Punching apparatus

The application requires the spy of on June 22nd, 2006 in Japanese publication to be willing to 2006-173066 number and the right of priority of 2006-173067 patented claim.The full content of this application is integrated with among the application, as a reference.

Technical field

The present invention relates to a kind of punching apparatus, it is configured in paper sheet delivery that image is formed back (print back) to the transport path of the " loaded " position of discharge portion midway, is used to carry out the paper postprocessing working procedures.

Background technology

Image print to conveyance of sheets in the existing image processing system is handled, utilize developer (toner) will be formed at electrostatic latent image visual imageization on the electrostatic latent image carrier (photosensitive drums), in transfer printing process so that the consistent sequential conveyance of sheets of front end of the image information on the front end of paper and the photosensitive drums, thereby by transfer printing portion image information is transferred on the paper.

In recent years, be accompanied by the high speed of the print processing speed of exploitation that coloured image forms device, image processing system, in transfer printing process, require the high printing transferring method of efficient.Now, mode as more use in the transfer printing process, there are modes such as " corona charging device ", " roller transfer ", " brush transfer printing ", " band transfer printing ", all be to use following method in any one mode: in the transfer electric field (about about 1～3kV) that applies on each parts with the charged polarity opposed polarity of developer (toner), the toner image that electricity is adsorbed onto photosensitive drum surface is transferred on the paper.Applied the paper of this transfer electric field, by the toner image on the photosensitive drums being transferred to electric field on the paper and charged.

In addition, conveyance of sheets by with the friction of a plurality of conveying rollers, paper guide etc. of configuration from the sheet feed section to the discharge portion, and frictional electrification, the paper that print processing finishes to discharge the back approximately has the static of 1～2kV.And, when many on the paper of electrostatic charging is discharged to discharge dish portion like this, between paper, produces and repel electric field, may cause the bulk property of discharge dish portion bad.

Therefore, as the scheme that addresses this is that, proposed near distributing roller configuration and removed brush (for example with reference to Japanese patent laid-open 02-23384 communique (hereinafter referred to as " patent documentation 1 ")) by what the electric conductivity brush constituted.

Recently, for being transported to the transfer printing portion that carries out transfer printing process effectively, the paper that will carry adopt the device of " band transfer printing " mode of having used transfer belt to become many.In band transfer printing mode, build bridge in the endless belt that will have predetermined resistance with a plurality of rollers, between a roller in the roller of building bridge or the roller of building bridge, constitutes the transfer area that is called transfer nip with respect to photosensitive drums.

In this band transfer printing mode of carrying out transfer printing process, to compare with modes such as existing " corona charging device ", " roller transfer ", " brush transfer printings ", the electric field that is applied on the transfer belt becomes many.That is, need following electric field: make conveyance of sheets be adsorbed on " absorption electric field " on the transfer belt; Indispensable in the transfer printing process " transfer electric field "; With for will adsorb/paper after the transfer printing successfully is transported to subsequent processing and " peeling off electric field " of being used for paper is peeled off from transfer belt etc.

So, in transfer printing process, adopted in the image processing system of band transfer printing mode, in transfer printing process, be subjected to above-mentioned a plurality of electric field effects, and the conveying roller from transport path etc. is subjected to frictional electrification.In addition, when print processing be not only need transport path by but in twice of needs or the print processing pattern of passing through (colour print tupe) more than it, can be subjected to above-mentioned various electric field effects by the number of times of transfer printing process and transport path.

The result that carried charge when table 1 is illustrated in so various print processing patterns conveyance of sheets is through with the print processing operation is measured.

Table 1 (the electrostatic belt electric weight of conveyance of sheets)

	Paper carried charge (kV/1 opens) (paper type: A4) during discharge
		Game of shuttlecocks seal (duplex printing) (gradation of drop-out colour 0%)	1.0～1.5
Monochromatic print (duplex printing)	2.0～3.5
		Colour print (duplex printing)	4.0～6.5

As known from Table 1, compare, in colour print, accumulated a large amount of static of the degree that can't compare in the paper with game of shuttlecocks seal and monochromatic the printing.

Paper to discharging with above-mentioned state increases as lower device in nearest image processing system: as the multifunction of device, the aftertreatment portion of the postprocessing working procedures that prints paper is set gradually.In postprocessing working procedures, staple together and handle and saddle stitchings processing such as perforation processing, bookbinding, filing processing etc.

Wherein, to as above electrostatic charging paper in postprocessing working procedures, bore a hole when handling, the paper after the perforation produces the perforation bits.In this case, when static electrification is considered not in perforation to be worth doing, because deadweight of perforation bits etc. and drop in the accommodating container of perforation bits naturally and pile up naturally, but the perforation that has static considers to be worth doing and can not drop to naturally in the accommodating container, and meeting is adsorbed on the container wall etc. because of static.

Figure 17 represents the state of this moment.As shown in figure 17, be disposed at being full of on the detecting sensor 102 of container wall etc., then can frequently produce following flase drop and survey: though the amount of taking in of accommodating container 63 and underfill are full of detecting sensor 102 and are detected as and are full of if perforation bits 130 are adsorbed onto.In addition, be adsorbed on 130 contacts of perforation bits of container wall, thereby produce into piece phenomenon (arch formation), might in accommodating container 63, produce space 150.Can produce following problem in this case: owing to pile up thereon perforation bits 130, cause being full of sensor 102 before and be detected as and be full of in the suitable amount of taking in (being full of).In addition, may produce following problem when taking out the insertion accommodating container: the perforation bits 130 that have static can disperse to external container, and are adsorbed onto device inside.

Therefore the technology (for example opening 2003-232671 communique (hereinafter referred to as " patent documentation 3 ") etc. with reference to Japanese patent laid-open 11-255417 communique (hereinafter referred to as " patent documentation 2 "), spy) that is used to address this is that has been proposed.

In patent documentation 2, disclose:, make the perforation bits of mountain shape smooth by perforation bits vibrating device vibration perforation bits accommodating container.In addition, in patent documentation 3, disclose: the checkout equipment that has the fastening that can support the perforation bits charging appliance that receives the perforation bits up or down and the down position of the perforation bits charging appliance that descends along with the increase of the Weight Loaded of perforation bits is detected, when perforation bits charging appliance drops to preposition, detect in perforation bits charging appliance, being full of the perforation bits.

Above-mentioned patent documentation 1,2 disclosed technology, image processing system be low-speed machine, print processing pattern for the frictional electrification amount of conveyance of sheets such as monochromatic printing more after a little while, be otherwise effective technique.That is, as described in above-mentioned technology, the countermeasure when being 1～2kV left and right sides as the frictional electrification amount can be expected corresponding effects.

