The second end portion 24 extends through the second hole 14A. As shown in FIG. 3, the gear assembly 30 is inserted into the second hole 14A of the first carrier portion 14 from the outer side of the housing 1 , and the elastic hooks 341 and 342 of the connecting portion w of the gear assembly 3 pass through the second hole 14A. The buckle is attached to the second carrier portion 14. One of the outer edges 34 of the connecting portion μ of the gear assembly 30 abuts against an inner wall 14B of the second hole 14A of the carrier portion 14. The gear assembly 30 faces the housing 1 - the surface has only a plurality of projections 31A for contact with the housing 10, thereby reducing the friction generated when the gear assembly 3 is in contact with the housing 10. Figure 4 shows a cross-sectional view along the line of Figure 3. As shown in Figure 4, the hollow body 32E has a -D-shaped hole 32De, and the second end portion of the shaft 2 has a D-shaped cross section 24D, which is D-shaped. The hole 321) is adapted to fix the gear 纟 and the member 30 is on the rotating shaft 20, and the rotating shaft 2 〇 can be driven by the gear assembly 3 。. In addition, the gear assembly 30 can also be used using a stop screw or other means. It is fixed to the rotating shaft 20. With the above design, the rotating shaft 20 can be fixed to the casing 10 or can be rotated by the gear assembly 3〇. 201111182 The operation mode of the paper feeding device of the present invention will be described below. The drive gear 90 of a motor (not shown) drives the gear assembly 3 through the tooth portion 32B. The gear assembly 30 transmits the belt 80 and the teeth 32A through the tooth portion 32A. Therefore, the rollers 40 and 40' are driven passively. The rollers 70 and 70 are synchronously rotated to feed the paper § through the scanning areas of the scanning modules 5 and 5, so that the scanning modules 50 and 50 can capture the image of the paper S. With the paper feeding device of the present invention, Can be used without the need for tools The gear assembly is rotatably disposed in the housing by the gear assembly, and the connecting portion of the gear assembly can function as a bearing. Therefore, the E-ring and the bearing can be omitted compared with the prior art, and The rotating shaft does not need to be turned to form an annular groove. In addition, the precision of the shaft hole fitting after the gear assembly is assembled can reach the level of the prior art. Moreover, the removal of the gear assembly does not require tools, and the user only needs to press The two elastic hooks are brought close to the gear assembly. Therefore, the gear assembly of the present invention has the advantages of quick assembly and accuracy without loss of material and processing cost.
