Abstract
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.
