摘要： An image forming apparatus including a document-inlet, a multifunction opening, a document-outlet, a first document path and a second document path, is provided. The multifunction opening selectively functions as a document inlet or a document outlet. The first document path, responsive to the document fed in through the document-inlet, directs and drives the document from the document-inlet to the illumination/scan position, and, after the document is scanned, discharges the document to the multifunction opening. The second document path, responsive to the document fed in through the multifunction opening, directs and drives the document from the multifunction opening to the illumination/scan position, and, after the document is scanned, discharges the document to the document outlet. A section of the first document path and a section of the second document path overlaps to each other and defines an overlapping path.

摘要： The present invention provides a sheet-fed scanner which can preview a document. The sheet-fed scanner comprises a housing having an opening for feeding a document to be scanned, a scanning module installed in the housing for scanning the document, a driving mechanism for driving the document forward and backward, first and second sensors installed at a front end and a rear end of the driving mechanism for detecting the document, and a control circuit for controlling operations of the scanner. When the document is fed into the opening and detected by the first sensor, the control circuit uses the driving mechanism to drive the document forward until the document is detected by the second sensor. And when the control circuit receives a preview instruction, the control circuit uses the driving mechanism to drive the document forward and uses the scanning module to perform a preview scan over the document until the document is no longer detected by the first sensor. And then the control circuit will use the driving mechanism to drive the document backward for a normal scan.
