Abstract
A lens barrel having an insertable/removable optical element includes an advancing/retracting member, an anti-shake frame supported by the advancing/retracting member, an insertable/removable frame holding the insertable/removable optical element and supported by the anti-shake frame, an anti-shake drive mechanism, and a removal drive mechanism which moves the insertable/removable frame between the insertion and the removed positions. The anti-shake drive mechanism includes first and second anti-shake drive actuators positioned on the opposite side of the insertion position from the removed position and are respectively positioned on opposite sides of a straight line connecting a center of the insertable/removable optical element at the insertion position and at the removed position. Directions of driving forces produced by the first and second anti-shake drive actuators are at right angles to each other.
