The specific embodiment
Below, the embodiment of the sheet material conveyor that present invention will be described in detail with reference to the accompanying.As shown in Figure 1; It is right with a plurality of conveying rollers of being configured on this transport path that sheet material conveyor 1 has transport path, said transport path have from can carry the paper supply tray 3 of putting many sheet materials to discharge tray 4 with first landline (paper supply route) 8 of U oxbow and second landline (upset route) 21 that turns back from the said paper supply route 8 of nearly hand side direction of discharge tray 4.
Said paper supply route 8 is transport paths that many sheet materials of stow on paper supply tray 3 are separated one by one and see off to platen 5 sides.In addition, the platen 5 that is had via reading device main body 2 from this paper supply route 8 extends, and to read route 9 be continuous with read row's paper route 10 that route 9 links to each other with discharge tray 4 from this.In addition, said paper supply route 8 is provided with first and second guiding parts of the conveying channeling conduct of sheet material (first, second membrane element) M1, M2, and is formed with the curve towards platen 5 bendings.
Saidly read route 8 is formed feeding sheets by the 3rd inboard spigot surface 21b of first outside spigot surface 8a, the first inboard spigot surface 8b and upset route 21 space.On the other hand, upset route 21 is formed the space of feeding sheets by the 3rd outside spigot surface 21a and the 3rd inboard spigot surface 21b.Said first outside spigot surface 8a is set at the mode that can rotate and is rotated on the open-close lid 18 of fulcrum 18a supporting, through carrying out rotating operation along anticlockwise direction among the figure and can opening.In addition, open-close lid 18 disposes and rolls out roller 11, paper feed roller 12 and rotation integratedly.
Said a plurality of conveying roller is to by following component set-up: be used for from what 3 pairs of sheet materials of paper supply tray rolled out rolling out roller 11; The paper feed roller 12 that the sheet material that will have been rolled out is seen off to paper supply route 8; Read preliminary roller to 13 at the side nearby of platen 5 adjustment sheet material; Reading the back roller to (alignment roller to) 14 along what read route 9 feeding sheets; With sheet material to discharge tray 4 row's paper and the upset exit roller that is used to make its upset route 21 that turns back to 15.
Thereby the said roller 11 that rolls out rolls out sheet material contacting with the upper surface of year putting the sheet material on paper supply tray 3 down with adjustment plate 17 butt joint and the state adjusted.In addition, adjustment plate 17 is removed the restriction to sheet material when rolling out rolling out 11 pairs of sheet materials of roller.Paper feed roller 12 and separating component cooperation ground will go out one and see off to paper supply route 8 by rolling out sheet separation that roller 11 rolled out.
The said preliminary roller that reads is made up of driven roller 13a and driven voller 13b 13, reads the back roller and is made up of driven roller 14a and driven voller 14b 14, and exit roller is made up of driven roller 15a and driven voller 15b 15.In this embodiment, read preliminary roller to 13 in position configuration near platen 5, thus, carry out being read the aligning of preliminary roller to this to 13 sheet material by paper supply, and through across platen 5 ground relative read the back roller and carry out the reading of sheet material 14 the time conveying.That is to say, read the back roller to 14 also as alignment roller to the performance function.In addition; Said driven roller 13a, 14a, 15a be prevent and sheet material between skid and make feed motion stable; On plane of revolution, adopt high friction means, driven voller 13b, 14b, 15b become easily the guiding of sheet material, on plane of revolution, adopt low friction means.
In addition; Structure as control system; Dispose and be used to detect sheet material and carried and to put the vacant sensor S1 of the situation on paper supply tray 3, the preliminary roller that reads in paper supply route 8 disposes 13 side nearby and is used to detect the alignment sensor S2 by the end of the sheet material of paper supply.The control part (not shown) that these each sensor S1, S2 and having is used to control the CPU of sheet material conveyor 1 single-piece action is connected; Based on detection signal, control drive motor MOT shown in Figure 2 and first, second magnetic clutch CL1, CL2 from each sensor S1, S2.
