Abstract: An apparatus for detecting front edge of a document and determining home position of an image scanning module has a detecting light source near an outlet end of a document feeding track and aligned with an image reader of the image scanning module. The detecting light source emits a detecting light to be received by the image reader. By detecting whether the detecting light is received by the image reader, the front edge of the document can be detected to activate the image scanning module. And it can also determine whether or not the image scanning module has arrived on a home position.

Abstract: A paper feed tray with the image scanning function of a printer includes a set of paper feed rollers, a set of paper exit rollers, and an optical scanning module. The optical scanning module is located between the set of paper feed rollers and the set of paper exit rollers, wherein the paper feed rollers grab documents waiting for being scanned and transfer the documents through the image scanning module. Each of the documents is scanned by the image scanning module and then transferred out of the printer by the paper exit rollers. Hence the printer with the paper feed tray may serve as an image scanning apparatus.

Abstract translation: 具有打印机的图像扫描功能的送纸托盘包括一组送纸辊，一组出纸辊和光学扫描模块。 光学扫描模块位于一组给纸辊和一组出纸辊之间，其中送纸辊抓取等待被扫描的文件并通过图像扫描模块传送文件。 每个文件由图像扫描模块扫描，然后由出纸辊从打印机传出。 因此，具有进纸盘的打印机可以用作图像扫描装置。
