LENS BARREL

摘要

PROBLEM TO BE SOLVED: To provide a lens barrel by which the opening/closing of a barrier and the lens movement of a lens optical system are performed by a single driving source and also focusing is performed without giving disturbance even in a state where opening/closing the barrier can be performed. SOLUTION: Driving force is transmitted to a barrier opening/closing mechanism by the withdrawal of a lens barrel 1 by a specified amount or more, and the driving force is not transmitted to the barrier opening/closing mechanism by the extending of the lens barrel 1 by the specified amount or more, so that the opening/closing of the barrier and the lens movement of the lens optical system are performed by a single motor 95.
