摘要： An image reading apparatus includes a first running device that moves to scan a document at a predetermined speed, which includes an illumination unit and a first mirror; a second running device that moves in the scanning direction parallel to the first running device with half the predetermined speed of the first running device, which includes second and third mirrors; an imaging lens to produce an reduced image; and a line sensor to convert the reduced image to an electrical signal. At least one of the second and third mirrors is comprised of a spherical surface and a curvature radius of the spherical surface of such mirror is such that a distance deviation between the imaging lens and an imaging surface remains within usable range for actual operation regardless of movements of the first and second running devices.

摘要： A first group optical system having a positive refracting power, a second group optical system having a negative refracting power, and a third group optical system having a positive refracting power are sequentially arranged from an object side toward an image side. At least the first group optical system and the third group optical system move so that a distance between the first group optical system and the second group optical system becomes minimum at short focal-length side, and a distance between the second group optical system and the third group optical system becomes minimum at long focal-length side. The third group optical system includes a triplet lens formed with a negative lens, a positive lens, and a negative lens.
