ABSTRACT:
A frame for making photocopies, includes a support plate having an upper surface adapted to support photosensitive sheet material and including four edges. At least two covers are provided, for covering respective sections of the upper surface of the plate so as to prevent light penetration onto the latter. Each of the covers is pivotable independently of the other between a first position in which a respective section of the upper surface of the plate is uncovered and a second position in which the respective section of the upper surface is covered. When the covers are in the abovementioned second position, they light sealingly engage the respective edges of the plate.
