出装置。 A recess is formed on the back side of the document cover, which covers the document moving relative to the light source for scanning the document, and whose back surface is a reflective surface, at least in a portion located at the rear edge of the document. A lamp for detecting the trailing edge of a document that emits light from diagonally forward during relative movement, and a light receiving element that receives light from the lamp for detecting the trailing edge of the document reflected at the recessed portion are arranged below the document table. A document trailing edge detection device characterized by:
