Description
Technical field
The present invention relates to image processing systems such as duplicator, facsimile unit and chopping machine, relate to the paper transport device that the recording medium with the paper shape (hereinafter referred to as paper) that is provided on the above-mentioned image processing system is transported to image forming part.
Background technology
In ink-jet recording apparatus, paper is transported to the paper transport device of the mechanics that prints, use automatic paper feeding (ASF) mode that has and sheet feed cassette mode conveyance of sheets as a field of image processing system.The ASF mode is that the paper that directly is accommodated in the recording device main body is sent, and the sheet feed cassette mode is to make it to be installed on the recording device main body under the state of having taken in paper or unloading down from it.In addition, also practicability of the paper transport device that recently these ASF modes and sheet feed cassette mode is combined.Particularly large-scale chopping machine or duplicator divide the paper transport device of multilayer ground configuration same structure and the machine practicability of conveyance of sheets selectively.
About above-mentioned sheet feed cassette mode, the someone has proposed on main box to insert secondary box, has carried the scheme (Japanese patent gazette spy opens clear 61-188335 number) of the paper of variety classes size selectively.In addition, the somebody has proposed organization plan (Japanese patent gazette spy opens flat 6-40582 number) that secondary box is overlapped on the main box, it can be carried by different separately paper feed rollers.Under the situation with such major-minor box, most forms are to place common paper such as A4 size in main box, place for example thicker L version photo log sheet or postcard wait and use in secondary box.
But the kind of paper also is varied recently, for example, even chopping machine also can print corresponding to various paper.Wherein because ink jet printer also is noncontact to be printed, less to the situation that the kind of paper will limit, so the size of paper or kind are all increasing always, in order to comply with the trend of this increase, the replacing frequency that loads paper is also very big.In addition, even the low various chopping machines of price comparison also are required structurally can carry a plurality of paper transport devices, so that can adapt to the paper of variety classes size.
Because paper type is a lot, the action that paper is shown in course of conveying also is various.For example, have the paper of the ink-jet of liquid ink impression layer, show following action with postcard, glossiness postcard, card and name card size.When printing, after just spraying into liquid ink, though according to the paper difference, the once serious warpage that also has and curl (curl), after after a while, this rolled state reduces, and returns to original shape with regard to disappearance soon.The A4 paper that size is bigger than postcard etc. since paper from great, so size is more little can not to produce bigger curling more.If produced and curled, then when discharging the 2nd follow-up paper, the 1st paper will going ahead of the rest of this follow-up paper released together sometimes, or the go ahead of the rest surface of finishing record of paper of follow-up paper friction.In order to prevent this improper situation, even small-sized chopping machine had also been guaranteed the drop till the loading surface from the paper discharge orifice to discharge tray fully in the past.But, design, make discharge tray to be set in the device of fixed sturcture as the fixed position making the position that such drop is enough big, if be discharged from the size and the kind of the paper that comes or can load the viewpoint of the so high bulk property of more paper in proper alignment from adaptation as far as possible, then most cases is ill-considered.
Purpose for the discharge tray of realizing having high bulk property, someone has proposed discharge tray location is not fixed on from the paper discharge orifice has on the position of drop, is device design plan (Japanese patent gazette spy open flat 5-17064 number) that so-called above-below direction move by driving means to world direction and make discharge tray.In addition, the somebody has proposed such organization plan: conventional cut paper is loaded on the main floor of discharge tray, and envelope etc. is loaded on the parabasal plate on the part that is set at this main floor to improve bulk property (Japanese patent gazette spy opens 2002-87682 number).In said structure, support main floor with spring from the below, this main floor makes the spring compression corresponding to paper weight and sinks.Because parabasal plate is that small-sized envelope is used, so the elastic force of the spring that this parabasal plate is used is bigger than the spring of main floor.Therefore, if envelope then when having loaded the number of Duoing than conventional cut paper, at first comes compression spring by parabasal plate.Like this,, also can load more number, improve bulk property even be under the situation of small-sized envelope of several times of conventional cut paper at paper sheet thickness.
But, the problem below in existing technology, existing respectively.In the Japanese patent gazette spy opens clear 61-188335 number disclosed paper transport device, exist and to switch box and under the situation of using main box, all must pull out the trouble that secondary box is taken care of etc. at every turn in the manually operated mode.
In addition, open in the disclosed paper transport device of flat 6-40582 the Japanese patent gazette spy, what exist for printer main body paper transport device occupies very big and so on the problem in space.
