OPTICAL ELEMENT HOLDER, OPTICAL ELEMENT UNIT, AND OPTICAL PICKUP APPARATUS |
摘要 |
A holder has walls defining a holding region for holding an optical element, and has a protrusion part overlapping the holding region. The protrusion part is formed at a deformable support part, and can be displaced in a direction away from the holding region by deformation of the support part. When the optical element is fitted into the holding region, the support part deforms and the protrusion part runs on a side surface of the optical element. In this state, the optical element is pressed until a back surface of the optical element abuts a support surface of the holder. The optical element is pressed against the wall and positioned by a return force of the support part.
