    • 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.
    • 一种扫描投影装置,其中第一平面被设置在第一平面和第二平面之间的光偏转器扫描,并且由偏转器扫描的第一平面的部分表面连续地突出在第二平面上的预定位置。 投影光学系统设置在偏转器和第二平面之间,并且在偏转平面中,来自第一平面的光束被偏转器偏转,投影光学系统与倾斜器的偏转动作同步地摆动和倾斜 偏转器和偏转器和投影光学系统在偏转器的偏转动作同步地改变其相对距离的同时移动。
