Abstract

PURPOSE: To enable the handling of the originals and other processing with ease by forming an optical scanning body by a belt-from body in the direction rectangular to the scanning direction and constituting the same separately from the original retaining transparnt plate in the copying apparatus which disposes the original with its front side being faced upward and optically scans the same downward from above.
CONSTITUTION: An original retaining transparent plate 4 is made openable by a handle 13 with the guide rail 8 side being axis. The original is retained directly from above by the transparent plate 4. An optical scanning body 5, which is built-in with a lighting lamp 14, reflecting shade 15 and scanning mirror 16, moves in the B direction along the guide rail 8 and resets to the specified position rightward from the right side edge of the transparent plate 4 then stops there when no copying work is done. Hence, only required at the time when the original is placed is to open and close the transparent plate 4 alone. The scanning body 5 is disposed transversely across the transparent plate 4 and moves in the A direction to scan the original downward from above the transparent plate 4. The scanning image of the orignal is refracted rightward by a mirror 16 parallel to the plane of the transparent plate 4 and is thereby transmitted.
