PURPOSE:To move a lens barrel, having an incorporated condenser lens, in three dimensions, by supporting the lens barrel by a flexible member and driving it by an electromagnetic driving means. CONSTITUTION:An assembly 1 is a lens barrel having an incorporated condenser lens; four coils 3a-3d are stuck to the upper flank part at equal intervals, and a coil 3e is also struck stop of the lens barrel 1. So that the lens barrel 1 is capable of moving forth and back, right and left, and up and down, it is supported by flexible members 2a-2d each made of channel-shaped rubber, metal, etc. and magnets 4a-4e are inserted into the coils 3a-3e. The lens barrel 1 is moved in three dimensions by flowing currents selectively to the coils 3a-3e. |
