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.
