Description of the Invention: [Technical Field] The present invention relates to a paper feeding device, and more particularly to a paper feeding device having a gear assembly capable of fixing a hinge position. [Prior Art] A paper feed roller used in a conventional paper feeding device is attached to a shaft body, and both ends of the shaft body are fixed to a paper feeding device. In order to avoid axial movement, the ends of the shaft body are usually formed with annular grooves, and the E-shaped ring can be installed on the annular groove, thereby rotatably fixing the shaft body to the shaft body and preventing the shaft. The body moves along the axial direction to cause looseness. The disadvantage of using an E-ring to secure the shaft is that it is time consuming. If other parts need to be attached to the shaft, the number of E-rings used must be increased. In addition, the assembly, removal and disassembly of the E-ring can be achieved by special tools or jigs, and the disassembled ring may be damaged, so the disassembled E-ring is usually not available. Used again. Therefore, the provision of a paper feeding device that does not require the use of an E-ring to secure the shaft body is a solution to be achieved by the present invention. SUMMARY OF THE INVENTION Therefore, the purpose of the present invention is to provide a paper feeding device that does not require an e-shape to fix a shaft body, and the shaft system is fixed by a component such as a gear to facilitate assembly and reduction. The effect of the number of parts. In order to achieve the above object, the present invention provides a paper feeding device package 4 1363701 comprising a housing, a rotating shaft, a roller and a gear, a first carrying portion and a second carrying portion. The housing contains the housing. The rotating shaft has a first end portion and is rotatably disposed to be attached to the first carrying portion, and the second end portion is attached to the It portion. The first end roller is sleeved on the rotating shaft, and the roller is driven by the rotating shaft: two bearing portions. Paper. The gear assembly is sleeved with the second end portion for feeding a gear assembly including a gear portion and a connecting portion for relaying the force to the rotating shaft. The second end is fixed to the second carrier of the housing. To be rotatable, the rotating shaft can be easily placed on the housing by the gear assembly, solving the problems of the prior art. The above description of the present invention will be more apparent and understood. - Embodiments Fig. 1 shows a side view of a sheet feeding device in accordance with a preferred embodiment of the present invention. Fig. 2 is a partial front elevational view of a paper feeding device in accordance with a preferred embodiment of the present invention. Fig. 3 shows the gear assembly of Fig. 2: The present invention is shown in Figs. 1 to 3.
