579641. Description of the invention (1) The invention is about a file transfer scanning mechanism and a special scanning mechanism. Difficult to transfer documents to Nandu, the document transfer agency. Please refer to Figure 1 of the younger brother. η λ〆a has no intention of entering the organization. , ^ 结构 1〇 系 包 3 A file transfer mechanism housing 112 ,: transmission = :, 114b, 114c, three idler wheels n6a, " 6b, " 6c-pass one: \ ^, a split sheet 120 A file loading roller 122 and a motor 4. The motor 124 is located inside the casing 12 of the document transfer mechanism. The document loading roller 122 is also located inside the casing 12 of the document transfer mechanism, and is used to enter the document 150. The separating roller 1 1 8 and the separating plate 1 2 0 are both arranged inside the casing 1 1 2 of the document conveying mechanism, and the separating roller 丨 丨 8 will bear on the separating plate 120, and the separating roller 118 and the separation plate 120 can divide a plurality of documents 150 stacked between the separation roller 1 1 8 and the separation plate 120. Multiple sets of transmission rollers 114a, 114b, 114c and idler wheels 116a, 116b, 116c are respectively arranged inside the file transfer mechanism housing 112, and surround the motor 124. Each set of transmission rollers 114a, U4b, 114c and the idler wheels 116a, 116b, 116c can hold the document 150, and the transmission rollers 114a, 114b, 114c can be driven by the motor 124. Next, the file transfer path will be described. The file loading roller 1 2 2 will make the file 1 50 enter the file transfer mechanism housing 1 1 2 and the file 1 50 will pass the file loading roller 1 2 2 'It will move between the separation roller 1 1 8 and the separation plate 1 2 0, and with the design of the separation roller 1 1 8 and the separation plate 1 2 0, only a single document 150 can be allowed on the separation roller 118 and the split plate 120 are advanced. Documents 1 5 passed between the separation roller 1 1 8 and the separation plate 1 2 0

9520twf.ptd Page 5 579641 V. Description of the invention (2) It will move to the position between the driving rollers 1 1 4 a, 1 1 4 b, 1 1 4 c and the idler 1 1 6 a, 116b, 116c in order. At this time, the transmission rollers u 4a, U4b, and 114c, and the idler wheels 116a, 116b, and 116c will clamp the file 150, and drive the file 150 to continue to move forward until the file 5 moves to the housing 1 of the file transfer mechanism. 1 to 2 outside. In the above-mentioned document transfer mechanism 1 10, since the plurality of sets of transmission rollers 114a, 114b, 114c and idler wheels 116a, 116b, 116c are arranged around the motor 124 in pairs, respectively, and in order to pass the divided rollers 118, The document between the split plate 1 2 0 can be smoothly moved to the transfer roller 丨 丨 4 a and the idler 1 1 6 a, the split roller 丨 丨 8 and the split plate 丨 2 〇 The configured height is still It must be higher than the positions where the transfer rollers 1 1 4 a and the idler wheels 1 1 6 a are configured, so the motor 1 2 4, the split roller 1 1 8, the split plate 1 2 0, the transfer roller 114a, The arrangement of 114b, 114c and idler wheels 116a, 116b, 116c will cause the height of the document transfer mechanism 110 to be very high. Furthermore, since the file transfer mechanism 1 10 needs to use multiple sets of transfer wheels 丨 4 a, 1 1 4 b, 1 1 4 c and idler wheels 1 16a, 116b, 1 1 6c to transfer files 丨 50, The design coordination of the mechanism is even more complicated and difficult to design. In addition, when transferring files 150, 'multiple sets of transfer wheels 1 1 4 a, 1 1 4 b, 1 1 4 c and idler wheels 1 1 6 a, 116b 116c contact only a very small area of the file 150, so it is easy This caused the transmission of the file 150 to be bad, and even caused the file 501 to get stuck inside the file transfer mechanism 110. It is therefore an object of the present invention to provide a file transfer mechanism that can effectively reduce the size and height of the file transfer mechanism.

579641 V. Description of the invention (3) Another object of the present invention is to provide a file transfer mechanism, which can simplify the design cooperation of the file transfer mechanism and reduce the cost. A third object of the present invention is to provide a file transfer mechanism that can improve the quality of file transfer. In order to achieve the above and other objects of the present invention, a document transmission type scanning mechanism is provided. The document transmission type scanning mechanism includes at least a document transmission mechanism and a scanning module. The file transfer mechanism is used to transfer a file, and the file transfer mechanism includes at least a transfer roller and a plurality of slave rollers, wherein the slave roller is supported around the transfer roller, and the file is transferred between the transfer roller and the slave roller. The scanning module is used to scan the document transmitted to the document transfer mechanism, and the scanning module includes a light source, at least one reflector, a lens, and an optical sensing element, wherein the light source is used to irradiate the document and irradiate the document. An image will be generated at the place, and the image will be projected on a mirror. The mirror will make the image of the document projected on the lens. After the image of the document is refracted by the lens, it will be projected on the optical sensor. The optical sensing element is, for example, a charge combining element or a complementary metal-oxide semiconductor image sensing element. The light source is, for example, a cold cathode tube. According to a preferred embodiment of the present invention, the document transmission mechanism further includes a belt, which is wound on the slave roller, and the document is transmitted between the transmission roller and the belt. The friction between the transmission roller and the file is greater than the belt and the file. Friction. According to a preferred embodiment of the present invention, the document transfer mechanism further includes a splitting roller and a splitting plate. The splitting roller is supported on the splitting plate, and the space between the splitting roller and the document contacting the splitting roller is The friction is greater than

9520twf.ptd Page 7 579641 V. Description of the invention (4) The friction between the split roller and the multiple documents between the split roller and the split is greater than the friction between the split and the documents contacting the split . The document is transferred between the transfer roller and the slave roller after passing between the split roller and the split plate. According to a preferred embodiment of the present invention, the document transmission mechanism has a first side and a corresponding second side, the document enters the document transmission mechanism from the first side, and the document transmission mechanism further includes a motor, Located near the second side in the document transfer mechanism, the motor is used to drive the transfer roller. In summary, since the motor, the transfer roller, the split roller, the split plate, and the document loading roller are arranged horizontally, the height of the document transfer mechanism can be significantly reduced. In addition, since the file transfer mechanism uses a transfer roller and multiple slave rollers to transfer files, the design of the mechanism can be simplified. In addition, because the transmission roller contacts a large area of the file, when the file is transmitted by the transmission roller, the file can be surely transmitted to improve the scanning quality. Furthermore, since the document transfer mechanism can also be equipped with a belt to wind around multiple slave rollers, and the belt and the transmission roller system contact a large area of the document, the document can be transmitted more reliably by the cooperation of the transmission roller and the belt, and It can improve the scanning quality, and also avoid the situation that the file gets stuck inside the file transfer mechanism.
