PURPOSE:To assemble the frame of a copying machine easily and accurately without using any jig, etc., by providing side plates or a bottom plate with projections and the other with hole parts accurately. CONSTITUTION:The side plates 3 and 4 are provided with embosses (half blanking) of strict dimension accuracy and the bottom plate 1, on the other hand, is provided with holes where said embosses are fitted at bent parts which contact the side plates. A copying machine support structures such as a lens 5, photosensitive drum 6, fixing roller 7, and developing device 8 by the side plates 3 and 4, which are propped by the bottom plate 1. Said constitution allows an accurate common axial core between the side plates 3 and 4 in order to install said structures in the frame. |
