  • Publication number: 20030085507
    Abstract: An automatic paper feeder with an integrated paper presser and stopper is disclosed. The integrated paper presser and stopper includes a fixing section, a paper pressing section downward extended from the fixing section at an inclined angle toward a paper-out end of the paper tray, a first bent section formed at a lower end of the paper pressing section to define a first gap, a paper stopping section downward extended from the first bent section at an inclined angle toward the paper-out end of the paper tray, and a second bent section formed at a lower end of the paper stopping section to define a second gap which is smaller than the first gap.

  • Publication number: 20030085509
    Abstract: An automatic paper feeder for an image-scanning device with a pressure-adjustable mechanism for adjusting the paper feeding roller of the automatic paper feeder is disclosed. A pressure from paper sheets stacked on a paper tray of the automatic paper feeder is detected by a paper tray pressure detecting mechanism and transferred to a roller pressure adjusting mechanism to change a pressure between the paper feeding roller and a paper separating plate and adjust a feeding angle of the movable paper tray.

  • Publication number: 20020181031
    Abstract: An automatic document feeder for an image forming apparatus, such as a scanner, is provided. The automatic document feeder comprises a document-loading means, a document-receiving means, a sheet path, a sheet-transporting mechanism, a scan window, a first sensor means and a second sensor means. The first sensor means is disposed at the entrance of the sheet path and the second sensor means is disposed at a predetermined position along the sheet path. The second sensor means includes a sensor device and a rotatable shaft attached thereto. When the sheet-transporting mechanism transports at least one sheet along the sheet path through the second sensor means, the rotatable shaft is rotated at a predetermined angle.
