摘要：
PROBLEM TO BE SOLVED: To provide a liquid droplet delivering head which can stably deliver even a high-viscosity liquid.
SOLUTION: A delivering liquid is pressurized and supplied to a cavity 23 which communicates with a nozzle 22, and at the same time, the nozzle 22 is can be blocked with a pin 24 and the pin 24 is can be isolated from and contacted with the nozzle 22 by an actuator 25. The actuator 25 is controlled by a controller 12. By the constitution, the delivering liquid supplied under pressure is delivered as liquid droplets from the nozzle 22 only while the pin 24 is isolated from the nozzle 22. Moreover, the actuator 25 can be reduced in size by constituting the actuator 25 with a piezoelectric element. In consequence, the integration level of the nozzles 22 is enhanced, enabling delivering of more minute liquid droplets. In addition, the cavity 23 is formed to communicate with a plurality of the nozzles 22 in common, eliminating the need of forming the cavity for every nozzle as conventionally. Constitution becomes easy and costs can be reduced.

要解决的问题：提供一种甚至可以稳定地输送高粘度液体的液滴输送头。
解决方案：输送液体被加压并供应到与喷嘴22连通的腔23，同时喷嘴22可以用销24阻挡，并且销24可以与销24隔离， 通过致动器25与喷嘴22接触。致动器25由控制器12控制。通过这种结构，只有当销24与喷嘴22隔离时，在压力下供应的输送液体才从喷嘴22以液滴的形式被输送 此外，通过用压电元件构成致动器25，致动器25的尺寸可以减小。 因此，增强了喷嘴22的集成度，使得能够输送更多的微小液滴。 此外，空腔23形成为与多个喷嘴22共同连通，从而消除了如常规地为每个喷嘴形成空腔的需要。 宪法变得容易，成本可以降低。 版权所有（C）2011，JPO＆INPIT
