Description of the invention: [Technical field of the invention] The present invention relates to a scanning module having a sweeping full, main, cut, and looking-to-sight, moon-cleaning function, in particular, a cleaning scan window Scanning module. [Prior Art] The life of the scanner is usually very long. However, when the scanner is exposed to the atmosphere for a long period of time, the surface of the scanning window may be slightly contaminated, and the inner surface of the scanning window may be affected by a humid environment to generate particles such as mold. The surface exposed to the outside can be easily cleaned, and the surface of the scanning window can be used by the general user without the ability to perform the cleaning operation of the inner surface of the scanning window. And performing this action ^ requires considerable time and labor. When the surface of the scanning window has particles remaining on it, the image obtained by the scanning will be deteriorated, which is a situation that the user is unwilling to encounter. Group 2, how to provide a scanning module with scanning window cleaning function, which is the problem to be solved in this case. SUMMARY OF THE INVENTION One object of the present invention is to provide a scanning window cleaning function, which can perform a cleaning scan window automatically or not. The present invention provides a scanning window cleaning function that moves below a scanning window to capture a bit.

The scanning module comprises a casing, an image sensor and a scanning window cleaning module. The image sensor is mounted in the housing for sensing the optical signal from the original to obtain an image signal corresponding to the original image. The scanning window cleaning mold is assembled on the housing to clean the scanning window facing the lower surface of one of the scanning modules. The above described objects, features, and advantages of the present invention will become more apparent and understood. [Embodiment] FIG. 1 is a view showing a scanning module with a scanning window cleaning function applied to a scanning device according to a first embodiment of the present invention. Fig. 2 shows a schematic view of a scanning module having a scanning window cleaning function according to a first embodiment of the present invention. The scanning module of the invention is also suitable for image capturing devices such as photocopiers and multi-function machines. As shown in FIG. 2 and 2, the scanning module 10 with the scanning window cleaning function of the embodiment is generally installed in a flatbed scanner 30 and is disposed along a guide bar 32 in the flatbed scanner. Moving below the scanning window 20 to capture an original image of one of the originals D located on the scanning window 2q. The scanning module ίο mainly includes a housing u, an image sensor 12 and a scanning window cleaning module 13. The image sensor 12 is mounted in the housing i to sense an optical signal from the original D to obtain an image signal corresponding to one of the original images. The scanning window cleaning module 13 is mounted on the housing 11 for cleaning the scanning window 2 to face one of the lower surface 20A of the scanning module. In this embodiment, the image sensor 12 is a charge-coupled 6 200814734 component (CCD) image sensor. Therefore, the scan mode k Η) further includes a light source 15 , at least one mirror 16 and a lure Mirror 17. It is to be noted that when the original D is a penetrating document, the light 9/original 15 is a member that can be omitted. In this case, another light source (not shown) is located above the scanning window 20. There are two applications for the scanning window cleaning module 13, the first one is to clean the scanning window when the document is scanned, and the second is to clean the scanning window when the file is not scanned. In the first case, the scan is performed after the cleaning is performed. Therefore, the scan window is cleaned, and 13 must be positioned before the scan line. In the second case, the sweep: window: the clean module 13 can be located in front of or behind the scan line. In the case of the 'scanning device' # can be designed to scan the device: booting to perform the scanning window cleaning work. Or, when the scanner is fixed for a fixed period of time (such as 1 day), the scan window =, , work is automatically executed. Alternatively, the user can control the ▼ window cleaning module 13 to perform the cleaning work through a button or a software. In the present embodiment, the scanning window cleaning module 13 includes a doctor blade or a movably contact with the lower surface 2〇α of the scanning window 2 for 'making a private Φ BB B', a lower surface 20 A Particles. The material of the scraper or brush is the most 产生b to generate static electricity after rubbing against the broken glass, thereby enhancing the effect of the particulate absorption. In order to improve the 隹 止 尺 堤 一步 一步 step by step to enhance the cleaning effect, scanning window cleaning module - blowing unit -, - suction single TM two cleaning sheet σ early 13D.
