IMAGE CAPTURING DEVICE INCLUDING BAYONET COUPLING SECTION IN LENS BARREL AND ACCESSORY Russian patent published in 2014 - IPC G03B17/12 

FIELD: physics, photography.

SUBSTANCE: invention relates to an image capturing device and an accessory which can be mounted on the image capturing device, and more specifically to an image capturing device having a first bayonet coupling section, designed for mounting the accessory, around the a lens barrel. The image capturing device comprises a first bayonet coupling section which is formed around a lens barrel; a first member configured to have a second bayonet coupling section formed thereon, said second bayonet coupling section being capable of being engaged with said first bayonet coupling section; a rotational operation member configured to rotate with respect to said first member, by being rotationally operated by a user; a second member configured to rotate synchronously with said rotational operation member when the user rotates said rotational operation member; a detection unit configured to detect rotation of said second member; a first lock member configured to restrict rotation of said first member with respect to said first bayonet coupling section when said first bayonet coupling section and said second bayonet coupling section are engaged with each other; and a second lock member configured to restrict rotation of said rotational operation member and said second member with respect to said first member in accordance with an operation for releasing rotation restriction of said first member.

EFFECT: providing an image capturing device which enables to make a bayonet coupling section around a lens barrel, designed for mounting an accessory, and make a rotational operation member around the lens barrel without increasing the size of the image capturing device.
