Image pickup apparatus capable of preventing foreign matters from adhering to optical member

摘要

An image pickup apparatus capable of preventing foreign matters from adhering to an optical member and excellent in assembly workability. Alight shield mask has a base member affixed to an object side of an optical low pass filter, which is disposed on an object side of an imaging device. An electrically conductive sheet affixed to the base member of the light shield mask is urged by an electrically conductive urging member toward the optical low pass filter. Through the electrically conductive sheet and the electrically conductive urging member mounted to a main unit chassis, the optical low pass filter is electrically connected to the main unit chassis that provides reference potential.

主权项

1. An image pickup apparatus having an imaging device that converts an optical image of an object into an electrical signal, the image pickup apparatus comprising:
an optical member disposed on an object side of the imaging device; a light shield member having an opening formed into a shape corresponding to a shape of an effective pixel area of the imaging device, the light shield member being disposed on an object-side face of the optical member; an electrically conductive urging member disposed on an object side of the optical member and configured to urge the light shield member toward the optical member; an electrically conductive member configured to be in contact with the object face of the optical member; and a reference potential member configured to provide electrical reference potential and configured to be electrically connected to the electrically conductive urging member, wherein part of the electrically conductive member is disposed on the light shield member and another part of the electrically conductive member is in contact with the object-side face of the optical member, and wherein the electrically conductive urging member urges the electrically conductive member to the object-side face of the optical member so that the electrically conductive urging member is in contact with the electrically conductive member and electrically conductive member is in contact with the object-side face of optical member.
