ABSTRACT:
A photographic printer has a printing section capable of having selectively mounted therein a plurality of printing lenses with different magnifications, to form various sizes of image frames on photographic paper. The printer also includes a processing section for developing, bleaching-fixing and rinsing the photographic paper exposed in the printing section, and a cutter unit for cutting the exposed and developed photographic paper to provide separate prints. The photographic printer has a lens mounting mechanism which enables selective mounting of the plurality of printing lenses with their optical axes perpendicular to a plane onto which images are projected by the printing lenses, and with their exposure axes inclined at different angles according to their magnifications with respect to the plane.
