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.

Abstract: A sheet-feeding apparatus includes a passage, a sheet-feeding roller disposed at an entrance of the passage, and a paper pressing mechanism including a paper pressing device and a driving mechanism. The driving mechanism drives the paper pressing device to move towards and away from the sheet-feeding roller. The driving mechanism includes a power source, a rotating shaft connected to the power source, and an arm attached to the rotating shaft. As the rotating shaft rotates in a first direction, the arm actuates the paper pressing device to move away from the sheet-feeding roller. As the rotating shaft rotates in a second direction, the arm releases the paper pressing device, so the paper pressing device moves towards the sheet-feeding roller and presses a paper sheet upon the sheet-feeding roller.

Abstract: A scanner includes an image capturing module, a drive roller assembly, an idle roller assembly, and a guiding structure. The image capturing module is for capturing an image of an object. The drive roller assembly is for driving the object to move along a feeding direction. The idle roller assembly is for preventing a moving direction of the object away from the feeding direction by resiliently pressing the object. A feeding passage is formed between the drive roller assembly and the idle roller assembly. The guiding structure is disposed in front of the feeding passage and for guiding a normal direction of a leading edge of the object to be oblique relative to the feeding direction at an oblique angle. Therefore, the present invention can effectively reduce variation of a resistance force acting on the object as the object moves in the feeding path, which prevents image distortion.
