Summary:PURPOSE:To clean an optical system without necessitating any additional work by providing a cleaner for cleaning the optical system in a moving path for this optical system movable in the radial direction of an optical disk. CONSTITUTION:The cleaner 7 is provided in the outermost circumferential position of a carriage 5 capable of moving in the radial direction of the optical disk 1 in a housing 2. When a cartridge case is not loaded into the housing 2, the carriage 5 mounted with the optical system 4 is moved to its movable outermost circumference in the radial direction of the optical disk 1, so that the leaner 7 installed there is slid in contact with the optical system 4, thus cleaning the optical system 4. The installing position of the cleaner 7 is not necessarily specified, in particular, as the outermost circumferential position but wherever in the moving path of the optical system 4.
