Color drift adjusting method of two-color copying machine

Abstract

Abstract PURPOSE:To simplify the color drift adjustment by displacing only one mirror to perform the color drift adjustment in a bicolor copying machine. CONSTITUTION:A mirror frame 200 is provided with not only receiving parts 200a-200c for a half mirror 2 or a mirror 110 but also receiving parts 200f- 200h, which position a mirror 3 provided in the optical path of the reflected luminous flux of the half mirror 2, and receiving parts 200d and 200e which position a mirror 4. A receiving face I of the half mirror 2, a receiving face II of the mirror 3, and a receiving line III of the mirror 4 are determined by these receiving parts; and individual receiving parts can be worked in parallel completely when the single mirror frame 200 is set to the working base of a machine tool to work individual receiving parts simultaneously. Since intersections of reflecting surfaces of three mirrors 2-4 are parallel with one another, only one mirror 5 is displaced to perform the color drift adjustment safely.
