The present invention is to provide an image scanner, for scanning a reflection document or a transmission document. The image scanner comprises a shell, a document window glass, a transmission document carrier, and an optical chassis. The shell has a groove on its upper surface. The document window glass is capable of connecting with the groove, for scanning the reflection document. The transmission document carrier is capable of connecting with the groove, for scanning the transmission document. The optical chassis is provided at a proper location, for retrieving the images of the reflection document and the transmission document and converting them to an electronic signal. Wherein, by placing the document window glass or transmission document carrier into the groove, the image scanner is capable of scanning the reflection document or transmission document, respectively.
1. A scanner, comprising:
a shell, having an upper and lower surface, wherein a groove is formed on the upper surface, said groove having at least one hole formed therein;
a fixing assembly disposed in the at least one hole, wherein the fixing assembly is adapted to fix a substrate to the groove;
a first light source to provide light to a document disposed on the substrate; and
an optical module to receive light reflected from the document disposed on the substrate.
2. The scanner of claim 1 , wherein the substrate comprises one of a document window glass and a transmission document carrier.
3. The scanner of claim 1 , wherein the fixing assembly comprises an elastic element coupled to a blocking bead that is moveable within the at least one hole.
4. The scanner of claim 2 , wherein the elastic element comprises a spring.
5. The scanner of claim 1 , wherein the fixing assembly comprises a spring.
6. A method, comprising:
forming an optical scanner shell having an upper and lower surface;
forming a groove on the upper surface of the shell;
forming a hole in the groove; and
disposing a fixing assembly in the hole, wherein the fixing assembly is adapted to fix a substrate to the groove.
7. The method of claim 6 , wherein the substrate comprises one of a document window glass and a transmission document carrier.
8. The method of claim 7 , and further comprising:
disposing a light source substantially in the shell, wherein the light source is adapted to provide light incident on the one of a document window glass and a transmission document carrier; and
disposing an optical module substantially in the shell, wherein the optical module is adapted to receive light reflected from a document disposed on the one of a document window glass and a transmission document carrier.
9. A scanner comprising:
a scanner body having a groove to support a substrate for document scanning, the groove having at least one hole formed therein; and
a fixing assembly disposed in the hole and adapted to fix the substrate to the groove in the scanner body.
10. The scanner of claim 9 , wherein the fixing assembly comprises an elastic element coupled to a blocking bead.
11. The scanner of claim 10 , wherein said elastic element comprises a spring.
12. A scanner, comprising:
a body having a groove with a hole formed thereon; and
a fixing assembly disposed in the hole to fix a substrate to the groove, said fixing assembly adapted to enable selective scanning of transparent type documents or reflection type documents.
13. The scanner of claim 12 , wherein the fixing assembly comprises an elastic element coupled to a blocking bead.
14. The scanner of claim 13 , wherein the elastic element comprises a spring.
15. The scanner of claim 12 , wherein the fixing assembly comprises a spring.
16. The scanner of claim 12 , further comprising:
a first light source disposed on the body, and adapted to provide light incident to a document disposed on the substrate; and
an optical module disposed on the body, and adapted to receive light reflected from the document disposed on the substrate.
