  • Scanning lens mount using deflection and twisting for separate movements
    Patent number: 5367511
    Abstract: The objective lens of a scanning device is mounted in a movable section which is interconnected to a mounting section by two supports which extend parallel to each other and the lens axis and transverse to a direction of movement for correcting tracking errors. Each support has two first members, one movable and one fixed, having central portions fixed to the movable and mounting sections respectively, and two stiff second members connecting respective ends of the first members. Between the central portions and the ends, the first members are elastically deflectable to correct focussing errors, and elastically twistable to correct tracking errors.
