[0023] A preferred embodiment according to the first embodiment of the present invention will be described below with reference to the accompanying drawings.

[0024] figure 1 is a perspective view showing the appearance of the ink jet print head according to the first embodiment.

[0025] Figure 2 is along the figure 1 A cross-sectional view taken along the line II-II. The inkjet print head 1 has a head body 70 and a bottom block 71 . The head body 70 is shaped like a flat rectangle extending in the main scanning direction for ejecting ink onto paper. The bottom block 71 is disposed above the head body 70 and includes the ink pool 3 constituting a flow path for supplying ink to the head body 70 .

[0026] The head body 70 includes one flow path unit 4 , and a plurality of actuator units 21 . An ink flow path is formed in the flow path unit 4 . The plurality of actuator units 21 are bonded to the upper surface of the flow path unit 4 . The flow path unit 4 and the actua...

[0060] A second embodiment of the present invention will be described below with reference to the drawings.

[0061] The head body 70A according to the second embodiment corresponds to the head body 70 according to the first embodiment. The second embodiment is basically the same as the first embodiment except for the cross-sectional structure of the head body 70A in the second embodiment. Therefore, only the cross-sectional structure of the head body 70A in the second embodiment will be described.

[0062] Figure 10 is along Figure 5 Sectional view taken along midline VI-VI. Figure 10 A pressure chamber 10a belonging to the first pressure chamber row 11a is shown in . as from Figure 10 Clearly, the nozzle 8 is connected to the manifold 5aA through the pressure chamber 10 (10a) and the slit 12. In this way, an individual ink flow path 32A for guiding ink from the outlet of the manifold 5aA through the slit 12 and the pressure chamber 10 to the nozzle 8 is formed in t...

Abstract

An inkjet printing head including: a common ink chamber having an outlet; and an individual ink flow path having a pressure chamber and leads ink from the outlet of the common ink chamber to a nozzle through the pressure chamber, wherein the common ink chamber and the individual ink flow path are formed of a plurality of thin plate members having holes formed thereon, the thin plate members being laminated and fixed onto one another by metal-metal junction, and wherein sectional area of the common ink chamber along a planar direction of the thin plate members is configured to be smaller at an end portion where the outlet is provided than at a central portion in a direction of thickness of the plurality of thin plate members.

Description

technical field [0001] The present invention relates to an inkjet printhead for ejecting ink onto a recording medium for printing. Background technique [0002] The inkjet printer includes at least one inkjet printing head, and the inkjet printing head is provided with nozzles, so that the ink can be ejected from the nozzles to print on the printing medium. In such an inkjet printhead, it is necessary to form a complicated and precise ink flow path in the inkjet printhead. Therefore, the inkjet printhead is formed by laminating thin-plate-like etched plates. For secure lamination and bonding of etched plates to one another, it is conceivable to use adhesives, such as epoxy resin adhesives, polyimide adhesives or acrylic adhesives, for example. However, when the amount of adhesive applied is large, the adhesive may flow into the ink flow path formed inside the inkjet print head. As a result, the ink flow path may be narrowed or blocked by the adhesive. It has therefore be...