But, nearest image processing system, high speed and when adopting band transfer printing mode in transfer printing process as mentioned above becomes, as shown in table 1, the electrostatic belt electric weight of paper increases, therefore even as vibration perforation bits accommodating container as described in the patent documentation 2, the perforation bits that are adsorbed on container wall etc. can not fall fully.

In addition, according to patent documentation 1 described technology, dispose except that brush in the downstream of distributing roller, the static of paper is removed when therefore being discharged to paper disc.But, when having appended postprocessing working procedures, still there are the following problems: owing to handle the strong shearing force that produces by perforation with the perforation of tapping machine when perforation is handled, the perforation bits produce frictional electrification, therefore the perforation bits are adsorbed on the container wall etc., are full of detecting sensor generation flase drop and survey.

In addition,, be adsorbed on even perforation bits have static on the container wall etc.,, therefore can eliminate the flase drop that whether is full of and survey because what detect in fact is the weight of perforation bits charging appliance (perforation bits accommodating container) self according to patent documentation 3 described technology.But, be different from the existing detecting sensor that is full of, need the new detecting sensor etc. that making portion of perforation bits charging appliance mechanism moving up and down, detecting the decline of perforation bits charging appliance that is provided with, the structure of the treatment process that causes being used to boring a hole becomes complicated, and component costs rises for this reason.In addition, because structure becomes complicated, thereby there is the further problem of miniaturization of device.

In the unit 70 of stapling together, when printing, request exists under the situation of the request handled of stapling together, by 71 pairs in the portion of mechanism that the staples together recording chart of the predetermined number that loads on the platform 72 processing of stapling together of stapling together as print conditions.At this moment, the processing of on the position of determining according to print paper size and the required position of stapling together, stapling together.The required position of stapling together is the position of stapling together and handling that the user needs, for example two positions of the upper left bight of recording chart position or left part.

The portion of mechanism 71 that staples together is configured in the below of distributing roller 54, with staple the rearward end of the recording chart that loads on the platform 72 of stapling together is bound.The portion of mechanism 71 that staples together constitutes and can move back and forth along paper width direction, the processing of can stapling together on the above-mentioned position of determining according to print paper size and the required position of stapling together.Staple together when handling by the unit 70 of stapling together, the portion of mechanism 71 that staples together is moved on the position corresponding with the above-mentioned position of determining according to print paper size and the required position of stapling together.

The platform 72 of stapling together loads the recording chart of discharging from distributing roller 54, is to be stapled together by the portion of mechanism 71 that staples together to handle the treatment bench of usefulness.The platform 72 of stapling together is configured the sheet transport direction downstream upward obliquely.The recording chart of discharging from distributing roller 54 is being stapled together when handling, because of deadweight is tilted to the landing of sheet transport direction upstream side along the platform 72 of stapling together.On the other hand, do not staple together when handling, recording chart is as described below to be discharged to paper disc 8 from exit roller 74.

Adjust plate 73, dispose relatively in the both sides on the direction of paper width direction of the upper surface of platform 72 of stapling together (discharging the face of recording chart).A pair of adjustment plate 73 is set to and can moves back and forth along paper width direction.And, in the unit 70 of stapling together, staple together when handling, make and adjust plate 73 and move, thereby carry out the location of paper width direction being discharged to every recording chart on the platform 72 of stapling together along paper width direction.At this moment, with corresponding, move and adjust plate 73 according to print paper size, the movable width promptly determined according to the size of the recording chart of carrying.

Moving back and forth of a pair of adjustment plate 73 for example can be undertaken by rack-and pinion gear mechanism.Specifically, adjust rack member that plate 73 is connected and adjust the rack member that plate 73 is connected, the interval that the interval is scheduled to and opposite each other with another with one.In addition, dispose pinion wheel between two rack member, itself and two rack member mesh respectively.Wherein, two rack member are set to and can move back and forth along paper width direction, and are relative with it, and pinion wheel is set to and can not moves.And, transmit power rotary pinion, thereby a pair of adjustment plate 73 moved along paper width direction with being mutually symmetrical from drive source.Thus, can be discharged to the location of recording chart on paper width direction on the platform 72 of stapling together.

(exit roller 74)

Exit roller 74 in the downstream of the sheet transport direction of the platform 72 of stapling together, disposes a pair ofly up and down in the mode towards row's paper disc 8, the recording chart on the platform 72 of stapling together is discharged on the paper disc 8.Exit roller 74 is as described below, also is also used as recording chart is distinguished the skew roller (shifter roller) that is discharged to paper disc 8.Exit roller 74 all is provided with as driven roller up and down.That is, exit roller 74 all is connected with drive source up and down.

In addition, be set to can be from connecing (separate contact) for exit roller 74 up and down, and being set to (this moment for upside) exit roller 74 can move up at upper and lower with respect to another (this moment for downside) exit roller 74.When recording chart was discharged to paper disc 8, exit roller 74 was the state of mutual crimping about making, and on the other hand, when recording chart being stapled together processing, making up and down, exit roller 74 is state disconnected from each other.Position when in addition, the initial position of exit roller 74 is mutual crimping up and down.

By can exit roller 74 up and down being set, has following advantage from ground connection.Staple together when handling, exit roller 74 is released state about making, and the leading section that makes the recording chart that is transported to the platform 72 of stapling together is from outstanding between the exit roller 74 up and down.Thereby can shorten the platform 72 of stapling together in the length on sheet transport direction, can make unit 70 compactnesses of stapling together.And after the processing of stapling together, exit roller 74 is crimped status about making, and the recording chart bundle of stapling together after handling is discharged to paper disc 8.Thereby need not to be provided with in addition the recording chart bundle after handling of stapling together is discharged to the mechanism of paper portion, for example releases the mechanism of recording chart bundle.

At this, the migration processing of being undertaken by exit roller 74 is described.In this example, by carrying out migration processing, distinguish recording chart and it is discharged to paper disc 8 by 74 pairs of recording charts of exit roller.

Migration processing is following processing: from a plurality of positions recording chart is discharged to paper disc 8 along paper width direction, thereby the drain position of the recording chart on the row's of making paper disc 8 is departing from the direction of paper width direction, carries out the differentiation of recording chart.This migration processing for example can reciprocatingly be arranged on exit roller 74 up and down on the direction of principal axis (along the direction of paper width direction).Specifically, clamping under the state of recording chart, exit roller 74 is up and down moved on direction of principal axis with exit roller 74 up and down.Thereby the recording chart of being clamped by exit roller 74 up and down moves along paper width direction.When being discharged to recording chart on the paper disc 8 in this position, the drain position of the recording chart on can the row's of making paper disc 8 is departing from the direction of paper width direction.So, for example can distinguish, first part last page and second part first page are not discharged on the same position of row's paper disc 8 according to the umber of recording chart.In addition, by exit roller 74 is also used as the skew roller, can realize the minimizing of components number, the minimizing of cost etc.In addition, after discharging recording chart, exit roller 74 up and down turns back to initial position.

