ABSTRACT:
A device for holding a charge couple device (CCD) in an optical scanner where optical alignment of the CCD to the position of scanned image of document can be easily made. The device includes a holder for holding a lens and providing a focused image taken from the scanned document; and a positioning element mounted on the holder for adapting a CCD to be slightly moved in a line along a longitudinal direction of the CCD and aligned with the focused image. The positioning element is furnished with a matching hole for carrying a bottom portion of the CCD. The positioning element mounted to the holder only needs one-dimensional adjustment in shifting which is easier and more effective.
