ABSTRACT:
An optical system support construction such as in a compact disc player includes a first pair of leaf springs having one ends fixed, a second pair of leaf springs having one ends fixed to free ends of the first pair of leaf springs, and an optical system component such as an objective lens supported on free ends of the second pair of leaf springs. The ratio of the spring constant of the first pair of leaf springs to the spring constant of the second pair of leaf springs is inversely proportional to the square root of the length of the first pair of leaf springs to the length of the second pair of leaf springs.
