A small-sized camera is provided to prevent deformation of a leaf spring by preventing floating of a lens holder by coupling the lens holder with a fixing unit, using high-viscosity fluid. A lens group(50) includes plural lenses for varying the zooming ratio of a displayed image of an object. The lens group is mounted on a lens holder(55), which drives the lens group in an optical axis direction. A leaf spring(65) is supported at a fixing unit(60) and guides the lens holder. Viscous fluid couples the fixing unit with the lens holder. A magnet(70) is fixed on one of the fixing unit and the lens holder. A coil(72) is fixed on the other and exposed to a magnetic field, which is generated by the magnet. The coil is wound, so that a driving force is generated when a current is applied to the coil. A magnetic unit(74) is fixed with the coil and floats the lens holder to a predetermined position. An image sensor(80) takes an image of the object. A controller controls the coil and the image sensor.
