Abstract: A light source mechanism for an imaging apparatus comprises at least a point light source and a light shield. The point light source located at one end of the light shield is used for providing illumination to the imaging apparatus during a scanning process. The light shield is a hollow pipe structure and further includes a long slot lying along an axial longitudinal direction thereof for allowing lights to leave the light shield. An inner surface of the light shield is made as a diffusion surface for evenly diffusing lights inside the light shield, by which a homogeneous line light source for the scanning process is formed at the long slot of the light shield.

Abstract: A method of detecting the alignment of a document in an automatic document feeder including an optical scanner that has an automatic document feeder and a document. The automatic document feeder has a colored pattern layer corresponding to a scanning window of the optical scanner. The document has at least one side edge. When the document is being fed into the automatic document feeder, the side edge is just positioned between the scanning window and the colored pattern layer. When the automatic document feeder is switched on to feed in the document, a first image retrieval is made from the document placed on the scanning window. After the document is fed in by an appropriate length, a second image retrieval is made from the document placed on the scanning window. A slant value is calculated.
