A scanner module includes an illumination optical unit which illuminates light to an object, a plurality of reflecting mirrors which reflect a light beam from the object and change a light path, a sensor unit which reads information about the object from the incident light beam, a focusing lens unit which is disposed between the plurality of reflecting mirrors and the sensor unit and focuses the light beam reflected from the plurality of reflecting mirrors onto the sensor unit, and a ghost image preventing unit which is formed on at least one of the plurality of reflecting mirrors and controls a ghost image from being directed to the sensor unit.
