機等の原稿サイズ検知装置。[Scope of Claim for Utility Model Registration] (1) The contact glass on which the original is placed is irradiated from the inside of the copying machine, and the reflected light is guided to a solid-state image sensor to detect the original size. In the apparatus, a white sheet with slits is attached to the lower surface of the contact glass on the document positioning end side, and only the upper part of the contact glass surface directly above the surface of the contact glass to which the white sheet with slits is attached is fixedly imaged. A document size detection device for a copying machine, etc., characterized in that the background provides black information to an element. (2) The document size detection device for a copying machine or the like according to claim 1, wherein the background giving the black information is a space due to the absence of a document table cover. (3) The document size detection device for a copying machine or the like according to claim 1, wherein the background giving the black information is a mirror surface provided at an end of the document table cover. (4) The document size detection device for a copying machine or the like according to claim 1, wherein the background giving the black information is a black surface provided at an end of the document table cover. (5) The document size detecting device for a copying machine or the like according to claim 1, wherein the white sheet with slits is attached to two sides: a document leading edge positioning guide side and a document side positioning guide side. (6) The document size detection device for a copying machine or the like according to claim 5, wherein black and white information about only one of the two sides is analyzed.
