PURPOSE:To obtain sharp copies by increasing exposure and moving a developing electrode apart from a drum when copying a three-dimensional object. CONSTITUTION:When the internal organs A are put in a tray 1 and the tray is placed on exposure glass 3, a three-dimensional object mode changeover lever 54 is pushed, and an arm 53 presses a wire 52 to turn a light shielding plate 5, thereby increasing exposure. It is equally good to increase the output of an exposure lamp at the same time. If at this time a developing electrode 81 is moved aparts from a drum 6, the sharp copy of an intensified edge effect is obtained. In the case of copying of an ordinary original, the arm 53 does not operate, and densities are controlled with a density control level 51. |
