A playback apparatus, in particular a video player, for playing back round disks, which are provided with information tracks which are optically readable with the aid of a read beam obtained from a light source, and having a housing which comprises a substantially flat covering plate and an optical focussing device movable to and fro in a slot in the covering plate. In view of the safety of the apparatus and for other, such as aesthetical, reasons the slot is closed by a closing element in every position of the focussing device, which element is connected to the focussing device and for example consists of a flexible strip of a width greater than the width of the slot.
