ABSTRACT:
A scanning projection device in which a first plane is scanned by a light deflector provided between the first plane and a second plane and partial surfaces of the first plane scanned by the deflector are successively projected at a predetermined position on the second plane. A projection optical system is disposed between the deflector and the second plane and in the plane of deflection in which the light beam from the first plane is deflected by the deflector, the projection optical system is swung and tilted in synchronism with the deflecting action of the deflector, and the deflector and the projection optical system are moved while varying their relative distance in synchronism with the deflecting action of the deflector.
