摘要：
The present invention provides an optical scanning device that prevents a disadvantageous increase in device size. Transfer optical system 17 includes at least concave mirrors 19 and 20. Furthermore, transfer optical system 17 allows a light beam scanned by scan mirror 16 to enter the scan mirror again at least via concave mirrors 19 and 20. Then, scan mirror 16 scans and emits the laser light beam received via concave mirrors 19 and 20, to a plane of projection.
