Abstract: An optical scanning module with linear CMOS image sensor (linear CMOSM) applied to scanners or multi-function printers is disclosed. The optical scanning module includes a light source for emitting light, a reflection mirror group, a focus lens group, and a linear CMOS image sensor having at least one linear CMOS image sensor unit and one A/D analog-digital converter. The light source can be a cold cathode fluorescent lamp (CCFL), a Xenon lamp or linear LED. Light emitted from the light source projects onto an object being scanned. Then the light reflected by the object being scanned becomes scanning light, passing through the reflection mirror group and the focus lens group and being focused on the linear CMOS image sensor for being converted into electrical signal. By A/D conversion of the linear CMOS image sensor unit in the linear CMOS image sensor, signal is sent out in USB or LVDS format so as to achieve high scanning speed, low distortion, large depth of focus and convenient transmission.
