Zusammenfassung:An actuator for continuous zoom according to an embodiment of the present invention includes: a first carrier on which a first lens is mounted and which moves in an optical axis direction; a housing for accommodating the first carrier; a first magnet provided on the first carrier; a first coil facing the first magnet and having a track shape; a plurality of first hall sensors provided outside the track shape of the first coil and detecting the position of the first magnet; and a driving driver for controlling power applied to the first coil by using signals input from the plurality of first hall sensors. Therefore, the driving precision of feedback control processing can be improved. 본 발명의 실시예에 의한 연속줌 액추에이터는 제1렌즈가 탑재되며 광축 방향으로 이동하는 제1캐리어; 상기 제1캐리어를 수용하는 하우징; 상기 제1캐리어에 구비되는 제1마그네트; 상기 제1마그네트와 대면하며 트랙 형상을 가지는 제1코일; 상기 제1코일의 트랙 형상 외측에 구비되며, 상기 제1마그네트의 위치를 감지하는 복수 개 제1홀센서; 및 상기 복수 개 제1홀센서로부터 입력된 신호를 이용하여 상기 제1코일에 인가되는 전원을 제어하는 구동드라이버를 포함하는 것을 특징으로 한다.
