Patent ID: 7609315

Claim:
A dust removal camera comprising: an image pickup optical system which forms an optical image of an object; a photoelectric converting device which converts the optical image to an electric signal; a mechanical shutter disposed between the image pickup optical system and the photoelectric converting device; a low pass filter disposed between the mechanical shutter and the photoelectric converting device; a rectangular optical device provided between the mechanical shutter and the low pass filter; a vibration absorbing body disposed between the rectangular optical device and the low pass filter, and formed surrounding an image formation light ray passing-through area of the rectangular optical device; pair of piezoelectric bodies disposed on a surface of the rectangular optical device with the vibration absorbing body therebetween, the pair of piezoelectric bodies vibrating so as to generate bending vibration on the image formation light ray passing-through area of the rectangular optical device; electric terminals connected to the pair of piezoelectric bodies, a part of the electric terminals drawn out from a contact surface of the rectangular optical device and the piezoelectric bodies; and an oscillator which applies cyclic voltage via the electric terminals to the pair of piezoelectric bodies for vibrating each piezoelectric body thereof.
