Abstract
A mechanical, electrical and optical scanning apparatus for producing a digital image of a two-dimensional original object that can be either opaque or transparent. A platform supports a camera with precision zoom/focus control for receiving light energy from the object, and the light is converted into electrical energy in a digital format. Opaque objects are supported separately from transparent objects on a carriage, and a light source is supported pivotly for illuminating these objects during scanning in a different manner.
