<P>PROBLEM TO BE SOLVED: To provide a lens barrel enabling a structure for shielding an optical path during power source OFF without interrupting downsizing of an entire camera system. <P>SOLUTION: A lens barrel having a vibration-proof mechanism includes: a shift drive regulation member for regulating and deregulating transfer of the vibration-proof mechanism; at least one shading blade that is inserted/removed on an optical axis to open/close an optical path; shift regulation detection means for detecting regulation and deregulation states of the vibration-proof mechanism; and shading blade detection means for detecting the state of whether the shading blade is inserted or not. The insertion/removal mechanism of the shading blade is configured in the shift drive regulation member. The shift drive regulation member can insert/remove the shading blade under a regulation state. The shift drive regulation member makes it possible to switch between regulation and deregulation states under a state in which the shading blade is not inserted. <P>COPYRIGHT: (C)2013,JPO&INPIT |
