PURPOSE:To attain the copy of a stereoscopic object by a light screen on a parallel face of the Y-Z plane on an object to be copied by means of light from plural light sources, forming the image of a reflected light from the object to be copied on a CCD and storing it after photoelectric conversion. CONSTITUTION:The object 2 to be copied on a placing plate 1 is irradiated from light sources L1-L3 located in three directions. The light from these light sources forms a light screen on the object 2 to be copied, this screen is formed as a face in parallel with the Y-Z plane of the coordinate system and reflected on the object 2 to be copied. The image of the reflected light is formed on the CCD by a lens 3, converted into an electric signal, stored in a storage circuit via an operating circuit and extracted as an image signal. Thus, the entire stereoscopic body or an optional cross section of it is copied.
