Abstract: An apparatus for previewing original positive documents and for copying the previewed documents in substantially exactly the same form as previewed with a xerographic or electrostatic copier. The positive document to be copied is placed on a transparent surface such as the glass plate of a conventional copier and is illuminated through the plate to produce an image that can be previewed and copied. In one embodiment, the previewer and copier optics are arranged so that either previewing or copying can be selectively accomplished at the same document receiving station. In another embodiment, the apparatus includes a previewing station including a screen and means for projecting documents being previewed on the screen. Documents to be copied are transferred to a copy station by a belt (e.g. a transparent belt) wherein it is copied such as by an electrostatic copying apparatus.
