Abstract:
1. A lens barrel unit with a lens barrier comprising: barrier members that pivotally move about an axis extending parallel with an optical axis, for opening and closing a photographic opening; rotary shafts each respectively connected to corresponding one of said barrier members and extending coaxially with the axis of said barrier members about which said barrier members pivotally move; a driving member that applies a driving force to each of the rotary shafts, for shifting said rotary shafts to pivotally move the barrier members; and a lens holding member having a lens and through holes formed therein, through each of which one of said rotary shafts is rotatably inserted, wherein: each of said rotary shafts has an integrally formed driven part to which the driving force is applied from said driving member to pivotally move the respective barrier member, said rotary shafts being shifted for rotation by the driving force transmitted to the respective driven parts; and said lens holding member is disposed between said barrier members and said driven parts of said rotary shafts.
