Abstract
A cleaning apparatus for an object lens which can provide a sufficient cleaning effect without affecting the supporting mechanism of an objective lens. The cleaning apparatus is inserted into a disk loading portion and cleans the object lens incorporated in an optical disk apparatus. The cleaning apparatus has a housing having approximately the same shape as the cartridge type optical disk. A brush protrudes from the housing and slide on the object lens when the cleaning apparatus in inserted into the optical disk apparatus. A sliding direction of the brush is set to be a predetermined direction between the inserting direction of the cleaning apparatus and a direction perpendicular to the inserting direction. Only components of force due to the sliding of the brush against the object lens, which components of force are smaller than the sliding force, are exerted to the object lens in a movable direction of the object lens for tracking adjustment and a direction perpendicular to the movable direction.
