気吐出口１あるいはインク吐出口２近傍で急激な曲りを
生じながら空気吐出口１より空気流が流出している。Conventional configurations and their problems Various systems have been proposed for inkjet recording devices, but here we will explain a system known from Japanese Patent Laid-Open No. 57-120452 as an example. The inkjet recording device described in JP-A-57-120452 is shown. In the figure, air discharge port 1 and ink discharge port 2 are installed on two pages facing each other, and air is created by the gap between the member in which air discharge port 1 is perforated and the member in which ink discharge port 2 is perforated. Air flows through the layer 6 through the annular air chamber 6, and the air flows out from the air outlet 1 while making a sharp bend near the air outlet 1 or the ink outlet 2.

、かつ空気供給源９により送られる空気圧力によりイン
ク溜り８およびインク室７日のインクには一定の圧力が
印加されている。On the other hand, the ink chamber 7 adjacent to the ink discharge port 2 communicates with the ink reservoir 8 and is constantly filled with ink. A constant pressure is applied to.

により生じるインク吐出口２近傍の空気圧力とインク吐
出口２内のインクの圧力がほぼ等しくインク吐出口２に
生じるインクのメニスカスが静止して保たれるようにす
るためである。This is because when the inkjet recording device is not driven, the air pressure near the ink ejection port 2 caused by the air flow and the pressure of the ink inside the ink ejection port 2 are approximately equal, and the meniscus of ink generated at the ink ejection port 2 remains stationary. This is to make it hang down.

は空気流によって急激な圧力勾配の変化が生じているだ
め、インク吐出口２のインクのメニスカスは一定長さ以
上引き伸ばされると急激に加速され空気吐出口１より飛
翔する。An electrode 3 and an electrode 4 are provided on the surface of the air discharge port 1 and the back surface of the ink discharge port 2, respectively. When a potential difference is provided between the electrode 3 and the electrode 4, an electrostatic force generated by this potential difference is generated at the ink discharge port 2. A 3 base ink mesh is stretched in the direction of the air outlet 1. In the space from the ink discharge port 2 to the air discharge port 1, a rapid change in pressure gradient occurs due to the air flow, so when the ink meniscus at the ink discharge port 2 is stretched beyond a certain length, it is rapidly accelerated and the air It flies from the discharge port 1.

。The inkjet recording device shown in FIG. 1 operates according to the configuration and principle described above, but the head portion of the inkjet recording device shown in FIG. 1 has a complicated structure, especially the ink chamber 7 and the annular air chamber 6. It is difficult to machine the shape from an integral member, and this difficulty increases at an accelerating rate as the size of the head portion becomes smaller.

め材料が軟化するといった欠、をがあった。For this reason, conventionally, it has been considered to manufacture an inkjet recording head by laminating a plurality of plates. In this case, materials such as metals such as stainless steel or glass are used,
They have been integrated by bonding with adhesives or by metal bonding, but when adhesives are used, they tend to have poor adhesion and easily peel off, or can be damaged due to differences in thermal expansion coefficients. However, when metal bonding was used, large-scale equipment was required, and the materials softened because they were bonded at high temperatures.

る。Inkjet recording heads with this type of structure contain a resin such as epoxy resin in the 6-beam composite material, so the use of a resin adhesive makes them extremely strong and unaffected by temperature changes. An inkjet recording head can be realized. Since composite materials contain hard materials such as carbon and glass, the material itself has sufficient strength, and since it is a fibrous hard material, it has good workability and can be easily processed into flat plates. Further, the present invention is suitable for cases where the body of the inkjet recording head needs to be made of an insulating material because it uses electric field force, such as the inkjet recording head shown in FIG. A strong inkjet recording head can be easily assembled.