In addition, open the disclosed loading pallet of 2002-87682 for the Japanese patent gazette spy, if in order to guarantee the drop till the loading surface from the paper discharge orifice to discharge tray fully corresponding to different types of paper, then only because work will make device volume increase very greatly like this.In addition, be equipped with the driver train that makes discharge tray moving up and down again, increasing drive motor and drive transmission device, just making device maximization and complicated more.
In addition, in the Japanese patent gazette spy drives flat 5-17064 number disclosed image processing system, the upper-lower position that elastic force by making spring and paper loading balanced are determined main floor and parabasal plate.Therefore, if the spring performance of each spring of main floor and parabasal plate has deviation, then can not guarantee the paper loading amount on main floor and the parabasal plate.In addition, rely on a kind of elastic force not adapt with the variation of paper type.
Summary of the invention
The objective of the invention is to, provide a kind of user of alleviating to carry out the work capacity of box when switching, device volume is reduced but also can improve the paper transport device and the image processing system of the bulk property of discharging paper etc.
The present invention also aims to provide a kind of following paper transport device, it has the paper incorporating section of boxlike, the paper incorporating section of above-mentioned boxlike removes can being installed on the image processing system main body or from above-mentioned image processing system under the state of having taken in paper, in above-mentioned paper transport device, above-mentioned paper incorporating section has the main incorporating section and the secondary incorporating section of the paper of taking in the variety classes size simultaneously, being provided with on the cover part of the above-mentioned main incorporating section of switch can be to the above-mentioned secondary incorporating section that sheet transport direction moves, above-mentioned paper transport device can be from above-mentioned secondary incorporating section conveyance of sheets under the state that is installed on the above-mentioned image processing system main body.

Paper supply path (paper transportation path) when Fig. 3 represents to print.Paper feed roller 12 is to be used for picking up the parts that paper S carries one by one from sheet feed cassette 100.The paper S that extracts out successively from sheet feed cassette 100 is carried by conveying roller 13,15,17 on transport path.LF roller 19 and pinch roll the 14,16,18, the 20th are used for paper S is clipped in the parts of carrying between these rollers.The paper S that is transported to LF roller 19 is supported on the platen 27, and is transported to the position that predetermined distance is only arranged from header record 23.Balladeur train and its synchronously carry out reciprocating action, form image by header record 23 on paper S, print.Exit roller 21 is discharged and is printed the paper S that is over, and fixture block 22 works to compress paper S.Printing the paper S that finishes carries along the direction of arrow among the figure.Discharge tray 25 can be flexible according to the size that is discharged from the paper S that comes, and loads and accumulation paper S.
Fig. 4 represents sheet feed cassette 100 with the form of monomer.Sheet feed cassette 100 has main box (main incorporating section) 101, loads the paper S1 of large-sizes such as conventional cut paper A4 here, sends paper S1 by the paper supply direction shown in the arrow A.Be provided with pressing plate 104 in this main box 101, it is used for upwards pushing away a repeated paper S who has been loaded from the below, makes the paper S of paper feed roller 12 (Fig. 3) crimping upper.In addition, have the most lid 102 that covers main box 101, as shown in Figure 5, this lid 102 can rotate to the direction of opening main box 101 by means of left and right sides bearing pin 102a.Secondary box (secondary incorporating section) 103 is assembled and taken in inside at the lid of opening like this 102.Stowing dimensions is than the little paper of paper S1 that is loaded in the main box 101 in secondary box 103, and for example postcard or L open paper S2 such as size.Replenishing of paper S2 can be carried out under state shown in Figure 4.When replenishing, paper S2 is adjusted by end guide rail 107 and side rails 108 and by proper alignment.
As shown in Figure 5, lid 102 can be that rotating fulcrum upwards erects up to the state that is approximately perpendicular to main box 101 with bearing pin 102a, can unload down from main box 101 together with each bearing pin 102a under the posture unmodified state that erects that keeps up.Under the state that lid is unloaded, can in main box 101, replenish paper S1.By connecting with end guide rail 105 and side rails 106, the edge of above-mentioned paper S1 is positioned by the paper S1 that replenishes, and thus, paper S1 is by proper alignment.If the state (with reference to Fig. 4, Fig. 6, Fig. 7) that lid 102 is become closing, the pawl 102b (Fig. 4) that then is arranged on the lid leading section will be fastened on main box 101 1 sides, and lid 102 is locked.
