Explanation of the invention (3) The contact method of the roller 11 4 and the idler 11 8 is a point contact method. For the file 150, it is easy to cause the transmission failure of the file 150. , Resulting in poor scan quality. Therefore, one object of the present invention is to provide a transmission mechanism. By reducing the number of total rollers of the transmission mechanism, the space occupied by the total rollers can be reduced, and the volume of the paper feeder can be effectively reduced. Another object of the present invention is to provide a transmission mechanism for transferring files by means of face-to-face contact. Therefore, the transmission method can more surely contribute to the quality of subsequent drawing. To achieve the above and other objects of the present invention, a mechanism is proposed including three transfer rollers, an idler pulley, a belt, and an elastic moving member. The belt is wound on the transmission roller, and the transmission roller 2: the two elastic members can drive the idler, so that the idler applies the belt to the belt when the paper feeder pushes and the number of idlers), so the total can be reduced Force, and this friction can move the file. In addition, by means of a frictional contact method, the contact between the belts and the wheels is transmitted in a face-to-face manner, and the surface friction force of the contact is greater than that of the idler = belt and the file, so the file transmission method can be more reliable. Then the bomb of L 9320twf.ptd Page 6 552233 V. Description of the invention (4) Sexual force can push the idler to the direction of the belt, which can restore the slack belt to the unslack condition, so that the transmission mechanism can continue to operate normally. In summary, since the transmission mechanism of the present invention can reduce the number of total rollers (including transmission rollers and idlers), the volume occupied by the total rollers can be reduced, and the volume of the paper feeder can be effectively reduced. The transmission mechanism is driven by the surface contact transmission method, so the file can be in actual contact with the belt and the idler, so the transmission of the file is more reliable. In order to make the above and other objects, features, and advantages of the present invention more comprehensible, a preferred embodiment is exemplified below in conjunction with the accompanying drawings, which are described in detail as follows: Symbols of the drawings: 3 0 · 1st distance 4 0 2nd distance 11 0, 2 1 0: feeder 11 2: tray 11 4: transfer roller 11 8: idler 11 6, 2 1 6: scanning port 120, 220: 1st 1 conveying direction 1 2 2, 2 2 2: paper feed wheel 124: sorting plate 126: sheet separation wheel 1 2 8: output tray 1 3 2, 2 3 2: scanning module

As shown in FIG. 3B, the document 250 can move the idler gear 226 to the right, and at this time, the elastic member 2 2 7 will also generate an elastic force to give the lever shaft 2 1 9, so that the idler gear 22 6 applies a positive force. On the document 25, the document 25 () and the belt 229 are caused to generate a frictional force, and the document 250 is advanced by the frictional force. Then, the document 250 passing between the belt 229 and the idler 226 will gradually move to a third conveying direction 260. The contact method of the document 250 with the belt 229 and the idler 226 is a surface contact method, and the belt 229 and the document 250 The friction force of the contacted surface is greater than the friction force of the idler 226 and the surface contacted by the document 250. In addition, the elastic member 2 2 7 can move the idler 2 2 6 to the direction of the skin ▼ 229 by its own elastic force. It can also apply a forward force of 250 on the file, and the 250 can be moved to the belt 229 and the idler. 226 spacing. Among them, the elasticity of the elastic member 2 2 7 can be used to adjust the distance of the space, so that the space can accommodate a thicker document 250. '凊 Refer to Figures 3C and 3D.