Below, the inner structure of said paper supply route 8 is described.On this paper supply route 8, as shown in Figure 1, have from upset route 21 crooked also interflow position (junction of two streams) Js at interflow of upset exit roller 15 extensions, near this junction of two streams J, compare the interval that forms the guide plate material with upstream side widelyer.The said first membrane element M1 is that the upstream side with junction of two streams J is that basic point is set up, leading section extend to this junction of two streams J near.That is to say that near the line that the said first membrane element M1 prolongs with the face that will guide sheet material mode of intersection between said first outside spigot surface 8a and the said junction of two streams J is provided with.In addition, the second membrane element M2 is that to be basic point with said junction of two streams J read preliminary roller to 13 configurations with leading section towards the downstream.That is to say that the line that the said second membrane element M2 prolongs with the face that will guide sheet material is provided with the side face of 13 driven voller 13b or near mode towards the said preliminary roller that reads.Therefore; The side of the second membrane element M2 becomes the inboard guide part of paper supply route 8; The another side side becomes the outside guide part of upset route 21, and the driven voller 13b butt that the front end of sheet material and resin by low friction form also is directed to swimmingly and reads preliminary roller to 13 pressure contact portion.In addition, the said first membrane element M1 under the situation of aiming at thick sheet material, preferred to first outside spigot surface 8a side shifting and the easily material with flexibility of deflection of resilience (コ シ) through sheet material of using.Thus and since can form curvature big to quasi loop, so via the intensity of the resilience of sheet material, the front end of sheet material not can from read preliminary roller to 13 pressure contact portion n1 downstream side fly out, also can correctly aim at for the sheet material that thickness is different.
On the other hand, the second membrane element M2 becomes through the sheet material of paper supply route 8 and the common spigot surface of sheet material through upset route 21, thereby preferred the use has the film material of comparing the little rigidity of deflection with the said first membrane element M1.In addition; As previously mentioned; Read preliminary roller 13 driven voller 13b is formed by the resin of low friction, thereby can also lead the mode of pressure contact portion n1 swimmingly towards side face or near the guiding sheet material of driven voller 13b with the front end of sheet material and driven voller 13b butt via the said second membrane element M2.
Be provided with the first aligning space S P1 in the place ahead of the said first membrane element M1, M2, be provided with second in its downstream and aim at space S P2 with sheet material conveying space wideer than the upstream side of paper supply route 8.First aim at space S P1 with first outside spigot surface 8a of the front that will be positioned at the first membrane element M1 outwardly the direction mode of stretching out form, and be set between the extended line and first outside spigot surface 8a of the said first membrane element M1.In addition, second aim at space S P2 likewise with second outside spigot surface 9a of the front that is positioned at the second membrane element M2 outwardly the direction mode of stretching out form, and be set between the extended line and second outside spigot surface 9a of the said second membrane element M2.
As shown in Figure 4, to aim among the space S P1 said first, the front end of the sheet material of sending here from paper supply tray 3 dock with reading the pressure contact portion n1 of preliminary roller to 13, and edge first outside spigot surface 8a flexure deformation and producing quasi loop, and thus, the rectification sheet material is crooked.In addition; As shown in Figure 6; Aim among the space S P2 said second, the front end of the sheet material of sending here again from upset route 21 dock by second membrane element M2 guiding and with reading the pressure contact portion n1 of preliminary roller to 13, or edge second outside spigot surface 9a flexure deformation and producing quasi loop; Thus, the rectification sheet material is crooked.
In addition, as shown in Figure 1, upset route 21 is by constituting to reading the 3rd inboard spigot surface 21b of preliminary roller to 13 extensions side by side to the 3rd outside spigot surface 21a of junction of two streams J extension with the 3rd outside spigot surface 21a from the upset exit roller to 15.And, on this upset route 21, also be provided with the 3rd and aim at space S P3.As shown in Figure 7, the 3rd aims at space S P3 forms through making near the upset exit roller 15 the 3rd inboard spigot surface 21b to be stretched out laterally.And, dispose tertiary membrane parts M3 along the said the 3rd inboard spigot surface 21b.These tertiary membrane parts M3 with the downstream of upset route 21 be basic point upstream side extend, thus, have via the upset exit roller to 15 derotation then the effect of isolating the sheet material that side downstream turns back.In addition, the sheet material deflection that tertiary membrane parts M3 carries because of trip from it, thus, through becoming easy.
