Abstract

A photographic printer makes enlarged elemental prints of portions, into which a single image frame of an original film is divided, and used to make a large size picture display. There are provided a film holder, movable in two dimensions; a position index panel with a plurality of possible positions corresponding to the portion for positioning the film holder to align the center of each portion with the printing axis of the photographic printer; a position indicating panel with a plurality of position indicating light emitting elements for selectively indicating a position where the film holder is to be placed; and an indicating member which is movable over the position indicating panel. The light emitting elements indicate the corresponding possible positions of the positioning panel. When aligning the indicating member with a light emitting element which is now emitting light, the film holder is placed in position so as to print a portion of the image frame to be printed into the printing position.
