摘要： A laser scanning optical apparatus wherein a plural number of beams are deflected by one polygon mirror and are scanned on respective corresponding photosensitive drums via a scanning optical system. The scanning optical system has a first scanning lens which transmits all the beams, exclusive second scanning lenses which transmit exclusively the respective beams and plane mirrors for reflecting the beams. The second scanning lenses are located such that at least one of the second scanning lenses is at a distance from the corresponding photosensitive drum on which the beam transmitted by the at least one of the second scanning lenses is scanned and that another second scanning lens is at another distance from the corresponding photosensitive drum on which the beams transmitted by the another second scanning lens is scanned. For example, at least one of the exclusive optical elements is at a distance from the corresponding photosensitive drum, and the other exclusive optical elements are at another distance from the respective corresponding photosensitive drums. Alternatively, the exclusive optical elements are at mutually different distances from the respective corresponding photosensitive drums.

摘要： A zoom lens includes, in order from an object side, a first lens group having a negative power, a second lens group having a positive power, and a third lens group having a positive power. At least the first and second lens groups are movable during a change from a wide-angle end state in which a focal length becomes shortest to a telephoto end state in which the focal length becomes longest. The first lens group is constructed of a glass lens and a plastic lens, the glass lens being positioned on the object side and having a negative power, the plastic lens being positioned on an image side and having a positive power. The second lens group includes a single plastic lens having a negative power. The third lens group includes at least one plastic lens having a positive power. The lenses are satisfied predetermined conditions.
