Abstract: A sheet separation mechanism comprises a separation roller set and a reverse roller set rotating in the same rotation direction. The reverse roller set presses sheets onto the separation roller set to stop one or multiple ones of the sheets close to the reverse roller set from passing through a nip between the separation and reverse roller sets, and allow the sheet directly contacting the separation roller set to pass through the nip. The reverse roller set comprises a shaft, and two reverse rollers and an annular member all mounted on the shaft, which rotates the reverse rollers. The annular member, disposed between the two reverse rollers, is rotatable relatively to the shaft and movable relatively to the shaft in a radial direction of the shaft. The annular member and the reverse rollers commonly press the sheets. A sheet-fed scanning apparatus using the sheet separation mechanism is also provided.

Abstract: A sheet storage device includes a sheet tray, two guide plates and a width adjusting mechanism. The sheet tray supports a sheet. The two guide plates, disposed on the sheet tray, guides transportation of the sheet placed on the sheet tray. The width adjusting mechanism, disposed on the sheet tray and connected to the two guide plates, adjusts a distance between the two guide plates. The width adjusting mechanism includes a pinion, a resilient member, a toothed portion and two connectors. The pinion is rotatably disposed. The resilient member is disposed coaxially with and rotated with the pinion. The toothed portion is disposed around the resilient member and in contact with the resilient member. The toothed portion provides a resisting force upon rotation of the pinion. Each connector connects the pinion to one of the guide plates.

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: In a sheet feeder, an input passage has input and output ends and an input location. A first feeder module includes: a first input roller disposed on the input end; a first output roller disposed on the output end; and a first sensing device being disposed near the first input roller and generating a first signal transmitted to a processor upon sensing presence of a first medium. A second feeder module includes: a second input roller disposed on the input end; a second output roller disposed on the output end; and a second sensing device being disposed at the input location and generating a second signal transmitted to the processor upon sensing presence of a second medium. An image acquiring device acquires an image of the first or second medium. The processor controls enabled and disabled states of the first and second feeder modules. A control method of the processor is also provided.
