Camera having lens barrier |
摘要 |
A camera includes a lens support frame which supports a photographing lens group; an outer lens barrel which is provided on the front end thereof with a photographing aperture through which the lens support frame is moved; a lens barrier mechanism which opens and closes the photographing aperture of the outer lens barrel; a lens drive mechanism which moves the lens support frame in the outer lens barrel between a forward movement extremity in which the front end of the lens support frame is located in front of the photographing opening in an optical axis direction, and a rearward movement extremity in which the front end of the lens support frame is located behind the photographing aperture; and a barrier detection device for detecting the opening state of the lens barrier mechanism, based on an amount of movement of the lens support frame in the optical axis direction via the lens drive mechanism.
