Abstract
A correction optical member can be locked and unlocked without wasting electric power or requiring cumbersome operations. A locking control member (16) for operating a locking member (20) in synchronism with movement of a lens barrel for holding an optical system including a correction optical member (17a) between a collapsed state and a photographing preparation state is arranged. The locking member is operated in synchronism with a projecting operation of the lens barrel from the collapsed state to the photographing preparation state and a retracting operation of the lens barrel from the photographing preparation state to the collapsed state, so that the correction optical member is set in a swingable state or is locked at a predetermined position.
Claims50
An optical apparatus having a vibration suppression function, comprising:
- a lens member movable at least to positions corresponding to non-photographing and photographing preparation states;
- a vibration suppression member for optically correcting a blur of image;
- and
- a locking member for selectively switching said vibration suppression member between an operative state and an inoperative state, said locking member switching said vibration suppression member to the inoperative state in response to a movement of said lens member to the position corresponding to the non-photographing state.
An optical apparatus having a vibration suppression function, comprising:
- a lens member movable at least to positions corresponding to inactive and active preparation states;
- a vibration suppression member for optically correcting a blur of image;
- and
- a locking member for selectively switching said vibration suppression member between an operative state and an inoperative state, said locking member switching said vibration suppression member to the inoperative state in response to a movement of said lens member to the position corresponding to the inactive state.
An optical apparatus having a vibration suppression function, comprising:
- a lens member movable at least to positions corresponding to non-photographing and photographing preparation states;
- a vibration suppression member for optically correcting a blur of image;
- a locking member for selectively switching said vibration suppression member between an operative state and an inoperative state;
- and
- a position detection member for detecting a position of said lens member, said locking member switching said vibration suppression member to the inoperative state in response to detection of a movement of said lens member to the position corresponding to the non-photographing state by said position detection member.
An optical apparatus having a vibration suppression function, comprising:
- a lens member which can change its state at least to inactive state and active preparation state;
- a vibration suppression member for deflecting a light beam for said lens member according to a vibration of said apparatus;
- and
- a switching member for selectively changing the operation state of said vibration suppressing member to an operative state or inoperative state, said vibration suppression member changing the operation state of said vibration suppression member in response to the changeover of the operation state of said lens member.
An optical apparatus, comprising:
- a movable lens member;
- a vibration suppression member for optically suppressing a vibration;
- a changing member for selectively changing-over said vibration suppression member to operable state and to inoperable state, said changing member performing the changing-over to the operation state of said vibration suppression member in response to a movement of said lens member.
An optical apparatus using (i) lens means being selectively movable to a using state and a non-using state, and (ii) an image blur prevention portion for image blur prevention, said apparatus comprising:
- determining means for determining movement of the lens means to the non-using state;
- and
- response means for causing the image blur prevention portion to be inoperative in response to determination by said determining means of movement of the lens means to the non-using state.
An optical apparatus using (i) lens means being selectively movable to a using state and a non-using state, and (ii) an image blur prevention portion for image blur prevention, said apparatus comprising:
- determining means for determining movement of the lens means from the non-using state to the using state;
- and
- response means for switching the image blur prevention portion from an inoperative state to an operative state in response to determination by said determining means of movement of the lens means from the non-using state to the using state.
An optical apparatus using (i) lens means being selectively movable to a using state and a non-using state, and (ii) an image blur prevention portion for image blur prevention, said apparatus comprising:
- connection means connecting to the lens means for following movement of the lens means in which the lens means moves between the using state and the non-using state;
- and
- translation means for moving the image blur prevention portion to an operative state and to an inoperative state, said translation means being operable in response to said connection means following the movement of the lens means.
A camera using (i) lens means being selectively movable to a using state and a non-using state, and (ii) an image blur prevention portion for image blur prevention, said camera comprising:
- determining means for determining movement of the lens means to the non-using state;
- response means for causing the image blur prevention portion to be inoperative in response to determination by said determining means of movement of the lens means to the non-using state.
A camera using (i) lens means being selectively movable to a using state and a non-using state, and (ii) an image blur prevention portion for image blur prevention, said camera comprising:
- determining means for determining movement of the lens means from the non-using state to the using state;
- and
- response means for switching the image blur prevention portion from an inoperative state to an operative state in response to determination by said determining means of movement of the lens means from the non-using state to the using state.
A camera using (i) lens means being selectively movable to a using state and a non-using state, and (ii) an image blur prevention portion for image blur prevention, said camera comprising:
- connection means connecting to the lens means for following movement of the lens means in which the lens means moves between the using state and the non-using state;
- and
- translation means for moving the image blur prevention portion to an operative state and to an inoperative state, said translation means being operable in response to said connection means following the movement of the lens means.
