【発明の名称】インクジェットプリントヘッド、その製造方法及びインク吐出方法
Document Type and Number:
Japanese Patent JP3382932
Kind Code:
B2
Abstract:
A bubble-jet type ink-jet printhead, a manufacturing method thereof, and a method of ejecting ink are provided. In the printhead, a manifold (150) supplying ink, a hemispherical ink chamber (200), and an ink channel (210) for connecting the manifold with the ink chamber are integrally formed on the substrate. A nozzle plate (110) on the substrate (100) having a nozzle, and a heater (120) formed in an annular shape and centered around the nozzle are integrated without a complex process such as bonding. Thus, this simplifies the manufacturing process and facilitates high volume production. Furthermore, according to the ink ejection method, a doughnut-shaped bubble (310) is formed to eject ink, thereby preventing a back flow of ink as well as formation of satellite droplets which may degrade image resolution.
