Title:
LENS BARREL AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/047592
Kind Code:
A1
Abstract:
Provided are a lens barrel and imaging device which make it possible to improve the ability to hold in first and second rotation positions, and to obtain clearly distinct clicking feelings that are produced when aligning the diaphragm operation ring with the first rotation position, which corresponds to a principal series, and when aligning the same with the second rotation position, which corresponds to an auxiliary series. A lens barrel (12) is equipped with an imaging optical system (22), a diaphragm operation ring (24), and click stop mechanisms (27, 28). The click stop mechanism (27) is configured from a first spherical body (60), a first engaging part (61), and a first biasing member (62). The click stop mechanism (28) is configured from a second spherical body (65), a second engaging part (66), and a second biasing member (67). The first spherical body (60) engages the first engaging part (61) when the diaphragm operation ring (24) is set to a position that corresponds to the principal series. The second spherical body (65) engages the second engaging part (66) when the diaphragm operation ring (24) is set to a position that corresponds to the auxiliary series.
