Integrated scanning device for reflection scanning and transparency scanning

An integrated reflection and transparency scanning device having a side edge and an upper surface, comprising:

• a transparency processing section located inside the scanner close to the side edge, wherein the transparency processing section includes a document feeding port, a plurality of rollers, a first light source and a driving motor, wherein the document feeding port has a long narrow slit in the upper surface of the scanning system, the rollers are evenly distributed from a region close to the document feeding port towards a base of the scanning device, the first light source is positioned between the document feeding port and the side edge for producing a first light beam, and the driving motor is used for driving the rollers in a vertical direction;
• a reflection processing section close to the upper surface of the scanning device, wherein the reflection processing section includes a second light source located inside the scanning device close to the upper surface for producing a second light beam;
• and
• an optical system inside the scanning device, wherein the optical system includes a first carrier, a second carrier, a lens and an optical sensor, wherein the first carrier includes a first reflection mirror, the second carrier includes a second reflection mirror set, the first reflection mirror is located at a cross-point between the first light beam and the second light beam, the second reflection mirror set deflects the first light beam or the second light beam towards the lens, and the lens focuses the first light beam or the second light beam and projects the light beam onto the optical sensor for the production of an image.
