Abstract
A device for detecting a placement position of a document includes at least two sensors mounted on a document feeding device. Each of the sensors is in parallel with the tangential direction of the leading edge of a document feeding roller, and may be moved by the document feeding device to adjust the placing document width. Thus, the document has to trigger all of the sensors so as to drive the document feeding roller, thereby ensuring that the document may be placed in the document feeding device without tilting, and may have a correct document feeding angle