And, as mentioned above exit roller 74 up and down is set to and can has following advantage from connecing.Exit roller was also used as under the situation that is offset roller in the past, stapled together when handling, can't carry out migration processing.That is, exit roller is not can be from connecing, so the offset functions of exit roller is only corresponding with the recording chart handling of stapling together, and can not be corresponding with the recording chart bundle handled of having carried out stapling together.Relative with it, in this example, after the processing of stapling together, make exit roller up and down 74 be crimped status, thereby can clamp the recording chart bundle of stapling together after handling effectively, can under this state, carry out migration processing.Thus, no matter be a recording chart of handling stapling together, still the recording chart bundle to having carried out stapling together and handling all can similarly carry out migration processing.

(slip of the unit 70 of stapling together)

In addition, this to the unit 70 of stapling together mobile the describing on the direction of sheet transport direction.In this example, the unit 70 of stapling together moves back and forth along sheet transport direction with the bottom 89 of row's paper disc 8 described later and row paper disc 8 belows.In addition, the direction that the unit 70 of stapling together is slided is the direction along paper width direction.

Between the bottom of the unit 70 of stapling together and apparatus main body 90, slidingtype guide rail 75 is set.Slidingtype guide rail 75 for example can be the slide rail that Accuride (registered trademark) etc. has used ball.Specifically, make slidingtype guide rail 75 have holding member, this holding member is at the guide rail that is installed on 70 bottoms, unit of stapling together and be installed between the outer guide rail of adorning on 90 of apparatus main body and keep ball.The guide rail of unit 70 sides of stapling together slides via the outer guide rail of adorning 90 sides of ball with respect to apparatus main body, thereby can staple together the smooth slip of unit 70 with respect to apparatus main body.

Usually, staple together unit 70 be configured to be fixed on apparatus main body on punch unit 60 contact.On the other hand, take place under the situation of paperboards at main transport path 51 or revolution transport path 52, carry out the replacing of staple, additional situation is inferior, make staple together unit 70 along sheet transport direction downstream side slide.By this slip, as shown in Figure 7, form the space between unit 70 and the punch unit 60 stapling together.It is good that thereby identity becomes, and can put into hand in this space and carry out operation.Its result can easily take out at main transport path 51 or the recording chart that blocks of revolution transport path 52, can easily carry out the paperboard processing operation.In addition, the operation that also can easily change, replenish staple.

And, at this moment, the distance that the unit 70 of stapling together can slide to the sheet transport direction downstream, to greatest extent for the end in the sheet transport direction downstream of the unit 70 of stapling together not from the outstanding distance in the side of compounding machine 1.That is, the unit 70 of stapling together can not slide in the outstanding scope from apparatus main body in the end in sheet transport direction downstream.So to the slidably scope setting restriction of unit 70 of stapling together, slidingtype guide rail 75 can not produce distortion etc.

As mentioned above, staple together unit 70 be configured to usually be fixed on apparatus main body on punch unit 60 contact.At this moment, staple together unit 70 shown in Fig. 8 (a), fasten with the buckling groove 66 that is arranged on the punch unit 60 by the hook 76 that is arranged on the unit 70 of stapling together, and be fixed on the punch unit 60.It can be that rotate at the center with rotating fulcrum 76a that hook 76 is set to.In addition, hook 76 is applied in acting force on the direction that with rotating fulcrum 76a is middle mind-set clockwise direction rotation.Hook 76 leading section 76b is formed roughly L word shape to fasten with buckling groove 66.And another of hook 76 is distolateral to be connected with hook bar 77.

The following unit 70 of stapling together that makes slides to the sheet transport direction downstream.Operation hook bar 77 makes hook 76 resistant function power and is the counterclockwise backward rotation of middle mind-set with rotating fulcrum 76a, removes the fastening of hook 76 and buckling groove 66.Thereby the unit 70 of stapling together is moved to the sheet transport direction downstream.By the unit 70 of stapling together is moved to the sheet transport direction downstream, can easily carry out paperboard processing operation etc. as mentioned above.

On the contrary, after paperboard processing operation etc. finished, the following unit 70 of will stapling together was fixed on the punch unit 60.Make the unit 70 of stapling together to the slip of sheet transport direction upstream side and near behind the punch unit 60, shown in Fig. 8 (b), the leading section 76b of hook 76 and the dip plane 66a butt of buckling groove 66.From this state the unit 70 of stapling together is slided to the sheet transport direction upstream side, thereby shown in Fig. 8 (c), link up with 76 resistant function power and be that middle mind-set is counterclockwise rotated with rotating fulcrum 76a.The unit 70 of stapling together is slided to the sheet transport direction upstream side, thereby link up with the 76 summit 66b that cross buckling groove 66, shown in Fig. 8 (a), hook 76 fastens with buckling groove 66.Thus, the unit 70 of stapling together is fixed on the punch unit 60, and the unit 70 of stapling together becomes and can not move to the sheet transport direction downstream.In addition, also can on the unit 70 of stapling together, buckling groove be set, on punch unit 60, hook be set.

(lid 50)

Lid 50 as mentioned above, can be arranged on with opening and closing paper aftertreatment portion 5 in face of on the face of side.The rotation axis 50a that lid 50 can be provided with its bottom is that rotate at the center.As Fig. 3～shown in Figure 5, lid 50 under closing state, arranged perpendicular and cover paper aftertreatment portion 5 in face of the face of side.On the contrary, as Fig. 6, shown in Figure 7, lid 50 is under the state of opening, and the configuration of approximate horizontal ground is also opened the side in front of paper aftertreatment portion 5.So, behind the uncap 50, side-draw goes out perforation bits accommodating container 63 in the presence of, handles the perforation bits in the perforation bits accommodating container 63.

Lid 50 forms and main is considered as rectangle, and form can cover punch unit 60 and the unit 70 of stapling together in face of whole size of side.Be formed with on the lid 50 to inboard (private side of paper aftertreatment portion 5) outstanding projection 50b, after the close cap 50, this projection 50b and the fastening hole portion that is formed on the unit 70 of stapling together fasten, thereby lid 50 is fixed in the paper aftertreatment portion 5.In addition, also be formed with side-prominent inwards projection at the outward flange of lid 50, after the close cap 50, the end butt of the face of side in face of the projection of lid 50 and punch unit 60 and the unit 70 of stapling together.Wherein, the projection 50c that forms on the end of unit 70 sides of stapling together is provided with projection as the staple together restriction of position of unit 70 of restriction.

