Title:
IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2016085245
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an imaging device capable of having a dust removing function and a shutter function while saving space and using a decreased number of components, and also initially positioning a shutter without having a special position detection nor mechanical lock mechanism.SOLUTION: An imaging device comprises: an excitation member; an optical member arranged on a subject side of an imaging element 33, and receiving vibration of the excitation member; a vibrator receiving vibration of the excitation member; a control unit controlling the excitation member; and a moving member 440 abutting on the vibrator to receive motion of the vibrator. While the excitation member has one surface stuck on the optical member and the opposite surface stuck on the vibrator, a vibration member composed of the excitation member, optical member, and vibrator has a neutral plane of vibration bending arranged outside the excitation member, and the control unit controls a vibration mode of the excitation member so as to switch between a first mode in which the moving member 440 is moved and a second mode in which foreign matter sticking on the optical member is removed by vibrating the optical member.SELECTED DRAWING: Figure 4
