Abstract
A device for positioning a movable reflector of an optical system of an electrophotographic copying apparatus for forming an optical image of an original on a photosensitive member is disclosed wherein the movable reflector is secured to a reference plate supported by a bracket pivotally mounted on a housing which has a plurality of positioning stoppers. The reference plate supporting the reflector has a plurality of reference surfaces. Contact is made between each of the surfaces and a corresponding one of the positioning stoppers in a predetermined position. Plate springs are mounted between the reference plate and the bracket so as to absorb shock which is produced when the reference surfaces on the reference plate are brought into contact with the respective positioning stoppers. The plate springs further perform the function of positively forcing the reference surfaces on the reference plate against the respective positioning stoppers.
