摘要： The water drop removing apparatus for a camera lens assembly is arranged to automatically wipe off water drops or the like attached on the front face of the lens assembly to make field shooting in rainy or snowy weather easy. Injection nozzles consisting of a soft tube in the number of three, for example, are disposed on the top edge and each side edge in such a manner that they are mounted to be rocked around a rocking shaft by a motor or an air rocking mechanism. Each of the injection nozzles are connected with an electromagnetic valve, an air pump, or the like. The three injection valves are rocked fanwise in an order to inject air onto the face of the shooting window through the injection nozzles during the forward period of this rocking. The nozzles on each side is rocked from top to bottom. This causes the water drops attached on the front face of the shooting window to be automatically removed, so that there is no need to wipe off water drops with cloth or the like. In addition, the injection nozzles may be automatically operated at rainfall by using a rainfall sensor.
摘要翻译：用于相机镜头组件的水滴去除装置被布置成自动地擦去附接在透镜组件的正面上的水滴等，以使得在多雨或多雪的天气中的场地拍摄变得容易。例如由3个软管构成的注射喷嘴以这样的方式设置在上边缘和每个侧边缘上，使得它们通过马达或空气摇摆机构安装在摆动轴周围。每个喷嘴与电磁阀，气泵等连接。三个喷射阀以风扇方式摇摆，以便在该摇摆的前进期间通过喷射喷嘴将空气喷射到拍摄窗口的表面上。每侧的喷嘴从上到下摇摆。这使得附着在拍摄窗口的前表面上的水滴被自动去除，因此不需要用布等擦拭水滴。此外，注射喷嘴可以通过使用降雨传感器在降雨时自动运行。
