  • Patent number: 8282096
    Abstract: An automatic document feeder includes a transfer channel, a pick-up module and a thickness detecting module. The thickness detecting module includes a detecting member, a transmission member and an optical displacement sensing member. By the pick-up module, a sheet article is fed into the transfer channel. When the sheet article is transported across the detecting member, the sheet article is sustained against the detecting member, so that the detecting member is moved. The transmission member is connected to the detecting member. As the detecting member is moved, the transmission member generates a displacement amount. The optical displacement sensing member is used for detecting a displacement amount of the transmission member, thereby acquiring the thickness of the sheet article.

  • Publication number: 20120055542
    Abstract: A structure of photovoltaic cell for improving conversion efficiency has been disclosed, including a first bandgap layer, a second bandgap layer, a third bandgap layer, a back electrode and a finger electrode, wherein the first bandgap layer is a wafer while the second bandgap layer is a semiconductor film with a thickness of 1˜100 ? and a greater bandgap than one of the first bandgap layer, and the third bandgap layer comprises wide bandgap materials and a greater bandgap than one of the second bandgap layer. Thereby, the lattice mismatch of heterostructures between the first bandgap layer and the third bandgap layer may be solved by the second bandgap layer. Also, the carrier recombination within devices may be decreased and the output photocurrent may thus be enhanced to improve energy conversion efficiency.

  • Publication number: 20110156337
    Abstract: An automatic document feeder includes a sheet input tray, a transfer channel, a sheet pick-up module, a retard roller, a thickness detecting module and a controlling unit. When the sheet pick-up module is driven, the documents placed on the sheet input tray are fed into the transfer channel. The thickness detecting module is used for detecting a thickness of the documents. The controlling unit is used for judging whether a multiple-feeding event occurs. In a case that the multiple-feeding event occurs, the sheet pick-up module is reversely rotated such that the documents are returned to the sheet input tray. When the sheet pick-up module is reversely rotated, the retard roller provides a lower frictional force, so that the documents are allowed to be returned to the sheet input tray.
