Abstract
PURPOSE:To obtain a copy with constant contrast at the same position of an original drawing selecting dial when the same original drawing is used even if a sensitive paper is changed by changing the characteristics of speed change according to the sensitivity of these sensitive papers in a diazo copier which changes its printing speed on the basis of the shading of the original drawing. CONSTITUTION:When an original drawing selecting dial 3 is changed in consideration of the shading of the original drawing or a required copying contrast, the value of a variable resistance 2 in the speed change controlling part 6 of a feed motor M is changed to change the printing speed. When a sensitive switch dial 4 is changeovered according to the kind of sensitive papers, an input controlling part 7 is switched and the characteristics of speed change in a speed change controlling part 6 is changed, so that copies with constant contrast are obtained from the same original drawing when the original drawing selecting dial 3 is set to the same scale 5 even if sensitive papers with different sensitivity are used.
