Abstract
A contact image sensing module with movement detecting function has a main circuit substrate, a linear sensor array, at least a movement detecting element, a light source, a light-guiding device, and a detecting surface. The main substrate is a flex-rigid composite substrate having a structure making the linear sensor array have a tilted angle. The linear sensor array has at least a comparison sensor corresponding to at least a movement detecting element. The movement detecting element and the comparison sensor, respectively, draw a section of reference image data and a section of comparison image data from a sensed object. After processing a shift-times deciding equation and a speed deciding equation, the moving speed of the sensed object relating to the movement detecting element and the comparison sensor can be obtained. The structure of the light-guiding device makes the light from the light source to the sensed object more uniform.
