摘要： Ink droplet sensing apparatus for use in an ink jet printer for detecting errors resulting from the omission or misplacement or from the reduced size of a printed dot. In one embodiment the apparatus includes a membrane (14) having a metallic coating thereon which membrane (14) is placed over one side of an electrode member (10) having an uneven surface. Voltage is applied to the electrode member (10) and the metallic coating and ink droplets (20) impinging on the membrane (14) momentarily deflect the membrane and cause a change of capacitance which in turn causes a voltage change at the electrode member (10). The voltage change is coupled through a capacitor (22) and an amplifier (24) to recognition logic for evaluation of the signals.

摘要： Ink jet print head (10) and method of controlling the flight path of ink droplets ejected therefrom. The print head includes a body portion (12) through which at least one ink conduit (34) is arranged to extend, ending in a nozzle (46) through which ink droplets (48) are ejected. The body portion incorporates a resilient portion (14) which can be deformed so as to bring about a tilting movement of the nozzle thereby to change the flight path of the ejected droplets. The tilting of the nozzle and the control of the flight path of the droplets is achieved in a simple manner without the requirement of complex deflecting electrodes positioned externally of the head between the nozzle and the record medium.
摘要翻译：喷墨打印头（10）以及控制从其喷出的墨滴的飞行路径的方法。打印头包括主体部分（12），至少一个墨水导管（34）通过该主体部分延伸，终止于喷嘴（46），喷嘴通过喷嘴喷射墨滴（48）。主体部分包括可变形的弹性部分（14），以便引起喷嘴的倾斜运动，从而改变喷射的液滴的飞行路径。喷嘴的倾斜和液滴的飞行路径的控制是以简单的方式实现的，而不需要位于喷嘴和记录介质之间的头部外部的复杂的偏转电极。
