ABSTRACT:
An adapter for scanning transparent images using a reflective scanner. The adapter receives light from a lamp inside the scanner and redirects the light through the transparent image and back into the scanner. The scanner has an offset between an illumination line and a scan line. An angle of the adapter relative to the surface of a platen on the scanner is dependent on the distance between the illumination line and the scan line. At least one angle adjuster is provided on the adapter to enable the adapter to be used on scanners having different offsets. In addition, the adapter is made wider than the transparent image to be scanned, so that when the scan line is at a leading or trailing edge of the transparent image, the adapter still captures light from the lamp within the scanner.
