ABSTRACT:
A device for positioning an original in sheet form on an exposure table comprising a ruler and a means for moving the ruler between a position in which an edge of the ruler extends upwardly from the exposure table for positioning and retaining a sheet original arriving along the exposure table and a position in which the original is released so that it may be displaced in the direction of and past the ruler. The exposure table has a recessed part such that when the ruler occupies the retaining position the part of the ruler bearing the retaining edge rests partly in the recessed part such that it lies against the upright wall of the recessed part and partly projects above the surface of the exposure table.
