Abstract
An electrostatic or xerographic copying apparatus of the type having a transparent support on which an original is placed face down so as to be copied through the support, has a first arrangement capable of holding first members which form with one another a gap, and a second arrangement capable of holding an original which overlies the first members so that increments of its face are visible through this gap. An arrangement is provided for shifting the second arrangement relative to the first arrangement so that different increments of the original can be exposed in the gap.