Be arranged on the upset route 21 through aiming at space S P3 the said the 3rd, big and to aim under the situation that can not eliminate amount of alignment among the space S P2 second be actv. to the quasi loop amount.
In said upset route 21, wideer with the sweep of the second inboard spigot surface 9b at paper supply route 8 interflow than its upstream side and outlet side, thus, can carry out the conveying of sheet material swimmingly.In addition, towards forming the interval of the 3rd outside spigot surface 21a and the 2nd inboard spigot surface 21b gradually, thus, can suppress by the skew of the throughput direction of the sheet material of second membrane element M2 guiding with the junction of two streams J of said paper supply route 8 with narrowing down.
Below, based on Fig. 8,, the details of the feed drive of sheet material is described also with reference to Fig. 2 to Fig. 7.At first, read action about the single face of the single face (surface) that reads sheet material P, vacant sensor S1 is the ON state; Promptly detecting sheet material P is carried and to be put in 3 last times of paper supply tray; Drive motor MOT is just changeing driving, and simultaneously, making the first magnetic clutch CL1 is ON (ST1～ST2).Thus, roll out roller 11 and paper feed roller 12 rotation drivings, the sheet material P on the paper supply tray 3 is by paper supply (with reference to Fig. 3).And, when alignment sensor S2 detects the front end of sheet material P, carry out alignment actions 1 (ST3, ST4).
In alignment actions 1, making magnetic clutch CL2 is OFF, stops to read preliminary roller to 13 rotation.Simultaneously, the counting of the drive pulse number of times of beginning drive motor MOT, when pulse number reached the pulse number (pulse A) of regulation, making magnetic clutch CL1 was OFF (ST32～ST33).Thus, roll out roller 11 and paper feed roller 12 temporarily stops.At this moment, the front end of sheet material P docks also flexure deformation with reading the pressure contact portion n1 of preliminary roller to 13, forms thus quasi loop is adjusted front end, and crooked (deflection) corrected.That is to say, above-mentioned predetermined pulse number of times (pulse A) become and from the detection position of alignment sensor S2 to reading preliminary roller to distance 13 the pressure contact portion n1 and the drive pulse number of times that forms the desired cooresponding drive motor MOT of distance that obtains apart from addition to quasi loop.In this embodiment, the distance that forms quasi loop is about 5mm, and the front end of sheet material docks beginning with reading the pressure contact portion n1 of preliminary roller to 13, sends 5mm ground again to and drives (with reference to Fig. 4).
After this alignment actions 1, the front end of sheet material P with read the state that the pressure contact portion n1 of preliminary roller to 13 dock under, making magnetic clutch CL2 is ON (ST5).Thus, read preliminary roller 13 rotations are driven, sheet material P is transferred to platen 5.By the said preliminary roller that reads the 13 sheet material P that carry to platen 5 are advanced along the upper surface of this platen 5, and via read the back roller to 14 and the upset exit roller to 15 to discharge tray 4 row's paper.In the process of carrying along the upper surface of this platen 5, sheet material P is read processing.In addition; Making magnetic clutch CL2 is after the ON; By alignment sensor S2 detect be read preliminary roller to 13, read the back roller to 14 and upset exit roller during to the rear end of the 15 sheet material P that carry, making magnetic clutch CL1 again is ON, and begins the paper supply (ST6, ST2) of next sheet material.
Action is read on two sides about the two sides of reading sheet material P (the table back of the body), detects sheet material P by vacant sensor S1 and is carried when placing paper supply tray 3, and drive motor MOT is just changeing driving, and making magnetic clutch CL1 is ON (ST11～ST12).Thus, rolling out roller 11 and paper feed roller 12 rotates driving and sheet material P is carried out paper supply.And, read action likewise with above-mentioned single face, in the moment that alignment sensor S2 detects the front end of sheet material P, carry out alignment actions 1, the front end (ST13, ST14) of adjustment sheet material P.
