Next the operation situation of automatic paper feeder 2 is described, please refer to Fig. 2 and Fig. 4, when automatic paper feeder 2 running, engine installation 22 is driven and produce power, and drive axle drive shaft 201 that it is rotated power transmission to axle drive shaft 201 by double-layer gear 241, but get paper driving roller 203, do not synchronize rotation with axle drive shaft 201.When axle drive shaft 201 driven and while rotating, propeller shaft sleeve 202 is synchronizeed rotation with axle drive shaft 201, and the driving inclined-plane 2021 on propeller shaft sleeve 202 and driving projection 2022 are along with axle drive shaft 201 rotates, now, drive a first surface 2041A of inclined-plane 2021 pushing and pressing slide bumpings 2041 and make slide bumping 2041 close to getting reel cover 2031, and drive a first surface 2022A of projection 2022 to push against one second 2041B of slide bumping 2041 and slide bumping 2041 is rotated toward a hand of rotation C.Therefore, sliding bevel 2042 with get that paper inclined-plane 2031A contacts and 2043 pushing and pressing of slip stop section are got paper stop section 2031B and made to get paper driving roller 203 and rotate, simultaneously, because drive belt 206 is surrounded on, gets paper driving roller 203 and get the passive roller 205 of paper, make to get the passive roller 205 of paper and get paper driving roller 203 and synchronize and rotate and to get chart speed degree feed documents D, as shown in Figure 5.
Get the passive roller 205 of paper and get the lasting rotation of paper driving roller 203, make file D continue to be fed to get chart speed degree, when file D is fed to the position of paper feed roller 21, the front end of file D contacts with paper feed roller 21, the front end of file D is fed to paper feed speed by paper feed roller 21, and wherein paper feed speed is greater than and gets chart speed degree.Now, the rear end of file D still contacts with paper taking module 20, and therefore, the file D being fed with paper feed speed drives paper taking module 20, make to get the passive roller 205 of paper and rotate with paper feed speed with getting paper driving roller 203, and axle drive shaft 201 and propeller shaft sleeve 202 still rotate to get chart speed degree.
Owing to getting paper driving roller 203, to be greater than the speed of axle drive shaft 201, rotate, so the speed that slide bumping 2041 rotates is greater than the speed that propeller shaft sleeve 202 rotates, makes slide bumping 2041 separated with the first surface 2022A that drives projection 2022 and no longer pushed against.Slide bumping 2041 continues to rotate and makes one the 3rd 2041C of slide bumping 2041 be contacted with second 2022B that drives projection 2022, now, the rotation of slip cap 204 is activated stopping of projection 2022 and slows down, make to get the sliding bevel 2042 of getting paper inclined-plane 2031A pushing and pressing slip cap 204 of reel cover 2031 and slip cap 204 is away from get reel cover 2031, as shown in Figure 6.Therefore slip cap 204, axle drive shaft 201 and propeller shaft sleeve 202 dally and do not hinder the rotation of getting paper driving roller 203 and getting paper driving roller 2031, so that file D is fed.
