特徴とする原稿サイズの検知装置。In a device that obtains the image information of a document as an electrical signal using a photoelectric conversion element and treats this as a digital signal, a document size detection circuit is installed in parallel with the signal processing device that processes the image information, and is connected to the paper selection circuit. At the same time, when inputting data in the main scanning direction and sub-scanning direction to the document size detection circuit, black information of the shadow generated at the edge of the document by the illumination lamp is input, and the edge of the document is determined based on this black information. A document size detection device characterized in that it is capable of detecting an interval between document sizes.
