[0031] figure 1 It is a partial configuration diagram of the liquid ejection device 10 according to the first embodiment of the present invention. The liquid ejection device 10 of the present embodiment is an inkjet printing device that ejects ink as an example of a liquid onto a medium 11 such as printing paper. figure 1 The illustrated liquid ejection device 10 includes a control device 12 , a transport mechanism 15 , a carriage 18 , a liquid ejection head 20 , and a pump 16 . A liquid container (cartridge) 14 for storing ink is attached to the liquid ejection device 10 . In this embodiment, four color inks I of cyan (C), magenta (M), yellow (Y), and black (K) are stored in the liquid container 14 .

[0032] The control device 12 comprehensively controls each element of the liquid ejection device 10 . The conveying mechanism 15 conveys the medium 11 in the Y direction under the control of the control device 12 . The pump 16 is an air supply device that supplies air A to ...

[0077] A second embodiment of the present invention will be described. In addition, the symbols used in the description of the first embodiment are attached to the elements whose action and function are the same as those of the first embodiment in the second embodiment, and each detailed description is appropriately omitted. Figure 7 is a cross-sectional view showing the structure of the liquid ejection head 20 in the second embodiment, and corresponds to Figure 5 Sectional view of VII-VII. In the second embodiment, the flow channel member 30 is exemplified. The flow channel member 30 is configured not only to allow the elastic member 60 to absorb accumulated tolerances and the like, but also to function as an actuator for driving the valve body and the like. .

Abstract

The present invention relates to a flow path structure, a method of manufacturing the same, a liquid ejection head, and a liquid ejection device. The present invention improves the positioning accuracy of a plurality of flow path members disposed between components. The flow path structure of the present invention includes: a first member having a first surface; a second member having a second surface; a plurality of flow path members disposed between the first surface and the second surface, and having a flow passage; and an elastic member laminated on the plurality of flow path members between the first surface and the second surface and having a flow passage.

Description

technical field [0001] The present invention relates to a flow channel structure having flow channels through which ink, air, etc. flow, a method for manufacturing the flow channel structure, a liquid ejection head using the flow channel structure, and a liquid ejection device. Background technique [0002] A liquid ejection device that ejects liquid such as ink from a nozzle includes, for example, a flow path structure in which a plurality of flow path members are laminated to form a flow path through which the liquid flows, as described in Patent Document 1. In the flow channel structure of Patent Document 1, a plurality of flow channel members such as a first flow channel member, a second flow channel member, and a pressure chamber forming member are laminated one by one in the same direction. [0003] However, when a plurality of flow channel members are provided between two members, there is a possibility that the positioning accuracy of each flow channel member may be ...
