Description of the Invention: 'Technical Field of the Invention>> The present invention relates to a paper feeding mechanism having a paper feeding mechanism, and particularly to an adjustable feeding angle. [Previous technology #f] In the current era of rapid development of science and technology, scanning, printing, faxing and photocopying electronic devices with paper-infrared (10) become indispensable for modern people's life: part of the 'and deep people' Enterprise and home users, the degree of f (4) In the past few years, the function of the paper feeding mechanism is mainly to feed the documents into the electronic device to scan, copy, digitally store or remotely transfer the file contents. The mechanism includes an input tray, a casing and a paper feed wheel axle. Between the input tray and the case = 2: placed on the input tray, sliding into the paper feed port by gravity, so that the top can drive the contact. Since the paper feed roller shaft is a non-slip surface, when the paper feed roller shaft rotates, the inside of the engine casing, so that the electronic device makes a copy or a broom, the angle between the paper feed trays of the conventional paper feed mechanism is fixed. Paper yesterday ^1 square. The height of the input tray and the casing is variable, causing the sliding into (4) when the contact is tight, it is easy to cause more, and the degree of contact between the axles is not. When the paper is in contact with the feed wheel shaft or the contact is poor, it is easy to open the muitipiefeed. The paper and the paper feed wheel shaft are not rushed into a miss feed. SUMMARY OF THE INVENTION There is a turtle here, and the θ of the present invention provides a point at which the paper feed angle can be automatically adjusted. In order to improve the multiple feed and the miss feed, according to the purpose of the present invention, the paper feed can automatically adjust the feed angle 5

When the paper weight is heavier, the paper is fed. The larger the angle 0 is, the smaller the paper re-feeding angle θ is. A few sheets of paper are placed on the first tray 210 and carried by the tray 110. The paper is inserted into the paper tray with the rotation axis of Fig. 2: The fulcrum rotates. The end of the elastic body abuts against the surface of the casing 2GGa, and the other end abuts the paper feed tray 110. The new one is drawn as shown in Fig. 3, when the paper is placed on the input tray 110, the weight of the paper is used.

The balance of the paper, therefore, the increased paper weight causes the input tray 110 to continue to rotate downwards, while • continue to compress the elastomer until the second elastic restoring force generated by the elastomer deformation and the weight of the loaded paper are obtained. New balance. At this time, the paper feed angle Θ is /?, and Θ is larger than α. That is, by the change in the elastic restoring force of the elastic body, when the weight of the paper becomes heavier, the paper feeding angle <9 becomes larger, and when the weight of the paper becomes lighter, the paper feeding angle Θ becomes smaller. . * Second Embodiment Referring to Figure 5, there is shown an exploded view of a paper feed mechanism that automatically adjusts the paper feed angle in accordance with a second embodiment of the present invention. The paper feeding mechanism 300 is different from the paper feeding Φ structure 100 of the first embodiment in that the elastic body and the side plate 155 are different from each other, and the same reference numerals will be used throughout the same reference numerals and will not be described again. As shown in Fig. 5, the elastic system in the second embodiment is a resilient piece 151 having one end fixed to the side plate 155 and the other end abutting against the housing 200 of Fig. 2. The elastic piece 151 has a resilient elastic force as the compression spring 121. Therefore, when the weight of the paper changes, the force of pressing under the gravity of the paper can be balanced with the elastic force of the recovery, thereby adjusting the paper feed angle Θ. For the third embodiment, please refer to FIG. 6 , which shows the third embodiment according to the present invention. An exploded view of a paper feed mechanism that automatically adjusts the feed angle of an embodiment. The paper feeding mechanism 400 is different from the paper feeding mechanism 100 of the first embodiment in that the elastic body and the side plate 165 are different from the same reference numerals and will not be described again. As shown in Fig. 6, the elastic system in the third embodiment is a torsion spring 161 having one end fixed to the side plate 165 and the other end abutting against the casing 200 of Fig. 2. The torsion spring 161 has a resilient elastic force as the compression spring 121. Therefore, when the weight of the paper changes, the force of pressing under the gravity of the paper can be balanced with the elastic force of the recovery, thereby adjusting the feed angle 8
