The market can be divided into non-contact landscape detectors (such as Charge Coupled Device (CCD)) scanners, and contact lmage sensors (CIS). Scanner. The non-contact silk-type touch-sensitive image uses a light source to project light onto the document to reflect the content of the document to become an image beam, and then to change the optical path of the image beam through multiple mirror reflections. Finally, the optical signal is converted into an electrical signal by focusing on the non-contact image sensing ϋ. The components of the conventional image sensor scanner, the mirror, the image taking lens, and the non-contact image sensor are usually disposed on a rack. When the non-contact image sensor is used When the scanner scans, the rack moves the above-mentioned items along the file to be scanned, so as to convert the entire contents of the file to be scanned into a sneak mark.

Optical mechanism 20. The optical mechanism 20 includes a chassis 21, a non-contact image sensor 22, a light source 23, three reflecting mirrors 24, a pickup lens 25, and three shock absorbers. Item 26. Wherein: the frame 21 is disposed at a predetermined distance below the glass transparent plate 10, and the frame 21 is driven by a motor (not shown) to move relative to the glass transparent plate 1〇. The non-contact image sensor 22 is fixed in the frame for converting an optical signal into an electrical signal. In this embodiment, the non-contact image sensor 22 is exemplified by a charge coupled device (CCD), which is not limited thereto, and may be a complementary metal oxide semiconductor (c〇mplementary Metal Oxide Semkcmductor, CMOS) or other non-contact image sensor. The light sources 23 are fixed on the frame 21 and located in the frame 21 and the glass transparent plate 10.
