ABSTRACT:
An optical scanner utilizes a simplified driving device for providing stable light path for improving the qualities of images. With the concern of high resolution and simple structure, the invention includes an illuminating carriage, a photoelectric converting device, a pair of lead screws and support, and a driving device. The illuminating carriage is mounted on first lead screw and support for providing light source. The photoelectric converting device disposed below the illuminating carriage is mounted on second lead screw and support. When scanning, the driving device rotates first lead screw and second lead screw to drive the illuminating carriage and the photoelectric converting device in different directions and in synchronism.
