LENS DRIVING DEVICE
Document Type and Number:
Japanese Patent JP2006091892
Kind Code:
A
Abstract:
To provide a lens driving device which is able to increase displacement without restriction, does not require a complex mechanism despite having a low power consumption, solves problems of friction and noise occurring in a gear part and is suitable for miniaturization and lightness.
The lens driving device includes a substrate which generates surface acoustic waves, and a movable part on which an optical lens is mounted and which executes translation above the substrate in a direction opposite to the advancing direction of the surface acoustic waves.
