摘要： An electro-optical scanning device with a stationary frame (13) and a movable body (15), which is movable relative to the stationary frame and carries an optical lens (17) having an optical axis (17a). An actuator means is provided for driving the movable body and a suspension means is provided for connecting the movable body to thestationary frame. The suspension means has a first compliant supporting structure and a second compliant supporting structure extending parallel to said first supporting structure. Each structure comprises a first fixing portion (19a1, 21a1, 21b1, 21b2) fixed to the stationary frame and a second fixing portion (19a2, 21a2, 21b1, 21b2) fixed to the movable body. The first supporting structure extends in a first plane being perpendicular to the optical axis of the optical lens and the second supporting structure extends in a second plane being parallel to the first plane. The second fixing portion (19a2, 21a2) of the first supporting structure is fixed in a first area (15a) of the movable body. In order to make the device suitable for use in decks of small height, the second fixing portion (19b2, 21b2) of the second supporting structure is fixed in a second area (15b) of the movable body, such that the optical axis of the optical lens passes through an intermediate area (15c) extending between the first and the second area.

摘要： An optical reproducing apparatus in which reproduction of information is carried out by using an optical record carrier. In order to compensate a radial tilt between the surface of the record carrier and the objective lens, the objective lens is tilted. In the optical apparatus of the invention, the actuator of the radial displacement of the objective lens is used to also tilt the objective lens at the same time. A displacement of the objective lens in the radial direction by the actuator has a direct effect of tilting the objective lens. This is accomplished by a mechanical link between the radial displacement and the radial tilting. This has the advantage that there is no need for an extra tilt actuator to tilt the objective lens.

摘要： A driving apparatus has at least two driving members and at least one driven member. Each of the driving members is frictionally engaged to the at least one driven member to move the driven member. The friction between each driven member and each driving member is such that the driven member moves when, over half of the driving members being in frictional engagement with the driven member, are moved, simultaneously between first and second positions. Further, the friction between each driven member and each driving member is such that the driven member substantially remains stationary when, less than half of the driving members being in frictional engagement with the driven member, are moved.
