Title:
LENS BARREL AND IMAGING APPARATUS
Document Type and Number:
Japanese Patent JP2019168561
Kind Code:
A
Abstract:
To provide a lens barrel capable of selectively inserting/removing an optical element into/from a photographic optical axis or switching the optical element and including a lock mechanism whose regulation is released only when performing a switching operation.SOLUTION: In the lens barrel including a holding frame for holding one optical element, a base member for holding the holding frame so as to perform switching between a first state where one of the optical elements possessed by the holding frame is arranged on the photographic optical axis and a second state where one of the optical elements is arranged out of the photographic optical axis, and a rotary barrel for driving a zoom lens group in an optical axis direction, the rotary barrel has a first rotational phase and a second rotational phase, regulation means for preventing the first state and the second state from being switched by the holding frame and the rotary barrel, when the rotary barrel is in the first rotational phase is configured, and the holding frame is linked with the rotary barrel so as to switch the first state and the second state and a part of the first rotational phase is overlapped with a part of the second rotational phase, when the rotary barrel is in the second rotational phase.SELECTED DRAWING: Figure 12(A)
