Claims14
An image shake correction apparatus, comprising:
- a fixed member fixed in three directions including a direction of an optical axis, a first direction perpendicular to the direction of the optical axis, and a second direction perpendicular to both of the direction of the optical axis and the first direction;
- a pair of guide shafts supported on said fixed member so as to extend in the first direction and disposed in a spaced relationship from each other in the second direction;
- an intermediate member supported on said pair of guide shafts for movement in one of the first and second directions but against movement in the other of the first and second directions with respect to said fixed member;
- a movable member having a lens or an image pickup device held thereon and supported on said pair of guide shafts for movement in the first and second directions with respect to said fixed member and for movement in the other of the first and second directions but against movement in the one of the first and second directions with respect to said intermediate member;
- a movement restraining section configured to restrain the movement of said movable member in the one of the first and second directions with respect to said intermediate member or restrain the movement of said intermediate member in the other of the first and second directions with respect to said fixed member;
- and
- a restrained section provided on said movable member or said intermediate member for being engaged at least at two locations thereof by said movement restraining section in the second direction,
- said intermediate member and said movable member being moved integrally with each other in the one of the first and second directions with respect to said fixed member while said movable member is moved in the other of the first and second directions with respect to said fixed member to carry out correction of image shake.

An image pickup apparatus, comprising
- an image shake correction apparatus for moving an lens or an image pickup device in a direction perpendicular to a direction of an optical axis to correct image shake,
- said image shake correction apparatus including
- a fixed member fixed in three directions including the direction of the optical axis, a first direction perpendicular to the direction of the optical axis, and a second direction perpendicular to both of the direction of the optical axis and the first direction,
- a pair of guide shafts supported on said fixed member so as to extend in the first direction and disposed in a spaced relationship from each other in the second direction,
- an intermediate member supported on said pair of guide shafts for movement in one of the first and second directions but against movement in the other of the first and second directions with respect to said fixed member,
- a movable member having a lens or an image pickup device held thereon and supported on said pair of guide shafts for movement in the first and second directions with respect to said fixed member and for movement in the other of the first and second directions but against movement in the one of the first and second directions with respect to said intermediate member,
- a movement restraining section configured to restrain the movement of said movable member in the one of the first and second directions with respect to said intermediate member or restrain the movement of said intermediate member in the other of the first and second directions with respect to said fixed member, and
- a restrained section provided on said movable member or said intermediate member for being engaged at least at two locations thereof by said movement restraining section in the second direction,
- said intermediate member and said movable member being moved integrally with each other in the one of the first and second directions with respect to said fixed member while said movable member is moved in the other of the first and second directions with respect to said fixed member to carry out correction of image shake.
