Abstract: A zoom lens includes a first lens group with a negative refractive power, a second lens group with a positive refractive power, and a third lens group with a positive refractive power. When the zoom lens changes from a wide angle end to a telephoto end, a spacing between the first lens group and the second lens group is reduced, and a spacing between the second lens group and the third lens group changes. The first lens group includes a first lens, a second lens, a third lens, and a fourth lens. Refractive powers of the first lens, the second lens, and the third lens are negative, and a refractive power of the fourth lens is positive. Abbe numbers of the first lens, the second lens, and the third lens are larger than 60. A ratio of a focal length of the first lens group over a focal length of the zoom lens at a wide angle end is larger than ?2.5 and smaller than ?1.2.

Abstract: A voltage transform part transforms the direct-current power input to an input part. A first input and output part outputs the transformed direct-current power to a battery unit and to which direct-current power is input from the battery unit.

The conversion part converts the alternating-current power input to the second input and output part into direct-current power. The second voltage transform part transforms the direct-current power converted by the conversion part and transforms the direct-current power input to the first input and output part. The conversion part converts the direct-current power transformed by the second voltage transform part into alternating-current power.
