Patent number: 7751100Abstract: 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.Type: GrantFiled: August 21, 2006Date of Patent: July 6, 2010Inventor: Yu-Shan Chang

Patent number: 7450276Abstract: A scanning apparatus includes a housing with a scan flatbed. A loading glass is installed at the scan flatbed of the housing for loading a to-be-scanned document. A photoelectric sensing device senses the light corresponding to the to-be-scanned document to generate electric signals. The electric signals are transmitted through a flat cable to a motherboard. The flat cable is designed to include a line peak so that the surface friction between the flat cable and the loading glass can be reduced to line friction. The flat cable can also be shifted near the sidewall of the housing and is inclined to the center of the housing so that the friction traces remained on the loading glass is outside the scan flatbed. Thus, the abrasion on the loading glass can be reduced and the quality of the scanning images can be improved.Type: GrantFiled: August 16, 2006Date of Patent: November 11, 2008Inventor: Yu-Shan Chang
