Optical disc player signal reading device with improved drive structure for moving optical pickup in orthogonal directions

摘要

An optical player signal reading device in which a supporting member having inner and outer cylinders pivotally supports an optical pickup. One of the inner and outer cylinders is made of an elastic material or, alternatively, an elastic piece is disposed between the inner and outer cylinder. The pickup is pivoted by a pair of tracking-direction drive sections disposed above and below the supporting member with the elastic component of the supporting member acting as a fulcrum. A focus-direction drive section moves the pickup in the focusing direction.
