The camera includes an image pick-up device which obtains an image signal corresponding to beams irradiated onto a photoelectrically converting surface thereof, an optical device arranged on the side of the photoelectrically converting surface of the image pick-up device, 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 optical device in front thereof at a predetermined interval, a member for vibration arranged at a peripheral portion of the dust-proofing member, which applies vibrations to the dust-proofing member, a sealing structure arranged outside a peripheral portion of the optical device or an adjacent portion thereof, the sealing structure forming a space portion, that is substantially sealed, including an air gap portion formed by opposing the optical device and the dust-proofing member, and sealing the space portion at a peripheral side of the optical 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.