Be entrenched in 2 the guide groove 102c (Fig. 7) that are arranged on the lid 102 by the guide finger 113a and the axis of guide 109 that makes secondary box 103 1 sides, the secondary box 103 that has been assembled in the lid 102 is carried out guiding, thereby can move to sheet transport direction.On secondary box 102, be provided with phasing gears 110, do not crook so that secondary box 102 does not produce in moving.That is, the above-mentioned axis of guide 109 that can rotate freely is set on secondary box 102, the two ends of this axis of guide 109 are entrenched in the guide groove 102c.Therefore, make the tooth bar 102d on axle two ends same-phase phasing gears 110 that rotates and the top cover that is arranged on lid 102 be meshed.
In addition, the side position (edge) that also has with paper S2 is the paper supply guide rail 113 that benchmark positions the paper S2 that are loaded in the secondary box 103, and the thin parts of this paper supply guide rail 113 for making by sheet metal processing etc. are fixed on the secondary box 103.Paper S2 relies on benchmark one side by side rails 108 and end guide rail 107.Connecting about the top board of paper supply guide rail 113, it is covered with paper S2, produces warpage to prevent paper S2.But for the paper (is card sizes at this) that easily loads smaller szie, leaning on a side opening of benchmark is broad.In addition, front end is by stop bar 112 alignment.Stop bar 112 is can be along the vertical direction movable, can rely on spring to float from secondary box 103 paper supplies the time, so that back out from paper S2.In addition, rely on to be covered with by stop bar 112 and to be supported in baffle plate 111 on the lid 102 with free rotation mode, even under the situation that the posture of lid 102 has taken place to change, the paper S2 in the secondary box 102 can unexpectedly not fly out yet.
In addition, as indicated in Fig. 6 and Fig. 8, be provided with tooth bar 103b in the side of secondary box 103, this this tooth bar 103b be with the medial surface that is arranged on lid 102 on S. A. on connection gear (drive disk assembly) 114 be meshed.Sheet feed cassette 100 is being inserted into when having carried out installation in the printer main body 1, this transmission gear 121 of waiting on connecting gear 114 and being set at printer main body 1 one sides is meshed.Rotary power is delivered to transmission gear 121 from the main body drive source, makes this rotary power act on secondary box 103 by means of connecting gear 114 and tooth bar 103b, and secondary box 103 is moved as straight line to sheet transport direction.In addition, stop component (Lock Part) 115 is fastened on the connection gear 114 or is separated with it, when sheet feed cassette is installed, above-mentioned stop component 115 is from it and connect fastening state between the gear 114 and break away from and unlock, this connection gear 114 can be rotated, when taking out sheet feed cassette, as shown in Figure 6, connect on the gear 114 by being fastened on, will connect the spin locking of gear 114.By in this wise connection gear 114 being rotated locking or unlocking, prevented that secondary box 103 from unexpectedly moving.
In addition, in Fig. 6, be provided with the test rod 116 that detects secondary box 103, whether be in position of readiness (dead position) in order to detect secondary box 103, test rod 116 be installed in can with the position of the axis of guide 109 butts of secondary box 103 on.If secondary box 103 moves and breaks away from the axis of guide 109 to the direction of conveyance of sheets, then secondary box test rod 116 rotates, and the height of test section 116a changes.Detect by dead position sensor 130 and to have or not secondary box 103, control the dead position of secondary box 103 across the intermediate examination and measurement bar 131 (with reference to Fig. 9) that is set at printer main body 1 one sides.
Transmission gear row when Fig. 8 has represented to install sheet feed cassette.Rotation is driven the drive source of the paper feeding motor 122 of mobile paper feed roller 12 as the moving sets box.That is, the rotary power of paper feeding motor 122 is passed to the transmission gear row,, make secondary box 103 move from connecting gear 114 through tooth bar 10b.Paper feeding motor 122 drives paper feed roller 12 and PF roller owing to unclamp the paper supply trigger when retrograde rotation when being rotated in the forward, so only utilize to be rotated in the forward secondary box 103 is moved.Configuration midway at transmission gear row is used to switch from the hand of rotation of paper feeding motor 122 or the switching mechanism 125 that cuts off rotation, the rotation from paper supply motor 122 can be set to be rotated in the forward, retrograde rotation, to cut off any one state among this three.In addition, on the close locational gear of gear row afterbody, inserted the clutch gear 124 that clamps friction clutch.Under the state that sheet feed cassette 100 is installed on the printer main body 1, because switching mechanism 125 is " cut-out " state, so paper feeding motor 122 can unrestrictedly move.What will clarify once more here is, by sheet feed cassette 100 being inserted on the printer main body 1 and with the installation action interlock, being fastened on to connect makes the stop component 115 that is locking rotation leave from connecting gear 114 on the gear 114, become disengaged position, unlock thus, connection gear 114 can be rotated freely.
