Abstract
A zoom lens barrel in a camera is driven by a drive motor via a zoom drive gear train and a lens barrel gear train. A finder optical system, which is interlocked with the zoom lens barrel, is driven by the drive motor through the zoom drive gear train, a finder drive gear train, a friction clutch mechanism and a finder cam. Since the finder optical system is driven via the friction clutch mechanism, a phase adjustment between the lens barrel and the finder optical system is easily performed. The camera is easily assembled without paying particular attention to zoom position deviation in the finder optical system.
