    Abstract: A scanning module of the present invention includes a light source for illuminating a document. Light reflected by the document is incident to a first and a second mirror provided in a pair. The two mirrors reflect the light a plurality of times therebetween and then output it as light reflected from the first mirror. Subsequently, a third and a fourth mirror sequentially reflect the light along a path including a lens. A fifth mirror reflects the light incident thereto from the lens. A linear sensor is spaced from the fifth mirror by a preselected distance such that the light passed through the lens is focused on the linear sensor. The first and second mirrors are adjustable in position on a path, extending from the document to the first mirror, while maintaining a positional relation therebetween.
