Abstract
The present invention provides a scanner with an object distance adjusting device that allows effective scanning of documents placed at varying heights over its transparent platform. The scanner comprises a movable scanning module with an optical sensing device for converting light into image signals, a lens set for focusing light onto the optical sensing device, and an object distance adjusting device for adjusting the object distance from the lens set to the document. The object adjusting device allows accurate object distances regardless of whether a transmitted document or a reflective document is scanned leading to exact resolution and high scanning quality.
