    • An adjustable mounting and driving device is disclosed for a polygonal mirror to be mounted on a drive shaft. The mirror is held at an axial end in a cup shaped cavity in a holder having a central bore for receipt of the drive shaft. The bore has a drive shaft contact area which is relatively axially short allowing the housing to tilt on the drive shaft. A plate is fixably mounted on the drive shaft axially adjacent the holder and has a plurality of axially adjustable set screws engageable with a back wall of the holder to control tilt of the holder on the shaft. A resilient member between a front wall of the housing and an extension of the plate urges the housing into contact with the set screws and rotatably drives the mirror.
    • 公开了一种用于安装在驱动轴上的多面镜的可调安装和驱动装置。 镜子保持在具有用于接收驱动轴的中心孔的保持器中的杯形腔的轴向端部。 孔具有驱动轴接触区域,其相对轴向短,允许壳体在驱动轴上倾斜。 板固定地安装在驱动轴上,轴向邻近保持器,并且具有多个可轴向调节的固定螺钉,其可与保持器的后壁接合,以控制支架在轴上的倾斜。 在壳体的前壁和板的延伸部之间的弹性构件促使壳体与固定螺钉接触并可旋转地驱动反射镜。
