Background of the Invention: Please refer to FIG. 1, which is a typical platform-type optical scanning device 1 (Opticai Scanner) embodiment currently available on the market. It is mainly provided with a document window glass (Document Window Glass) on the upper surface of the housing 1 of the scanner 1 to hold a document to be scanned (not shown), and an optical engine 14 is driven by a driving device 13 (Optical Chassis) A linear movement is performed in the hollow housing u along the direction of the guide rod 15 to perform the image scanning work of the original on the glass 12. Refer to FIG. 1 for a cross-sectional view of the optical engine 14 of the conventional optical concealer 1 shown in FIG. The optical engine 14 includes a hollow housing 14 and a light source 142 positioned at an appropriate position on the upper side of the housing 141, a plurality of reflective lenses 143, a lens set 144 (Lens Set), and a charge-coupled element 145 ( CCD). The light emitted by the light source 142 is directed toward the original document (not shown) on the glass 12. After the reflected light enters the housing 141 of the optical engine 14, it is reflected by a plurality of reflective lenses 143 to increase the optical path distance ( (Optical Length) to an appropriate length, after focusing by the lens group 144, it looks like a charge-coupled element 145 and rotates the scanned image data to the next page (if the description page of the invention is not enough, please note and store it ), Gou 6 invention description, continued electronic signals. As shown in Figures 1 and 2, the conventional optical engine 14 has a reflective lens 143 formed by silver plating on a glass sheet, which needs to be fixed to the shell by a reed 146, a clamp mechanism or a lion lock_square wire. At a predetermined position inside the body i4i. Not only the positioning of additional reeds, 146 fixture mechanisms, etc. will directly increase the number of parts and production costs, the large number of parts occupying space will make it impossible to further reduce the size of the optical engine, and increase the assembly man-hours and labor costs. In addition, as long as the amount of silk material is large, it is inevitable that there will be a situation in which the looseness of the loose parts of the part causes the positioning shift of the mirror 4 143 to cause a deterioration in the quality of the scan image. In addition, the practice of using the reed 夹具 as a clamping mechanism to make p ## 143, in the long-term use causes the elastic fatigue of the reed 146 to reduce the clamping force, or the machine suffers from shock due to operation. The mirror > {143 may be loose or the position may be shifted, which may cause the image quality to be reduced, and needs to be improved. Summary of the Invention: The light engine and its manufacturing process, which are mainly judged by the current state of the sun, can reduce the number of parts and reduce the time and cost of assembly and manufacturing, and reduce the optical fresh volume. Taste-reflecting elements are loose or misaligned.

Not only does it not have to worry that the conventional positioning mechanisms such as reeds, clamps, screws, etc. are loosened and displaced, which affects Sumida. The quality of the image, and the volume of the optical engine 2 of the present invention can be further reduced by omitting these positioning mechanisms. In a preferred embodiment, the material of the housing 21 can be plastic, which can be molded or shot. It can also be produced by | g metal, which can be produced by extrusion. However, the shell 21 may also be made of other materials. The material of the mineral film layer 23 of the reflective material may be silver. Chromium, Lu, Platinum, or other good reflective materials can be formed on the reflective plane 2111, 2121, 2122 by evaporation (Sputtering), sputtering (Chemical Deposition) or other methods, and its coating layer 23 The thickness may be a single layer or multiple layers. Traditionally, due to the light-gathering effect of the lens group 24, a thicker or more coating layer 23 needs to be plated on the reflection plane 2122 closer to the lens group 24. Avoid light attenuation due to absorption or scattering, and further improve the light reflectivity, and also need a flat and smooth reflection surface. For the reflection layer 2111 farther from the lens group 24, the coating layer 23 on it can be Relatively thin. 'Please refer to Figure 4 for a preferred embodiment of the optical engine manufacturing process for coating reflection of the present invention, including the following steps: Step 31) Design an optical engine and make the casing of the optical engine Human pages (please note and use continuation pages when the invention description page is insufficient) 13 The materials on the inner side wall are provided by _and_ several reflection planes that should be set by Hu Xiaolin according to the optical engine. (Step 32) Mold the shell with a mold, such as casting with a mold, or making the shell with a mold-lobed L, or other processing methods such as a milling machine or CNC machine tool) Mold the housing part of the optical engine. (Step 33) If necessary, for example, a higher-resolution optical scanner needs a flatter reflecting surface, the surface of the reflecting plane of the housing can be smoothed. Processing, such as polishing or grinding. (Step 34) If necessary, the number of coating layers to be evaporated can be determined according to the actual reflectance required. (Step 35) Evaporation, sputtering, chemical deposition or other The processing method forms a predetermined number of mineral film layers on the reflection plane. (Step 36) If necessary, the coating layer may be covered with a protective surface of a protective material to prevent the coating layer from being damaged or scratched. The protective material is a high molecular weight polymer such as PE or PV film. (Step 37) Completing an optical engine with a specific reflectance In other embodiments described below, since most of the components are the same or similar to the foregoing embodiments, the same or similar components will be given the same name and number It will not be repeated, and only an English letter number is added after the original number number to distinguish it. Please refer to FIG. 5, which is another preferred embodiment of the casing of the optical engine of the mineral film reflection of the present invention. In order to facilitate the actual production of the housing 21a at the time of demolding 0 (the invention description page is insufficient, please note and use the continuation page) > for convenience in this preferred embodiment, the housing 21a is divided into one After the lid body 213 and a body 214 are separately manufactured, the two are assembled to form the casing 21a. The cover body 213 is further provided with a light source base 2131 for receiving the light source 22, and a narrow light-transmitting groove 2132 for light to enter the housing 21a. At the corresponding positions where the main body 214 and the cover 213 are combined, there are provided a plurality of corresponding fastening structures 2133, 2142 (such as the hooks and recessed holes, etc.), so that the main body 214 and the cover 213 can be fastened by the fastening. The structures 2133, 2142 are directly snap-fitted with a locator. Please refer to FIG. 6 and FIG. 7. In still another preferred embodiment of the body 21b of the coated reflective optical engine of the present invention, the housing 21b is also composed of a cover 213b and a body 214b. Make up. At the corresponding positions where the main body 21 牝 and the cover 213b are combined, a plurality of corresponding latching structures of the hooks 2133b and the recessed holes 2142b are also provided. The difference is that the main body 214b of this embodiment is provided with the light source base 2141b for receiving the light source 22, and the cover 213b is provided with the narrow light-transmitting groove at a position corresponding to the light source base 2141b. 2132b for light to enter the housing 2b. Preferably, the body 214b can be produced by aluminum extrusion or cold extrusion and can be made of metal. The part of the cover 213b can be produced by plastic injection or molding, and can be made of metal or plastic material. Please refer to FIG. 8. In a further preferred embodiment of the housing 21c of the optical engine of the key film reflection of the present invention, the housing 21c is also composed of a cover body 21 and a body 214c.
