An optical disc recording and/or reproducing device comprising a drive for rotating an optical disc around an axis of rotation, a movable optical pickup unit (5) and a frame (1) having at least one guiding rod (4) for guiding a displacement of the optical pickup unit (5) in a substantially radial direction with respect to the axis of rotation. The guiding rod (4) is provided with a protrusion (17) for restricting the movement of the optical pickup unit (5) when the guiding rod (4) is in a predetermined rotational position. The guiding rod (4) is rotationally drivable by an electric drive motor in order to move the protrusion (17) for either releasing or blocking the optical pickup unit (5).
