Abstract
In a conventional lens cleaner for a disk unit, dust is removed by bringing planted brushing hair bundles or projections into contact with a lens, and thus a large quantity of planted brushing hair bundles or projections may impede insertion and removal of the disc from the disc unit, or may cause flaws on the lens. A lens cleaner for a disc unit in the present device comprises a cleaning disc in the identical configuration with the disc and at least a through hole, wherein dust is removed by applying the air flow generated through the through hole during the rotation of the disc onto the lens.
