Title:
LENS BARREL AND IMAGING APPARATUS
Document Type and Number:
Japanese Patent JP2019144336
Kind Code:
A
Abstract:
To provide a lens barrel having a structure capable of contributing to the improvement of an image blur correction function by suppressing the influence of vibrations except a camera-shake on an acceleration sensor with a simple configuration.SOLUTION: A lens barrel 10 which is attached to an imaging apparatus body 30 and includes an imaging optical system comprising a plurality of optical elements inside includes an image blur correction mechanism 18 which drives a part of the plurality of optical elements, to correct an image blur, a ring-like electronic circuit board 14 in which a pair of acceleration sensors 41 are arranged in respective positions facing each other across the optical axis O of the imaging optical system, and a lens barrel body 11 which stores at least the imaging optical system, the image blur correction mechanism, and the ring-like electronic circuit board. The ring-like electronic circuit board is fixed to the lens barrel body so as to be perpendicular to the optical axis of the imaging optical system and the respective positions where the pair of acceleration sensors are fixed are positions where each of the pair of acceleration sensors outputs the same signal, when the vibrations except the camera-shake are generated from the imaging apparatus body.SELECTED DRAWING: Figure 2
