<P>PROBLEM TO BE SOLVED: To provide a position control device for a vibration-proof insertion/separation optical element, capable of preventing a vibration-proof driving actuator from being damaged due to excessive current flowing in a vibration-proof coil and electric power from being wastefully consumed when storing and moving a vibration-proof movable frame including separating and moving a vibration-proof lens. <P>SOLUTION: When input means (61) receives a storage instruction signal, control means (60) cuts off power supply to vibration-proof coils (31, 32) and switches a vibration-proof drive actuator (26) from a driving state to a non-driving state, before the control means (60) moves advancing/retreating frames (14 and 16 or 70 and 90) from a photographic position to a storage position by a main actuator (62) and moves an insertion/separation frame (20 or 86) from an insertion position to a separation position via a separation driving mechanism (24 or 102). <P>COPYRIGHT: (C)2013,JPO&INPIT |
