ABSTRACT:
A method and apparatus for making a two-dimensional copy from either a two-dimensional or three-dimensional object is provided. In making a two-dimensional copy from a three-dimensional object, the object is submerged in the liquid contained in a container having a transparent bottom portion to which said object is brought into contact by placing a cover member thereon. The object is then exposed through the transparent bottom portion thereby the projected image of the object viewed through the transparent bottom portion is reproduced on a sheet of copy paper.
