Abstract
A vibration reducing apparatus includes a vibration reducing optical system for reducing vibrations, a frame for holding the vibration reducing optical system, a first driving force generation device for driving the frame in a first direction on a plane substantially perpendicular to the optical axis of a main optical system, a second driving force generation device for driving the frame in a second direction perpendicular to the first direction on the plane, and a guide portion for guiding the frame in a guide direction that is skewed relative to the first and second directions at predetermined angles, and moving the frame in a direction perpendicular to the guide direction.
Claims9
A vibration reducing apparatus comprising:
- a vibration reducing optical system for reducing vibrations;
- a frame for holding said vibration reducing optical system;
- a first driving force generation device for driving said frame in a first direction on a plane substantially perpendicular to an optical axis of a main optical system;
- a second driving force generation device for driving said frame in a second direction perpendicular to the first direction on the plane;
- and
- a guide portion for guiding said frame in a guide direction that is skewed relative to the first and second directions at predetermined angles, and moving said frame in a direction perpendicular to the guide direction.
A vibration reducing apparatus comprising:
- a vibration reducing optical system for reducing vibrations;
- a frame for holding said vibration reducing optical system;
- a driving force generation device for driving said frame in a predetermined direction which is substantially perpendicular to an optical axis of a main optical system;
- and
- a guide portion for guiding said frame in a guide direction which is skewed relative to the predetermined direction at a predetermined angle, and moving said frame in a direction perpendicular to the guide direction.
A vibration reducing apparatus comprising:
- a vibration reducing optical system for reducing vibrations upon being driven in directions substantially perpendicular to an optical axis of a main optical system;
- a frame for holding said vibration reducing optical system;
- a driving force generation device for driving said frame;
- a guide portion for guiding said frame in a predetermined direction, said guide portion including a first guide member having a guide surface, and a second guide member having a contact portion which is in contact with the guide surface;
- a biasing portion for biasing the guide surface and the contact portion in a direction to bring them into contact with each other, and permitting the guide surface and the contact portion to move in a direction to separate from each other;
- and
- a shock absorbing portion for absorbing a shock exceeding an allowable shock produced between the guide surface and the contact portion.
