Imaging device unit and imaging apparatus for removing dust from an optical device

摘要

An imaging device unit completely removing dust attached to an optical device and an imaging apparatus. The imaging device includes: an imaging device including an imaging surface on which an optical image of a subject is formed and converting the optical image into an electric signal; a low pass filter (LPF) disposed between the imaging device and the subject; a plate mounted on a peripheral portion of the LPF and including arm units extending in a direction parallel to the plate; a piezoelectric device mounted on the plate and vibrating the plate and the LPF; and a support frame that surface-contacts with the arm units of the plate and supports the plate in the direction parallel to the one surface of the plate.
