ABSTRACT:
A pivoting mirror device for an apparatus for optically reading information tracks on an information carrier comprises a pivoting mirror (1) which is pivotable about one or more pivoting axes (5, 6) with the aid of a mirror bearing arrangement (9), which arrangement comprises a rigid bearing support (10) and an elastic bearing (13) made of a rubber-like material, which is connected both to the pivoting mirror and to the bearing support and which partly surrounds the bearing support. In order to obtain a suitable ratio between the rigidity of the pivoting mirror bearing in desired pivoting directions and the rigidity in undesired articulating directions, the portion (14) of the bearing support located in the elastic material has a cross-section which varies from a minimum transverse dimension at the end (11) of the bearing support near the pivoting mirror to a maximum transverse dimension at a location which is more remote from the pivoting mirror (15). (FIG. 1).