Limit with projection 50c and the restriction that on the end of the sheet transport direction upstream side of the face of side in face of the unit 70 of stapling together, forms slot part 70c butt.As shown in Figure 9, under vertical view, restriction projection 50c and the bearing surface 50d of restriction with slot part 70c are not in (direction shown in the single-point line among Fig. 9) formation abreast on the direction of paper width direction, but with respect to the direction tilt angle alpha along paper width direction.So, restriction,, along with close front (along with the private side near paper aftertreatment portion 5) and narrows down at the width on the direction of sheet transport direction gradually with projection 50c.On the other hand, the restriction of the unit 70 of stapling together is forming on the direction of paper width direction under vertical view abreast with the bearing surface 70d of slot part 70c side.

By being set, above-mentioned restriction has following advantage with projection 50c on lid 50.As mentioned above, the unit 70 of stapling together is set to fasten with respect to punch unit 60 and breaks away from.And by the hook 76 of the unit 70 of stapling together and buckling groove 66 fastenings of punch unit 60, the unit 70 of stapling together is fixed on the punch unit 60.At this moment, boundary surface 60f each other, 70f are relative.But the leading section 76b of hook 76 crosses the summit 66b of buckling groove 66, and hook 76 and buckling groove 66 are fastened, and therefore produces the gap between boundary surface 60f, 70f each other.

In this example, the unit 70 of stapling together is slided to the sheet transport direction upstream side, hook 76 and buckling groove 66 are fastened, and after having fixed the unit 70 of stapling together, close cap 50.At this moment, rotate and close cap 50 after, the restriction of lid 50 is with the restriction usefulness slot part 70c butt of projection 50c with the unit 70 of stapling together.And then, after the close cap 50, restriction with projection 50c and restriction with the butt position of 70c not, along the inclination of restriction, and gradually to side shifting in front with the bearing surface 50d of projection 50c.Thereby the unit 70 of will stapling together is pressed into punch unit 60 sides.And, above-mentioned projection 50b and the 70b of fastening hole portion are fastened, fully after the close cap 50, the boundary surface 70f of the unit 70 of stapling together near to and the boundary surface 60f of punch unit 60 between position very close to each other substantially, the unit 70 of under this state, fixedly stapling together.

So, with the restriction projection 50c of the end butt of the unit 70 of stapling together, when having closed lid 50, can reduce as far as possible when being arranged on close cap 50 in the gap of stapling together generation between unit 70 and the punch unit 60.Thereby can limit the fixed position of the unit 70 of stapling together, the vibration of the unit 70 that can prevent to staple together.

In addition, lid 50 is set to play the effect of switch of the ON/OFF (on/off) of the action of switching compounding machine 1.The action of compounding machine 1 each one when action of compounding machine 1 is print processing, paper aftertreatment etc., when lid 50 was closed, the action of compounding machine 1 was connected, and various processing such as print processing, paper aftertreatment are allowed, can carry out.On the contrary, when lid 50 was opened, the action of compounding machine 1 disconnected, and various processing such as print processing, paper aftertreatment are under an embargo, and can not carry out.So, along with the switching of lid 50, switch the on/off of the action of compounding machine 1.In addition, when request is printed, under the situation that lid 50 is opened, the user is pointed out with close cap 50.

By the lid 50 play this on/off switch effect is set, under the state when the replacing/adjunctive program that carries out paperboard processing operation, staple etc., that lid 50 is opened, can not print processing, paper aftertreatment etc. in paper aftertreatment portion 5.Thereby can guarantee to have the security of the compounding machine 1 of paper aftertreatment portion 5.

In addition, in compounding machine 1, except lid 50, also be provided with the door of switching.Therefore, can be under the state of the door Close All of the compounding machine 1 that comprises lid 50, the action of compounding machine 1 is connected, and under any one state of opening of the door of the compounding machine 1 that comprises lid 50, the action of compounding machine 1 disconnects.

(conveying of the recording chart in the paper aftertreatment portion 5)

Next the conveying to the recording chart in the paper aftertreatment portion 5 describes.As mentioned above, in paper aftertreatment portion 5, be provided with main transport path 51 and revolution transport path 52.

From the distributing roller 36e of apparatus main body through perforation unit 60 distributing roller 54 until the middle part that is disposed at the unit 70 of stapling together, form main transport path 51.Recording chart after the print processing that distributing roller 36e along this main transport path from apparatus main body discharges finishes is transported to the staple together platform 72 or the revolution transport path 52 of the unit 70 of stapling together.Under the situation of the selection of when asking to print, handling, after double-side printing processing or the end of unit print processing, the recording chart that transports on main transport path 51 is stopped on the guided plate 62 as print conditions existence perforation.And the perforation that makes punch block mechanism portion 61 descends with tapping machine 64, at the enterprising eleven punch 11 in precalculated position of the rearward end of recording chart.

Revolution transport path 52 is formed at the top of the unit 70 of stapling together, and 55 form this revolution transport path 52 from distributing roller 54 to revolving roll.Main at revolution transport path 52, with recording chart when distributing roller 54 is transported to revolving roll 55, under the state of the rearward end of clamping recording chart by revolving roll 55, retrograde rotation revolving roll 55.Thereby make recording chart counter-rotating, and from revolving roll 55 to distributing roller 54 feeding recordable papers.

Revolution transport path 52 uses two-sided the printing when handling to recording chart.That is, when in compounding machine 1, carrying out duplex printing,, be directed to revolution transport path 52 from the main transport path 36 of apparatus main body through main transport path 51, and make it to reverse by this revolution transport path 52 with the recording chart that is through with to the print processing on surface.And the recording chart after will reversing again is transported to the main transport path 36 of apparatus main body from revolution transport path 52 through main transport path 51, and then is directed to counter-rotating transport path 37, and the reverse side of recording chart is printed processing.Be through with to the recording chart of the print processing of reverse side, be discharged to the platform 72 of stapling together of the unit 70 of stapling together from the distributing roller 36e of apparatus main body through main transport path 51.

On the other hand, recording chart two-sided do not printed when handling, promptly only the single face of recording chart is printed when handling, will be through with to the recording chart of the print processing on surface from main transport path 51, directly be discharged to the platform 72 of stapling together by distributing roller 54, and be not transported to revolution transport path 52.

Revolution transport path 52 so is set in the unit 70 of stapling together, and carries out the revolution of recording chart by the revolution transport path, thus with use the roller that recording chart is discharged to paper disc 8 to carry out rotating situation to compare, can shorten the fed distance of recording chart.Therefore, can improve the printing effect of compounding machine 1 when carrying out duplex printing.

In addition, in this example, from distributing roller 54 to stapling together the platform 72, do not form the transport path of main transport path 51, revolution transport path 52 and so on, recording chart is discharged under the state of bending from distributing roller 54.Therefore, when under the state of clamping recording chart with distributing roller 54, turning round, may on recording chart, produce fold etc.Therefore, in this example, carry out the revolution of recording chart, but revolution transport path 52 is set, can prevent from recording chart, to produce fold etc. without distributing roller 54.In addition, not forming revolution transport path 52 in the punch unit 60 of the upstream side that is disposed at the unit 70 of stapling together, is because dispose punch block mechanism portion 61 on the top of punch unit 60 as mentioned above.

