A driving device, and more particularly, a lens driving device, for transporting a lens of an optical instrument via separate actuation of the lens itself includes guide elements connected perpendicularly with the lens for guiding reciprocating movement of the lens. The device further has driving elements arranged coplanar with the lens and fixed by a first end to a periphery of the lens for providing the lens with a transport force which is larger than an interactive force between the lens and the guide elements.
