Patent ID: 7667905

Claim:
An apparatus, comprising: at least two movable lens units, wherein each of said at least two movable lens units comprises at least two lenses, wherein said at least two movable lens units are movable into a first state wherein said at least two movable lens units are arranged in parallel to each other, wherein said at least two movable lens units are movable into a second state wherein said at least two movable lens units are arranged on top of each other for positioning each of the at least two lenses of said at least two movable lens units in a common optical axis, wherein the common optical axis extends in one direction, wherein said apparatus further comprises a lever mechanism to move said at least two movable lens units into the first or into the second state, and wherein said lever mechanism is connectable to a base member, wherein the lever mechanism comprises at least two guide shafts, wherein each of said at least two guide shafts is hinged to the base member, and wherein each of said at least two movable lens units is connected to said at least two guide shafts via a set of joints, and wherein each of the joints of said set of joints has a degree of freedom for enabling rotational movement, and wherein at least one of the joints of said set of joints has a second degree of freedom for enabling linear movement, so that said lever mechanism is capable of unfolding said at least two movable lens units from the first state into the second state and capable of folding said at least two movable lens units from the second state into the first state.
