ABSTRACT:
A changeable resolution apparatus and method for scanner includes two rotational disks which have respectively a plurality of lenses of different focuses and a plurality of charge-coupled devices (CCD) of different resolutions located therein. A motor is provided to drive a transmission shaft to rotate in a positive or a reverse direction. Two one-way shaft bearings are engaged with the transmission shaft to drive the rotational disks one-way in opposite directions for changing lens and CCD combination to reach different resolutions. The apparatus is located in the scanner for users to adjust scanner resolution based on scanning requirements to get optimum resolution result.
