The specific embodiment
Address other technology contents, characteristics and effect about before the present invention, in the detailed description of following cooperation preferred embodiment with reference to the accompanying drawings, can know to present.
Before the present invention is described in detail, be noted that in the following description content similarly assembly is to represent with identical numbering.
Fig. 1～Fig. 3 has disclosed a preferred embodiment of the present invention, the preferred embodiment provides a kind of image processing system, chopping machine for example, duplicator, paper deviation correction mechanism in the device such as scanner in the paper feed process, in order to the paper that deflection takes place in the feeding process is corrected alignment, in order to avoid the formation effect and the quality of influence diagram picture.
This deviation correction mechanism 100 includes a driving roller 10, and the flower wheel 11 that cooperates with it.This driving wheel 10 drives transmission by a motor (scheming not shown), and forms clamping gap (nip) with flower wheel 11, in order to transmit paper.
This deviation correction mechanism 100 also comprises as shown in Figure 2 a correction part 12.This correction part 12 has the rotating shaft 121 on the housing (not shown) that is installed in image processing system, and is installed in the alignment of one in this rotating shaft 121 element 122, has an alignment part 124 on this alignment element 122, and this alignment part 124 is a plane.Because this alignment element 122 is positioned at the front end in above-mentioned clamping gap, this makes that its supply side (feeding edge) can touch this alignment element 122 earlier when paper is transmitted, and this moment, this was in the correction position to homogeneous component 122.When homogeneous component 122 was in the releasing position, this alignment element 122 rotated, and allows paper pass through this alignment element 122.Then enter this clamping gap and transmit the downstream position that paper transmits in this image processing system by driving wheel 10 and flower wheel 11.
When the paper S that is fed takes place when crooked, deflection one side of its supply side (a leading side) can touch this alignment element 122 earlier, and under the stopping of alignment element 122, a side of the supply side deflection of paper S can be stagnated.Simultaneously, paper S constantly is fed, and the opposite side of its supply side (fall behind a side) also touches this alignment element 122 then, this moment paper S be subjected to alignment element 122 stop not before.At this moment, paper S still constantly is fed, and makes paper S can form a bending (loop, not shown) near supply side, and when the supply side of paper S pasted together in this alignment element 122 fully, paper S was aligned.Meanwhile, the paper S in the feeding imposes on the application force of alignment element 122 also in continuous increase, to such an extent as to this paper is broken through stopping of this alignment element 122, enters in the clamping gap of driving wheel 10, flower wheel 11, is sent into downstream position by this two roller.
In order better to correct the effect of deflection, and can make this alignment element 122 after correction is finished for the first time, automatically revert to original correction position to form repeatedly circulation correction, this deviation correction mechanism has with correction part 12 bonded assemblys one orders about part, with so that correction part 12 after not having paper feed or paper to be aligned to correct deflection and passing through fully, this alignment element 122 remains in above-mentioned correction position always.
For instance, this torsion spring 123 orders about part as one, and as Fig. 1, Fig. 2 and shown in Figure 3, goes back socket one torsion spring 123 in rotating shaft 121, in order to drive the front end that these alignment element 122 maintenances trend towards the clamping gap of this driving wheel 10, flower wheel 11.On the coupling end 125 of this torsion spring 123 and the image processing system housing (not shown), 126 of its drive ends are connected with the portion of being driven 127 of alignment element 122.So, this coupling end 125 can be fixed on the image processing system housing (not shown), and this drive end 126 applies resistance can for alignment element 122, make when paper need be by this alignment element 122, can not only will to overcome stopping of this alignment element 122, also will overcome the resistance that torsion spring 123 applies.The correction of paper and the process of passing through are existing aforementioned.When treating paper S by this alignment element 122, the resistance that torsion spring 123 applies can make this alignment element 122 be returned to original correction position, in order to carrying out correction operation next time.
In the correction process, the supply side of paper only can contact with the planar registration portion 124 of alignment element 122, and in correction process and the transmission paper process, the speed unanimity of roller can not cause damage to paper S.And, this deviation correction mechanism, simple for structure, avoided the sensor mentioned in the background technology etc. to survey the device of deflected position, and the more change of control system and driving system in the image processing system that brings thus, thereby can reduce the cost of image processing system and can make becoming of whole device compact more.
Need to prove that paper well straightening of the present invention mechanism not only can be applicable to also can be used for chopping machine, automatic paper feeder in the paper feed mechanism of scanner, in the machines such as duplicator, and can be used for the single face paper feed mechanism, also can be used for two-sided paper feed mechanism.Wherein, described paper can be document, but analogues such as load image such as photo.Choosing of the parameter of torsion spring 123 should deciding according to the medium of the image chosen carrying.
The above, it only is preferred embodiment of the present invention, when the scope that can not limit the invention process with this, promptly the content of putting down in writing according to claim of the present invention and description of the invention has generally been done simple equivalent and is changed and modify, and all still belongs within the claim of the present invention institute covering scope.In addition, summary partial sum title only is the usefulness that is used for assisting the patent documentation search, is not the interest field that is used for limiting the present invention.
