Abstract

An optical scanning device with two holding devices for a compact disk player is fastened by means of one holding device in such a manner that the scanning device or its objective lens can move parallel to the optical axis and parallel to the surface of the disk. To ensure parallel guiding of maximum precision, the holding device is composed of two end parts (E), two intermediate parts (Z) and at least one central part (M). The axes of rotation of the joints (K1), each of which connects an end part (E) to an intermediate part (Z), are perpendicular to the axis of rotation of the joint (K2) which connects the central part (M) on both sides to an intermediate part (Z). The holding device can be made from a piece of plastic with notches at the joint points which form bending points that function as joints. Application to mechanical and optical scanning devices, for example, for compact disk players.
