Abstract
A contact image sensor (CIS) for scanning a document is disclosed. The CIS includes a housing having an opening, a first slide and a second slide, a light guide installed on the housing through the opening and the first slide for scanning the document and generating a reflective image, a rod lens installed on the housing through the opening and the second slide for receiving the reflective image and generating a focused image, a PCB installed on the housing and having a sensing array for transforming the focused image into an image signal, and a spring cover fixed on the opening for fixing the light guide and the rod lens in the housing to form the CIS.
