Abstract

Camera and camera element unit are provided in the invention. The camera includes an image pick-up device which obtains an image signal corresponding to beams irradiated onto a photoelectrically converting surface thereof; a dust-proofing member with a circular or polygonal plate-shape as a whole, including a transparent portion at an area having at least a predetermined extensity in a radial direction from the center thereof, opposed to the front of the optical device at a predetermined interval; a member for vibration annularly arranged at a peripheral portion of the dust-proofing member, which applies vibrations to the dust-proofing member; a sealing structure arranged to constitute a space portion that is substantially sealed at a portion formed by opposing the image pick-up device and the dust-proofing member by sealing the space portion at peripheral portions of the image pick-up device and the dust-proofing member; and an image signal processing circuit which converts an image signal obtained from the image pick-up device, corresponding to an image formed onto the photoelectrically converting surface of the image pick-up device, into a signal suitable to recording.

Description

technical field [0001] The present invention relates to an imaging element unit having an imaging element that obtains an image signal corresponding to light irradiated on its photoelectric conversion surface, and a camera having the imaging element unit, and more specifically, to a single-lens reflex type digital camera with an interchangeable imaging lens. A camera, etc., a camera having a dust-proof structure of an imaging element, and an imaging element unit used in the camera. Background technique [0002] In recent years, digital cameras such as so-called digital still cameras and digital video cameras (hereinafter simply referred to as digital cameras or still cameras) have been put into practical use and widely popularized. (also called a photographic lens) The object image formed by the light beam of the object (hereinafter referred to as the object light beam) is placed on a solid-state imaging device at a predetermined position, such as a charge-coupled device (CC...
