Abstract: A multiple-resolution scanning device introduces an image information obtained by scanning a document into a light folding device and the image information is reflected in the light folding device. The image information comes out from the light folding device and received and reflected by a final reflection mirror unit, and passes through a lens unit and then focused on an optical sensor. By adjusting the light folding device or the final reflection mirror unit, or by adjusting the light source and the light folding device to change the position or angle thereof to achieve the purpose of changing the path of light of the image information and obtain the scanned results having different resolutions.

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 light sensing apparatus includes a sheet passage, a first sensing assembly and a first background sheet. The sheet passage has a scan window. The first sensing assembly disposed on a first side of the scan window outputs first scan light to the scan window. The first background sheet disposed on a second side of the scan window has a first reflective surface reflecting the first scan light, passing through the scan window, back to the first sensing assembly through the scan window. The first reflective surface of the first background sheet and the scan window are disposed in a non-parallel manner. Therefore, a light sensing method is also provided to achieve the effects of brightness calibration and boundary detection of the first sensing assembly.

Abstract: The present invention discloses a stacking tray device to be used for a business machine. The stacking tray device comprises a tray, a guide plate and a stopper, wherein paper is placed on the tray, the guide plate moves relative to the tray and restricts the size of the paper, and the stopper sets the position where the guide plate stops when the guide plate is pushed from the center towards the outside. When the stopper is in a lock position, the guide plate stops at a first position corresponding to a first standard paper size; when the stopper is in an unlock position, the guide plate stops at a second position corresponding to an oversized paper size.

Abstract: A multi-purpose scanner comprises a first body, a second body and a scanning module. The second body is disposed on the first body. A first passageway and a second passageway, which are for accommodating a first portion and a second portion of an angled document, and are disposed on a first plane and a second plane, respectively, are formed between the first body and the second body. An included angle is formed between the first plane and the second plane. The scanning module, disposed in the first body and/or the second body, performs an image scan operation on the first portion of the angled document in the first passageway to obtain an image signal.
