ABSTRACT:
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.