The conveying of above-mentioned recording chart can be undertaken by the rotational action of the branch's pawl 53 on the link position (branch location of main transport path 51 and revolution transport path 52) of downstream that is disposed at main transport path 51 and the upstream side that turns round transport path 52.Branch's pawl is set to and can freely rotates between following two positions around transverse axis: the primary importance among Fig. 2 (position shown in the solid line); Open the second place (position shown in the double dot dash line) of revolution transport path 52 with rotating from this primary importance clockwise direction to Fig. 2.And, when branch's pawl 53 is positioned at primary importance, recording chart can be discharged on the platform 72 of stapling together, when being positioned at the second place, recording chart can be transported to revolution transport path 52.In addition, primary importance is the initial position of branch's pawl 53.

Exist as print conditions when request is printed under the situation of selection of single face print processing, branch's pawl 53 is positioned at primary importance, and the recording chart after printout surface finishes is directed into the platform 72 of stapling together.On the other hand, when having the selection of double-side printing processing as print conditions when request is printed, the front end of the recording chart that the print processing on surface is through with is through behind the fixation unit 39, and branch's pawl 53 is switched to the second place from primary importance.Thereby the recording chart after the printout surface end is directed to revolution transport path 52.In addition, the front end of the recording chart that the print processing of reverse side is through with is through behind the fixation unit 39, and branch's pawl 53 is switched to primary importance from the second place.Thereby the recording chart after the end of reverse side print processing is directed to the platform 72 of stapling together.

And then, when printing, request exists under the situation of the selection handled of stapling together as print conditions, recording chart is discharged to when stapling together platform 72, and the rearward end of recording chart is shaken the branch's pawl 53 that is positioned at primary importance after leaving from distributing roller 54.Carry out shaking of this branch pawl 53 for several times repeatedly, leave and drop to the rearward end of recording chart of platform 72 of stapling together downwards thereby beat from distributing roller 54.Thereby recording chart arrives the platform 72 of stapling together rapidly.

Staple together as mentioned above when handling, be discharged to the recording chart of the platform 72 of stapling together, because of deadweight is tilted to the landing of sheet transport direction upstream side along the platform 72 of stapling together.At this moment, in the recording chart landing midway, next recording chart is discharged from, and when two recording charts were overlapping, the recording chart of downside may be followed landing.Therefore, wait for that recording chart is slipped to the end of the platform 72 of stapling together, discharge next to the platform 72 of stapling together again and open recording chart.Therefore, need to wait for that recording chart is slipped to the time of the end of the platform 72 of stapling together, the printing effect variation of compounding machine 1.Therefore, in this example, shake the rearward end that branch's pawl 53 beats recording chart, thereby shorten the time that recording chart is slipped to the end of the platform 72 of stapling together as far as possible, improve the printing effect of compounding machine 1.

The recording chart of discharging to the platform 72 of stapling together from distributing roller 54, from its front end gradually with platform 72 butts of stapling together.And, to discharge midway from distributing roller 54 at recording chart, the leading section of recording chart arrives the exit roller 74 in the downstream of the platform 72 of stapling together.Whether the conveying of recording chart is afterwards stapled together by the unit 70 of stapling together according to and to be handled and different.

Do not staple together when handling, exit roller 74 is in crimped status up and down, so paper disc 8 is carried and be discharged to recording chart by exit roller 74.At this moment, when having the request of migration processing as print conditions when request is printed, recording chart is undertaken being discharged to paper disc 8 after the migration processing by above-mentioned exit roller 74.

Relative with it, when stapling together processing, exit roller 74 is in released state up and down.Therefore, can not carry by exit roller 74 even recording chart is transported to the leading section of recording chart up and down between the exit roller 74 by distributing roller 54 yet.Therefore, separate from distributing roller 54 rear end of recording chart, loses after the carrying capacity in sheet transport direction downstream, and recording chart is tilted to the landing of sheet transport direction upstream side because of deadweight along the platform 72 of stapling together.Its result carries out the location of sheet transport direction to recording chart.

And, the recording chart of predetermined number from distributing roller 54 discharge and be adjusted be loaded on the platform 72 of stapling together after, by the portion of mechanism 71 that staples together in the processing of stapling together of the rearward end of recording chart.When this stapled together processing, the middle part of recording chart was between the exit roller up and down 74 of released state.After the processing of stapling together finishes, make exit roller 74 crimping up and down, drive exit roller 74 the recording chart bundle is discharged to paper disc 8.At this moment, exist as print conditions when request is printed under the situation of request of migration processing, recording chart is discharged to paper disc 8 after carrying out migration processing by above-mentioned exit roller 74.

At this, as mentioned above, therefore exit roller 74 exists following advantage all as the driven roller setting up and down.In this example, discharge the recording chart bundle of stapling together after handling with exit roller 74, but if only drive one of exit roller 74, and make another driven this moment, then the number of recording chart bundle is many more, and the rotation of driven roller is difficult to be delivered to driven voller more.Its result may cause recording chart in the position breakage with staple.Relative with it, exit roller 74 is driven roller by making up and down, thereby can not damage recording chart, can successfully recording chart be discharged to paper disc 8.

(row's paper disc 8)

Next row's paper disc 8 is described.

Row's paper disc 8 is arranged among the inner space C of " コ " word shape that the apparatus main body by compounding machine 1 forms with said apparatus aftertreatment portion 5.On row's paper disc 8, discharge and having carried out in paper aftertreatment portion 5 that perforation is handled, the recording chart of the paper aftertreatments such as processing of stapling together.Row's paper disc 8 is set to can be flexible along sheet transport direction (the discharge direction of recording chart).But also be set to oscilaltion.And then be set to and slide with respect to apparatus main body.

As Fig. 3, shown in Figure 5, row's paper disc 8 be formed can flexible on the direction of sheet transport direction be 1 section～3 sections dish.In this example, the structure of row's paper disc 8 is manually to be stretched along sheet transport direction by the user according to the print paper size.

Row's paper disc 8 is provided with first row's paper disc 81, second row's paper disc 82 and the 3rd row's paper disc 83.First row's paper disc 81 is maximum sized dishes, dispose the most close paper aftertreatment portion 5.First row's paper disc 81 forms not the outstanding length in side (sidewall) from compounding machine 1.This first row paper disc 81 is set to and can not moves to the direction along sheet transport direction.

Second row's paper disc 82 is dishes of intermediate sizes, is accommodated among the containing section 81a that is formed on first row's paper disc 81.This second row paper disc 82 be set to can along the direction of sheet transport direction enterprising retire moving.The 3rd row's paper disc 83 is dishes of minimum dimension, is accommodated among the containing section 82a that is formed on second row's paper disc 82.The 3rd row paper disc 83 be set to can along the direction of sheet transport direction enterprising retire moving.

