いインクジェット記録装置を提供するところにある。However, the thermal inkjet recording device introduced in the above-mentioned literature does not provide a protrusion on the ejection port plate in order to join the substrate on which the heating element of the print head section is formed and the ejection date plate on which the ejection port is formed with a gap. The protrusions maintain a gap and are fixed with adhesive, which not only causes the adhesive to deteriorate over time, but also makes it difficult to form the protrusions on the discharge port plate and takes a long time to manufacture using adhesive. have Therefore, the present invention is intended to solve these problems.
The objective is to provide an inkjet recording device that does not deteriorate over time and has low manufacturing costs.

６が吐出口仮押え板１７で押さえられ固定される。The operation of each part will be briefly explained with reference to FIGS. 2 and 3. In FIG. 2, a substrate 14 has a recording liquid supply hole 21 in the center and is joined to a mounting base 13, and a gap plate 15 and a discharge date plate 16 are fixed on the substrate 14. The recording liquid supplied from the recording liquid supply pipe 12 shown in FIG. 3 passes through the recording liquid supply hole 21 and is supplied to the gap between the substrate 14 and the nozzle plate 160. Electric power is intermittently supplied to the heating element 20 through the electrode 19 to generate Joule heat, and the recording liquid in contact with the surface of the heating element 200 undergoes rapid film boiling, causing a pressure change that causes recording droplets to be ejected from the ejection port 22. 24 is what is discharged. The discharge port temporary holding plate 17 is a plate spring, and is bent so as to press the discharge port plate 16 with a plurality of minute parts, and the top plate 1
By fixing the board 14.8 to the mounting base 13 to which the board 14 is joined with the screws 23, the board 14. Gear lug plate 15. Discharge plate 1
6 is pressed and fixed by the discharge port temporary holding plate 17.
上記構成によれば、記録ヘッド１０組み立てに接着剤を

い基板１４と吐出口板１６０間隙が得られる。According to the above configuration, there is no need to use adhesive to assemble the recording head 10, and the assembly can be performed in a short time. Further, by pressing the discharge port plate 16 with a plurality of minute parts, the discharge port plate 16 can be fixed without applying excessive stress to the discharge port plate 16. Furthermore, there is no need to provide a protrusion on the discharge port plate 16, making it easy to create the discharge port plate 16, and the gap plate 15
As a result, a more accurate gap between the substrate 14 and the ejection port plate 160 can be obtained than when the ejection port plate 16 is provided with a protrusion.

る。Furthermore, by using an elastic material for the gap plate 15,
Minute dust, substrate 14. The unevenness of the discharge port plate 16 is absorbed by the elasticity of the gear plate 150, and the base plate 14 and the discharge date plate 16 are
Does not affect zero gap accuracy. Moreover, the gap plate 15 and the substrate 14. The gap between the gap plate 15 and the discharge port plate 160 is almost eliminated, and leakage of recording liquid can be ignored. Furthermore, the friction between the gap plate 15 and the substrate 14, and between the gap plate 15 and the discharge port plate 16 increases, and the discharge port temporary holding plate 17 is caused by the substrate 14, the gear plate 15, and so on. Even if the force for pressing the ejection port plate 16 is weak, the mutual positional deviation between the substrate 15 and the ejection port plate 16 is extremely unlikely, and stable recording liquid ejection can be obtained over a long period of time.

である。As a material for the gap plate 15 having elasticity, a rubber-based or resin-based sheet can be considered, but the suitable thickness of the gap plate is 25 μm to 100 μm, and a material that can obtain appropriate elasticity at this thickness is as follows. Resin-based sheets, especially polyimide films and polysulfone films, are suitable as they are durable even when in contact with recording liquid.
