装置。 A scanning member equipped with a light source and a reflecting mirror for scanning an original on an original platen glass is provided with at least two optical sensor elements each having a light emitting element and a light receiving element, one of the optical sensor elements being located at the center of the scanning member. The other optical sensor element is arranged at a side part having a predetermined interval from the center of the scanning member to detect the width direction of the original. The present invention is characterized in that a switch means is provided at an end of the document table to recognize the document size by being actuated by the closing operation of the document pressure plate cover to cause the scanning member to perform an empty scan and to operate the optical sensor element. A document size detection device in a copying machine.