As shown in Figure 3, to arrange under the state that paper disc 8 only is punctured into 1 section, row's paper disc 8 is in the length minimum on the direction of sheet transport direction, and the 3rd row's paper disc 83 is accommodated in second row's paper disc 82 fully, and this second row paper disc 82 is accommodated in first row's paper disc 81 fully.At this moment, row's paper disc 8 is in the length on the direction of sheet transport direction, with first row's paper disc 81 in the equal in length on the direction of sheet transport direction, be outstanding length not from the side of compounding machine 1.So, be under the state that shrinks most at row's paper disc 8, it is not outstanding from apparatus main body, thereby when not using compounding machine 1, row's paper disc 8 can be accommodated in the space of apparatus main body.

Relative with it, as shown in Figure 5, upholding at the row's of making paper disc 8 is under 3 sections the state, row's paper disc 8 becomes maximum in the length on the direction of sheet transport direction, second row's paper disc 82 is outstanding to greatest extent from first row's paper disc 81, and the 3rd row's paper disc 83 is outstanding to greatest extent from this second row paper disc 82.At this moment, row's paper disc 8 is in the length on the direction of sheet transport direction, greater than the length of maximum sized recording chart on sheet transport direction that can print in compounding machine 1.Thereby when row's paper disc 8 is upheld to maximum length, even printable maximum sized recording chart also can stably load.As described below, row's paper disc 8 can slide with the unit 70 of stapling together, but is being mounted with under the state of recording chart, even row's paper disc 8 slides, recording chart can not fall from row's paper disc 8 yet.

As mentioned above, row's paper disc 8 is set to can be flexible on the direction of sheet transport direction, therefore can will arrange the size that paper disc 8 is adjusted to the best according to the print paper size and use.

In addition, as shown in Figure 3, Figure 4, row's paper disc 8 be formed can lifting on above-below direction dish.In this example, row's paper disc 8 carries out lifting according to the amount (number) of the recording chart that loads.

Be discharged to the amount of the recording chart on the paper disc 8, detect by near the upper limit sensor the exit roller 74 that is located at downside 84.This upper limit sensor 84 is set to the sensor of contact.And the highest of the recording chart on the row's of being loaded in paper disc 8 when arriving predetermined height, upper limit sensor 84 is connected.Thereby the row's of detecting paper disc 8 is full of.Be full of detection by this and will arrange the distance that paper disc 8 descends and is scheduled to.By the decline of this row's paper disc 8, upper limit sensor 84 disconnects.Upper limit sensor 84 switches on/off like this, detects the amount of the recording chart on the row's of being loaded in paper disc 8 thus.In this example, with the initial position of row's paper disc 8 lifting position (position shown in Figure 3) as row's paper disc 8, with the end of the upstream side of row's paper disc 8 be configured in exit roller 74 under.And along with the increase of the amount of the recording chart that loads, row's paper disc 8 descends gradually.In addition, also upper limit sensor 84 can be set to optical sensor.

Row's paper disc 8 is set to as mentioned above and can stretches, but when its lifting moving, by the lifting of first row's paper disc 81, second row's paper disc 82 and the 3rd row's paper disc 83 and these first row paper disc, 81 1 liftings.

For example following the carrying out of lifting of first row's paper disc 81.Be provided for the drive division 85 of lifting moving first row's paper disc 81 in the inboard of first row's paper disc 81.Taken in rotating band (not shown) in this drive division 85, rotating band can be by driving through the 86 not shown driving powers that connect that connect up.On drive division 85, be connected with the support component of the leading section that supports first row's paper disc 81.Support component is set to move back and forth up and down by rotating band is driven.And, via transmission of power to the first row paper disc 81 of this support component with the rotating band of drive division 85, thus first row's paper disc, 81 lifting moving.In addition, be provided with the arm 88 that supports first row's paper disc 81 in the bottom of first row's paper disc 81.Arm 88 is configured between first row's paper disc 81 and the bottom 89.And arm 88 is bent into L word shape and is provided with, and its angle of bend is variable.The angle of bend of this arm 88 changes along with the lifting position difference of first row's paper disc 81.In addition, the end of the close paper aftertreatment portion 5 of first row's paper disc 81 is provided with projection.The slot part that extends more longways up and down in this projection and setting and the paper aftertreatment portion 5 fastens, and can slide in slot part.

As mentioned above, but oscilaltion row paper disc 8, and make initial position be lifting position, thus have following advantage.When the distance between the upper and lower of row's paper disc 8 and exit roller 74 (to the drain position of row's paper disc discharge recording chart) was elongated, recording chart was discharged from the mode on the row's of dropping to paper disc 8, so the bulk property variation.But, in this example, row's paper disc 8 is descended from lifting position, thereby can shorten the distance between the upper and lower of row's paper disc and exit roller 74 as far as possible according to the amount of the recording chart that loads, keep being discharged to the bulk property of the recording chart on the paper disc 8 well.And, by the decline of row's paper disc 8, can guarantee the charging capacity of recording chart to a certain extent, can effectively utilize the space of apparatus main body.

In addition, the initial position of the row's of making paper disc 8 is during for the position of the below of lifting position, from above-mentioned bulk property aspect, each when starting compounding machine 1, row's paper disc 8 need be risen to lifting position, duplicates fast and postponed, and causes printing effect to reduce.But in this example, the initial position of row's paper disc 8 is lifting position, so does not need to carry out above-mentioned rising, can not postpone quick duplicating, can prevent the decline of printing effect.

As mentioned above, row's paper disc 8 can lifting, and row's paper disc 8 below bottom 89 between be formed with space C1.And shown in Fig. 3 waited, the inboard of this space C1 was blocked by above-mentioned drive division 85 grades, and side in front and the side of space C1 are opened.Therefore, in the C1 of this space, for example may place following article etc.: print and finish the recording chart that take out from row's paper disc 8 back; Next the predetermined recording paper of supply in the carton 33; Next the predetermined toner container of changing.But when row's paper disc 8 descends under being placed with the state of these article, may the row of damage paper disc 8 and drive division 85 etc., damage the article of placement.Therefore, in this example, use side and the side in front of the space C1 of the below of blocking parts 91,92 row's of covering paper discs 8 respectively.In addition, omitted among Fig. 1, Fig. 3～Fig. 7 and blocked parts 91,92.

Be arranged on space C1 in face of side block parts 91, its upper end be fixed on first row's paper disc 81 in face of on the part of side, its lower end is fixed on the bottom 89.In addition, be arranged on space C1 side block parts 92, its upper end is fixed on the part of front of first row's paper disc 81, its lower end is fixed on the bottom 89.

