ABSTRACT:
A copier for copying documents, drawings and similar originals onto paper has a window for supporting an original. A source of copying light is located below this window. The copier has a light source, advantageously the source of copying light itself, which is capable of being activated independently of the copying operation so that the original may be transilluminated without intiating the copying operation. This makes it possible to precisely position the original before the actual copying operation. A slidable or superimposable mask or the like may be provided between the light source and the original in order to display orientation symbols on the transilluminated original.
