摘要：
A drive mechanism for a lens unit with a tripod mount. The tripod mount is on a stationary cylinder while the camera mount is on a rotatable cylinder which contains a drive shaft for mechanically driving a lens axially movable along the stationary cylinder. A drive gear supported by the stationary cylinder causes the linear movement of lens by its rotation. A planetary gear system, coupled to the stationary cylinder connects the drive shaft and the drive gear.
