<P>PROBLEM TO BE SOLVED: To provide a lens barrel capable of reducing collision noise between lens frames. <P>SOLUTION: A lens barrel has a first state, in which electric power is supplied from an electric power source, and a second state, in which the electric power is not supplied from the electric power source. The lens barrel comprises: at least one first lens; at least one second lens; a first lens frame holding the first lens in a movable manner in a first sphere in the first state; and a second lens frame holding the second lens in the movable manner in a second sphere in the first state. In the second state, the second lens frame is disposed within the first sphere, and a sphere, in which the first lens frame can be moved, is limited by the second lens frame. <P>COPYRIGHT: (C)2012,JPO&INPIT |
