ABSTRACT:
A disk apparatus includes a metallic chassis unit including a portion being grounded. A movable unit is provided to be movable relative to the chassis unit between an inserted position and a pulled-out position, the movable unit including an optical disk and electric parts for reproducing a signal indicative of information from the optical disk, the movable unit being included in the chassis unit when the movable unit is moved to the inserted position, and being pulled out from the chassis unit when the movable unit is moved to the pulled-out position. A conductive member is provided in the movable unit to protect the electric parts against a discharging of static electricity, the conductive member being electrically connected to the chassis unit when the movable unit is at the inserted position, the electric connection allowing a flow of a discharging current between an operator and the grounded portion of the chassis unit, and the conductive member being separated from the chassis unit when the movable unit is at the pulled-out position.
