The shaft 36a, the active roller is sleeved on the transmission shaft, and the driven roller 33a and the driving roller 3 have a shortcut shaft 3U, and the door is located at the gate, and the roller positioning structure is Connected to the opening 333a, the flexible shaft 31a is integrated and the shaft 313 is made of a steel material having a spring shape and the axial winding W is also extended. The flexible arm 32a is also made of a steel material. Elastic' and when the driving roller 3 applies pressure to the driven roller 33a, the third portion of the arm I provides a reaction force to the first portion 321a of the flexible arm 32a. Qing Cang read "Figure 2", which shows the partial structure design of the conventional driven roller, including the driven roller llb, the active roller 12b and the annular spiral worm, the annular coil spring 15b is embedded in the driven roller shaft 14b. When the paper is guided through the section of the rolling roller 11b and the driving roller 12b, the annular coil spring is said to provide a positive force to the driven roller shaft 14b. The forward force is not evenly distributed to the driven roller shaft 14b, which causes the driven roller 11b to have an offset space, which causes the driven roller llb to be unstable and affects the paper output quality. Please refer to "3rd" The illustrated figure is a driven roller device and its elastic structure disclosed in U.S. Patent Publication No. 2005/0012264. The M315163 includes a driven roller lie, a driving roller 12c, a driven roller shaft 14c and a torque. The torque member 30c is wound around the driven roller shaft 14c, and the two arm ends of the torque member 3〇c are respectively placed on the baffle 50c. Therefore, when the driving roller 12c and the driven roller lic roll each other, the torsion member 3Ge Will produce tension and positive force Driven roller l_lc 'to counterbalance the pressure exerted by the driving roller Uc, but the design of its structure remains elastic moment will generate invalid' a positive force is dispersed to be administered to the driven roller llc. [New content] The conventional technology can not effectively save the volume to adapt to the narrow interval, and the π force generated by the force applied to the force cannot fully act on the driven roller, resulting in the paper being unable to pass the paper smoothly, and the paper is folded. More ambiguous, the production of sulphur sulphur is rising. In view of the above-mentioned topic, the purpose of this creation is to provide a paper feeding mechanism according to the present solution, which includes a pedestal, a arbor and The complex 2 torque member has a driven roller on the base, the shaft should be driven from the position of the new wheel, and the driven roller is abutted against the main wheel. The paper feeding mechanism S is disposed on the base. A plurality of torsion parts, the sleeves are placed on the set rods, each twisted bamboo and two bamboo, the lion's secret crane thread _ narrow occasion, the paper mechanism 'can save volume' and applied to the space force can be * people / Ί The positive force of the paper and the touch roller, the positive contact === on the moving roller, called the 'between the driven roller and the active roller', the effect component is generated, and the driven roller has the bump feature. M315163 helps the paper to smoothly feed the paper, and the parts are simple and can save the order, and the shaft handles the money. The above and other objects, features and advantages of the present invention will become more apparent and obvious.
