ABSTRACT:
This apparatus deflects away from the lens of a camera dirt and the like, which may be thrown at it. The camera is enclosed within a housing with the lens protruding from the front wall of the housing. A protector plate is fixedly connected to the housing front wall by a plurality of spacers and has an opening in registry with the camera lens. A fan is rotatably mounted intermediate the circular plate and the housing front wall, with its axis of rotation eccentric with respect to the camera lens and the plate opening. The fan includes a plurality of spaced-apart blades movable across the camera lens and spacedly in front of it to deflect away from the lens any dirt particles which might enter the plate opening. The speed of the fan is such that the fan blades will not impair the quality of the image captured by the lens.
