ABSTRACT:
A document scanner method and apparatus is provided which allows for the detection of the presence and size of a document to be scanned. The scanner would also determine whether the document being scanned is crooked. The document scanner includes an automatic document feeder, which feeds the document into the scanner. As the document is being fed into the scanner by the automatic document feeder, an array of CCDs detects the size of the document using a code strip. 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 as to the area to be scanned.
