Abstract: A filtering method and mechanism for scanners includes a regular visible light source and an infrared light source that are both turned on under a scanner normally on state during scanning operation. A transmission mechanism is provided for reciprocally placing a visible light filter plate and an infrared light filter plate in the scanner light path to filter light emitting from the regular visible light and infrared light source. Changing and switching between regular and infrared light scanning may be done quickly without warm up delay of the light source. More versatile and powerful function thus may be built in the scanner.

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.
