Problems solved by technology

Generally speaking, it is easier for stray light to enter the casing 110 through the middle position of the light-transmitting slit 112, so that the color of the document 180 sensed by the optical sensing device 150 will be different due to the position of the document 180 placed on the glass plate 190. , resulting in reduced image quality and increased noise

Abstract

The scanning module suitable for scanning file includes one casing, one light source, at least one reflector, one lens and one optical sensing device. The casing has one transmissive slot of different width in different lengthwise positions. When the light source irradiates the file, one image is formed and is passed through the transmissive slot and is projected onto the reflector and then thereflected image can be passed through the lens and is projected onto the optical sensing device.

Description

technical field [0001] The present invention relates to a scanning module with light-transmitting slits, and in particular to a scanning module with double-horn-shaped light-transmitting slits. Background technique [0002] With the great improvement of computer performance and the high development of Internet and multimedia technology, in addition to using digital cameras to directly capture image patterns, other image input operations related to documents or pictures need to be captured by optical scanners Analog images of characters or patterns are converted into digital signals for output, which is helpful for users to display, identify, edit, store and output image files on computers or other electronic products. [0003] In the scanning system, one of the factors that determine the quality of scanning is whether the system can accurately transmit the image of the object to be scanned to the optical sensing device, so that the image sensing device can play the best role...
