濃度検知装置。 A slit exposure type electrophotographic copying machine is equipped with a document density detector on the image field side near the imaging lens.
The original density detector is located in a region where the reflected light beams from each point of the original document out of the slit-shaped original reflected light overlap on the image field side of the imaging lens, and are offset from the optical axis. Original density detection device for electrophotographic copying machines.
