Abstract

PURPOSE:To obtain a copy having a high contrast, by carrying out the auxiliary illumination through the rear side of a transparent original of a reflection type copying machine. CONSTITUTION:A transparent subject C is put on a transparent original mounting plate B of a reflection type dry copying machine A, and an auxiliary illuminating device 1 is put on the subject C. The device 1 contains a lamp 4 on its inner surface, and the brightness of the lamp 4 can be controlled by means of a reflecting plate 3 and a knob 6. A semitransparent plate 5 is used to the bottom surface of the device 1. The luminous intensity of the lamp 4 is controlled at the area right under the plate 5 so that the picture of the subject C can be identified. Then the copying is carried out by the device A to obtain a copy having a high contrast.
