Description of the invention α) [Technical field to which the invention belongs] The present invention is an optical element for collecting light, which is applied to a flat image input device, and in particular, it can improve the light emitted by a 5 light source in a flat image input device. Utilization of optical components. [Previous technology] In addition to pictures, videos, multimedia, and computer presentations, there is also a need to use digital information in daily business paperwork. Although the paperless office has not yet been realized, scanning operations have been used in business. The use of electronic information on the paper to reduce the use of paper, the role that you want. , Dong — Zhizhi has always been a very popular input device, because it is very easy to operate. 'Just open the lid of the scanner and place the original on the glass. After you put the lid on it, you only need to operate it. Software to control the scanning module to perform scanning operations. The principle of the scanner is to use a mechanical or electronic scanning module to read the image points on the original paper and convert them into digital form. Since the f source is used to project on the original paper, the image points are scanned. The reflection brightness conversion is known, so it is also called photoelectric conversion. During the process of reading the image signal of the original paper surface by the image sensor, the light emitted by the illumination light source is projected onto the original paper surface, and the reflected light on the original paper surface is imaged by the lens To the sensing element, it is photoelectrically converted into an output voltage proportional to the image density. As shown in "Figure 1", because the design of the lighting source used by the scanning module in the scanner 'is often only the light emitted from its half will be used, so know, bright and light from the source to The part of the scanned file is also
