Patent ID: 7324149

Claim:
A camera comprising: an image pick-up device which obtains an image signal corresponding to beams irradiated onto a photoelectrically converting surface thereof; a dust-proofing member having a substantially circular or polygonal plate-shape, and comprising a transparent portion at an area having at least a predetermined length in a radial direction from a center thereof, the transparent portion being opposed to a front of the image pick-up device at a predetermined interval; a member for vibration which is arranged at a peripheral portion of the dust-proofing member, and 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; wherein the dust proofing member is supported to the sealing structure near a node of vibrations caused by the member for vibration; wherein the member for vibration comprises piezoelectric ceramics.
