ABSTRACT:
An image of the original document is read rapidly to effect quick production of the first copy even when the function of the shading correction and the function of the color/monochrome judgment operate. A waiting position P2 of a first slider 211 is located on the opposite side from a scan starting position P3 in reference to a reading area for the original document, and a location of a shading correction plate 206 is interposed between the reading area for the original document and the waiting position P2 of the first slider 211. While the first slider 211 is in the process of returning from the waiting position P2 to the scan starting position P3 for the preparation of reading the image of the original, a shading correction and a color/monochrome judgment are carried out for preventing the first slider 211 from having extra motion.
