This auxiliary wheel 23 has two, and is located in the axial of two auxiliary wheels 23 with an axostylus axostyle 27.The two ends of this axostylus axostyle 27 are defined as first end 271 and second end 272, and wherein this second end 272 is equipped with a belt pulley 273.This auxiliary wheel 23 is between this auxiliary wheel 22 and tell between the paper roller 24.
This drive unit 31 mainly comprises a motor, and motor shows in the drawings, a plurality of driving pulley 32,33,34,35 and many driving belts 36,37,38,39.
The output shaft of this motor does not show that in the drawings itself and this driving pulley 32 connects to be established, and this driving pulley 32 is connected by a driving belt 36 with another driving pulley 33.In addition, the side at this driving pulley 33 is installed with another driving pulley 331 that rotates synchronously.
Shown in Fig. 2,3, this driving pulley 331,34,35, and be positioned at the non-return device 41 of first end 251 of this axostylus axostyle 25, this non-return device 41 also is a driving pulley, just constitutes tetragonal four summits, and with this driving belt 37 around the periphery.
It should be noted that, this driving pulley 34 is to be an idle pulley, with so that the transmission force of this driving belt 37 turns to, and a side of this driving pulley 34 is installed with a gear 341 that rotates synchronously, this gear 341 and gear 43 engagements that are installed in these non-return device 41 1 sides.
One side of this driving pulley 35 is installed with the gear 351 that can rotate synchronously, gear 53 engagements of establishing that connect on the axostylus axostyle 52 of this gear 351 and paper-feeding roller 51.
Shown in Fig. 2,4, on this belt pulley 253 and belt pulley 264, this driving belt 39 is then by the periphery of winding at non-return device 42 with the belt pulley 273,283 of second end of axostylus axostyle 25 by winding for this driving belt 38.
As shown in Figure 1, this is told between the paper feed end 11 and paper delivery end 12 that 20 groups of paper/paper advance mechanisms are located at this body 10.And paper-feed 21 contiguous these paper feed ends 11, this tells paper roller 24 contiguous these paper delivery ends 12.This paper-feed 21, auxiliary wheel 22, auxiliary wheel 23 and tell paper roller 24 each some and enter in this paper feed passage 13.
The paper feed action
Be illustrated in figure 5 as paper feed action schematic diagram, wherein scan the paper of finishing and broken away from scanning area, and next paper do not enter scanning area S.When the motor that does not show is in the drawings just changeing, i.e. clockwise direction among the figure, this driving pulley 331,34,35, and this non-return device 41 all produces forward rotation, and the gear 351 that this driving pulley 35 is connected drives and its meshed gears 53 simultaneously, make paper-feeding roller 51 rotate, paper 61 is brought into told among paper/paper advance mechanism 20.Paper will move along the paper feed passage, not show among the figure.
Since between this paper-feed 21 and this auxiliary wheel 22 by driving belt 38 interlocks, so this paper-feed 21 is consistent with the rotation direction of this auxiliary wheel 22.
Because this auxiliary wheel 23 and this paper-feed 21 are by driving belt 39 interlocks, so this auxiliary wheel 23 is consistent with the rotation direction of this paper-feed 21.
It should be noted that, this end of telling paper roller 24 is equipped with a non-return device 41, and the gear that connected of these non-return device 41 1 sides 43 connects the gear of establishing 341 with these driving pulley 34 1 sides and mesh, when gear 341 is just changeing, driven gear 43 counter-rotatings, and the non-return device 41 of this moment is idle running.
Because this belt pulley that the other end connected 283 of telling paper roller 24 and paper-feed 21 by driving belt 39 interlocks, still can be done unidirectional rotation with this paper-feed 21 so this tells paper roller 24.
Thus, this paper 61 just can be deviate from smoothly through paper-feed 21, auxiliary wheel 22, auxiliary wheel 23 and after telling the effect of paper roller 24 equidirectional rotations.
The paper effect of telling behind the cancellation paper feed
Be illustrated in figure 6 as and tell paper action schematic diagram.Behind the cancellation continuous paper-feeding, the cancellation continuous paper-feeding can be reached cancellation action with software by the user, the motor that does not show among the figure counter clockwise direction among the i.e. figure of just reversing, and this driving pulley 331,34,35, and this non-return device 41 all produces backward rotation.
Because the axostylus axostyle 52 of paper-feeding roller 51 is equipped with non-return device, demonstration, and the non-return device of this moment does not in the drawings act on, so the interlock effect of gear 351 and gear 53, can not make paper-feeding roller 51 continue paper tape is advanced to tell paper/paper advance mechanism 20.
Because the two ends of this paper-feed 21 are equipped with non-return device 41 and 42, and each non-return device 41 and 42 is at this moment for idle running, so paper-feed 21 does not rotate.
