Abstract

PURPOSE: To make the drive part of an objective lens compact by supporting a bobbin mounted with an objective lens by the two 1st plate springs nearly in parallel and the plate spring connected to the 1st plate springs movably in horizontally and in the left/right directions.
CONSTITUTION: The objective lens 21 is mounted on the bobbin 20 of nearly rectangle, the 1st coil 30 (focus coil) driving vertically the bobbin 20 at the outer surrounding and a couple of the 2nd coils 31A, 31B (32A, 32B) (tracking coils) shaking horizontally the bobbin 20 are provided, then the objective lens 21 is driven vertically and horizontally. In this case, the bobbin 20 is supported movably vertically by two plate springs 22, 23 in parallel and then supported shakingly horizontally by the 2nd plate spring 27, then the drive part and support part of the bobbin 20 are separated completely. Thus, the bobbin 20 is formed with light weight and small size.
