摘要：
A full contact image sensor device comprising sensor elements adapted to macroscopically touch a document to receive reflected light from the document and to generate electric signals in response thereto, wherein a receiving surface of each sensor element has an uneven contour and the device wherein each sensor element corresponding to a pixel comprises a plurality of sensor element blocks is proposed. The devices are easily manufactured and have excellent MTF and sensitivity.
