摘要： A high-magnification zoom lens having a lens system that is movable from a wide angle setting to a telephoto setting includes five lens groups. The lens system has a focal length of fW in the wide angle setting and a focal length of fT in the telephoto setting. The five lens groups are arranged in order from an object side along an optical axis that extends from a center of the lens system. A first lens group G1 has a positive refractive power and a focal length of f1, a second lens group G2 has a negative refractive power and a focal length of f2, a third lens group G3 has a negative refractive power and a focal length of f3, a fourth lens group G4 has a positive refractive power, and an image composing lens group GR has a positive refractive power. When the lens system changes from the wide angle setting to the telephoto setting, the first lens group G1 and the fourth lens group G4 move such that a distance between the first lens group G1 and the second lens group G2 increases, a distance between the third lens group G3 and the fourth lens group G4 decreases, and several conditions are satisfied.

摘要： A general-purpose system for enabling the user to easily enter characters whose contents are hard to understand at a glance, such as bar codes, by using a general-purpose application program such as a wordprocessor is provided. For this purpose, a printer driver comprising a font file storing a display font and a bar code record font corresponding to the display font and a conversion function of converting display font codes into record font codes is provided. When a bar code is entered in an application program, a legible display font corresponding to the bar code can be used. On the other hand, when the bar code is printed, the printer driver compatible with a given printer converts the display font into a bar code record font and supplies the bar code record font. Thus, a high-accuracy bar code is printed in accordance with the standard.

摘要： A zoom lens includes at least two lens groups, i.e., a first lens group and a second lens group. The second lens group includes a first sub-group near to the first lens group and a second sub-group far from the first lens group, and the first lens group and the first sub-group in the second lens group together form a substantially afocal system in at least a portion of a zooming range. In the zoom lens, focusing is effected by the first sub-group in the second lens group being moved along the optical axis. Considering a case where this zoom lens is applied for auto focusing, it is preferable that the first lens group be disposed on that side in the lens group which is most adjacent to the object side.

The zoom lens comprises a shift means for moving one of the third and fourth lens groups G.sub.3, G.sub.4 perpendicularly across the optical axis.
