Abstract
An apparatus and a method adapted to be used in manufacturing an image scanning apparatus for calibrating a reflective lens on a carriage are disclosed. A calibrating device has thereon a first set of three projective points from three point light beams and a first set of three calibrating points corresponding to three point light sources. The calibrating device further includes thereon a second set of three projective points and a second set of three calibrating points for matching each of the projective points on the calibrating device with a corresponding one of the calibrating points by adjusting an angle and a position of the reflective lens on the carriage so as to achieve a calibrating function.
