摘要
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.
