摘要: A copying machine which can image the upper side or underside of an original onto a photosensitive surface. The is placed copyboard between two copyboards, and projection system for integral imaging such comprises units one images other original. switchover device, may constitute component units, provided to select that be imaged. Alternatively, device activates lamps illumination
