发明名称 Objectivlinsenhalterung und Objectivlinsenantriebsgerät
摘要 An object lens holder (1) for holding an object lens (17) for converging a laser light radiated from a laser light source on a signal recording surface of an optical recording medium includes a bobbin part (4) formed by abutting and connecting first and second bobbin halves (2, 3) which are counterparts to each other, a holder part (7) formed by abutting and connecting first and second holder halves (5, 6) which are counterparts to each other, which holder part (7) is used as a mounting supporting part to a supporting base plate (75), first and second resilient deflecting members (8, 9) arranged in parallel to each other for interconnecting the first bobbin half (2) and the first holder half (5), and third and fourth resilient deflecting members (10, 11) arranged in parallel to each other and to the first and second resilient deflecting members (8, 9) for interconnecting the second bobbin half (3) and the second holder half (6). This object lens holder (1) may be assembled continuously and in larger quantities, and is a component of an object lens driving device for accurately driving and displacing the object lens (17) in a direction along its optical axis and in a direction normal to this optical axis. <IMAGE>
