Scanning apparatus
View Patent ↗A scanning apparatus includes a housing with a flatbed. A loading glass is installed at the scan flatbed for loading a to-be-scanned document. A photoelectric sensing device is disposed in the housing for sensing the light signals corresponding to the to-be-scanned document to generate electric signals. The electric signals are transmitted through a flat cable to a motherboard. When the photoelectric sensing device shifts and the flat cable touches the bottom of the housing, the first adsorptive slice of the flat cable and the second adsorptive slice on the bottom of the housing adsorb each other. Therefore, the rubbing between the flat cable and the loading glass can be avoided and the quality of the scanning images can be improved.
1. A scanning apparatus having a housing with a scan flatbed, a loading glass being installed at the scan flatbed for loading a to-be-scanned document, the scanning apparatus comprising:
a photoelectric sensing device, disposed in the housing, for sensing a light signal corresponding to the to-be-scanned document to generate an electric signal;
a circuit board, disposed in the housing, for receiving the electric signal; and
a flat cable comprising a first adsorptive slice, for connecting the photoelectric sensing device to the circuit board and transmitting the electric signal; and
a second adsorptive slice being stuck on a bottom of the housing;
wherein a touching area between the flat cable and the bottom of the housing changes as the photoelectric sensing device shifts; and the first absorptive slice and the second absorptive slice corresponding to the touching area adsorb each other.
2. The scanning apparatus according to claim 1 , wherein the photoelectric sensing device comprises a contact image sensor (CIS).
3. The scanning apparatus according to claim 1 , wherein the photoelectric sensing device comprises a charge coupled device (CCD).
4. The scanning apparatus according to claim 1 , wherein the to-be-scanned document is a reflective document.
5. The scanning apparatus according to claim 1 , wherein the to-be-scanned document is a transmissive document.
6. The scanning apparatus according to claim 1 , wherein the circuit board is a motherboard.
7. The scanning apparatus according to claim 1 , wherein materials of the first and the second adsorptive slices are magic felts.
8. The scanning apparatus according to claim 7 , wherein the first and the second adsorptive slices adhere to each other section by section.
9. The scanning apparatus according to claim 1 , wherein materials of the first and the second adsorptive slices are soft magnetic slices with slight magnetism.
10. A flat cable for being installed in a housing of a scanning apparatus, the housing having a bottom, the flat cable comprising:
a cable; and
a first adsorptive slice, being located beneath the cable and facing the bottom of the housing;
wherein a second adsorptive slice is stuck on the bottom of the housing, and the first absorptive slice and the second absorptive slice corresponding to a touching area between the flat cable and the bottom of the housing adsorb each other.
11. The scanning apparatus according to claim 10 , wherein materials of the first and the second adsorptive slices are magic felts.
12. The scanning apparatus according to claim 11 , wherein the first and the second adsorptive materials adhere to each other section by section.
13. The scanning apparatus according to claim 10 , wherein materials of the first and the second adsorptive slices are soft magnetic slices with slight magnetism.
