摘要： Black tapes 61 and 62 having optical reflectances different from that of the texture of a document D are stuck to the lower side of a platen cover 3. The black tapes 61 and 62 have the optical reflectances different from that of the texture of the document D. When the document D set on a document table 2 and the black tapes 61 and 62 are exposed by a light exposure lamp 5, at least one edge of the document D set on the document table 2 and the length of the edge are detected according to the amount of reflected light from the document D and that from the black tapes 61 and 62. The size of the document D set on the document table 2 is judged according to the detected length of the edge.

摘要： According to one embodiment, an image scanning apparatus includes a document glass, a substrate, a first semiconductor light emitting element, a second semiconductor light emitting element, a light guiding section, and a light receiving section. The substrate is provided below and obliquely opposed to the document glass. The first semiconductor light emitting element is mounted on a first surface of the substrate opposed to the document glass and emits light to an original document via the document glass. The second semiconductor light emitting element is mounted on a second surface on the opposite side of the first surface and emits light. The light guiding section receives incidence of the light emitted from the second semiconductor light emitting element and emits the light to the original document from a position where a normal of the document glass is present between the light guide section and the first semiconductor light emitting element.
