Patent ID: 7864448

Claim:
A lens device comprising: a seat unit having an image sensing component with an optical axis disposed thereon; a first barrel unit movable relative to said seat unit along the optical axis between an extended position, where said first barrel unit is distal from said image sensing component, and a retracted position, where said first barrel unit is proximate to said image sensing component; a first lens module coupled slidably to said first barrel unit and having a first lens unit, said first lens module being movable in radial directions relative to the optical axis between a first shooting position, where said first lens unit is aligned with said image sensing component along the optical axis, and a first retreating position, where said first lens unit is misaligned with said image sensing component relative to the optical axis; a first guide mechanism provided on said seat unit and said first lens module for driving movement of said first lens module from the first shooting position to the first retreating position when said first barrel unit moves from the extended position to the retracted position; a first biasing unit coupled between said first barrel unit and said first lens module for biasing said first lens module to the first shooting position; a second lens module mounted pivotally on said seat unit, having a second lens unit, and rotatable between a second shooting position, where said second lens unit is aligned with said image sensing component along the optical axis, and a second retreating position, where said second lens unit is misaligned with said image sensing component relative to the optical axis; a second guide mechanism provided on said first barrel unit and said second lens module for driving rotation of said second lens module from the second shooting position to the second retreating position when said first barrel unit moves from the extended position to the retracted position; and a second biasing unit coupled to said second lens module for biasing said second lens module to the second shooting position.