(supplying with the action of paper S1 from main box 101)
If the state of sheet feed cassette Fig. 9 before is installed from expression sheet feed cassette 100 is inserted in the printer main body 1, then pressing plate bar 128 descends, and on the phase place that is in the state that has compressed not shown spring, pressing plate cam 127 stops.Owing on test rod 131, do not detect thing, so the dead position sensor 130 of secondary box 103 detects OFF.
If sheet feed cassette 100 is inserted in the printer main body 1 along track 132, then the protuberance 129 of the abutting part 115a of stop component 115 and printer main body 1 connects, and breaks away to connect gear 114, connects gear 114 and is disengaged locking, can be rotated, secondary box 103 becomes movably state.If deeper insert sheet feed cassette 100, then connect gear 114 and link to each other with transmission gear 121, can drive (with reference to Fig. 8) by the drive source of main body.In addition, the bearing surface 116a butt of test rod 131 and secondary box test rod 116 detects the position of secondary box 103, becomes the state of ON.At this, sheet feed cassette 100 is positioned when running into paper supply unit 2, becomes the state that the installation in printer main body 1 finishes at this position sheet feed cassette 100.
Figure 10 represents the installing condition of this sheet feed cassette.The pressing plate 104 of sheet feed cassette 100 is stuck close in the groove that is set on the pressing plate bar 128, and pressing plate bar 128 and pressing plate 104 can move integratedly when mounted.In Figure 11, represent the paper supply path with arrow.If paper feeding motor 122 rotations under the state that sheet feed cassette 100 has been installed, paper supply action beginning, then paper feed roller 12 rotations, pressing plate bar 128 will rise with pressing plate cam 127.The pressing plate 104 of the sheet feed cassette 100 that engages with pressing plate bar 128 makes the paper S1 crimping paper feed roller 12 that is loaded on the pressing plate 104 to rising.Under this state, paper S1 relies on the rotation of paper feed roller 12 to be transferred.At this moment, separate, only be transferred one by separation device.Then, paper S1 is carried by conveying roller 13.Because paper feed roller 12 rotates a circle and just stops, separation device is backed out, so paper feed roller 12 can not become load, but paper sheet delivery is proceeded.At this moment, the state of sheet feed cassette 100 turns back to the state of Figure 10.After this, paper S1 arrives LF roller 19, is transported to the front of header record 23 always, finishes the paper supply action.After this, can make header record 23 and LF roller 19 synchronous, print simultaneously according to print data.Print once finishing to discharge paper S1, a series of release.
(from the action of secondary box 103 conveyance of sheets S2)
In order to supply with paper S2, must carry out blocked operation from secondary box 103.As shown in figure 10, under the state that sheet feed cassette 100 is installed, secondary box 103 is in sheet feed cassette 100 from paper supply direction position farthest.In this stage, the dead position sensor 130 that is set on the printer main body 1 detects ON, detects secondary box 103 and is in normal position.If the switching mechanism 125 in this state lower gear transmission switches, make from the rotation of paper feeding motor 122 by being rotated in the forward transmission, drive paper feeding motor 122 rotations, then shown in the arrow A among Fig. 8 like that, each connecting portion moves, and connects gear 114 and rotates along the direction shown in the arrow A.By with connect the tooth bar 103b that gear 114 meshing secondary box 103 moved to paper supply locality (arrow A).If secondary box 103 begins to move from the state of Figure 11, then secondary box test rod 116 leaves the axis of guide 109 of secondary box 103 and rotates, and dead position sensor 130 is shown as OFF.If motor drives, the axis of guide 109 of then secondary box 103 and guide finger 103a advance along the guide groove 102c of lid 102.At this moment, Yi Bian because same-phase ground is set at phasing gears 110 one side at the two ends of the axis of guide 109 is meshed with tooth bar 102d on being set at lid 102 and advances, so, will move smoothly and do not crook.If continue to drive, a little advances on one side the spigot surface 101b of stop bar 112 1 edge master's boxes 101 of then secondary box 103 front ends descends, and is last, is inserted in the hole 117 of PF pedestal, and secondary box 103 collides the paper supply position.
Figure 12 vice box 103 has moved to the state of paper supply position.After the front end crash of secondary box 103, do not have overload ground from the rotation of paper feeding motor 122 by the clutch gear 124 of transmission gear row and stop.After this, switching mechanism 125 turns back to the state of the driving that disconnects paper feeding motor 122 and transmission gear row.In addition, if the secondary box 103 that is maintained in the lid 102 moves to the paper supply position at position of readiness, then the guide finger 103a of front end one side will be disengaged from the guiding state, only by the axis of guide 109 guiding, so, be that the center only has front end one side of secondary box 103 to become the state that can freely rotate with the axis of guide 109.
