摘要： A liquid ejecting head includes a liquid discharge unit with a pressure generating chamber group which communicates with a nozzle disposed on a nozzle surface and is formed from pressure generating chambers disposed in a first direction, and a case member which communicates with the pressure generating chamber group and holds a liquid. The case member has a liquid inlet on the side opposite to the liquid discharge direction and at a position between the pressure generating chambers at both ends in the first direction. First and second liquid discharge units are arranged at positions where the first directions of the first and second liquid discharge units are parallel to each other in a second direction that is orthogonal to the first direction, and positions of the liquid inlets of the case member respectively corresponding to the first and second liquid discharge units do not overlap in the second direction.

摘要： A liquid ejecting head includes a nozzle plate including a nozzle opening provided on a first surface of a flow path member with a flow path formed therein, and a protective member including a flexible portion that seals a portion of the flow path provided on the first surface of the flow path member. A position of a portion of the flow path member onto which the nozzle plate is attached and a position of a portion of the flow path member onto which the protective member is attached are different from one another in a discharge direction of a liquid.

摘要： A wall-shaped enclosure that forms a space which can accommodate a head chip is formed in a projecting manner at a lower end of a lower case member. Since a cylindrical thick part is formed at the lower end of the lower case member, the lower case member is unlikely to be bent, particularly around the wall-shaped enclosure and a part where the wall-shaped enclosure is disposed. The head chip that is disposed in the space of the lower case member which is unlikely to be bent is unlikely to be subjected to an external force, and the cover member absorbs torsion generated between the head chip and the lower case member so that the head chip is even more unlikely to be subjected to the external force.
摘要翻译：形成可容纳头部芯片的空间的壁形外壳以突出的方式形成在下壳体的下端。由于在下壳体的下端部形成有圆筒状的厚壁部，所以下壳部件不可能弯曲，特别是围绕壁状的外壳和壁状的外壳的一部分。设置在下壳体的不易弯曲的空间的头部芯片不太可能受到外力，并且盖构件吸收头部芯片和下壳体部件之间产生的扭转，使得头部芯片更不可能受到外力的影响。

摘要： A liquid storage unit for collecting a liquid supplied to an ejecting head is provided. The liquid is supplied to a plurality of ejecting heads via a pressure regulating valve, and the liquid is suctioned from the plurality of ejecting heads by a circulation pump, and then is discharged to the liquid storage unit. In this way, since the liquid is suctioned from each of the ejecting heads, the passage resistance is decreased, so that the ink can be appropriately circulated. In addition, since the ejecting head is supplied with the liquid at an appropriate pressure from the liquid storage unit via the pressure adjusting valve, the liquid can be appropriately ejected.
摘要翻译：提供了用于收集供应到喷射头的液体的液体存储单元。液体通过压力调节阀供给到多个喷射头，液体通过循环泵从多个喷射头吸入，然后被排出到液体存储单元。以这种方式，由于从每个喷射头吸入液体，所以通过阻力降低，使得油墨可以适当地循环。此外，由于喷射头经由压力调节阀从液体存储单元以适当的压力供应液体，所以可以适当地喷射液体。
