Abstract

PURPOSE:To guarantee the accuracy of a gap between a conveying belt and platen glass, by constituting a frame so as to be flexible, and making the frame match platen glass when the frame has been placed on the original platen glass. CONSTITUTION:A frame 48 for holding a driving roller 13 and a conveying belt 15 is formed by a plastic material so as to be flexible, and it placed on original platen glass 47 through location rubber 49 consisting of a rubber material. The frame 48 is deformed by its own weight, and a gap between the frame 48 and the platen glass 47 is guaranteed by thickness of the location rubber 49. Accordingly, when the accuracy of thickness of the location rubber 49 is guaranteed, gap between the conveying belt 15 and the platen glass 48 is guaranteed, and it is kept constant.
