Abstract

PURPOSE: To prevent the shadow of the sensor window, which is formed on the white reflective plate arranged in the back of originals in the original exposure part, from being thrown over the copy seat, by providing a shutter to shield this sensor window as required.
CONSTITUTION: Original 2 is carried while interposed between carrying belt 10 and original platen glass 17 and is detected by original detection sensor 411 in the position approximately 200mm before stopper 18. Since this detection sensor is provided on white reflective plate 29 above the belt, the white reflective plate is provided with a window. If this window is left open, the form of the window is projected onto the copy paper for thin original or high-permeability originals. Then, a shutter to close this window at the exposure time is provided to prevent the form of the window from being projected to the copy paper. Thus, the shadow of the window can be prevented from being thrown to the copy paper.
