Abstract

A zoom lens apparatus with focus adjusting and an optical imaging device therewith are provided wherein a combination of screw driven ultra sonic motor and voice coil motor is adopted to drive different optical lens sets (25 61). For the ultra sonic motor the screw motion of the rotor (23) is transformed into a simple rectilinear motion by providing a third tube (24) placed in the rotor (23) and radially fixed relative to the stator (22). Thus the zoom lens apparatus with focus adjusting produced with the combination can well maintain the stability of the optical axis moreover the combination of different driving methods integrates and makes better use of lens sets of different functions and hence simplifies the overall structure.
