A fluid ejection device includes a fluid ejection unit that ejects a fluid onto an ejection target; a main chassis case that includes a platen disposed in a area for ejecting the fluid by the fluid ejection unit; a container case for containing a pack, the pack containing a fluid for ejection, wherein the container case is pivotably attached to the main chassis case and openable by rotation about a rotation shaft; and a delivery tube that delivers the fluid from the pack to the fluid ejection unit.

Installing fluid container in fluid ejection device

A fluid ejection device ejecting a fluid, the fluid ejection device includes: a fluid container; a fluid ejection unit; a delivery needle; a guard cover; and a guide. The fluid container includes a container portion and a withdrawal portion. The container portion contains a fluid for ejection, and the withdrawal portion allows withdrawal of the fluid contained in the container portion. The fluid ejection unit ejects a fluid onto an ejection target. The delivery needle provides a flow passage which communicates with the fluid ejection unit. The guard cover projects over the delivery needle. The guide mates with the fluid container, and then slidably guides the withdrawal portion toward a locking position where the delivery needle sticks through the withdrawal portion.

A fluid ejection device ejecting a fluid, the fluid ejection device includes: a fluid ejection unit, a main chassis case, a fluid-containing pack, and a container case. The fluid ejection unit ejects a fluid onto an ejection target. The main chassis case houses the fluid ejection unit. The fluid-containing pack contains a fluid for ejection. The container case houses the fluid-containing pack. The container case is pivotably attached to the main chassis case and openable by rotation about a rotation shaft. The fluid ejection device further comprises a fluid passage, including a delivery tube with a bent section, in which fluid flows from the fluid-containing tank to the fluid ejection unit through the container case. The shape of the bent section changes by the opening and closing of the container case.

A paper feeding device having a paper cassette configured to support a plurality of the papers in a stacked manner, a separating bevel having an inclined plane inclined at a predetermined angle with respect to a supporting surface of the paper cassette and configured to separate the paper coming into abutment with the inclined plane, a pickup roller configured to feed the paper toward the separating bevel by coming into contact with the topmost paper from among the papers supported by the paper cassette and being rotated thereon, and a space forming unit configured to form a space S for letting part of the paper to escape in the feeding direction on part of the inclined plane in the area opposing the pickup roller in the feeding direction is employed.

Sheet material feeding device and recording apparatus

A fluid ejection device ejecting a fluid, the fluid ejection device includes: a fluid ejection unit; a fluid container; a delivery needle; and a guard cover. The fluid ejection unit ejects a fluid onto an ejection target. The fluid container includes a container portion and a withdrawal portion. The container portion contains a fluid for ejection, and the withdrawal portion allows withdrawal of the fluid contained in the container portion. The delivery needle sticks through the withdrawal portion to provide a flow passage which communicates with the fluid ejection unit. The guard cover projects over the delivery needle to prevent the withdrawal portion from approaching the delivery needle from a direction intersecting a center axis of the delivery needle.

A fluid ejection device ejecting a fluid, the fluid ejection device includes: a fluid ejection unit; a main chassis case; a fluid-containing pack; a container case; and a plurality of holders. The fluid ejection unit ejects a fluid onto an ejection target. The main chassis case houses the fluid ejection unit. The fluid-containing pack contains a fluid for ejection. The container case houses the fluid-containing pack. The plurality of holders is disposed inside the container case. Each of a plurality of holders includes an incline panel that inclines toward the inside base plane, and the fluid-containing pack rests on the incline panel.

To easily form an excellent connection state between a terminal of an information storage medium in an ink cartridge and a contact of a carriage and, additionally, to reliably maintain the excellent connection state. A carriage includes an ink-cartridge receiving chamber for receiving an ink cartridge, an electronic substrate having a contact for connecting with an information storage medium of the ink cartridge, a mounting-position regulating portion for regulating the position of the ink cartridge with respect to a contact by regulating the mounting position of the ink cartridge in the ink-cartridge receiving chamber, and a head unit having a recording head. The mounting-position regulating portion is independent of the ink-cartridge receiving chamber so as to be freely removable and attachable with respect to the ink-cartridge receiving chamber in a state in which the electronic substrate is attached.

Carriage and liquid ejecting apparatus

In a platen gap adjustment device, a stable area detection device for a platen gap formed between ahead and an upper surface of a platen, wherein the carriage guide shaft is moved relatively to the platen so that the platen gap is adjusted by driving the drive motor to rotate the gap adjuster cam, the gap adjuster cam is configured so as to provide a plurality of stable areas and a plurality transition areas; and wherein a stable area detection sensor is provided so as to face to a rotational member which rotates synchronously with the gap adjuster cam, and a detection object in correspondence with the stable areas of the platen gap is provided on the rotational member.
