    • A thermal ink-jet head of the present invention is so designed as to improve operating frequency by surely trapping foreign substances and reducing the influence of a cross stroke. In the thermal ink-jet head of the present invention, a channel wafer is provided with a nozzle channel, a coupling flow channel, and an ink reservoir. A protective layer and a polyamide layer are formed on a heater wafer. The polyamide layer is provided with pits extending from a heating element up to the coupling flow channel and a bypass pit for coupling the ink reservoir and the coupling flow channel. Foreign substances are trapped at the entry port of the bypass pit and the entry port of the coupling flow channel. The pit controls the growth of the bubble by eating away the front end of the heating element and reducing its rear end. Moreover, the polyamide wall at the end of the pit is made semicircular to suppress the propagation of the pressure toward the coupling flow channel and to reduce the cross stroke by means of the coupling flow channel. The channel pressure wall at the end of the nozzle channel is used to reduce the flow channel resistance.
    • 本发明的热喷墨头被设计成通过可靠地捕获异物并减少横行程的影响来提高操作频率。 在本发明的热喷墨头中,通道晶片设置有喷嘴通道,耦合流动通道和墨水储存器。 在加热器晶片上形成保护层和聚酰胺层。 聚酰胺层设置有从加热元件延伸到耦合流动通道的凹坑和用于联接墨水储存器和耦合流动通道的旁路凹坑。 异物被捕获在旁路通道的入口和耦合流道的进入口。 坑通过消除加热元件的前端并减小其后端来控制气泡的生长。 此外,凹坑末端的聚酰胺壁被制成半圆形,以抑制压力朝向耦合流动通道的传播,并且通过耦合流动通道减少横冲程。 喷嘴通道末端的通道压力壁用于减小流道阻力。

    • The present invention provides an ink jet recording head in which an ink droplet having a small volume that can realize a desired image quality can be ejected onto a recording sheet without making a space between dots in normal printing, and further, in which an ink droplet having a large volume that can afford a sufficient density can be ejected even when thinning-out printing is performed in high-speed printing. An ink jet recording head having two ink supplying openings that introduce ink from an ink tank, an ink chamber that temporarily contains ink introduced from the ink supplying openings and a set of two kinds of first and second ink flowing paths mounted alternately on a flowing path substrate. The first ink flowing path ejects an ink droplet of 7 pl and its ejecting amount is constant. The second ink flowing path selectively ejects one of ink droplets of two volumes, i.e., ink droplets of 7 pl and ink droplets of 30 pl. Specifically, the volume of ink droplets ejected from the second ink flowing path is variable. In the normal printing mode, ink droplets of 7 pl are ejected from the first and second ink flowing paths, while ink droplets of 30 pl are ejected from only the second ink flowing path in the high-speed printing mode.
