ABSTRACT:
A photographic reproportioning apparatus for transferring an image from a sheet member to an arcuate image on a photosensitive sheet has first and second travel boards movably supported for movement in a linear direction. A light shield having a uniform exposure line and a taper exposure line is located over the travel boards. Light projected through one of the exposure lines exposes a photosensitive sheet on movement of the sheet under the exposure line. A radius attachment having a circular member is drivably associated with the second travel board to move a photosensitive sheet in an arcuate direction. The sheet member carrying the image is attached to the first travel board and moves in a linear direction whereby the linear image is projected by light passing through the tapered exposure line in an arcuate pattern on the photosensitive sheet as the photosensitive sheet and sheet member having the image pass under the tapered exposure line.
