Abstract
A document scanning device includes an index lever for indicating a boundary between a plurality of areas dividing a document on a platen and a photoelectric detector for detecting the position of the boundary. The index lever includes a marker which gives information about the boundary to the detector and a lever which moves the marker between a detectable position where the detector can detect the marker and a non-detectable position where the detector cannot detect the marker. The document scanning device is effective to be applied to a copying machine equipped with an editing function of the document.
