JP2014059343A5 - Lens barrel and imaging device having the same - Google Patents

Description

The present invention relates to a lens barrel and an imaging device including the lens barrel, and more particularly to a lens barrel having a barrier device.

Accordingly, an object of the present invention is to reduce the size of the lens barrel and to sufficiently secure the adhesive strength between the barrier cover and the barrier holding frame (barrier holding member), and to provide an image with the lens barrel. To provide an apparatus.

To achieve the above object, the present onset Ming is disposed in the optical axis direction the object side of the imaging lens, a barrier cover inlet elevation aperture through which light enters is formed on the imaging lens, the entering-morphism opening is superimposed in the opened state of opening, a lens barrel and a first barrier member and a second barrier member for protecting the image pickup lens is deployed in the closed state to block the entering-morphism opening, said first a barrier driving member for driving movement of the first barrier member and the second barrier member, which holds the barrier driving member, bonding surface for bonding holds the barrier cover to the optical axis direction the object side is formed has a barrier holding member, and wherein the barrier holding member are entering hole is formed in the rear side of the adhesive surface, the the first barrier member moving range of the second barrier member And restricting portion is formed to win, wherein the penetration portion is a part of the regulating portion enters the penetration hole with the opening operation of the first barrier member.

Hereinafter, an example of a lens barrel including a barrier device according to an embodiment of the present invention will be described with reference to the drawings.

On the other hand, when the user intentionally moves the first to third barrier blades 3 to 5 in the opening direction from the closed state of the first to third barrier blades 3 to 5 or when an impact is applied, barrier driving ring 2 while holding the closed position, the first barrier blade 3 is moved to the open position. At this time, if the intruding portion 3j of the first barrier blade 3 and the sliding surface 2h of the barrier drive ring 2 collide, the first barrier blade 3 or the barrier drive ring 2 may be deformed.
