Abstract:
1. An optical reading device of a scanning apparatus, comprising: a housing having a first slot and a second slot in a surface thereof; a first light source beside said first slot for providing a first light when said optical reading device is operated in a flatbed scanning mode; a second light source beside said second slot for providing a second light when said optical reading device is operated in a sheetfed scanning mode; a first mirror disposed under said first slot for reflecting said first light entered via said first slot; a second mirror disposed under said second slot for reflecting said second light entered via said second slot; a movable mirror selected to allow for passing said first light without being obstructed by said movable mirror in said flatbed scanning mode or allow for reflecting said second light coming from said second mirror in said sheetfed scanning mode; a mirror set for successively reflecting said first light coming from said first mirror in said flatbed scanning mode and successively reflecting said second light coming from said movable mirror; a lens set for focusing said first light coming from said mirror set in said flatbed scanning mode and focusing said second light coming from said mirror set in said sheetfed scanning mode; and an optical sensing module for receiving said first light and said second light and converting said first light and said second light into electrical signals, wherein said first light source, said second light source, said first mirror, said second mirror, said movable mirror, said mirror set, said lens set and said optical sensing module are contained inside said housing.
