PROBLEM TO BE SOLVED: To provide a scanner core structure in which a second light source and a movable lens are designed and the overall volume of a scanner can be reduced. SOLUTION: A scanner core structure includes: a movable lens which passes a first light beam during platform type scanning or reflects a second light beam incident from a second lens during sheetfed scanning; a group of lenses reflecting the first light beam or the second light beam incident from the first lens or the movable lens in order; a lens for converging the first light beam or the second light beam introduced from the group of lenses; and a light beam detection element which receives the first light beam or the second light beam converged from the lens and converts the first light beam or the second light beam into an electronic signal.
