Abstract:
1. An imaging device comprising; a light transmissive member having light transmissive character, provided between an optical system and an image pick-up portion that obtains an image from the optical system, the light transmissive member having a pair of first sides and a pair of second sides which are perpendicular to the first sides, a vibration member that causes bending vibration having a vibration node of said light transmissive member, the vibration member being provided on the light transmissive member, and a driving portion connected electrically to said vibration member so as to drive said vibration member and cause bending vibration having the vibration node of said light transmissive member along a first direction which is parallel to the first sides of the light transmissive member to cause bending vibration at a first frequency and cause bending vibration having the vibration node of said light transmissive member at along a second direction which is parallel to the second sides of the light transmissive member, and which crosses said first direction, to cause bending vibration at a second frequency which is different from said first frequency, wherein said driving portion causes bending vibration of said light transmissive member along said second direction at a different timing of the bending vibration of said light transmissive member along said first direction.
