DIGITAL CAMERA SYSTEM WITH PIEZOELECTRIC ACTUATORS |
摘要 |
A digital camera is constructed with multiple lenses mounted in a pair of tubular elements which are nested together for relative axial movement. Movement is provided by piezoelectric actuators mounted externally to a support tube on flexible printed circuit board elements. Each lens tube is provided with a drive rail which extends at least partially over the length of the lens tube and projects radially outward from the periphery of each of the tubes. The rails are accessible to the engagement pads of the piezoelectric actuators to allow the transmission of drive forces to each of the tubes. |
