Abstract
PURPOSE:To achieve easy design of optical system, by using a viscous and elastic body processed in an elliptic ring or a circular ring as a support member of the optical system. CONSTITUTION:An object 1 to be driven is provided with an electromagnetic means such as a coil to drive the object in three directions and an optical system having at least one lens. one of two lengthwise parts of supports 4-1, 4-2 processing a viscous and elastic body such as rubber into an elliptic ring is fixed to the said body 1 and another part is fixed to a frame 2. Thus, the body 1 can freely be moved even if it is driven from a standstill position to any direction.
