<p>A device for positioning an original in sheet form on an exposure table (1), comprising a ruler (5) and means (8,11,12,13) for moving the ruler between two positions, a position in which an edge of the ruler extends upwardly from the exposure table (1) for retaining a sheet original arriving along the exposure table, and a position in which that original is released in order to be displaced in the direction of and past the ruler. The exposure table (1) has a recessed part (3), in which that part of the ruler bearing the retaining edge, when said ruler occupies said first mentioned position, rests partly, and so fits therein that it lies against the upright wall (2) of the recessed part (3) and partly projects above the surface of the exposure table (1).</p> |
