A lens driving device includes a lens holding portion, a driving shaft, a vibration member, and a spring member. The vibration member is connected to one end of the driving shaft and causes the driving shaft to micro-vibrate. The spring member is fixed to the lens holding portion and includes a grip portion that sandwiches and grasps the driving shaft. Extension piece portions that protrude while being bent so as to be separated from the driving shaft are provided at end sides of the grip portion in an axial direction of the driving shaft.

Lens driving device, camera device and electronic apparatus

A lens driving device includes: a fixed portion; a movable portion including a lens carrier that holds a lens body; a middle portion provided between the fixed portion and the movable portion; a first elastic support member movably supporting a front portion of the middle portion with respect to the fixed portion in a direction orthogonal to an optical axis of the lens body; and a second elastic support member movably supporting the movable portion with respect to a rear portion of the middle portion in a direction orthogonal to the optical axis of the lens body.

A lens driving device includes a first movable lens holding portion that holds a first movable lens body, a second movable lens holding portion that holds a second movable lens body heavier than the first movable lens body, a first driving shaft that drives the first movable lens holding portion and a second driving shaft that drives the second movable lens holding portion, and a first guide shaft and a second guide shaft thicker than the first guide shaft. The first and second guide shafts are arranged in parallel with the first driving shaft and the second driving shaft. Loads of the first movable lens holding portion and the second movable lens holding portion are respectively and independently supported and guided by one of the first and second guide shafts, and rotation is prevented by the other of the first and second guide shafts.

An image blur correction apparatus includes a focus adjustment unit for moving a lens body in the direction of its optical axis; an image blur correction unit; and a housing having a housing front side wall on the front side of the direction of the optical axis and disposed outside said focus adjustment unit and the image blur correction unit, the focus adjustment unit has a focus adjustment unit front side wall on the front side of the direction of the optical axis, the focus adjustment unit front side wall including an exposed portion provided around the insertion hole and a hollow portion recessed toward the rear side of the direction of the optical axis with respect to said exposed portion; and the hollow portion and the rear side of the housing front side wall in the direction of the optical axis are provided to face opposite each other.

Image blur correction apparatus; camera device and electronic device

A piezoelectric driving device includes: a driving portion to be brought into frictional contact with an object to be driven, which is moved with respect to a fixed body; and at least two piezoelectric portions, which are formed integrally with the driving portion, are arranged on a predetermined plane with the driving portion being sandwiched between the at least two piezoelectric portions, and are configured to be bent with respect to the predetermined plane when voltages are applied to the at least two piezoelectric portions, wherein outer edges of entirety of the at least two piezoelectric portions are fixed to the fixed body.

Piezoelectric driving device, optical member driving device, camera device, and electronic apparatus

Provided are a piezoelectric driving device, an optical member driving device, a camera device, and an electronic apparatus, which are capable of performing driving only by one-direction oscillation modes, and capable of combining the oscillation modes to enable driving in two directions. A piezoelectric driving device () includes: a driving portion () to be brought into frictional contact with an object to be driven; and two piezoelectric portions () (), which are provided to the driving portion (), are arranged on a plane with the driving portion () being sandwiched between the two piezoelectric portions, and are configured to be bent with respect to the plane when voltages are applied thereto. Further, a piezoelectric driving device () includes: a driving portion () to be brought into frictional contact with an object to be driven; and at least four piezoelectric portions (to), which are fixed to the driving portion (), are arranged in a circulated manner on a plane and around the driving portion (), and are configured to be bent with respect to the plane when voltages are applied thereto.
