摘要： An optical pickup device comprising an objective lens having an optic axis for focusing a light beam emitted from a light source on an optical recording medium. The objective lens is carried on a support member which is coupled with a base through a coupling unit. The coupling unit has a first rotation axis parallel to the optic axis for permitting rotation of the support member about the first rotation axis in a tracking direction perpendicular to the optic axis and a second rotation axis perpendicular to the optic axis for permitting rotation of the support member about the second rotation axis in a focusing direction parallel to the optic axis. The support member has a center of gravity positioned substantially on the first rotation axis. A light beam reflected from the optical recording medium is sensed for exerting a force on the support member to move the objective lens in the focusing and/or tracking directions so as to adjust the optic axis to a desired position.

摘要： An optical scanning device is provided, which is compact-sized and lightweight, and, which consumes less power. A movable member of the device is supported on a fixed member via a swing axis provided on the fixed member. On an upper surface and along an axial line of swing of the movable member, there are disposed a light emitting unit and a light receiving unit. When an AC current flows through a coil provided in the movable member, electromagnetic force acting on the coil when traversing a magnetic circuit comprising a yoke and a permanent magnet both provided on the fixed member urges the movable portion to swing around its swing axis at a predetermined cycle. A laser bean L from the light emitting unit scans a bar code and a reflected light L′ from the bar cord is received by the light receiving unit thereby reading information of the bar code. The above structure of the device minimizes the drop in the efficiency of light reception and contributes to a compact and lightweight design, and less power consumption.
