An optical scanner capable of preventing breakage of a shaft section due to stress concentration is provided. A mirror frameis shaped so as to enclose a mirror, and holds the mirror, via torsion barsand, so as to be vibratable. A unimorphis constituted by four unimorphs, andformed on upper left, lower left, upper right, and lower right sides, and holds the mirror frame, via a shaft section, so as to be vibratable. The shaft sectionhas a connection section. On the mirror frame, an adjustment memberfor increasing a moment of inertia mof the mirror frameis provided.

A driving device is adapted to drive a driven member, and includes a driving member, and a linear shape memory alloy (SMA) actuator. The driving member has a displacement output portion which is movable in a first axis direction, and a displacement input portion for moving the displacement output portion in the first axis direction in response to an application of a moving force in a second axis direction orthogonal to the first axis direction. The driving member is engaged with the driven member at the displacement output portion. The SMA actuator is disposed in contact with the driving member at least at the displacement input portion to apply the moving force to the displacement input portion.

Driving device, driving mechanism, and image sensing apparatus

An image pickup device wherein the range in the amount of incident light (dynamic range) for obtaining an appropriate image can be expanded, and shutter and aperture functions are provided. A light shielding element for light shielding a photoelectric conversion section and an actuator for driving the light shielding element are provided on the pixel of the image pickup device using the MEMS technology, and the amount of light shielding is controlled for each pixel, whereby the dynamic range is expanded, and shutter and aperture functions are also provided.
