Abstract
PURPOSE:To enable the controlling of the position of the beam spot focused on the surface to be scanned and achieve simpler constitution and easier adjustment by providing an optical member which leads and focuses the beam onto the surface to be scanned, between a light source part and the surface to be scanned and moving the optical member. CONSTITUTION:The deflecting beam 23 deflected by a rotary polyhedral mirror 21 images at the point r1 of an imaging surface 24 by passing through an imaging lens 22. Next, when the imaging lens 22 is deviated by DELTAY in the direction rectangular to the deflecting beam, the deflecting beam 25 images at the point r2 of the new position on the imaging surface 24. By deviating the imaging lens 22 in the direction orthogonal to the plane to which the beam is deflected, adjustment may be made with respect to the direction orthogonal to a reference scanning line. The position adjustment of the beam is similarly possible even by disposing the imaging lens 22 between the light source part and deflector.
