Abstract
A camera includes a rigid cover formed by an integrated front cover and side cover, with the rigid cover being slidable in a transverse direction (a side direction). A lens aperture is formed in the rigid cover. A lens barrier that openings and closes the lens aperture due to the lens barrier being moved interlockingly with a sliding movement of the rigid cover is formed at a front side of a camera body. When the rigid cover is reciprocated in a state in which the lens aperture is closed, the lens aperture is opened by the lens barrier moving. When the rigid cover is reciprocated in a state in which the lens aperture is opened, the lens aperture is closed by the lens barrier moving.
Claims17
A camera comprising:
- a front cover that is disposed at a lens-mounted side of the camera, so as to be slidable with respect to a camera body mounted with the lens, and includes a lens aperture which exposes the lens;
- a movable lens barrier that can be moved between a cover position in which lens barrier covers the lens aperture and an uncover position in which the lens barrier exposes the lens aperture;
- and
- an opening/closing mechanism which moves the lens barrier interlockingly with a sliding movement of the front cover so that a reciprocal movement of the front cover away from a first position and back to the first position initiated while the lens barrier is in the cover position will perform opening of the lens aperture by moving the lens barrier to the uncover position and leaving the lens barrier in the uncover position, and wherein the reciprocal movement of the front cover initiated while the lens barrier is in the uncover position will perform closure of the lens aperture by moving the lens barrier to the cover position and leaving the lens barrier in the cover position.
A method for opening and closing a lens mounted in a camera, the method comprising:
- disposing a front cover, in which a lens aperture which exposes the lens is formed, at the lens-mounted side of the camera so as to be slidable with respect to a camera body;
- and
- opening the lens aperture with a lens barrier by moving the lens barrier interlockingly with a reciprocal sliding movement of the front cover by sliding the front cover away from a first position and then back to the first position;
- and
- closing the lens aperture with the lens barrier by again moving the lens barrier interlockingly with the reciprocal sliding movement of the front cover by sliding the front cover away from the first position and then back to the first position.
A camera comprising:
- a front cover that is disposed at a lens-mounted side of the camera, so as to be slidable with respect to a camera body mounted with the lens, and includes a lens aperture which exposes the lens;
- a movable member that can be moved between a cover position in which the member covers the lens aperture and an uncover position in which the member exposes the lens aperture;
- and
- an opening/closing mechanism which moves the member interlockingly with a sliding movement of the front cover so that a reciprocal movement of the front cover away from a first position and back to the first position initiated while the member is in the cover position will perform opening of the lens aperture by moving the member to the uncover position and leaving the member in the uncover position, and wherein the reciprocal movement of the front cover initiated while the member is in the uncover position will perform closure of the lens aperture by moving the member to the cover position and leaving the member in the cover position.
