摘要： A scanning device includes a transparent platen, a scanning module, a sheet-feeding mechanism, a section and a pressing unit. The scanning module is disposed at a scan position and acquires an image of a document through the transparent platen. The sheet-feeding mechanism transports the document in a transporting direction across the scan position. The section is located downstream of the scan position, and has a low point at a level lower than that of an upper surface of the transparent platen. The pressing unit is disposed opposite the section and limits a distance between the document and the transparent platen.

摘要： A scanning module disposed on one side of a transparent platen of a scanner for scanning a document disposed on the reverse side of the transparent platen is provided. The scanning module comprises a base, a lamp, a holder and an optical sensing component. The lamp for illuminating the document comprises a first section and a second section. The first section extends substantially parallel to a plane of the transparent platen. A first end of the second section is connected to one end of the first section. The shortest distance between a second end of the second section and the transparent platen is greater than that between the first section and the transparent platen. The holder is disposed on the second section for fixing the lamp to the base. The optical sensing component is used for receiving the light reflected by the document and converting that into an image signal.

摘要： A sheet-fed scanning device capable of detecting a document edge includes a scanning module and an automatic document feeder. The scanning module scans a document with a light ray. The automatic document feeder feeds the document across a scanning region on a sheet passageway for the scanning module to scan. In this invention, a section of a guide plate of the sheet passageway located within the scanning region is formed with a concave portion, wherein the document moving across the scanning region is located between the concave portion and the scanning module, such that the intensity of a first brightness of the concave portion sensed by the scanning module is far smaller than the intensity of a second brightness of the document sensed by the scanning module. Thus, it is possible to facilitate the document edge detection and the document skew correction.

摘要： An automatic document feeder includes a front feeding roller set, a rear feeding roller set, a document control roller and a movement-driving mechanism. The document control roller is disposed between the front feeding roller set and the rear feeding roller set and is located above a scan platen with a gap left therebetween. The front feeding roller set transports a document across the scan platen and then to the rear feeding roller set. The document control roller is rotated to assist in transporting the document and to press the document toward the scan platen. The movement-driving mechanism moves the document control roller such that the gap between the document control roller and the scan platen is adjusted. Thus, a scanning module below the scan platen can scan an image of the document.

摘要： A scanning device includes a first chassis, a second chassis and a calibration mechanism. The first chassis is for scanning one side of a document. The second chassis is for scanning the other side of the document. The second chassis is movably disposed opposite the first chassis. The calibration mechanism is for calibrating the color depth of the scan image. The calibration mechanism includes a calibration sheet and an elastic member. One end of the elastic member is fixed in the scanning device. The second chassis exerts a force on the calibration sheet to generate a relative movement between the calibration sheet and the first chassis. When the second chassis ceases exerting the force, the elastic member releases a resilient force for moving the calibration sheet to a starting position. The first chassis performs dynamic calibration by the relative movement between the first chassis and the calibration sheet.
