发明名称 Automatic density adjusting device in copying machine
摘要 In an automatic density adjusting device in a copying machine, the width of variation in exposure intensity in relation to the change in a density correction value or magnification manually set is set to a large width if a document is dark, while being set to a small width if the document is light. Accordingly, exposure intensity corresponding to the density correction value or the magnification can be increased or decreased with respect to the light document and the dark document. Consequently, it is possible to always make the most suitable automatic density adjustment irrespective of whether the document is light or dark.