During front end through alignment actions 1 adjustment sheet material P, making magnetic clutch CL2 is ON, via read preliminary roller to 13 on platen 5 feeding sheets P and through (ST15).In the process through said platen 5, the surface of sheet material P is read.The sheet material P that has passed through platen 5 via read the back roller to 14 and the upset exit roller carry to discharge tray 4 sides 15.And; The moment that detects the rear end of sheet material P from alignment sensor S2 begins; The drive pulse number of times of counting drive motor MOT reaches moment of predetermined pulse number of times (pulse B) in this count value, makes drive motor MOT switch to inversion driving (ST16～ST18) from just changeing to drive.Thus, the upset exit roller switches to counter-rotating to 15 from just changeing, and sheet material P turns back on upset route 21.The pulse number of said regulation (pulse B) be and from alignment sensor S2 to tertiary membrane parts M3 and the upset exit roller to the drive pulse number of times of the cooresponding drive motor MOT of distance of the assigned position 15.
Via the upset exit roller the 15 sheet material P that turn back are transferred 13 to reading preliminary roller along upset route 21.And, when the front end of sheet material P is detected by alignment sensor S2 again, and the alignment actions 2 that execution is described below (ST19～ST20).
In alignment actions 2, making magnetic clutch CL2 is OFF, stops to read preliminary roller to 13 rotation (ST41).Simultaneously, the counting of the drive pulse number of times of beginning drive motor MOT makes pulse number (pulse A) that drive motor MOT inversion driving reaches regulation up to pulse number (ST42).Thus, the front end of sheet material P docks with reading the pressure contact portion n1 of preliminary roller to 13, forms to quasi loop the front end (with reference to Fig. 5-6) of adjustment sheet material P among the space S P2 through aiming at second.When the pulse number of drive motor MOT reached the pulse number (pulse A) of regulation, making drive motor MOT switch to from inversion driving just changeed driving (ST43).
When carrying out said alignment actions 2, making magnetic clutch CL2 is ON (ST21).Thus, read preliminary roller and just changeing driving to 13, sheet material P upset also is transported on the platen 5, and the back side of sheet material P is read.Then, the rear end of accomplishing the sheet material P that reads at the back side is detected by alignment sensor S2, during with predetermined pulse number of times (pulse B) feeding sheets P, makes drive motor MOT switch to counter-rotating (ST22～ST24) from just changeing.Then, the upset exit roller switches to counter-rotating to 15 from just changeing.And through switching the upset exit roller to 15 hand of rotation, sheet material P turns back on upset route 21 once more, is transferred (with reference to Fig. 7) to reading preliminary roller to 13 along this upset route 21.And, when alignment sensor S2 detects the front end of sheet material P, carry out alignment actions 2 (ST25～ST26) once more.
After alignment actions 2 was carried out, making magnetic clutch CL2 was ON (ST27).Thus, read preliminary roller 13 rotations are driven, sheet material P overturns and is transferred to platen 5.And sheet material P is through after the platen 5, via read preliminary roller to 13, read the back roller to 14 and the upset exit roller carried to discharge tray 4 15.In addition, the action of ST25～27 is the actions that are used for putting in order the page number of the sheet material P that is housed in discharge tray 4 order.Thus, do not carry out here through platen 5 sheet material P read processing.And, be the arrangement page number, when the rear end of the sheet material P that has overturn was detected by alignment sensor S2, making magnetic clutch CL1 again was ON, begins the paper supply (ST28, ST12) of next sheet material P.
In addition, in this embodiment, have first to the 3rd aligning space, but also can omit the 3rd of upset route 21 and aim at space S P3, can aim at space S P2 via second and correct the crooked of sheet material fully according to sheet material.
As stated, in this embodiment, the reading of the surface through will carrying out sheet material carried and the aligning space of reading when carrying at the back side of sheet material is separately positioned near the upstream side of reading part, can before reading part, implement the correcting deflection of sheet material.Thus, can further improve the precision that reads processing of sheet material.In addition owing to sheet material is respectively aimed at space guiding to said through membrane element, so can carry out the guiding of sheet material swimmingly, and can produce sleekly the sheet material respectively aimed in the space to quasi loop.
In addition; The first aligning space and the second aligning space by outside spigot surface, according to the conveying of sheet material can flexure deformation first guiding parts and second guiding parts form; Thereby can not bring inadequate power, can form along said and respectively aim at the correct of space quasi loop to sheet material.
