Abstract:
1. A device with a lens-rotation mechanism, comprising: a casing; a lens-rotation system mounted in said casing and including an optical module and at least two transmission elements coupled to said optical module, said optical module including a lens and a flashlight, each of said two transmission elements being an arcuate gear rack, a first of said arcuate gear racks being pivotally coupled to said optical module by a pair of rotation members, a second of said arcuate gear racks being coupled to said optical module orthogonally with respect to said first arcuate gear rack; and a driving device including a first motor and a second motor, said second motor being operatively coupled to said second arcuate gear rack for driving said second arcuate gear rack to rotate said optical module about an axis defined by said pair of rotation members, said first motor being operatively coupled to said first arcuate gear rack for driving said first arcuate gear rack to rotate said optical module and said second motor about an axis orthogonal to said axis defined by said pair of rotation members.