Because this auxiliary wheel 22 and paper-feed 21 be by driving belt 38 interlocks, and this auxiliary wheel 22 not with other roller interlock, so when paper-feed 21 did not rotate, this auxiliary wheel 22 did not rotate yet.
Since driving pulley 34 with gear 341 with tell gear 43 engagements that paper roller 24 is connected, so when gear 341 counter-rotatings, this gear 43 can just change, and non-return device 41 meeting generation effects this moment, making this tell paper roller 24 is just changeing.
Though this tells paper roller 24, auxiliary wheel 23 and paper-feed 21 by driving belt 39 interlocks, but the non-return device 42 that this paper-feed 21 connected is idle running in positive veer, and this auxiliary wheel 23 is only told paper roller 24 drives, so this paper-feed 21 does not still rotate, auxiliary wheel 23 is told paper roller 24 formation with this just to be changeed.So originally being parked in auxiliary wheel 23 just can shift out automatically with the paper 61 of telling paper roller 24 bottom surfaces.
Therefore, in the time of telling the paper action, motor reverses, and rotates towards former direction in the roller continuation on the scanning area S left side, and does not rotate at the roller on scanning area S the right.So, so that break away from the paper of scanning area and told mechanism of paper and spue.
Simplified embodiment
Demonstrate simplified embodiment of the present invention as Fig. 7,8,9, the present invention does not need four paper-feeding roller with explanation, only needs two paper-feeding roller to get final product.Under Fig. 2, present embodiment has omitted auxiliary wheel, auxiliary wheel and the relevant member thereof of Fig. 2.
As shown in Figure 7, at first motor is just being changeed with turning to of drive pulley 32 and be defined as counterclockwise.At this moment, belt 36, belt pulley 33 and 331, belt 37, belt pulley 34, gear 341, belt pulley 35, non-return device 41 all are rotations counterclockwise.The non-return device 41 that is installed in first end 251 of axostylus axostyle 25 produces to be done in order to drive shaft rod 25 and paper-feed 21 rotations, and axostylus axostyle 25 also drives non-return device 42, the belt 39 of second end 252 that is installed in axostylus axostyle 25, the belt pulley 283 that is installed in second end 282 of axostylus axostyle 28, axostylus axostyle 28 and final roller 24 and is rotated counterclockwise.On the other hand, gear 341 gear 43 that drives first end 281 that is installed in axostylus axostyle 28 is done the clockwise direction rotation with non-return device 41.At this moment, non-return device 41 does not act on, and to allow axostylus axostyle 28 and gear 43 rotation of different directions is arranged.So, can normally carry out the paper feed action.
As shown in Figure 8, in the time will telling the paper action, with the motor counter-rotating, this moment, turning to of belt pulley 32 was clockwise direction.At this moment, belt 36, belt pulley 33 and 331, belt 37, belt pulley 34, gear 341, belt pulley 35, non-return device 41 all are the clockwise direction rotations.Non-return device 41 does not produce effect, so axostylus axostyle 25 and paper-feed 21 do not rotate.On the other hand, gear 341 driven wheels 43 are done rotation counterclockwise with non-return device 41.At this moment, non-return device 41 generation effects are ordered about axostylus axostyle 28 and are done rotation counterclockwise with final roller 24.Axostylus axostyle 28 drive pulleys 283, belt 39 and non-return device 42 are done rotation counterclockwise.At this moment, non-return device 42 does not produce effect, so axostylus axostyle 25 does not rotate.
Therefore, no matter the motor forward or reverse, final roller 24 all is to do the clockwise direction rotation.
As shown in Figure 9, can know among the figure and find out, if paper-feed 21 with tell the both sides that paper roller 24 lays respectively at scanning area S, can reach above-mentioned paper feed/tell paper function.
Effect of the present invention
By described above, the present invention utilizes the motor counter-rotating, and mate gear and non-return device, rotation direction near the roller of paper delivery end is still is keeping the paper delivery direction, thus, even the user cancels continuous paper-feeding midway, the paper that does not break away from form feeding device in real time still can shift out automatically, and it is do not need to pull, so easy to operate and can guarantee that paper is not torn with manpower.
Moreover, adopt the present invention, user can carry out individual scanning and then handle, do not have and paper is partly rested in the form feeding device and the shortcoming that can't take out.
Therefore, the maximum difference of the present invention and known technology is to propose a kind of paper/paper advance mechanism of telling automatically, and it can reach the effect of the paper that spues automatically after the user cancels the paper feed action.
Because the design of transmission mechanism is rich in multifarious variation, therefore, is familiar with this operator under guidance of the present invention, the sequence of positions of above-mentioned each part of permutation and combination is to reach the effect identical with the present invention easily.
