PHN 9869 12 ABSTRACT: A pivoting-mirror device for are apparatus for optically reading information tracks on an information carrier comprises a pivoting mirror which is pivotable about one or more pivotal axes with the aid of a mirror bearing arrangement, which arrangement comprises a rigid bearing support and an elastic bearing made of an elasto- meric material, which is connected both to the pivoting mirror and to the bearing support and which partly sur- rounds the bearing support. In order to obtain a suit- able ratio between the rigidity of the pivoting mirror bearing in desired pivoting directions and the rigidity in undesired directions of movement, the portion of the bearing support located in the elastic material has a cross-section in a plane or planer perpendicular to the pivotal axis or axes which varies from a minimum trans- verse dimension at the end of the bearing support near the pivoting mirror to a maximum transverse dimension at a location which is more remote from the pivoting mir- ror.
