Abstract

A paper mask unit for setting a paper mask in an exposure station of a photographic printer. A mask frame of the paper mask unit has a paper guide member which is movable in a direction transverse to a paper transporting direction between a paper guide position for guiding photographic paper thereon and a rest position wherein the paper guide member is retracted from the exposure station. After the photographic paper is set in the exposure station, the mask frame is displaced apart from the photographic paper. When the paper mask is inserted into the mask frame through the mask guide path, the paper guide member is pushed by the paper mask inwards from the paper guide position into the rest position. Simultaneously, a letter printing aperture of the paper mask is automatically positioned on a lamp housing which is mounted on the paper guide member. Thereafter, the mask frame is moved into a masking position so as to bring the paper mask into contact with the photographic paper. The paper guide member is urged by springs to return to the paper guide position when the paper mask is removed from the mask frame.
