Patent ID: 8218060

Claim:
An imaging apparatus comprising: an image forming element having an image surface on which an optical image is generated; an optical element including a light-transmitting portion through which a subject light passes, the light-transmitting portion being disposed so as to face an image surface of the image forming element with a predetermined distance; a vibration member for vibration application arranged at a position which is other than a position where the light-transmitting portion of the optical element is arranged, the vibration member for vibration application vibrating not only a surface of the optical element but also inside of the optical element; and a vibration member for vibration absorption arranged at a position which is other than the position where the light-transmitting portion of the optical element is arranged and which is opposed to the vibration member for vibration application, the vibration member for vibration absorption absorbing a part of vibration of the optical element in a predetermined cycle, wherein when a wavelength of vibration generated in the optical element by vibration of the vibration member for vibration application is defined as λ, and an odd number as k, the vibration member for vibration application and the vibration member for vibration absorption are arranged separately from each other at positions on the surface of the optical element such that a distance between centers of the members is expressed by k×λ/4.
