ABSTRACT:
A system for assisting manual placement of odd-shaped original documents on the exposure platen of a copier or scanner includes a detection device disposed on an edge of the platen. The device includes a light source emitting a light beam substantially parallel to a surface of the platen, and a photosensor adapted to detect light resulting from the reflection of the light beam by an object on the surface of the platen. A main focus direction of the light source and a main focus direction of the photosensor intersect at a predetermined position on the surface of the platen.
