Abstract: A lens driving device includes a base member, a movable member that is disposed at the base member and moves in a plane that is orthogonal to an optical axis, a first driving portion that moves the movable member in a direction that is orthogonal to the optical axis in accordance with image shake, a lens frame that is mounted to the movable member and moves in a direction of the optical axis, a second driving portion that moves the lens frame in the direction of the optical axis and includes a first magnet that is secured to the movable member and a first coil that is secured to the lens frame, and a Hall element that is disposed so as to oppose the first magnet in the direction of the optical axis and detects a change in a magnetic field of the first magnet.

Abstract: An optical image stabilizer includes a base member, a movable member that is disposed at the base member and moves along a plane orthogonal to an optical axis, a movable-member driving portion that is disposed at the base member and the movable member, and moves the movable member in a direction orthogonal to the optical axis, and a regulator that regulates a movement of the movable member along the plane orthogonal to the optical axis. The regulator regulates the movement of the movable member with two movement paths, which are a linear movement path along which the movable member moves in a direction orthogonal to the optical axis and a rotation path along which the movable member rotates around a point on the linear movement path.

Abstract: In a focal plane shutter according to the present invention, a support plate is placed while a plate plane of the support plate is parallel to a shutter base plate, a second blade-driving member is fitted to a shaft erectly provided on the shutter base plate, the second blade-driving member being rotated by the biasing force of a second blade-driving spring, an electromagnet for second blade is fitted to the support plate, the electromagnet attracting and holding an iron piece member fitted to the second blade-driving member, a printed wiring board on which a wiring pattern for supplying electric current to the electromagnet is formed is placed in a hole formed in the support plate, and terminal pins of the electromagnet are soldered to the both ends of a coil.
