However, the cleaner case 10 is located at
A rotating shaft 14 is rotatably attached to the cleaner case 10 via a bearing 13 so that the mounting direction is parallel to the moving direction of the objective lens 2 when attached to the drive device. A rotating brush 14 is attached to the center, and the width of this rotating brush 14 is wider than the lens movement range. 15 is a rotating blade attached to the end of the rotating shaft 12; 16
