PURPOSE:To prevent image fogging at the part of additional information copied together with an original image by arranging a display part consisting of electroluminescence and transmission type liquid crystal on the reverse surface of a scale plate provided to a mount part for original information. CONSTITUTION:The scale plate 25 is mounted on the left end of an original glass plate 2, and the display part 26 consisting of liquid crystal is arranged between the scale plate 25 and an original glass table 2. The display part 26 consists of a transmission type liquid crystal part 76 positioned on the top surface of the original glass table 2 and EL (electroluminescence) 77 provided on its top surface. When an optional display is made on the liquid-crystal part 76, the EL77 on the top surface is also powered on and light from the EL77 is transmitted through the transmission type liquid-crystal part 76 to perform exposure, so the fogging of a copy image due to the ground color of the transmission type liquid-crystal part 76 is caused. |
