PURPOSE:To control the occurrence of double blur and at the same time, enable easy writing by recording a mirror image of a reflective copy image to a transparent sheet based on signals from a reader and creating a secondary copy for an overhead projector. CONSTITUTION:An overhead projector is equipped with a reader 7 which reads an image from a primary copy 6 to be placed on a body base 1 for duplication. Further, a recorder 9 records a mirror image of the image from the primary copy 6 on a transparent sheet 8 based on a signal transmitted by the reader 7. Next, the recorder 9 duplicates the mirror image to prepare the secondary copy 3. The secondary copy 3 is a normal erect image which is the same as the primary image as viewed from the side of a projection lens 31. Consequently, it is possible to project the same image as the primary copy 6 on a screen by causing a lamp of a projection head part 4 to emit light. For this reason, the secondary copy 3 is placed on a reflective Fresnel plate 2 maintaining a recording layer 3a of the former turned outside in. Thus the recording layer 3a is brought closer to the reflective Fresnel plate 2. |
