Patent ID: 7742691

Claim:
An image stabilizer comprising: a driver including a first coil that is supported by a first coil supporting portion of a flexible printed circuit board, a second coil that is supported by a second coil supporting portion of the flexible printed circuit board, a first magnet and a second magnet, the first coil and the first magnet being configured to move relative to each other, the second coil and the second magnet being configured to move relative to each other, said first coil supporting portion of the flexible printed circuit board being directly mounted on a first magnetic plate that is attracted by a magnetic force of the first magnet, said second coil supporting portion of the flexible printed circuit board being directly mounted on a second magnetic plate that is attracted by a magnetic force of the second magnet, said driver being configured to control an optical component; a first movable frame that holds said optical component and that is configured to move in a first direction perpendicular to an optical axis of a lens system; a second movable frame that is configured to move in a second direction perpendicular to the first direction and said optical axis, the first movable frame being supported by the second movable frame so as to be movable relative to the second movable frame; and a fixed support frame, the second movable frame being supported by the fixed support frame so as to be movable relative to the fixed support frame, said first and second coils and said first and second magnets being arranged such that either said first and second coils are fixed to said first movable frame and said first and second magnets are fixed to said fixed support frame or said first and second magnets are fixed to said first movable frame and said first and second coils are fixed to said fixed support frame, said first coil being configured to move said optical component in said first direction, said second coil being configured to move said optical component in said second direction, said first and second magnets being configured to respectively apply magnetic force to said first coil and said second coil, said first coil and said second coil being disposed such that a direction of thrust generated from said first coil by the magnetic force of said first magnet is said first direction and a direction of thrust generated from said second coil by the magnetic force of said second magnet is said second direction, each of said first direction and said second direction forming an angle of approximately 45° with a line connecting the optical axis of said optical component and the center of a lens barrel.