So just can supply with paper S2 from secondary box 103.Figure 13 represents to supply with from secondary box 103 state of paper S2.As if the paper supply action of carrying out pressing plate 104 under the state that moves to the paper supply position at secondary box 103, then as shown in the figure, the pressing plate 104 of main box 101 is to rising, and secondary box 103 is that rotate at the center with the axis of guide 109, and its front end one side rises higherly, is urged on paper feed roller 12.At this moment, the stop bar of secondary box 103 112 so upwards do not boosted, but is in the position of former height because its front end 112a is inserted in the hole 117 of PF pedestal on main body, and therefore, the wall of the paper supply side of paper S2 has not just had.Like this, the paper S2 that is loaded on the secondary box 103 can be carried out conveying equally with the paper S1 of main box 101, and can print.
Finish the action that secondary box 103 is retreated if print.If switching mechanism 125 switches to the rotation of paper feeding motor 122 retrograde rotation and makes paper feeding motor 122 rotations, then each connecting portion moves along the direction shown in the arrow B among Fig. 8.Connect gear 114 along the rotation of the direction shown in the arrow B, secondary box 103 is moved to position of readiness (arrow B).If secondary box 103 retreats, the front end of then secondary box test rod rides on the axis of guide 109 and rotates, and by means of test rod 131, dead position sensor 130 is shown as ON, stops at position of readiness shown in Figure 10.After this, switching mechanism 125 cuts off from the drive transmitting of paper feeding motor 122 to the transmission gear row, turns back to initial condition.
As mentioned above, secondary box 103 can move conveyance of sheets S2 between position of readiness and paper supply position.In addition, when printer main body 1 has taken out sheet feed cassette 100, because when the gear row that drive were thrown off, the connection gear 114 of sheet feed cassette 100 was ended by stop component 115 cards and can not rotate, so secondary box 103 can unexpectedly not move.That is, even under the situation that lid 102 is started by the user, or under the situation of the sheet feed cassette 100 that has taken out with posture placement arbitrarily, the position of secondary box 103 can not misplace yet.Therefore, when sheet feed cassette 100 is installed, can omit the action that the position of secondary box 103 is turned back to one by one position of readiness (dead position).
In addition, in the present embodiment, though make the spin locking that connects gear 114, to stop moving of secondary box 103, also can be structurally for can be not by connecting gear 114 but directly lock fixed joint box 103, maybe can unlock.In addition, as drive source, be not limited to utilize paper feeding motor 122, also can utilize other motor such as CR, LF, in addition, promptly use manually to drive, effect too.
(the 2nd embodiment)
Figure 14 represents also to can be described as the 2nd embodiment of the application examples of above-mentioned the 1st embodiment.In the structure shown in the 1st embodiment, be that lid 102 is rotated around bearing pin 102a, the structure of unloading down from the last standing position gesture that is approximately perpendicular to main box 101.To this, in this 2nd embodiment, the structure of its structure for mentioning lid 102 vertically upward and make it to unload down with remaining unchanged from the state that is stopping up main box 101.Thus, the superimposed configuration on above-below direction of main box 101 and secondary box 103, lid 102 is positioned on the main box 101 by position pin 101d, when secondary box 103 is moved, cap body and outage.Therefore, in this 2nd embodiment,, can improve the operation comfort feature when in main box 101, replenishing paper S1 simply with respect to main box 101 dismounting lids 102 when printer main body 1 has taken out sheet feed cassette 100.
In the above-mentioned the 1st and the 2nd embodiment, have following effect:
(1) can not change sheet feed cassette 100 as before, save the trouble of when supplying with the paper of variety classes size, changing box, only just can replenish paper simply by dismounting.
(2) after printer main body 1 has taken out sheet feed cassette 100 and since main box 101 not only can with lid open-close and but also can unload down, so be easy to replenish paper to main box 101 and secondary box 103.
(3) since will be used for from the drive source of printer main body 1 accept power, transmission device that secondary box 103 is moved is arranged on lid 102, become reciprocating secondary box 103 is advanced or the mechanism of backward movement to the direction of conveyance of sheets so can constitute power-supply change-over with positive and negative rotation simply, and transmission reliably.
(4) on lid 102, be provided with the lockout mechanism that prevents that when having taken out sheet feed cassette 100 secondary box 103 from unexpectedly moving.Therefore, when carrying out to main box 101 that paper replenishes or changing, even moving to the direction of uncover 102, secondary box 103 also can be just moving everywhere, the initial position that can keep secondary box 103 thus reliably.
