US Patent 7170649 Scanning module having an adjustable height

A scanning module having an adjustable height includes a CIS module having two ends along a longitudinal direction each provided with a distance adjusting member. Thus, when the CIS module is scanning the reflective document and the transparency, the distance adjusting member may be adjusted to change the distance between the CIS module and the glass window for the to-be-scanned document to be placed on. Thus, under scanning of the CIS module, both of the reflective document and the transparency may obtain a clear image effect.
