A lens driving device having a movable frame on which a magnet is secured, supporting the lens; a base member supporting the movable frame movably; and a cover member, equipped with an opening enabling light to be incident into the lens, covering the movable frame and a supporting face of the base member, wherein: either a coil or a position sensor that faces a magnet is provided on the supporting face of the base member. The other, either the position sensor or the coil that faces the magnet, is provided on a supporting face of the cover member, and an interconnection member that is connected to the coil or the position sensor that is provided on the cover member is formed integrally with the cover member.

Lens driving device

The housing includes a plate-shaped base; and a cover provided with a bottom plate and a side plate, and covers a main surface of the base. The base has in the main surface, a wall part which extends along the peripheral edge of the main surface, and faces the side plate of the cover. The side plate having an opening exposing a portion of the wall part. An adhesive bonding the base and the cover together is provided in a gap between the wall part and the side plate. The cross-sectional area of the gap in a cross section orthogonal to at least one direction from the direction from the wall part exposed from the opening, to either end of the wall part in the length direction, and the direction from the height-direction end of the wall part exposed from the opening, to the main surface of the base, decreases in said at least one direction.

Housing, lens drive device provided with same, imaging device, electronic apparatus, and housing production method

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.

A digital camera includes at least one shutter blade in which opening and closing operations of an exposure aperture are performed using an electromagnetic actuator. The digital camera also includes an image sensor converting light from an object into image information, and an image processing circuit which stores the image information converted by the image sensor in an image memory so that the image information can be fetched and such that the image processing circuit has terminals for connecting the image processing circuit to an estimation display device. Further, the digital camera includes an exposure control circuit including a reference table controlling the amount of light exposure and at least one correction table allowing the amount of light exposure controlled by the reference table to be corrected, and includes a driving circuit driving the electromagnetic actuator according to an output signal of the exposure control circuit.
