摘要： 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.

摘要： A liquid ejection apparatus having a liquid ejection head and a switching device is provided. The switching device includes a first supply passage through which first liquid flows, a second supply passage through which second liquid different from the first liquid flows, a head supply passage, a first ON-OFF valve that selectively opens and closes the first supply passage, a second ON-OFF valve that selectively opens and closes the second supply passage, a rotary cam, and an actuator. The head supply passage extends from a joining point between a downstream end of the first supply passage and a downstream end of the second supply passage to the liquid ejection head. The actuator is driven by the cam in such a manner that the first ON-OFF valve and the second ON-OFF valve are selectively opened and closed. The actuator operates the first and second ON-OFF valves in such a manner that one of the first and second ON-OFF valves becomes open and the other becomes closed.

摘要： A three-dimensional object forming apparatus forms a three-dimensional object by binding powder particles with a curable liquid. The apparatus includes a powder layer forming unit that spreads a powder to a uniform thickness to form a powder layer. A curable liquid ejection head ejects the curable liquid to the powder layer through an ejection nozzle. A sectional data producing device produces sectional data at each of a plurality of cross sections of a desired three-dimensional object according to shape data of the desired three-dimensional object. A cross-sectional member forming section is also included by which cross-sectional members are formed by ejecting the curable liquid to the powder layer from the curable liquid ejection head according to the sectional data and thus binding the powder layer. The cross-sectional member forming section includes a permeation rate controller controlling the permeation rate of the curable liquid to the powder layer.
