Abstract
A lens barrel with a shutter unit. While the lens barrel is retracted to obtain a collapsed state or advanced to obtain a photographing state, the flexible printed circuit board of the shutter unit is bendable so as to provide a variable length for the rotation of the shutter unitaround the rotary axis Jparallel with the optical axis J. When the lens barrel is operated in the photographing state, the flexible printed circuit board is foldable so as to provide a variable length for the movement of the shutter unitin the optical axis J. The flexible printed circuit board can support flexibly without twisting and loosening. The lens barrel further includes a restraint member to bring the shutter unitrotating around the central axis and to restrain the rotation of the shutter unit
