摘要： In a lens driving device, a rack gear portion is used as a gear portion so that the gear portion can be disengaged from the terminal end of the lead screw in the radial direction. To efficiently utilize a guide shaft formed with high precision, the guide shaft extends through a spring supporting frame of a lens holder that holds a lens, a movable member having the rack gear portion that meshes with the lead screw, whereby the movable member and the lens holder are linearly guided along the guide shaft, and the guide shaft also serves as the rotation axis of the movable member. A compression coil spring is wound around the guide shaft, and the rack gear portion is pressed against the lead screw by using the compression coil spring.

摘要： A driving apparatus includes a piezoelectric element which expands and contracts when a voltage is applied thereto, a driving shaft fixed to one end of the piezoelectric element in an expanding-and-contracting direction, a friction part frictionally engaged with the driving shaft, a lens holder moved along a direction of an optical axis of a lens, and a direction-changing unit which reciprocates the lens holder in the front-rear direction along the optical axis. The direction-changing unit includes a translation cam mechanism including a moving member and a moved member, and converts a linear movement along the expanding-and-contracting direction into a linear movement along the direction of the optical axis.
