１０が形成されている。2. Description of the Related Art Conventionally, a configuration as shown in FIG. 2 has been known as an example of an inkjet recording head that utilizes airflow. To explain this inkjet recording head, an ink nozzle member 3 made of an insulating material is attached to the outer end of an outer wall 2 of a body member 1, and an ink nozzle member 5 made of an insulating material is attached to the outer end of an inner wall 4 of the body member 1. It is being An air chamber 6 is formed between the outer wall 2 and the inner wall 40 of the body member 1, and the air chamber 6 is formed between the ink nozzle member 3 and the ink nozzle member 5.
An air flow path 7 communicating with the ink nozzle member 5 is formed.
An ink chamber 8 is formed inside. Ink ejection ports 9 are formed at a plurality of locations on the ink nozzle member 5, and air ejection ports 10 are formed in the ink nozzle member 3 opposite to the ink ejection ports 9.

１２が分離独立して設けられている。A common electrode 11 is provided on the outer surface of the ink nozzle member 3 on the outer periphery of the air discharge port 10, and a control electrode 12 is separately and independently provided on the inner surface of the ink nozzle member 5 on the outer periphery of each ink discharge port 9. ing.

気吐出口１０より吐出する。Next, the operation of the above conventional example will be explained. Air is supplied from the air supply source to the air chamber 6 via the air supply path 14,
This air flows out at a constant flow rate as an air layer into the air flow path 7 while making a sharp bend. . On the other hand, the ink chamber 8 is always filled with ink supplied from the ink supply source via the ink supply path 15, and the air pressure sent from the air supply source to the ink supply source causes the ink supply source and the inside of the ink chamber 8 to be filled. A constant pressure is applied to the ink. As a result, the air pressure near the ink ejection port 9 generated by the air flow when the inkjet recording device is not driven and the ink ejection port 9
The pressures of the ink within are approximately equal, and the meniscus of ink generated at the ink ejection port 9 is kept stationary. When a potential difference is provided between the common electrode 11 and the control electrode 12,
Due to the electrostatic force caused by this potential difference, the ink meniscus generated at the ink ejection port 9 is stretched in the direction of the air ejection port 10 . Since the air flow path 7 from the ink discharge port 9 to the air discharge port 10 has a rapid change in pressure gradient caused by the air flow, the meniscus of the ink in the ink discharge port 9 will suddenly change if it is stretched beyond a certain length. The air is accelerated and discharged from the air discharge port 10.

て得ることができる。In addition, in FIG. 2, the ink discharge port 9 is the air discharge port 1.
Although it protrudes toward the 0 side, this has the advantage of effectively exerting the accelerating force of the air flow and concentrating the electric field on the ink meniscus generated at the ink ejection port 9. Such a shape of the ink discharge port 9 can be obtained, for example, by partially etching a photosensitive resin, photosensitive glass, or the like.

で空気流速の均一性を向上させることができる。In an inkjet recording nozzle having a plurality of ejection ports 9 and 10 as shown in FIG.
It is important that the flow velocity or flow rate of the air flow discharged from each air discharge port 10 is uniform between each air discharge port 10, and conventionally, the air flow velocity discharged from each air discharge port 10 is made uniform. Therefore, measures such as those shown in FIG. 3 are taken, for example. That is, assuming that the air discharge ports 1o and the ink discharge ports 9 are arranged at a distance P, there is a gap between the ink nozzle member 3 and the ink nozzle member 5 at approximately the center between the air discharge ports 10 or the ink discharge ports 9. A partition member 100 is provided. In this way, the air outlet 1 is connected to the partition member ioo.
By partitioning the air flow path 7 in the direction in which the ink discharge ports 9 are arranged, the air flow in each air discharge port 10 can be made to flow independently, and the air flow velocity can be made uniform among the 10 air discharge ports. can be improved.
発明が解決しようとする問題点

作するのが雌かしいばかりでなく、組立工程においても
位置合わせの点で精度が要求される。Problems to be Solved by the Invention However, the partition member 100 of the conventional example described above is not only cumbersome to manufacture, but also requires precision in positioning during the assembly process.

度が悪かったり、破損してしまうことが多かった。In particular, when the interval P between the air discharge ports 10 or the ink discharge ports 9 becomes narrower, it is necessary to widen the air flow path @A, so it is required to narrow the width B of the partition member 1000, and the width B of the partition member 1000! r1 narrow and high. It has to be made with an inner cone, and has a shape that requires high rigidity. For example, when the partition member 100 is manufactured by plastic molding, Kt/-i becomes too thin a line, which often results in poor precision or breakage.