In this example, because therefore the row of being provided with paper disc 8 liftably blocks parts 91,92 and is set to and can stretches according to the lifting moving of arranging paper disc 8 respectively.As the telescopic parts 91,92 that block, for example use folding curtain type, flap type.

So, with the below of blocking parts 91,92 row's of covering paper discs 8, the space C1 that the below of row's paper disc 8 forms is not opened.Thereby can prevent from the C1 of this space, to place article, therefore when row's paper disc 8 descends, can the row's of damage paper disc 8, can not damage the article of placement.

In addition, as shown in Figure 7, row's paper disc 8 can slide with respect to apparatus main body.In this example, row's paper disc 8 constitutes, and with the bottom 89 and the unit 70 of stapling together, moves back and forth along sheet transport direction.In addition, also can the row's of making paper disc 8 directions of sliding be direction along paper width direction.

The bottom 89 of the below of row's paper disc 8 is not to be fixed on the apparatus main body, but is connected with the unit 70 of stapling together.As mentioned above, the unit 70 of stapling together is set to and can slides with respect to apparatus main body, and therefore can slide with this unit 70 of stapling together in bottom 89.Bottom 89 via arm 88, block parts 91,92 etc. and be connected with row's paper disc 8, by the slip of bottom 89, row's paper disc 8 is slip together also.In addition, between bottom 89 and apparatus main body outer adorns 90, the slidingtype guide rail can be set.

(the more detailed structure of punch unit (punching apparatus) 60)

Next, with reference to Figure 10～Figure 13 the punch unit (punching apparatus) 60 as the feature of first embodiment is described in detail.

Figure 10 is the concise and to the point cut-open view that amplify the part of the more detailed structure of expression punch unit 60.

The figure middle horizontal square to arrow, be the sheet transport direction of the paper transportation path that forms by up and down paper guide 62a, 62b, in the figure, carry the paper after the print processing to the left from the right side.In the print processing request, selected the paper of the function of " perforation is handled ", in image forming part, carried out after the print processing, be discharged to paper portion via the paper transportation path among the figure, but in this course of conveying, arrived the paper of punch unit 60, utilization is disposed at punch unit 60 dead ahead line sensors (light-emitting component 36f1 and light receiving element 36f2), and the transfer position that carries out paper width direction (direction vertical with paper) detects and the detection of paper rear end.By the rear end of detection conveyance of sheets like this, calculate the sequential that stops of conveyance of sheets, determine to bore a hole and handle in the appropriate location on the direction of sheet transport direction, determine that the conveying of paper stops sequential.

Next, according to the detected value of detected paper width direction, definite perforation that constitutes punch unit 60 uses mould 65 and perforation with the appropriate location of tapping machine 64, bores a hole and uses mould 65 and perforation to use moving of tapping machine 64.This shift action is to determine that the perforation on paper width direction handles the aligned in position of position, is and aligned in position along the direction no less important of sheet transport direction.That is be, in order to make the bulk property in perforation sheet processed when filing is good, as to improve the paper bundle attractive in appearance necessary aligned in position.In addition, the perforation used in first embodiment with mould 65 and perforation with tapping machine 64, be can 2 holes with and 3 holes with between the formation changed, can suitably change by user's selection.

In addition, perforation tapping machine 64, its upper end is connected with rotating cam (offset cam) 67, drives a perforation axle 67a by not shown drive source drives and makes its rotation, thereby make rotating cam 67 rotations.At this moment, make perforation axle 67a from initial position (position shown in Figure 11 (a), Figure 11 (b)) Rotate 180 degree, thereby perforation with tapping machine 64 up and down reciprocatingly once, the processing of boring a hole.

Figure 11 (c) expression perforation axle 67a has rotated the state of 90 degree from initial position, perforation tapping machine 64, be passed in through hole 62a1 that the last paper guide 62a that constitutes paper transportation path forms, and the through hole 62b1 of paper guide 62b formation down downwards from the top, and arrival bottom.In addition, Figure 11 (d) expression perforation axle 67a has further rotated the state of 90 degree to same direction from the state shown in Figure 11 (c), perforation with tapping machine 64 pass play upward from the below paper guide 62b through hole 62b1, reach the through hole 62a1 of paper guide 62a, turn back to initial position.

In perforation is handled, begin to be undertaken by a series of action till the state shown in Figure 11 (d) from the state shown in Figure 11 (b).In addition, this perforation is handled action for existing known action, omits more detailed description at this.

Promptly, to the paper P (state shown in Figure 11 (b)) that stops at the appropriate location with respect to punch unit 60, by making rotating cam 67 Rotate 180 degree, make perforation up and down reciprocatingly once, at the assigned address formation perforation P1 of paper P with tapping machine 64 by a drive source rotation driving perforation axle 67a.Formed the paper P of perforation P1,, be transported to subsequent processing (row's paper disc portion) once more by recognizing the completed not shown control part of forming of perforation.

On the other hand, the perforation bits 130 because of perforation forms via the mould aid in guide plate 68 of the bottom that is disposed at down paper guide 62b, drop in the perforation bits accommodating container 63 that is disposed at the below.That disposes the amount of taking in that detects the perforation bits of taking in 130 in perforation bits accommodating containers (being designated hereinafter simply as " accommodating container ") 63 is full of detecting sensor 102.This is full of detecting sensor 102 can be mechanical pick-up device, but uses the optical sensor of reflection-type in the first embodiment.Promptly, a upper inside wall configuration reflecting plate 102c at accommodating container 63, form two peristomes in relative with it another upper inside wall, form light-emitting component (light emitting diode) 102a and light receiving element (photodiode) 102b in the mode towards this peristome respectively.

In the punch unit 60 of above-mentioned formation, in the first embodiment, in accommodating container 63, dispose the electric parts 120 that remove of perforation bits.

Figure 12 (a)～Figure 12 (c) and Figure 13 represent to remove the formation of electric parts 120.Wherein, Figure 13 example the formation of removing electric parts 120 under the situation about using of 2 holes.

Remove electric parts 120 and form by electroconductive component, be configured in respectively accommodating container 63 upper end open portions on the edge part 631,631 of the front and back of sheet transport direction.That is, in Figure 12 (a)～Figure 12 (c) and example shown in Figure 13, about (front and back) constitute a pair of.

Remove electric parts 120 and be formed base end part 121 and the lateral surface of the upper end-face edge portion 631 of accommodating container 63 and the shape of upper surface butt, this base end part 121 is fixed on the accommodating container 63.In addition, this base end part 121 is via not shown device frame ground connection.

And, dip down a little tiltedly near near this base end part 121 (central portion of sheet transport direction) central portion of accommodating container 63 and to extend the leading section side that is provided with, what be formed pectination removes acusector 122.

