CCD rotary-alignment device for optical scanner

Year	Description
1998	Invention patented by Jenn Tsair Tsai on June 18th, 1998. 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; a positioning element mounted on the holder for adapting a CCD to be slightly rotated in a plane around a pivot point fixed on the holder and aligned with the focused image. The positioning element is furnished with a matching hole for precisely carrying a bottom portion of the CCD. The positioning element mounting to the holder needs only one dimensional adjustment which is easier and more effective.
