  • Patent number: 9609164
    Abstract: A scanning device includes a visible light source, an infrared light source, a visible light sensor and an infrared light sensor. The visible light source provides visible light to a scan section of an original. The original reflects the visible light to generate reflected light. The infrared light source provides infrared light to the scan section. The infrared light penetrates through the original to generate penetrating light. The visible light sensor receives the reflected light at a first scan position and generates a visible light image signal representative of a visible light image of the scan section. The infrared light sensor receives the penetrating light at a second scan position and generates an infrared light image signal representative of an infrared light image of the scan section. A relative positional relationship between the first and second scan positions is fixed.

    Abstract: A transport mechanism for a peripheral device and an operating method including the same are provided. The transport mechanism includes a tray, at least a transport roller, a detector, a trigger component and a processor. The tray includes an opening extending through the tray. The transport roller is rotatably installed in the opening and protruded from the tray to transport a flexible object to move along a transport path. The detector near the tray has a detecting area. The trigger component is located in the opening and spaced apart from the flexible object on the transport path. The flexible object deviated from the transport path presses the trigger component to enter or leave the detecting area and triggers the detector to transmit an abnormal detecting signal. The processor receives the abnormal detecting signal to stop the transport roller.