Wherein, making base end part 121 be the lid structure in the full week of the upper end open portion that is embedded in accommodating container 63 outward, can be the structure that releasably is installed in the upper end open portion of accommodating container 63.Like this throw away the perforation of accumulating consider to be worth doing 130 o'clock more convenient.In addition, in this case, with respect to the base end part 121 of lid structure, (front and back) are a pair of about only having formed removes acusector 122.

Should remove acusector 122 is configured with the interval that can capture perforation bits 130.That is, be configured: can catch perforation bits 130 (with reference to Figure 12 (b)) that get through from paper effectively, and can fall (with reference to Figure 12 (c)) from removing between the acusector 122 after removing electricity with following interval.

And then, in the first embodiment, remove in the acusector 122 with perforation and be configured to high density state 122a with the corresponding part of tapping machine 64 (that is, comprising and near the peripheral part of perforation with the relative part of tapping machine 64), part in addition can be configured to evacuate state 122b (with reference to Figure 13).When being configured like this density, can catch the perforation bits 130 of electrostatic charging state effectively in intensive part, make it can not disperse from accommodating container 63, be deposited in the perforation that removes on the acusector 122 and consider 130 quilts to be worth doing except that behind the electricity, via the part of the state of evacuation 122b, perforation bits 130 fall by deadweight easily.

At this, the reason that perforation bits are deposited in except that the part of acusector 122 is: with the cutting off of tapping machine 64, perforation is considered 130 weight because of self to be worth doing and is fallen naturally by perforation; And the electrostatic force of considering to be worth doing in 130 by perforation is adsorbed on except that on the acusector 122.

Remove electric parts 120 via device frame ground connection, therefore the perforation of absorption bits 130 are removed successively.Remove the perforation bits 130 behind the electricity, its electrostatic force descends, become be adsorbed on except that the electric field on the acusector 122 below after, fall naturally.Also there is following situation in addition: in the balance of the electrostatic belt electric weight of the vibration of the device that the action because of punch unit 60 produces and perforation bits 130, when vibration is stronger, can gets into except that the gap of acusector 122 and fall.

In addition, be formed with predetermined gap S in relative removing between the leading section of acusector 122.This gap S is formed following interval: remove at one and slide on the acusector 122 when falling, the front end that removes acusector 122 of opposition side can not be called obstruction, drops to (with reference to the perforation bits 130 of Figure 12 (c)) in the accommodating container 63 and can slide.Thereby perforation bits 130 are not only got into except that the gap of acusector 122 and are fallen, and also fall from gap S removing slip on the acusector 122.Thereby can prevent the generation of following situation more effectively: perforation bits 130 gaps that can't get into except that acusector 122, and unexpectedly be deposited in except that on the acusector 122.

So, the perforation bits 130 that fall, the sort of electrostatic force that does not have the perforation shown in the table 1 to consider to be worth doing also can not be adsorbed on the wall of accommodating container, but is deposited in the bottom of accommodating container 63.Thereby, can not become piece being full of on the detecting sensor 102, and become suitable receiving state, therefore can eliminate the flase drop that is full of detecting sensor 102 and survey.

In addition, remove the allocation position of electric parts 120, should be the top that is full of detecting sensor 102 and not with mould aid in guide plate 68 and perforation after perforation with the bottom position contacting of tapping machine 64.That is, by being configured in the top that is full of detecting sensor 102, not being adsorbed on and being full of on the detecting sensor 102 and the situation of the light path that occlusion detection is used thereby can not produce the perforation bits 130 that are deposited in the accommodating container 63.In addition, by being configured in perforation with the position beyond tapping machine 64 scopes moving up and down, can prevent because of movable perforation with the leading section of tapping machine 64 with contact the deterioration that causes except that acusector 122 except that acusector.

(second embodiment)

Next second embodiment of the present invention is described.In addition, the inscape identical with above-mentioned first embodiment is marked with identical with reference to label, with reference to the difference of the main explanation of Figure 14 (a)～Figure 16 (b) with first embodiment.

In second embodiment, in punch unit 60, remove electric parts 160 with configuration in the movable area of tapping machine 64 in perforation, should remove perforation bits 130 that 160 pairs of electric parts handle to produce because of perforation with static remove electricly, constitute by electroconductive component.

Figure 14 (a), Figure 14 (b) and Figure 15 represent to remove the formation of electric parts 160.

Should remove electric parts 160 comprises: the main part 162 of ring-type has circular peristome 161 at central portion; With many eliminations acusector 163, be set to predetermined length to the central part of peristome 161 with the predetermined space extension from this main part 162.And, remove the main part 162 of electric parts 160, under the consistent state of the through hole 62a1, the 62b1 that make two paper guide 62a, 62b and peristome 161, be fixed on down the following side of paper guide 62b.In addition, main part 162 via not shown device frame ground connection.

Thereby, when perforation is handled, perforation is pushed the perforation bits 130 after perforation is handled and is passed through peristome 161 downwards with tapping machine 64, thereby the leading section that removes acusector 163 is bend by pressure (with reference to Figure 14 (b)) downwards, its result, remove acusector 163 and contact (contacts side surfaces of using tapping machine 64 except that the side and the perforation of acusector 163 and perforation bits 130 or rather) with tapping machine 64 with perforation bits 130 and perforation.That is, when perforation descended with tapping machine 64, perforation bits 130 and this perforation of being got through with tapping machine 64 by perforation contacts with removing acusector 163 successively with tapping machine 64, bore a hole consider to be worth doing 130 and bore a hole with tapping machine 64 with static all be removed.

Thereby, can be effectively remove electricity to the perforation bits of getting through from paper P 130, perforation bits 130 can not be adsorbed on mould aid in guide plate 68, on the wall of the accommodating container 63 below being disposed at, can drop to naturally in the accommodating container 63.In addition, perforation is also removed electricity with tapping machine 64, when therefore the perforation after the perforation is risen with the perforation P1 of tapping machine 64 by paper P, can be because of the influence of static with paper P drawing to perforation tapping machine 64 sides.Thereby also can prevent to produce the distortion etc. of the perforation P1 of the paper P that causes with the drawing of tapping machine 64 because of perforation.

In addition, in second embodiment, constitute to perforation with in the movable area of tapping machine 64 outstanding be provided with remove electric parts 160 remove acusector 163, the outstanding length of therefore removing acusector 163 becomes problem.

Promptly, if outstanding length is longer, then when perforation descends with tapping machine 64, be rolled into the front end that remove acusector 163 of this perforation with the leading section of tapping machine 64, can enter into perforation with the formed spatial portion of tapping machine 64 and mould guided plate 68 (being equivalent to " perforation mould " described in the technical scheme), may cause the action of breakage, punch unit 60 bad except that acusector 163.Therefore, the outstanding length of removing acusector 163 is preferred: drop to lowest end with tapping machine 64 and when entering into mould aid in guide plate 68, can not enter into the length of above-mentioned spatial portion except that the front end of acusector 163 in perforation.
