PROBLEM TO BE SOLVED: To eliminate the necessity for setting a document to be read-out to prevent the document from being left behind by reading an image of the document on a display screen of the display portion by an area sensor independently of image reading on a document platen, and to prevent the document on the display portion from being erroneously read even if the document set on the document platen extends beyond the document platen and is laid over the display screen in a document reading apparatus having a document reading part reading an image on the document set on the document platen. SOLUTION: When detecting the document on the platen and detecting that an object on the screen of the display portion 401a does not have a standard size by the area sensor 401b, a control portion (exemplified by a main CPU 101) of the document reading apparatus controls so that the document reading portion 300 reads the image of the document on the platen and the area sensor 401b is prohibited from reading the image of the document.
