Description

【０００８】
【課題を解決するための手段】
上記目的を達成するために本発明は、インクの流体力学的作用によりヘッドの基板の貫通口付近に流れを作り、共通液室壁面に付着した泡を剥がしやすいように、または泡が付着しにくいようにしたものであり、その構成は、インクを吐出するために用いられるエネルギーを発生する複数の電気熱変換素子が配列され、該複数の電気熱変換素子の配列方向に沿って延在する貫通口からなるインク供給口を有する基板と、インクを吐出する複数のインク吐出口を前記電気熱変換素子の上方に備えた吐出口プレートと、を備え、前記吐出口プレートが前記基板上に接合されることで、前記基板と前記吐出口プレートとの間に前記複数の吐出口と前記インク供給口とに連通するインク流路が形成されているインクジェットプリントヘッドにおいて、前記吐出口プレートの前記インク供給口投影領域に、前記インク供給口側が開放された前記インク流路の流体抵抗手段を有するものである。[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention makes a flow near the through hole of the substrate of the head by the hydrodynamic action of the ink so that the bubbles attached to the common liquid chamber wall surface are easily peeled off, or the bubbles are hardly attached as it is obtained by the, its configuration, a plurality of electrothermal conversion element array for generating energy used for discharging ink, or extending along the arrangement direction of the plurality of electrothermal transducers a substrate having an ink supply port comprising a through-hole, provided with a discharge port plate which a plurality of ink discharge ports provided above the electrothermal transducers for ejecting ink, or a, to said discharge port plate on the substrate By being joined, in the ink jet print head in which an ink flow path communicating with the plurality of discharge ports and the ink supply port is formed between the substrate and the discharge port plate, Said ink supply port projecting area of the serial discharge port plate, said ink supply port side is to have a fluid resistance means open said ink channel.
