PURPOSE:To enable reciprocative scanning at 2 times by copying instruction at a time, by providing an intermediate return switch in the center of exposure scanning of an original. CONSTITUTION:In an optical system moving type slit exposure unit with its light source 8 reciprocatively scanning still original face 2, light source 8 scans going from first home position switch HPSW1 to A3 return switch A3SW, and returning from here in an orginary mode. In a 2 original copying mode, it scans going from switch HPSW1 to A4 return switch A4SW of an intermediate switch, returning a little to HPSW2, again going to A3SW, and returning, thus permitting 2 sheets of originals to be copied on separate sheets of transfer paper by copying instruction only at one time. |
