ABSTRACT:
The present invention provides an optical scanning device that prevents a disadvantageous increase in device size. Transfer optical system17includes at least concave mirrors19and20. Furthermore, transfer optical system17allows a light beam scanned by scan mirror16to enter the scan mirror again at least via concave mirrors19and20. Then, scan mirror16scans and emits the laser light beam received via concave mirrors19and20, to a plane of projection.
