ABSTRACT:
A document paper size detection method and apparatus, in a facsimile device, having a plurality of sensor cells forming a charge-coupled device (CCD) sensor module which is repositioned according to a determination by a CPU as to whether the facsimile is to be operated in a book scanning mode or a sheet feeding mode. In the book scanning mode the CCD sensor module is move to a scan starting position and the scanning operation is performed. In the sheet feeding mode the CCD sensor module is moved to a location for detecting an optical sensor reflecting unit, and based upon an optical alignment of one of the plurality of sensor cells with the optical sensor reflecting unit, a size of the sheet of paper to be scanned in the sheet feeding mode is calculated. The CCD sensor module is then moved to a scanning location for scanning the sheet of paper and the sheet of paper is automatically fed past this scanning location.
