Document Type and Number:
Japanese Patent JP4099763
Kind Code:
B2
Abstract:
The apparatus has a cap member to internally form a closed space when it makes contact with a nozzle forming face of a liquid ejecting head, a negative pressure generating unit for ejecting a fluid in the closed space and generating negative pressure in the same, and a filter member arranged so that at least a part thereof is positioned in the cap member. On the downstream side of the filter member in the liquid flow direction during suction, a common negative pressure chamber to apply almost uniform negative pressure on almost overall the filter member is formed.
