PURPOSE:To prevent an error in copying and an original from being left by covering the reverse surface with transparent films normally and with a white sheet only in copying operation. CONSTITUTION:A roller 5 is driven by a motor 7 and the white sheet 3 is wound around the roller 5. A roller 6 is driven by a motor 8 in copying operation to wind the roller 6 with a transparent film 4b. Therefore, an original set with a film 4a in contact is viewed from above an original pressure plate body 1 normally through the transparent films 4a and 4b completely, and the top surface of the transparent film 4a is covered completely with the white sheet 3 in copying operation. |
