Embodiment Construction

[0016] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings.

[0017] figure 1 It is an external perspective view of an electronic equipment device 100 equipped with an inkjet recording device 10 which is an example of a liquid ejection device according to the present embodiment.

[0018] The inkjet recording device 10 is a device that transports the recording medium S in the vertical direction V to perform recording. Here, the conveying direction of the recording medium S may be a direction having an angle with the vertical direction V. The figure shows the vertical direction V and the horizontal direction H.

[0019] in figure 1 Among them, the electronic equipment device 100 includes an inkjet recording device 10 and a display 20. In this embodiment, the inkjet recording device 10 is arranged on the back of the display 20 in order to save space.

[0020] The inkjet recording device 10 discharges the recording medium S fr...

Abstract

The invention provides a liquid ejection head and a liquid ejection apparatus. An ink introducing port is provided on the upstream side of the center of a row of pressure chambers in the direction of gravity g, the pressure due to ink introduction is applied to a region where the influence by the head is small.

Description

[0001] The present invention claims the priority of application No. 2010-032151 filed in Japan on February 17, 2010, and the entire content thereof is cited here. Technical field [0002] The present invention relates to a liquid ejecting head and a liquid ejecting device. Background technique [0003] As a typical example of the liquid ejection head, as disclosed in Japanese Patent Application Laid-Open No. 2000-62164, ink is supplied from the ink introduction port to a plurality of pressure chambers via a manifold, that is, a water tank. The water tank is a common ink chamber that supplies ink to each pressure chamber, and is formed to extend long along the row direction of the pressure chambers. In addition, as disclosed in Japanese Patent Laid-Open No. 10-272770, the inkjet recording head is arranged at an angle of 45 degrees or vertically in a liquid ejection device, that is, an inkjet recording device. [0004] However, in the liquid ejection device, if the nozzle row directi...
