ABSTRACT:
A horizontal platen is translatable through a first exposure position above a photoconductive drum for supporting bulky original documents such as books. A first focussing optical fiber array is disposed between the first exposure position and the drum. A sheet feed mechanism is provided at a second exposure position for feedingly scanning original documents in the form of sheets. The second exposure position is on a circle concentric with the first exposure position and a second focussing optical fiber array is disposed between the second exposure position and the drum. The sheet feed mechanism is located below the platen. A directed light source is movable to selectively direct light to the first or second exposure position. In one form of the invention only one focussing optical fiber array is provided which is movable between the first exposure position and the drum or between the second exposure position and the drum.
