項１記載の原稿サイズ検知装置。[Scope of Claim for Utility Model Registration] 1. An exposure lamp that illuminates a document placed on a document table, and an imaging optical system consisting of a mirror and a lens that guides reflected light from the document onto a photoreceptor surface to form an image of the document. What is claimed is: 1. A scanner apparatus comprising: a document size detection device comprising: a document size detection sensor disposed at a position where reflected light from the document can be detected through the mirror; 2. The document size detection device according to claim 1, further comprising a bandpass filter movably provided in front of the optical sensor so as to double as a document density detection device.
