Abstract

PURPOSE:To match parallel displacement of an optical beam linearly in an auxiliary direction by making two plane reflecting mirrors opposed to each other with a fixed angle move linearly in a body. CONSTITUTION:An angle between an incident beam Bi and an exit beam Bo is relative to only an angle theta between the two plane reflecting mirrors, is independent of a direction of the incident beam. Therefore, by fixing an setting angle between plane reflecting mirrors M1, M2 and making directions of movements of the M1, M2 constant an angle delta between the incident beam Bi and the exit beam Bo and an angle epsilon between a bisector of the angle delta and the Z direction are constant and a quantity of parallel displacement of the beam DELTAX is proportional to a quantity of a movement of the reflecting mirror 1 to obtain DELTAX=21sinepsilon.cosdelta/2. This device, when in a laser printer a reflecting position of the rotating reflecting mirror is adjusted to come to the position of the pupil of a ftheta lens, is effective, and when combined with an AO modulator it is good to be made to be theta=pi/2+ or -thetaB.
