Abstract
The present invention provides a kind of compact-thin contact image sensor, particularly a fingerprint optical input apparatus, which can extract fingerprint image with a strip-type sensor. And it can produce fingerprint image with high definition, and shorten its size with the multibend light pipe. In addition, it has an enough guiding length for forming a strip area distributed uniformly, and the light would project on the strip-type fingerprint pressed on a transparent panel from some angle and reflect to the strip-type sensors by total internal reflection. Lastly, the forest fingerprint image would be extracted by moving the finger.
