A document scanner method and apparatus is provided which allows for the detection of the presence and size of a document 11 to be scanned. The scanner 50 would also determine whether the document 11 being scanned is crooked. The document scanner 50 includes an automatic document feeder 23, which feeds the document 11 into the scanner 50. As the document 11 is being fed into the scanner 50 by the automatic document feeder 23, an array of CCDs 21 detects the size of the document 11 using a code strip 27. The CCD signal of the detected document size is then converted to an electronic signal which is sent to application software. The application software then instructs the scanner 50 as to the area to be scanned. <IMAGE> |
