Abstract: An inkjet type printer having a recording head is disclosed. The printer includes a cap and a raising and lowering unit. The raising and lowering unit moves the cap between a sealing position at which the cap contacts the recording head and a retreat position at which the cap is separated from the recording head. The raising and lowering unit includes a selection cam, a cleaning mechanism, and a lift lever. The cleaning mechanism supports the cap and the selection cam, and is movable along the moving direction of the cap. The distal end of the lift lever is engaged with the selection cam at a position near the outer circumference of the selection cam, and the proximal end of the lift lever is coupled to a pressure adjustment shaft. The selection cam is raised or lowered while being rotated about the distal end of the lift lever, so that the cap is moved between the sealing position and the retreat position.

The valve unit includes a valve body, a first passage defining member, a second passage defining member, a first passage, and a second passage. The first passage defining member and the second passage defining member are located at opposite sides of the valve body. The first passage is defined between the valve body and the first passage defining member. The second passage is defined between the valve body and the second passage defining member. The valve body has a first passage valve that closes the first passage when the valve body moves in the first direction and a second passage valve that closes the second passage when the valve body moves in the second direction.

Abstract: An ink cartridge for an ink jet recording device, includes: a container having an ink supply port; at least two ink chambers partitioned in the container, one being located substantially in an upper section and the other being located substantially in a lower section; an ink suction passage connecting a bottom region of the lower section ink chamber to a bottom region of the upper section ink chamber; and a negative pressure generating mechanism provided to a flow passage connecting the upper section ink chamber to the ink supply port.

Abstract: In an ink cartridge, a negative pressure generating mechanism is disposed between an ink storage region and an ink supply port, and has a wall surface having two through-holes for ink flow, and a valve member contacted with and separated from the through-hole by receiving a pressure in an ink supply port side. Ink flowing via the through-hole is supplied via the through-hole to the ink supply port.

Such an intermediate wall 301 partitioning the ink tank chamber 11 into two space parts 11a and 11b placed side by side in an ink injection direction is disposed in the ink tank chamber 11 and is formed with a through part 301a through which ink can be injected.

Abstract: A fluid ejection apparatus that ejects fluid from an ejection nozzle in an ejection head includes a fluid receiver that has a concave portion for accommodating the ejected fluid and defines a closed space around the ejection nozzle when the concave portion contacts the ejection head. Suction pumps suck the fluid in the concave portion through suction ports in the concave portion. A fluid suction unit sucks the fluid in the ejection head through the ejection nozzle by operating the suction pumps such that the concave portion contacts the ejection head. An air suction unit sucks the air and the fluid in the concave portion of the fluid receiver after completion of suction of the fluid in the ejection head, by allowing at least one suction pump to reverse the air flow in collaboration with the operation of at least one other suction pump.
