Title: Objective lens holder

Abstract: An objective lens holder applicable in a pickup head of an optical media device is disclosed. The lens holder overcomes the problems of unstable movement and complicated assembly of the conventional lens holders. The invented lens holder uses four stripe-like resilient supporting arms, which are made from a unitary sheetmetal by a press-cutting and a bending process, to support the lens carrier and the lens. One ends of the supporting arms are settled with a fixing member when the fixing member is resin-molded, and the other ends are linked with the lens carrier. Each supporting arm includes two strips which ensure the supporting arm moving stably in the tracking direction and the focusing direction respectively. The assembly is simplified by the unitary sheetmeetal workings and the resin-molding process.
