Abstract

PURPOSE:To easily and securely remove dust deposited on an objective by providing a cleaning member for an optical pickup and a transmission means which transmits the rotary motion of a driving means to the cleaning member in a storage cassette. CONSTITUTION:The outer appearance of a cartridge 1 is in a flat plate shape similarly to a storage member where an optical medium is stored, and a hub 2, gears 3-6, and a cotton ball 7 for cleaning the objective 24 of the optical pickup 23 are stored in the internal space while held by shafts 8-10. The hub 2 is coupled with a turntable 21 on the driving motor 22 of an optical disk device and the rotary motion is transmitted to the cotton ball 7 impregnated with a solvent for cleaning previously while decreasing the rotation speed gradually by the gears 3-6. Consequently, the dust deposited on the objective 124 is easily and securely removed.
