Patent ID: 7362513

Claim:
A serration apparatus for a portable terminal having a camera lens module, comprising: a first serration gearing; a second serration gearing mounted on the camera lens module, wherein the second serration gearing receives the first serration gearing within an interior thereof and is compressed against and meshes with the first serration gearing and when the camera lens module is rotated, the second serration gearing rotates with the camera lens module and produces a frictional force against the first serration gearing, thereby creating a clicking feeling; a stopper means for limiting rotation of the camera lens module, the stopper means comprising a disc-shaped stopper member disposed on the first serration gearing and a locker member disposed on the second serration gearing, the locker member being engaged with the disc-shaped stopper member and coming into contact with the disc-shaped stopper member as the second gearing is rotated; and elastic means for providing compressing force to cause the first and second gearings to mesh with each other.
