Abstract
PURPOSE: To obtain accurate copies separately on both ways of reciprocation by using two solid-state image sensing elements.
CONSTITUTION: Solid-state image sensing elements 7A, 7B which are respectively separate for forward scanning and backward scanning are arrayed in the imaging position of an imaging lens 6 and are disposed oppositely in their main scanning directions between forward and backward ways. As a result of this, the forward main scanning MS of the original surface 1 is accomplished by the solid-state image sensing element 7A which receives strip-form reflected light L and the forward sub- scanning SS is accomplished by the solid-state image sensing element 7A through movement of a reflecting mirror 5a and lighting system 3. Thence, a one-way signal processing circuit 8, plotter 9 and driving circuit 10 are changed over for backward way by the changeover signal from a control circuit 11 at the final end of the forward way and after the original 4 separate from the forward way is placed on glass 2, the backward scanning is done by the solid-stage image sensing element 7B, whereby the accurate copies which are opposite only vertically are obtained.
