IMAGE PICKUP ELEMENT UNIT, AUTOFOCUS UNIT, AND IMAGE PICKUP APPARATUS

摘要

An image pickup element unit is used for an image pickup apparatus having an autofocus function configured to determine a direction in which an in-focus position is located by wobbling in an optical axis direction an image pickup element configured to photoelectrically convert an optical image formed by an image pickup optical system. The image pickup element unit includes a deformable member connected with the image pickup element and configured to deform when receiving a force, a support configured to support the deformable member and to serve as a fulcrum when the deformable member deforms so that the deformable member can move the image pickup element in the optical axis direction, and a weight fixed onto the deformable member and configured to move reverse to the image pickup element as the image pickup element moves.
