Technical Field

The utility model relates to the technical field of shading structures, in particular to an adjustable shading structure of a file scanner.

Background

The scanner is an image signal input device, and the working principle thereof is as follows: optically scanning an original is converted into a digital image form. The scanning step of the scanner is that the original to be scanned is spread on the surface of the scanner, the scanner optical scanning driving program is started, the optical image is scanned and obtained, then the optical image is transmitted into the photoelectric converter to be changed into the analog electric signal which can be accepted by the computer, the analog electric signal is converted into the digital electric signal, and finally the digital electric signal is transmitted into the computer through the computer interface.

The quality of the optical image directly influences the quality of the scanning piece in the scanning process, if other external light sources intervene in the scanning process, the optical image quality is influenced by misleading light signals, especially the external light sources possibly cause uneven illumination due to the reasons of light irradiation angles and the like, so that the problems of shadow or unclear scanning piece and the like appear, and in order to ensure the quality of the optical image, the external light sources need to be shielded in the scanning process, and the intervention of the external light sources is avoided as much as possible.
