Swing-driven solid-state image sensor
First Claim
1. An image sensing device comprising:
- solid-state image sensor means for receiving incoming image light to produce an electrical image pickup signal;
swing-driver means for vibrating said image sensor means on a plane substantially perpendicular to the image light and for causing said image sensor means to perform an image pickup operation in such a manner that said image sensor means periodlcally shifts to different sampling positions at different time periods in one frame period with said swing-driver means comprising a pair of plate-like piezoelectric elements which face each other and stably support said image sensor means on facing side surfaces thereof;
package means for sealing said image sensor means and said piezoelectric elements, said package means comprising,elastic support means for elastically mounting said piezoelectric elements in said package means and hence allowing swinging of said piezoelectric elements at a minimum vibration loss, said elastic support means being electrically conductive and connected with said pair of piezoelectric elements to serve as electrodes for supplying a drive voltage to said piezoelectric elements.

Abstract
According to an image pickup device, a swing-driver unit is provided for vibrating an image sensor unit, thereby causing the image sensor unit to perform an image pickup operation in such a manner as to periodically shift to different sampling positions at different time points in one frame period. The swing-driver comprises a pair of plate-like bimorph piezoelectric elements for stably supporting the image sensor unit. The image sensor unit and the piezoelectric elements are sealed in a ceramic frame body in a compact manner. The electrical connection between the image sensor unit and lead wires formed on the frame is performed by a flexible film connector. The electrical connection between the piezoelectric elements and the lead wires is performed by wiring patterns preformed on the frame.
