The light source device 'can achieve the same image quality requirements; among which, the original = text = _cxmment Sheet) is white' is used as the light source reflection interface. So that consumers do not need to buy a light plate device, Ke Tong can avoid penetrating / reflecting documents or graphic manuscripts. Annoyance # Refer to the second diagram of its towel. Figure 2A The schematic view of the light source path when scanning through the manuscript (transparent film). The reference number 50 is the original Document Sheet 50 of the scanner. The document sheet 50 may be a thin sheet of plastic PVC material. Obviously, when the scanner scans the penetrating document (that is, a transparent film) at 60, the light source 70 irradiates the penetrating document 60 and refracts it once. After entering the penetrating document 60, it will be reflected when it encounters the document board 5G ', and then it will reflect again when the penetrating = 60. So there will be secondary refraction and secondary reflection of light energy loss to be compensated. The method proposed by the present invention is used to further compensate the luminance (brightness) of the light energy f loss of the through-paper. On the other hand, FIG. 3B is a schematic diagram of the light source path when the scanner scans and reflects. The difference from Figure 3A lies in the description of the scanned manuscript, so that a reflected manuscript has less light energy loss. Compared with the scanning through the manuscript, the compensation of brightness (brightness) is not needed. This means that the present invention is able to take into account both functions of penetrating manuscript scanning and reflection manuscript scanning. For the method of compensating penetrating manuscript scanning brightness described in the present invention to achieve the purpose of one machine and two uses, it is to adopt two implementation Method: 1.Enhance the brightness of the light source: When the document or graphic draft is scanned through the manuscript, the voltage output in the driver circuit (Driver) is set to provide the lamp power according to the high-level signal, so as to provide the individual required light source brightness requirements . 2 · When changing the exposure of the charge-coupling element The paper size applies the Chinese National Standard (CNS) A4 specification (210 house: 297 mm) (Please read the precautions on the back before filling this page)

Employees' cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs print room: When scanning through documents or graphics, the exposure time set in the driver circuit is long and short to compensate for the higher light source brightness required for penetrating documents.疋 With the principle and method applied by this technology, consumers can save the cost of purchasing an oscillating plate device, and can achieve the function of dual-use (transmission / reflection). For this reason, Figure 4 is a schematic diagram of the structure of the implementation of the method of the present invention without the need to purchase an additional calendering device, which means that in the case of using a single light source device, both transmission and reflection can be achieved. The scanning method used. It includes an optical module (Chassis) 100 underneath, and a light source 120 is provided to illuminate the document to be scanned. The irradiated light will first be refracted to a scan file 108 through a Glass Windows 110. If the scan file 108 is a reflective draft, the light will be reflected; if the scan document is a penetrating draft (transparent film), the light will be Will continue to shine on a document board (D〇cument

Sheet) 106. Generally speaking, the document board 106 is a white plastic (pVc) material, which serves as an interface for light source reflection. After that, the light is reflected by the document plate 106, refracted into the selection file 108, and finally the image signal is read out. So in general, the light energy loss caused by two refractions and one reflection during penetrating scanning is more necessary to compensate. In addition, as shown in Fig. 4, a foam 1Q4 is placed on the top of the document board 106, and then it is connected to the Document Cover 102. In this way, only the document board 106 (which is made of white plastic (PVC) material) is used as the reflection interface of the light source, and no additional calendering device is required.
