、又，一般的自動送紙機構中，由於與進紙滾筒相接觸 時必須墊以特殊低磨耗或耐磨耗材質，以避免紙張於排出 後、該進紙滾筒再次動作時，因差負載會變大，而導致影 像品質受到影響，然此特殊低磨耗或耐磨耗材質仍會造成: 成本的提高，故顯有改善的必要。 是以，由上可知，上述兩種習知的自動送紙機構，在 實際使用上，顯然具有不便與缺失存在，而可待加以改善 者。 ° 緣是，本發明人有感上述缺失之可改善，乃特潛心研 究並配合學理之運用，終於提出一種設計合理且有效改善 上述缺失之本發明。 本發明之主要目的，在於可提供一種自動送紙機構， ，、係為一種運用太陽行星輪系（Sun and planet wheel) $合彈性元件與差速結構來控制進紙滾筒作向下帶紙之動 ，=達到修改進紙滾筒持續下壓帶紙之目的，藉以取代 〜、、’先單向扭力彈簀式或電子離合式之自動送紙機構，進而 軟簡單且成本更低之方式有效地作到該進紙滾筒的帶 、、、氏動作，並確保影像之品質。 士發明之另一目的，在於可提供一種自動送紙機構， 皙^ .'、、避免該進紙滾筒因負栽的變化而導致紙張影像之品 化=H，故令$進紙滾筒下方騰空，以解決因負載變 :問題，同時亦可解決以往以特殊低磨耗或耐磨耗材質 a之而造成成本提高之缺失。In addition, in the general automatic paper feeding mechanism, because of contact with the paper feed roller, a special low-wear or abrasion-resistant material must be used to prevent the paper from being discharged due to poor load. The image quality will be affected, but this special low-wear or abrasion-resistant material will still cause: The cost increases, so it is necessary to improve. Therefore, it can be seen from the above that the above-mentioned two conventional automatic paper feeding mechanisms obviously have inconveniences and defects in practical use, and need to be improved. ° The reason is that the inventors felt that the above-mentioned defects could be improved. They have devoted themselves to research and cooperated with the application of theories to finally propose a present invention with a reasonable design and effective improvement of the above-mentioned defects. The main object of the present invention is to provide an automatic paper feeding mechanism, which is a method for controlling the paper feed roller to be used for downwardly feeding paper by using a Sun and planet wheel combined with an elastic element and a differential structure. Movement, = to achieve the purpose of modifying the paper feed roller to continuously press down the tape, so as to replace ~ ,, 'first unidirectional torsion spring type or electronic clutch type automatic paper feeding mechanism, which is effective in a soft, simple and cost-effective manner. Take the action of the belt, roller, and roller of the paper feed roller and ensure the quality of the image. Another object of the invention is to provide an automatic paper feeding mechanism to prevent the paper feed roller from being changed due to changes in the load, resulting in a paper image = H, so the bottom of the paper feed roller is emptied. In order to solve the problem of load change: At the same time, it can also solve the lack of cost increase caused by the special low-wear or wear-resistant material a in the past.

Description of the invention ⑹ ___ = 2: The paper feed roller 3 will roll the paper into the first one; the paper path 18 will separate the roll paper. As shown in the fourth and sixth illustrations of Zhang, when the bismuth ancestral war is to be continued, the pan paper tube will be opened on the 9th, and the Putian paper follow the paper feed path 1 8 rotation, $ n <,: 1 Scrolling will roll the paper and take it to Erbei for printing, scanning or faxing. The picture shows' When the paper is brought to the rotary drum 6 Sheets == Cut: The speed is faster than the upper drum 2. Therefore, due to the speed between the second and second idler wheels 15, the two rockers 3 are subject to the elastic element 11 (such as = will be restrained and the paper feed roller 1 will be brought back up because the upper roller 2 and the second The idler 15 will cause the two rocker rods 3 to drive the paper feed roller 3 to take down the paper. During the time between the paper feed roller 1 and the load change, the image quality may be affected, which can be carried out profitably. Finally, when the scanning operation is completed, the aforementioned driving motor 7 is reversed i 1. Therefore, the automatic paper feeding mechanism of the present invention can effectively control the paper feeding roller to perform the downward paper feeding operation. Replaces the traditional unidirectional torsion spring-type or electronic clutch-type automatic paper feeding mechanism, and can solve the image impact caused by the load change At the same time, it can also avoid the lack of excessive cost. 2 Make the action of bringing back up. 3: f 3 pinch of the elastic element 1 1 and two shakes 3 and the paper feed roller 1 559612 5.
