Title:
PIEZOELECTRIC ACTUATOR, DEVICE FOR MOVING IMAGING ELEMENT AND IMAGING APPARATUS EMPLOYING IT
Document Type and Number:
Japanese Patent JP2006121769
Kind Code:
A
Abstract:

To realize a piezoelectric actuator, suitable for size and weight reduction and advantageous in aspects of mechanical durability and manufacturing cost, with which a large object, such as an imaging element, can be driven in a predetermined direction with high output, without being accompanied by rotational deviation and a large amount of movement can be ensured.

Intersection units, each comprising a pair of bimorph piezoelectric elements (21a, 21b and 21c, 21d) intersecting in X-shape, are stacked in two stages (even-numbered stages) and are secured mutually thus obtaining a piezoelectric actuator having a balanced mechanical structure. An imaging element 11 is stably supported by two movable ends (C-1, C-2) at the tip of the piezoelectric actuator.
