ABSTRACT:
A setup apparatus constructed separately from an image scanning and recording apparatus. Light from a document is received by a pickup lens disposed above the document, and is branched by suitable optics. One of the branched incident beams is projected to a focusing screen disposed adjacent the pickup lens for displaying an erect image of a setup position. The other beam is passed through an aperture disposed at an optically equivalent position to the focusing screen, from which density level of the setup position is measured for display on a density indicator.
