceeding from the first supply passage directly to the head supply passage and a second liquid flow flowing from the first supply passage into the head supply passage after passing the vicinity of the second ON-OFF valve in the second supply passage. When the first ON-OFF valve is closed and the second ON-OFF valve is open, the liquid guide portion divides the second liquid into a third liquid flow proceeding from the second supply passage directly to the head supply passage and a fourth liquid flow flowing from the second supply passage into the head supply passage after passing the vicinity of the first ON-OFF valve in the first supply passage.
